P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 1, p. 1 EPISODE 1.1 – WHAT IS LIFESPAN DEVELOPMENT? I love teaching lifespan development. Itʼs a class that you can connect to your real life quite easily. Because we've all been children, and because we are all currently adults, and because I certainly hope we all make it several years - even decades - into the future, this class is directly relevant to everything around you: your life, your friendsʼ lives, your family of origin, the family that you have created or plan to create in the future, your friends across the world, and people you've never even met. Just because the material is endlessly relevant, that doesn't mean the content is easy to master. In fact, much of the content is really challenging, partially because all of us come into this class with a whole bunch of assumptions about human behavior. Our assumptions are biased by our own experiences, though, so we must rely on the vast store of knowledge that keeps flowing in from the empirical research to tell us whatʼs really going on in human development. What you will be learning about is things that make us completely similar to one another as members of the human species, and things that make each of us completely unique. Get used to this tension between sameness and uniqueness. In some ways, the story of lifespan development is very similar whether we are talking about an American, Kenyan, or Swedish infant. All of these children are going to utter their first words somewhere around 12 months of age, for example. But there are many different contexts and influences that have a strong impact on us as well, such as culture, socioeconomic group, education, political events, historical events, and events specific to the family in which we grew up. Do you have any brothers or sisters? If so, itʼs interesting to see if you have the same memories, impressions, and reflections on your parents. Growing up in the same family does not mean we had the same experiences. Each of us as individuals brings with us our own tendencies, our predispositions, and those special things about us evoke particular responses from our parents. If you are a parent, and especially if you have more than one child, you already know this is true. You've learned that what worked for one child may not work for the next. What one child needed may be different from what another child needed. Defining Development Lifespan development is the scientific study of how we change or remain the same in various areas of our lives from conception until death. We look to the empirical data to give us the best understanding of what's really going on during development. We use the same steps of the scientific method that you may have learned about already in a biology course or some other science class, because life span development is a science. To that end, we do things like develop and test hypotheses. We do this by collecting and analyzing data. From this data we've collected, we draw conclusions, figuring out whether the hypothesis was supported or rejected. Next, we report our results, which is probably more complicated than you think. It involves a pretty stringent process of peer review, where other scientists anonymously review the report, looking for any possible bias, alternative interpretations, omissions, or anything else they think may skew the findings. Through this process, an editorial team decides whether the report will be printed in the journal or not. Why go through all of this hassle? Scientists realize that every human being has biases, even the smartest, most careful thinkers. But most of us arenʼt fully aware of our biases. The peer review process safeguards against human bias by requiring other experts in the field to critique the work before it is published. Letʼs say the report is published. Hurray! Itʼs still not over. The results of one study are never enough for us to draw strong conclusions. A study could point us in an interesting direction, but we need to see whether future research produces similar findings. This is called replication. Were the findings replicated? This is an important question. Replication gives us confidence that the findings really are accurate. If we see the same findings across 10 different studies, for example, itʼs hard to believe itʼs just a fluke. Something real is going on. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 1, p. 2 Decades of scientific research on lifespan development have revealed themes, recurrent topics that still keep scientists busy testing new hypotheses. One theme is the nature and nurture debate. Nature is all that we are born with – our biology, our genetics. Nurture is everything else, from the prenatal environment in the womb, to parenting styles, experiences, and circumstances. The nature/nurture debate was once a debate about which one had the greater influence on development: nature OR nurture. Philosopher John Locke, writing in the 1600s, emphasized nurture. He believed that we are born as blank slates, with experience shaping who we become. In contrast, philosopher Jean Jacques Rousseau thought nature drove development. He believed we are born with everything we need to maximize our potential, and that, when things go wrong, itʼs because the environment got in the way. Today itʼs clear that genes and environment work together; they are continuously interacting, and both are equally important. Research shows us that nature and nurture are even more complicated than we ever thought. Take genetics, for example. Scientists predicted that there must be at least 100,000 different genes in the human genome to account for all the amazing diversity that we see among us. Well, it turns out that they grossly overestimated that number. The Human Genome Project revealed that we actually have only 20,000 genes. On top of that, you and I are 99.5% genetically similar. Weʼre practically identical twins! How can we have so few genes, be so genetically similar, yet be so completely unique at the same time? Genes influence other genes, and you can think of your genome as the unique recipe for YOU. You and I may have the same gene, but have a different gene that interacts with it and turns into a unique characteristic. Substitute a few ingredients, and you may end up with a very different dish! There are also genes that serve the purpose of turning other genes on or off. You could have a gene that never gets expressed because you had another gene that turned it off. And perhaps even more fascinating is the fact that the environment can influence the expression of genes as well, turning some on or off. What Iʼm saying is that the environment actually influences the expression of genes. These exciting scientific advances show us just how tightly intertwined genes and environment are, and itʼs a field of study bursting with opportunities for new discoveries. The study of the continual interaction of genes and environment is called epigenetics, and youʼll hear so much more about this in this class. Another big theme has to do with changes in development, and when theyʼre most likely to occur. Critical and sensitive periods are times in development when certain changes are particularly likely to happen. Critical periods are very specific: A particular change must occur within a particular window of time. Once that window closes, there is no going back. Prenatal development contains many critical periods, times when certain developments take place. From weeks 3-8 after conception, all major body systems and facial features are developing. Mothers who consume alcohol during this time may irreparably impact the infantʼs facial features and/or brain. Fetal Alcohol Syndrome occurs in these cases, and one of the telltale signs is the unusual facial features the baby has: widely-spaced eyes, small eyelids, and a lack of a dip above the upper lip. Brain damage is also common as well. No matter what we do, once this damage has occurred, we canʼt go back and reverse it. Thatʼs a critical period. Sensitive periods are times when change is likely to occur, but the changes arenʼt as abrupt or irreversible. The window doesnʼt shut as tightly. Take attachment, the close emotional bond that develops between an infant and a caregiver. The first year of life is a sensitive period when infants are particularly responsive to parenting. Ideally, of course, parents provide sensitive care. But what if the child has lived in an poorly-run orphanage, and is adopted at the age of 2? Itʼs likely that the child will have some challenges developing an attachment to his adoptive parents, but, with patience and a lot of care, he very well may become attached. Sure, attachment would have been easier to establish if the child was with his adoptive parents for the first year of life. And yes, this makes P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 1, p. 3 things more difficult. But any potential damage from the orphanage is not irreversible. Significant change can still occur, although it depends on the adoptive parents and the genetic predispositions of the child. The window does not shut as tightly for sensitive periods as it does for critical periods, but both involve the issue of change. The third big theme of lifespan development is a mouthful: the differences-equals-deficits error. Remember how every human being is biased? This is clear looking back at the history of science, lifespan development included. For a long time, the dominant group (which was usually Caucasians) was studied, and results were assumed to apply to all others as well. When cultural differences were uncovered, it was assumed that these differences indicated deficits. In other words, those who deviated from the assumed norm were considered inferior in some way. Consider this question: Should an infant sleep in the same bed with her parents? Your response to this question is very likely influenced by your cultural background. In many areas of the world (such as India, for example) it's the norm for infants to sleep with their parents. To suggest that the infant should sleep in her own room by herself would seem barbaric and cruel. In the United States, up until very recently, the norm was that infants should sleep in a crib in a room separate from mom and dad. To suggest that infants should sleep in mom and dadʼs bed would seem harmful to the childʼs development of independence, that their self-reliance may be stunted. For many years, it was assumed that this difference indicated a deficit – that it was inferior and even dangerous for infants to sleep with their parents. Today, thankfully, scientists are more likely to investigate differences instead of assuming inferiority. In the case of infant sleep, the research tells us that there are benefits and risks to both arrangements – sleeping alone in a crib, or sleeping in bed with mom and dad. We know this because todayʼs scientists are much more aware of the value of investigating differences. If they discover interesting findings in one group, itʼs now more common that others will see if findings are replicated across different groups as well, whether culture, gender, income, or ability is the differentiating factor. By doing this, scientists help us come to a very rich understanding of many topics. Three Domains Have you ever noticed that things don't seem quite so overwhelming if we can sort data into categories? In a typical college course, you may have been required to learn 200 terms or so. That sounds like so much. But those terms are categorized into chapters, with perhaps 20 terms per chapter. This helps us make sense of a lot of information. We can do this with lifespan development, not only by organizing material in chapters, but also by considering which of the three domains of development the term fits in: biosocial, cognitive, or psychosocial. Biosocial development is about the physical development of our bodies, such as growth patterns, physical skills, and also the brain. Cognitive development refers to all of our thought processes and the ways that we reason about things, including language development and intelligence. Psychosocial development is focused on the self and the social world, including emotional development, personality, relationships, and roles. When you are studying, remind yourself of which domain the content fits and file it in the appropriate filing cabinet in your brain. Itʼs a way of organizing the material so you can recall it more easily later. These domains do overlap and influence one another, though. Biological changes may trigger cognitive changes, influencing our relationships as well. For example, as our brain matures in adolescence (biosocial), we become more skilled at abstract reasoning (cognitive), and we start to expect more from our friends (psychosocial). We look not just for people who have similar interests, but we also want friends who are honest and loyal and stick us through thick and thin. Experiences within these more intense friendships can, in turn, influence our cognitive development and the maturation of our brain. Now that you have a very broad idea of what this course entails, we will dive more deeply into the P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 1, p. 4 specifics! EPISODE 1.2 – LIFESPAN PERSPECTIVES AND THEORIES Developmental psychology was not always focused on the entire lifespan. In fact, until fairly recently, developmental psychology focused on infancy, childhood, and the teenage years (what we refer to as adolescence). The implicit assumption was that all the interesting action happens early in life, that development follows a pattern of continual gains until adulthood, and then we just live out our adult lives, kind of holding steady, until we decline in old age and eventually die. Perhaps it's understandable that adulthood wasn't given much attention back in the days when we didn't live so long. The average life expectancy in the early 1900s was about 50 years of age. We've seen a dramatic increase in average lifespan- which is now 78 in the U.S. And, the whole age structure of our population is shifting, as the proportion of those 65 and older continues to grow. In the 1960s some academic disciplines emerged that helped push us toward an awareness that development occurs across the lifespan. Gerontology focused on the factors that lead to decline or thriving in older adulthood. Life course sociology focused its attention on the events of adulthood, like marriage and parenting. Also, some ongoing studies started in the early 1900s continued as research participants progressed further into their adult lives. The conclusion? Development occurs across the lifespan. There is action at every phase! And we now know enough to describe several important insights about lifespan development, which we refer to as "The Lifespan Perspective." The Lifespan Perspective Development is multidirectional. Change happens in every possible direction. Losses and gains occur at each phase, although the balance of losses and gains shifts as we get older. Infancy is mostly about gains, and older adulthood involves many losses. Nevertheless, there still are losses in infancy and gains in older adulthood. As infants, we are born with the capability to master any language we are exposed to. It's quite remarkable. If you've ever tried to learn a second language at an older age, beyond the childhood years, you know how hard it is. But you didn't have to study really hard when you were an infant, right? Why? Infants have a remarkable ability to be able to tell the difference between slightly different speech sounds, differences that are so subtle that you and I as adults would not be able to tell the difference. You can understand why this would be useful; it helps the infant figure out whatever language they are exposed to. Infants begin to lose this ability at about nine months of age, and it's a loss that actually adaptive. What's happening is the infant's brain is growing specialized toward the native language, which obviously helps them continue to master that language. At the same time, though, their total ease at learning languages begins to diminish. It's still much easier to learn a second language as a child rather than an adult, but never again is it as seemingly effortless as it was during those first nine months of life! So that's a loss in infancy. What about gains in older adulthood? Well, older adults do a better job regulating their emotions. Younger adults are not so skilled at this quite yet. Especially in the late teens and early 20s, emotion may still overwhelm our reasoning abilities so that it's difficult for us to adjust when were going through something really emotional. One thing to look forward to is that in older adulthood most of us will regulate our negative emotions batter. The research shows us that when older adults experience negative emotions - when they're angry, worried, upset - those emotions are lower in intensity and shorter in duration than they were in younger adulthood. Basically, we get over things a little bit faster; we can put things in perspective more readily as older adults. See? There are some things to look forward to as we age. Development is multicontextual. In other words, development is influenced by many environmental contexts, like history and socioeconomic status. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 1, p. 5 Let's talk about history first. The people who were born at about the same time as you were are referred to as your cohort. Cohort is sort of like another word for generation. That cohort grows up at about the same historical period in time, and so the historical events that are occurring are hitting them all at about the same age. Some of the most obvious examples would be the Great Depression or the 911 terrorist attack. But it doesn't have to be a salient event. For example, the role of technology in our lives is a historical factor that is most certainly affecting development. We expect things to move quickly today. We anticipate that tv shows and movies will be fastpaced, for example. I am already old enough to tell you about a cohort difference that I've experienced. I grew up watching tv shows like Little House on the Prairie. Loved it. I own several seasons on DVD, I'm not ashamed to admit! But as I watch these older tv shows today, I notice that they move really slowly. I bet that many of today's 18 and 19-year-olds, perhaps some of you, would find these shows to be excruciatingly slow. What kind of impact is that going to have a development? There are a lot of hypotheses being tested, but it's difficult to come to any conclusions while you're in the midst of the historical change. We will have to wait and see what the research shows us. Perhaps rapid-paced media will help us think faster. Or may be it will interfere with our ability to sit still, focus, and pay attention. Loads of tv in childhood is not good for anyone (and you'll learn about this later in the course), but the full impact of our media on develop remains to be discovered! Time and research will tell us. The socioeconomic context has a strong impact on development. This includes things like income, occupation, education, neighborhood of residence…those types of things. Really, what you see is that all of these factors have a strong influence on the kinds of opportunities that a child is exposed to. In high socioeconomic status families, children tend to have opportunities and advantages, such as high-quality schools and safe streets. In lower socioeconomic status families, though, children are exposed to more dangerous neighborhoods, poorer-quality schools, and other factors that often result in fewer opportunities and greater stress. This is a current topic of great importance because poverty rates are increasing here in the United States. In 2008 about 11.5% of American families were living in poverty. That's an increase from 2007, when the rate was 10.8%. That may not sound like a huge change to you, but when you look at the actual numbers of families affected it becomes clear. It's an increase of about 2 million families. From 2007 to 2008, 2 million more families found themselves in poverty. What influence will this context have on development? It has a strong impact, as you will learn about later in the class. Development is multicultural. Really, we could have talked about culture as another context, but it is so important that it deserves its own separate attention! The formal study of culture in psychology began with a Russian theorist named Lev Vygotsky. He focused on how, within a given society, the adult members of that society guide children to learn the skills and habits and abilities and interests that would most benefit them within their culture. Take shyness. It is less adaptive to be shy in the United States than it is in Eastern Asian countries like China. Most American families would worry about a child being too shy, whereas Chinese families may view it as an asset. When your cultural context values independence, as is the case here in the U.S., shyness is a detriment. But, when the culture emphasizes group harmony, shyness may be an asset. Remember the differences-equals-deficits error? We try very hard not to make that error, understanding that culture is a vital contextual influence on lifespan development. Development is multidisciplinary. Multiple disciplines (fields of study) contribute to our understanding of the ways in which we change and stay the same from conception until death. Take the discipline of genetics, for instance - it is absolutely essential to our understanding of lifespan development. Genes alone do not determine our characteristics. All of the other factors that surround our genes - from the cellular level, to the physical environment, to family interactions - influence the expression of genes. Consider the case of violence in the home. Research tells us now that there's a certain allele of a gene(that means a certain variation of a P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 1, p. 6 gene) that, when combined with violence in the family, contributes to a high risk of violent behavior. In other words, a child with this gene is more vulnerable to the influence of a violent family environment. This multidisciplinary work can help us understand why some children in a violent family become quite violent themselves - acting out, getting into trouble - whereas children in that same family do not. Other disciplines, like anthropology, sociology, and history, shed useful light on the topic of lifespan development as well. Development is plastic. Plastic. Why choose that word? Well, plastic is something that can be molded, so it's changeable. But plastic also hold its shape, so it's durable. We are interested in how changeable humans can be, given their age, experiences, and other factors. Plasticity is so central to lifespan development that it applies to all other aspects of the lifespan perspective as well. So, how plastic are we? Does it depend on our age? Does it matter whether we're talking about biosocial, cognitive, or psychosocial development? If damage has been done, like deprivation or abuse, how much recovery is possible? These questions all deal with the topic of plasticity. In general, we are most plastic when we are young. The earlier we intervene to help out a child who has a physical ailment, is in a dangerous situation, or has been deprived of attention, the more likely we will be able to help trigger significant, positive change. Consider epilepsy, a disorder that involves brain seizures. In some cases, the child's seizures are so severe that the only solution is to literally remove one of the halves of the brain. The earlier that happens in the child's life, the more likely that the child will be able to recover. If you are removed one of my hemispheres at my age, I would never regain all of my functioning. But, if you see a child who's had a brain hemispherectomy (a hemisphere removed), with the proper physical training and attention and patience and rehabilitation, in a few years time you may not able to tell that child apart from other children who have both sides of their brain. Why? Plasticity. The real estate of the brain becomes more specialized with age and experience. The more specialized our brain, the less flexible it is. The younger the individual, the less specialized the brain has become, and the more adaptable and plastic the brain will be. Plasticity decreases across the lifespan, but we keep hearing encouraging news from scientists studying this topic. "Older adult" rats in one study showed significant brain growth after having the chance to live in a stimulating environment. Plasticity happens across the lifespan, but it is especially likely early in life. Theories of Human Development I'm sure that in many of the other classes you've taken you've discussed theories, and even in our casual everyday language we might throw the word in here and there. “Well, I have a theory about why men do what they do.” And then we are talking about an opinion, right? When we discuss science, as we do in this class, we are talking about a different kind of theory. In scientific terms theories are not talking about opinions or guesses. Scientific theories make sense of a collection of findings that have emerged from the research. From theories we develop hypotheses, which are testable predictions that drive future research. As we address four main theories, remember that each looks at a different aspect of development. There is no one, unifying theory that covers it all. Psychoanalytic theory focuses on the inner drives and motives that influence our development. These drives may not be fully conscious. In fact, from Freud's perspective, most of what drives us as humans is unconscious - that means we aren't aware of these drives. Speaking of Freud, he is certainly the most famous psychoanalytic theorist. He's so famous, in fact, that people mistakenly believe he is the father of psychology, or that most psychologists are Freudians. Nope. Freud was an important figure in the history of psychology for opening our eyes to some key concepts that had not yet been considered in psychology. Before Freud, there was very little consideration of how a child's emotional experiences might influence her development. There was very little consideration of how the events of someone's life could influence their personality. And there was very little information on how we can recover from psychological problems. But and here's the big qualification I have to make - Freud's work was not scientific by today's P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 1, p. 7 standards. In the late 19th and early 20th centuries, when Freud was doing most of his work, the science of psychology was just barely beginning. There wasn't yet an established norm that required psychologists to conduct scientific research, report findings in peer-reviewed journals, and look for replication. That wasn't a formal part of psychology until the 1940s. Freud wasn't the father of psychology, but he was the father of talk therapy. He wrote up detailed case studies of the clients he saw in therapy, and this was the information he used to form his theory. We understand today that case studies, while interesting, are not truly scientific studies because they are too detailed to be generalizable to the public at large. Freud suggested a stage theory of psychosexual development considering how our unconscious drives and motives shift from one age to the next, and how certain experiences we have can leave a mark on our personality. For example, an adult who is very picky - what we might refer to as anal-retentive - was likely treated too harshly by his parents during the anal stage of psychosexual development. Perhaps his parents expected too much from him while he was being toilet trained. Remember, there is no scientific support for this idea, but the general notion that parenting impacts development is now widely supported. So we have Freud to thank for opening scientists eyes, even if the details of his theory sound odd. Erik Erikson was influenced by Freud, but was significantly different in his approach. He was interested in development across the lifespan, and he was interested in conscious conflicts (i.e., conflicts we are aware of). The main conflict of the teenage years, Erikson believed, was figuring out who you really are. "What is my identity? Who am I? What do I want to be?" We struggle to develop a sense of identity, but we also struggle against a feeling of role confusion. That's the conflict. Erikson identified eight basic stages, each with its own conflict, that we face across the lifespan. Experiences in past stages stick with us and impact on our experiences in future stages. Now that might seem dangerous because what if something bad happens? Is the rest of the lifespan ruined? No. Erikson theorized that experiences in later stages can help us rework some of the conflicts left over from previous stages. In contrast to Freud, Erikson's theory is testable, it has been tested, and much of his theory is supported by scientific, replicated research. You're going to visit with Erikson at every stage in the life span. Behaviorism is a theory that began with Pavlov's dogs and that is still very useful for understanding much of human behavior today. The focus of behaviorism was very different from that of psychoanalytic theory. Behaviorism focused on observable behavior, which is obviously quite different than the deep inner focus of Freud. Research on behaviorism has revealed a number of laws of behavior that have to do with conditioning. Conditioning is just another word for learning, and there are two main types: classical conditioning and operant conditioning. Classical conditioning started with Pavlov's research and has to do with anticipating what is to come, and operant conditioning emerged from BF Skinner's work and considers how we learn from consequences. One consequence is reinforcement. When our behavior is reinforced, we usually repeat it. Whatever we get reinforced for, we are likely to continue. Take a child's tantrum. Children throw tantrums because they want something. Parents get overwhelmed and want the screaming to stop, so they give in. What has the child been taught? "If I just make a big scene whenever they're not giving me what I want, they will give in! Hooray!" The child's tantrum behavior is reinforced when the parent gives in. Something in the environment - in this case, the parent's behavior - has shaped the child's learning. That is the main idea behind behaviorism, that the environment influences our learning in ways that are observable. What has the parent learned? Well, the parent has been reinforced as well. The parent is relieved when the tantrum is over - the screaming and yelling have stopped, and there is peace. So, it's a mutually reinforcing series of behaviors. The only problem is that the pattern is highly likely to repeat itself in the future. Nevertheless, whatever has been learned can also be unlearned if the environmental influences are changed (e.g., if the parents stop giving in). In the case of children P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 1, p. 8 and tantrums, I can guarantee change won't happen overnight! But, if the parents consistently stop rewarding the tantrums, they are likely to decrease and may even - eventually - disappear. Behaviorism contributed not only to the knowledge base in psychology but also to methodology because behaviorism was one of the earliest fields in psychology that took a very strict approach to collecting data and systematically analyzing it. Behaviorism helped shape psychology into a science. Cognitive theory is focused on our thoughts, attitudes, beliefs, language development … all things related to cognitive development. There are a couple of main theorists that we discuss in the class in regards to cognitive development: Jean Piaget and Lev Vygotsky. We will focus on Piaget in this episode. Piaget was remarkable - arguably the most influential developmental psychologist that has ever lived. Although his research was not as rigorous as we would expect it to be today, he was definitely ahead of his time in the way he investigated the workings of children's minds. Piaget was interested in how children think and how their thinking tends to be different from that of older children and adults. Children are not just miniature versions of adults, in other words, but the way that they think is fundamentally different from the way that we think. At the same time, there are some basic processes that are true of our thinking at any stage. For instance, we like to make sense of our world through schemas. Schemas are categories of experience. So you could have a schema for a chair, for dogs, for exercise. You have a schema for a college course. You know what to expect. Well, we like our world to match our schemas. We like to feel like we understand the things that are happening in our world. Whenever we're hit with a new experience, like maybe taking your first online class, we may be forced to revisit our schemas. Let's say it's your first online course. You probably operate at first from your schema for college course, but pretty soon you realize, "Wait a second! This is really different. I have to remember all of my assignments and due dates, I have to log into the website often, I have to remember to stay on top of my reading…and all without the regular reminders I get when I attend my face-to-face classes." Basically, new information throws off our cognitive equilibrium. We are off balance. This new experience doesn't quite fit our current schemas, so we might have to change our schema or create a new one. When we are able to fit the new experience into an existing schema, that's called assimilation. When the new experience is too different to fit, we have to adjust the schema or come up with a new one. This is called accommodation. Piaget believed we are born with a natural curiosity. Infants are encountering all kinds of things for the first time. We want to figure things out. We construct knowledge out of our own experiences, assimilating and accommodating as we encounter new information. This process propels us through stages of cognitive development, helping to explain, for example, why preschool children have such an odd way of viewing the world! Piaget is addressed at many stages in the life span up and through adolescence, so you will come to know him and his theory quite well. Our final theory to consider today is systems theory. We can use the broad term of systems theory to explore the multiple influences that can have an impact on development. Specifically, consider dynamic systems theory, the idea that we are operating within the midst of a bunch of overlapping systems, each of which is continually changing and influencing other systems. We have social factors, cultural factors, individual issues, genes and environment. At any point in development, in regards to any issue we are interested in learning more about, we will find that there are multiple interacting systems involved. Dynamic systems theory reminds us that the answer to almost any question in lifespan development is "It depends." Will a child growing up in a violent home become violent himself? It depends. It depends upon culture, that child's genetics, the particulars of the family environment, whether the child had at least one family member who was attentive to his needs, etc., etc., etc. It depends. There is never a simple answer for how complex psychological characteristics developed. That makes lifespan development a challenge to learn, but keeps things quite interesting along the way! EPISODE 1.3 – THE SCIENCE OF LIFESPAN DEVELOPMENT P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 1, p. 9 I know you have heard about the scientific method before, and hopefully you remember some of what you learned in general psychology. The basic point about using the scientific method is that there are a number of ways to collect data and a number of ways to learn about what's really going on with human development. It's best for science if a number of different strategies are used. Then, if we can look at the pattern of results and see that we have a lot of similar findings across different kinds of studies, that makes us even more confident about those findings. Using the Scientific Method Let's say that we are interested in studying whether violent media has an impact on child development. Do children who consume a lot of violent media tend to behave more aggressively as a result? We could look at this question through scientific observation, watching how children behave after they view violent media. We could carefully observe their behavior and mark any instances of aggression that we see. Or we could add a comparison or control group, randomly assigning kids to those different groups to see if they have different outcomes as a result. This would be an experiment, where we manipulate variables and see what impact it has on the outcome. Or, we could use surveys. If the child is old enough, we can ask the child to report how much violent media he or she consumes. We could ask parents to report on how much violent media their child is exposed to. We can also ask both to tell us about the child's behavior, looking for information on signs of aggression. If we really wanted to get fancy, we could also survey the children's teachers as well and get all of these different accounts to help us find out if there is any kind of relationship between violent media and children's aggression. Well, everything I just mentioned has been done, and the results are very consistent. Yes, violent media influences childhood behavior. Children who consume more violent media tend to behave in a more aggressive manner than other children. Media violence is not THE cause, but it is an important influence. We can be reasonably confident in this result because different studies - using observation, experimentation, and survey methods - reveal similar findings. In lifespan development though we are often particularly interested in change over time, and there are different methods to assess that as well. If we look at age-related differences in a characteristic, we want to know whether we are seeing developmental change, or whether we are just seeing a cohort effect. Consider attention span. Let's say we wanted to study attention span and we wanted to see how long a person would continue to work on some rather mundane task. Basically, how long will a person sits still and engage in this boring activity? So let's get people of different ages: 20, 30, 40, 50, 60, 70, and 80 year olds. We'll get them all to sit down individually, one at a time, work on this boring task, and see how long they'll sit there and do it. The great thing is that it doesn't take that long to collect the data, so we can make important discoveries and help advance the science of lifespan development more rapidly. Well, let's say that our study reveals that the younger participants have shorter attention spans than the older participants. Can we conclude from this that attention span increases as we age, that it's a developmental change? Not necessarily. Think about some of the cohort differences that could be involved. The group of 20-year olds grew up in a very different time than the 60-year olds or 80-year olds, for example. The 20-year olds were exposed to more media, and the media they consumed was faster-paced than that experienced by the older cohorts. So, we can't tell whether it's a developmental change, or a cohort difference. By the way, I just described a cross-sectional study, where we take groups of people from different ages, we assess them on some characteristic, and we try to come to some conclusions about developmental change. But the problem is that we can never know if the change we see is truly developmental. Maybe we are just seeing cohort differences. So, what should we do? Well, we could just follow one cohort over time. We could get a bunch of 20-year olds now, and assess them every ten years until they are 80. We would start with 20-year olds today, and keep assessing them every ten years. Now, that's developmental change! But, wait. Do the findings P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 1, p. 10 apply to other cohorts as well? We don't know. Also, how many of the original group of 20 year olds are still alive and interested in participating by the time they are 60, 70, or 80? Maybe those who are still living at 80 are just healthier overall, something that could affect our results. And, if they have participated all of these times across their life, by this point are they just getting really good at the task? I've just described a longitudinal study, a great method for assessing developmental change, but a challenge because we're looking at only one cohort. All right. How about this? Start with different age groups - 20-year olds through 80-year olds and assess each group every ten years. This is a combination of the cross-sectional and longitudinal methods, and it's a method with its own name: the cross-sequential study. This method lets you assess developmental change AND cohort differences. Problem solved, right? Not necessarily. Because we're assessing people over time, we still have the problems of people leaving the study, getting accustomed to the task, and of a potentially skewed sample at the end. There is no perfect study. Our methods of assessing change over time are imperfect, as are our methods of observation, experimentation, and surveys. The best we can do - the best any science can do - is to conduct studies in a number of different ways, and look for replication that reveals patterns of similar results. Now, in case you feel discouraged about these imperfections, I want to emphasize that it's just part of the scientific process. Science is a process of inquiry. We conduct studies to find things out. We can't possibly know enough to create a flawless study. The only way we could do this is if we already knew everything about the topic, in which case, why would we be studying it? Doing Research Right After we conduct a study and report our results, things can still get messed up. One problem is how results get interpreted, and most prominent mistake-maker is the media. The main mess-up with interpretation has to do with correlations. Take, for instance, a study that found a correlation between self-esteem and brain size. One study found that the lower one's self esteem, the smaller their brain. So, what was the title of the article in the press? "Low self-esteem shrinks brain." This would make you think that every time you feel bad about yourself, your brain gets a little bit smaller. This will certainly worsen your mood! This is a mistake. Just because two things are correlated does not mean that one caused the other. And, even if one caused the other, we don't know what the direction of effects is. Let's address the direction of effects first. If there is a cause-and-effect relationship between self esteem and brain size (and, may I remind you, we don't know that there is) which variable caused the other one to occur? Did low self-esteem cause the brain to shrink, or did brain shrinking cause low self-esteem? In addition to the direction of effects issue, there is also the possibility of a third variable. Correlations are always about two variables, and whenever we make the jump to assuming correlation equals causation we are acting as if nothing else is playing a role. How likely is that? The third variable interpretation requires us to think about other things that could be going on behind the scenes in this correlation. Maybe depression is a third variable. Perhaps depressed people have smaller brains AND lower self-esteem, for example. I couldn't tell you. We would have to investigate whether the finding was replicated, and we would have to study whether depression is related to brain size as well. The point is to remember not to assume that correlation equals causation. Pay attention to the news, and notice how often the headlines make this interpretive error. The next potential problem with research is in the hands of the scientists themselves. In order to do research right, scientists must make sure that they are conducting their studies in an ethical manner. All scientists are held to a very high standard these days, but unfortunately it wasn't always this way. The history of science is full of shameful evidence of disrespect toward study participants, and this is true of psychology, too. Since the 1960s there has been a swift and strong movement to ensure that high ethical standards are met in research. A code of ethics must be followed, and universities have institutional review boards that must approve a detailed study P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 1, p. 11 proposal before they are permitted to collect their data. The key issue is to make sure that participants are not harmed, that they understand that their participation is voluntary, that the results will be kept confidential, that any risks that they might be exposed to will be disclosed to them before they participate so they can decide whether or not they want to. This is called informed consent: the participant must be fully informed before they decide whether or not they will participate in the study. Developmental psychology research often involves infants and children, and the informed consent of the parents is absolutely necessary. If the child is old enough, his or her consent is needed as well. Now let's say the research is finished and it's time to present the results. Scientists are ethically bound to present results as accurately as possible. What if some scientist wants to make a big name for himself, and he "makes up" his data? It happens, but it is exceedingly rare. Scientists who break this ethical code are strongly reprimanded, losing their respect among the academic community for sure, and almost always losing their academic job as well. What if the scientist has been completely honest, has collected his data very carefully and accurately, but is funded by an outside agency that has an agenda? For example, what if a drug company has funded research on the effectiveness of the drug? The scientist leading that study must disclose in their report where their funding came from. If future scientists are suspicious of the findings, the report contains enough detail that they could try to replicate the study later. If the study is never replicated, the finding loses validity. If there are alternative interpretations of the findings, those need to be discussed and presented in the paper. These rules and regulations are policed pretty carefully by the journals and also by the peer review process that determines whether the results are reported in an academic journal at all. Ethical considerations also extended to our decisions about which topics we should study. Sometimes people struggle to understand why scientists are even studying a certain topic. Or perhaps people believe that some topics should never be studied because they touch upon controversial, moral issues, like sexual behavior among teenagers. Ultimately, scientists are driven by a desire to generate knowledge that will be help us live longer, happier lives. Sometimes the questions we need to have answered are difficult and make us squirm. Sometimes the findings contradict our beliefs and make us feel defensive. Sometimes the way things really are is not the way we hoped they would be, but that knowledge gives us the best chance of conquering the challenges we face across the lifespan.

We do. Did you know that scientists once believed there must be 100,000 genes in the human genome, just to account for all the diversity, But then they found out we actually have only 25,000-30,000 genes? Itʼs true. Yet somehow, with fewer genes then originally expected and so many of our genes in common, you and I turn out to be so completely different in so many ways. None of the genes that we have would be able to do anything without an environment. It takes nature and nurture. This episode will mark our first in-depth look at nature and nurture, but it will certainly not be the last. In order to get off to a good start though, letʼs cover some of the basics first. The Very Beginning - Genes Genes are segments of DNA that code for the production of specific proteins, proteins that influence everything about us, from our height to our personality. But genes are not as powerful as you may think. Or, maybe I should say, a single gene is not as powerful as you may think…but you have about 20,000 of them, give or take, and all together, with the influence of the environment as well, amazing things happen. Now, if you have Huntingtonʼs Disease, a disorder named PKU, or some other dominant genetic disorder, that one gene is extremely powerful. But hardly any genes operate that way. One gene rarely has the power to control a certain outcome. What matters more is the collection of genes you have, and the ways those genes interact with each other and with the environment. The way genes work is kind of like a recipe. The specific ingredients you use will have a strong impact on the outcome, but it also depends upon the particular mix of ingredients. For example, eggs do different things whether theyʼre paired with oil and flour to make a cake, or whipped with sugar and until you get meringue. Imagine a completely unique recipe with 20,000 ingredients – like your 20,000 genes, and think of all of the ways those ingredients might interact. That gives you a bit of an idea of how genes really work. When genes work together, we refer to this as a polygenic interaction. Back to the cake analogy. Youʼll never get a cake if you just leave the batter sitting on the kitchen countertop. Youʼll just have batter. You need to bake the batter at a certain temperature for a certain period of time. In other words, the batter needs certain environmental conditions in order to become a cake. Similarly, your genes, like those cake ingredients, do not have ultimate power and canʼt become you without environmental influences. Genes are influenced by everything that surrounds them – everything in the environment, from the prenatal environment, to nutrients, to how others interact with us. When genes and environment work together, this is called a multifactorial interaction. Let me give you an example of a multifactorial interaction. Due to genes, some of us are more vulnerable to stress than others. The genes may predispose a more rapid stress hormone response, for example. More glucocorticoids released. Those who are predisposed will find that they feel stressed out easily. Regardless, we do have some control over our stress reaction – we can learn how to relax or meditate, and perhaps we could even take medication for anxiety. But the one thing thought to be unchangeable was the genes. Recent research suggests this is an inaccurate view. Research on rats suggests that the environment can actually trigger changes in the expression of genes. Rats get stressed out, too. And they are similar enough to us genetically that we can learn important things from them. Some rats are predisposed to high stress rates because of genes that code for the production of glucocorticoid receptors in the brain. But the behavior of rat moms has been shown to actually change the expression of those genes. Mothers who regularly P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 2, p. 2 nurture their rat pups through licking trigger a change in the expression of genes related to stress hormones. Furthermore, scientists at McGill, a college in Canada, chemically manipulated rat pup genes and found that their stress response changed as well. Basically, through environmental influence, these scientists changed the expression of genes. Once they figure out how it all works, the hope is that it might one day be possible to help stress-prone humans by manipulating the expression of their genes as well. Perhaps highly nurturing parenting is already influencing the expression of genes in ways that we have not yet been able to detect in humans. The point to remember is that everything around the gene – other genes, hormones, environmental factors – may influence the expression of the gene. This is epigenetics. Epi means “around”, so epigenetics means “around the genes.” Already, epigenetics is affecting the way we think about medicine. Instead of a one-size-fits-all approach, perhaps we will move to a model where an individualʼs genes dictate which medications will be most effective. For example, there are certain types of cancer that are triggered because a gene that normally functions to stop a tumor from growing is shut off by another gene, a regulator gene. And, at the same time, other genes that promote the growth of the tumor are turned on by a different regulator gene. These are polygenic interactions, by the way. Medicine is being developed right now, designed to help shut off the cancer-promoting gene and turn on the cancer-inhibiting gene. Itʼs like tweaking a recipe to get things just right. In the meantime, through this research weʼre going to learn much more about how a genotype results in a phenotype. Genetic Diversity Remember how I talked about the pull between sameness and uniqueness that youʼd hear a lot about in this class? Well, here it is again. Letʼs talk about the similarities and differences we see among biologically related siblings to get a picture of the genetic diversity and sameness that exist. Have you ever noticed that biological siblings may seem both incredibly similar to one another and incredibly different from one another as well? In some respects, you would have no trouble figuring out that Iʼm related to my sister and two brothers. But each of us could quickly tell you exactly how we differ as well, as could our parents! Look, if youʼre like most people, you donʼt necessarily want to think about your parentsʼ gametes, but letʼs do so anyway. Itʼs mind-boggling if you do the math. Out of their 46 chromosomes, Mom could make about 8 million unique ova, and dad could make about 8 million unique sperm. And for you, just one of those sperm and one of those ovum combined. You got 10,000 genes from mom, and 10,000 genes from dad. So did your biological siblings. But who knows WHICH 10,000 they got and which you got. Some may be the same as yours, but others are undoubtedly different. This is true for fraternal twins as well, who are no more genetically similar to each other than any other two siblings in a biological family. We call them dizygotic twins because they came from two zygotes. A zygote is a fertilized egg, the very first step in prenatal development. Dizygotic twins happen when two zygotes form at the same time. Mom released two ova, and two of dadʼs sperm were able to fertilize them. Why would Mom release more than one ovum? Some women are genetically predisposed to this. Also, women nearing the end of their reproductive years may have cycles where two ova are released (and, perhaps, then cycles where none are released – the point is that ovulation becomes more erratic as we age). And then also today, reproductive technology has increased the incidence of fraternal twin births. For identical twins it all starts with one zygote, so we call them monozygotic twins. They have the same DNA (meaning they have the same genotype), but they will not have exactly the same phenotype. They may have been exposed to slightly different prenatal environments, based upon P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 2, p. 3 whether they shared the same placenta or not. Not all identical twins share the same placenta. Also, they may have had different experiences outside of the womb that could interact with those genes in different ways. Think about how multifactorial interaction could affect the development of biological siblings. If theyʼre not monozygotic twins, then each child is genetically unique, right? And letʼs say that each child was raised by the same two parents. The type of parenting each child receives is not just a matter of the parents though; itʼs also a matter of the child. Different children require different approaches, in large part due to each childʼs genetic predispositions. A difficult child with colic elicits a difference response than a calm baby who sleeps through the night at 2 months of age. An outgoing, boisterous, and daring toddler triggers a very different response from parents than a quiet and reserved toddler. Itʼs my hope the next time you are having a conversation with someone about whether genes or environment makes a person have a certain characteristic, you will say, “Itʼs always both!” EPISODE 2.2 – PRENATAL DEVELOPMENT We never see more rapid and fascinating development than what occurs during the 38 weeks of pregnancy after sperm meets egg. From Zygote to Newborn It takes 38 weeks to make a baby, from zygote to newborn. Sometimes youʼll hear people talk about a 40-week pregnancy. Whatʼs the difference? It depends on when you starting counting. If you start with the date of the womanʼs last period, itʼs a 40-week pregnancy; if you start with the date of conception, itʼs a 38-week pregnancy. Sometimes doctors prefer to use the 40-week schedule because they feel that day of the womanʼs last period is more easily determined than the exact day conception occurred. It could take several days for sperm to reach the egg, so just because a couple had sex, it no way indicates that thatʼs the day conception occurred. In fact we can be pretty confident that is not the day that conception occurred. We follow the scientistsʼ lead in this class, referring to a 38-week pregnancy that can be broken down into three distinct periods of development: zygotic, embryonic, and fetal. This isnʼt the same thing as trimesters, by the way, although itʼs easy to learn how they overlap: All three prenatal periods – the zygote, the embryo, and the fetus – occur during the first three months, the first trimester. The last period, the period of the fetus, begins during the first trimester, yes, but extends from the end of the first trimester all the way through to birth. The nice thing about prenatal periods, in contrast to trimesters, is that they are divided by the activities going on. The period of the zygote extends from conception to implantation, the period of the embryo involves the beginnings of all major bodily systems (organs, circulatory system, etc.), and the period of the fetus is when all major body systems become fully functional. Letʼs talk more in depth about each. Most pregnant women donʼt even know theyʼre pregnant until after the germinal period has passed. Nausea and other symptoms of pregnancy typically donʼt begin until after the zygote has become embedded in the uterus lining around 2 weeks after conception (and this is the event that ends the germinal period). But, rewinding a little bit, after conception and prior to implantation, the main action of the germinal period is cell division. Lots and lots of cell division. Very early on, before the zygote reaches the 8-cell stage, the cells could become anything at all. They are called stem cells. Scientists hope someday to be able to use stem cells to generate cells to cure many of our most vexing disorders and diseases. After the 8-cell stage, DNA instructions for the cells kick in, and cells start to differentiate (specialize) and then move where they are needed. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 2, p. 4 The embryonic period follows the germinal period. It begins once implantation is completed, which is around two weeks, and lasts through week 8. Remember, weʼre still in the first trimester here. Some women will experience “morning sickness” during this time, although itʼs really more accurate just to call it nausea because many women feel it at different times of the day. Some women will not even experience much nausea at all, or any. Others may notice their sense of smell or taste becomes unbearably acute, which, in it itself, can also bring on feelings of nausea! The embryo is really busy developing the start of all major body systems. The cardiovascular system begins to function. All organs get their start. Regardless of gender, the embryo at this point in time has a genital tubercle right now, which is a little flap of tissue between the legs that will develop into the sexual organs during the fetal period. Throughout pregnancy, development proceeds in a proximodistal fashion, meaning that the inner parts (organs) are maturing earlier than the outer parts (fingers). Moving along onto the fetal period. The fetal period is long. It lasts from 9 weeks to 38 weeks. Notice again the start of the fetal period is within the first trimester and then it extends throughout the entire remainder of the pregnancy. The fetal period is a time for all major body systems and organs to gradually, gradually reach maturity. Fetuses with chromosomes XY develop testes, which begin to produce testosterone, which turns the genital tubercle into male sexual organs and influences brain development as well. You know that sense of ʻI am a boyʼ or ʻI am a girl,ʼ that the vast majority of us just feel when we donʼt have confusion about our gender? That has to do with the way that hormones influence our brains during prenatal development. A very small portion of individuals have different experiences where their hormonal production during this time is not gender typical. That can help you understand why a person can honestly feel like they are a different gender then their body dictates. But like I said, for the majority of us this all lines up together. The testosterone influences the development of organs, and also influences brain development. Without testosterone, female sex organs develop and a female-ish brain develops as well. By the way, let me just stop here though and clarify that although there are some differences between the male and female brain, there are fewer differences than you probably think, Weʼll talk about what things differ and what things donʼt across the semester. The fetus experiences dramatic growth, from .25 oz (on average) at week 8 to 7.5 lbs (on average) at week 38. Fat layers develop near the very end of the pregnancy as well. The organ that takes the longest to develop is the brain, as neurons are created, sent to their designated positions, and begin making connections with other neurons. Brain development progresses gradually from back to front, so gradually, in fact, that the very front portion of the cortex (the prefrontal cortex) does not become fully mature until late adolescence or early adulthood! Prenatal development, in general, is cephalocaudal, meaning that the brain is a priority. The age of viability, a time when a preterm baby might be able to survive outside of the womb, is determined largely by brain development. This occurs somewhere between 22-26 weeks after conception, so thatʼs during the fetal period. Thinking about the cephalocaudal development, the priority of the brain, notice how the proportion of the fetusʼs body is so different from ours, with a huge head compared to the rest of the body. That huge head is containing that prioritize brain. Eventually, as the infant develops into childhood, the rest of the body will catch up to the brain and we will see more adult-like proportions. The priority of brain development, and our enormous heads that go with it, can make birth much more difficult for us compared to other species. And, the fact that we walk upright (instead of on all fours) led us to evolve with more narrow hips than our primate ancestors. A large fetus head and narrow maternal hips = a challenging birth. Luckily, in the vast majority of cases today, birth proceeds with a hitch. Although this certainly was not the case in the past when it was much more common for the mother or the baby or both to die during childbirth. Thankfully we have csections and other medical interventions to help if there are problems during birth. Some, though, would suggest that the modern hospital birth, with hormones used to hasten contractions, etc., P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 2, p. 5 may actually prolong and complicate the birth process and lead to more c-sections than would be necessary. Itʼs true that c-section births have increased, and thatʼs something to be aware of and to keep investigating, but itʼs also true that without procedures like c-sections, many lives wouldʼve been lost. Complications One troubling aspect of the birthing experience in the United States is the increasing rates of babies born weighing less than 5.5 lbs, a marker for low birthweight. A low birthweight baby may be preterm (born early). Some are not born early, but are born small for their gestational age. They may be 38 weeks of age, but still less than 5.5 lbs. This is often due to substance abuse (including smoking) or malnutrition thatʼs occurred during the pregnancy. In general, nurture plays a stronger role in the low birthweight experience than nature does, especially considering that rates of low birthweight are decreasing in other developed nations while they increase here in the U.S. Stress may also impact prenatal development. When a pregnant mother is extremely stressed out, her bodyʼs resources are diverted to her brain and to her muscles for survival. Itʼs like the body prioritizes things and says, “We canʼt focus that much on this developing baby in the uterus; weʼve got to make sure to keep mom alive.” So what does this mean for the motherʼs body? Well, blood flow to the uterus is decreased when a mother is extremely stressed out and the fetus, then, is deprived of oxygen and nutrients. One final reason for an increased rate of low birthweight is infertility treatments that result in multiple births. A fetus who has had to share the uterus with others is almost always smaller than one who had the whole place to him- or herself. Sometimes itʼs just a matter of space. I mentioned how substance abuse can impact prenatal development. Letʼs look more closely at things like that. Today, the idea that the developing human is affected by whatever the mother ingests or is exposed to seems obvious. But it wasnʼt always that way. For a long time, scientists incorrectly believed that the placenta shielded the developing human against harmful substances. It wasnʼt until 1941 that the first teratogen was identified: rubella (German measles). In the early 1960s, the thalidomide disaster occurred. Thalidomide was a drug prescribed to relieve morning sickness during pregnancy. Thousands of children across the world were born with limb deformities due to thalidomide. After this, scientists started looking more closely at other potential teratogens, such as alcohol. Fetal Alcohol Syndrome was officially recognized in 1973. Even a small amount of alcohol can take a toll on prenatal development (especially on the brain), as evidenced by the fact that alcohol is the leading teratogenic cause of mild mental retardation. Teratogens that influence the brain, by the way, are called behavioral teratogens. The impact a teratogen has on the developing human depends upon three key factors: genetic vulnerability, the timing of the exposure, and the amount of the exposure. The embryo or fetusʼs genes may make them more vulnerable to the effects of a teratogen. Take alcohol, for example. Some of us metabolize alcohol more quickly than others, and this is influenced by our genes. An embryo without such genes metabolizes alcohol more slowly, meaning that it stays in his/her system longer and has a more devastating impact on development. So, genetic vulnerability certainly matters, although the best advice for a pregnant woman is to avoid this risk altogether by not drinking during pregnancy. How about the timing of the exposure? Again, letʼs focus on alcohol. Maternal drinking during the embryonic period will impact the development of facial features and the brain. In fact, children with FAS (Fetal Alcohol Syndrome) have unique facial features because of this. But, if a mother drinks during the fetal period only, the child may be born with typical facial features but have significant brain damage nevertheless. The amount of the teratogen the developing human was exposed to plays an important role as well. With alcohol, sustained heavy drinking results in FAS, whereas light or moderate drinking may have a lesser impact (although that impact – usually mental retardation – is still quite significant). Some substances do not become teratogenic at all until they reach a certain dosage, something referred P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 2, p. 6 to as a threshold effect. Take vitamin A, which is healthy in small doses but can result in extreme birth defects if taken in large doses. Accutane is a medication for acne and itʼs basically a megadose of vitamin A, which is why many doctors require women on Accutane to be on birth control at the same time. Even if the beginning of life involves complications, thatʼs not the end of the story. With low birthweight babies and those exposed to teratogens, we still have all of the years ahead for a positive environment and responsive parenting to make a difference. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 3, p. 1 EPISODE 3.1 – THE FIRST TWO YEARS: BIOLOGICAL DEVELOPMENT The pace of growth during the first two years of life is phenomenal. We will focus on physical growth in this chapter, with a special emphasis on brain development. Remember how prenatal development is cephalocaudal? The brain is the priority, right? In infancy, the priority of the brain continues with head-sparing. Fat nourishes the brain first. So, even if a child eats less than normal (maybe because of teething pain), stored fat is devoted to brain development first. As a result, brain weight triples from birth until age two! All that nourishment is put to good use because the brain is going through an amazing growth spurt. Body Changes: Brain Development Brain development in infancy occurs at a rapid pace. Neurons, the basic communication cells of the brain, become connected into a massive web of neural networks. The connections between neurons are called synapses. Actually, neurons donʼt touch each other. The axon of the sending neuron gets really close the dendrites of the receiving neuron, but the synapse itself is the little gap between the two. Neurons communicate by passing neurotransmitters back and forth. Neurotransmitters are chemical messages that have specific functions. For example, acetylcholine is a neurotransmitter that enables our bodies to move. Endorphins are neurotransmitters that work as the bodyʼs natural painkillers (and, by the way, are 100 times stronger than morphine!). There are around 100 different substances that function as neurotransmitters, and they are released by the sending neuronʼs axon into the synapse, to be picked up by the dendrite on the receiving neuron. You now know how important synapse growth is for infant brain development, but such growth occurs in two different ways. Some growth is programmed to happen, given adequate environmental stimuli. Our brain “expects” that we will hear things, for example, and such auditory stimulation sets brain development in motion that will aid with language learning. This type of synaptic growth comes from typical, everyday experiences that almost all infants have. It helps us develop normative brain functions. Our brain also responds and grows synapses from our widely varying experiences that often help us develop specific and sometimes unique functions. For example, my years of training in piano helped develop synapses that control motor movements of my fingers, which now helps me type like the wind. We build up loads of synapses during infancy - more than we need, in fact. Now, you would think that itʼs best to have as many synapses as possible, right? Surprisingly, thatʼs not true. The loss of synapses is actually adaptive, if the child is otherwise receiving adequate attention and stimulation. Consider the analogy of a houseplant. When some of the leaves turn brown, that means theyʼre dead and itʼs best to prune them off. Otherwise, if you leave the dead leaves on the plant, the water and sunlight is at least somewhat wasted. Prune off the dead leaves, and the sun and water are focused entirely on the most important parts of the plant – the leaves that are healthy and thriving. Itʼs a similar thing in the brain: We make lots of synapses, but we donʼt end up using them all equally. The rarely-used synapses are like dead leaves on a plant. At around age 2, the brain goes through a pruning process. Unnecessary synapses are pruned so the brainʼs energy can focus on the most important synapses. This allows our brain to become a finely tuned information processing machine. A lack of pruning may lead to information processing difficulties. In fact, an intellectual disability called Fragile-X is thought to stem in part from an under-pruned brain. The cortex is the outermost layer of the brain, 4-6 layers of tissue where neurons connect. Some parts of the cortex are specialized for certain tasks, like vision and hearing. The majority of the cortex contains neurons that help the various specialized areas communicate. Itʼs like a network of information superhighways in the brain. The cortex develops from back to front, with the maturity of the frontal lobes taking the longest to complete. The very front of the frontal lobes – the prefrontal cortex – helps us regulate our emotions, plan ahead, control our impulses, pay attention, and solve complex tasks. It develops gradually from infancy through adolescence and young adulthood. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 3, p. 2 By the way, while weʼre talking about the cortex and its functions, I wonder if you have ever heard that we use only 10% of our brains. If so, let me clarify. This is not true. Itʼs a myth often spread by self-help authors who want to convince you that you have massive amounts of untapped potential, brain matter just sitting around waiting to be used. Thatʼs not accurate. Yes, there are certain areas highly specialized for one task or another, but those areas have to link up and communicate with other areas of the brain. At any given moment, numerous areas in our brain and active and are quickly sending messages back and forth, across the two hemisphere, from lobe to lobe, and in between the cortex and lower-level brain structures. Our brains are buzzing with activity. There is no evidence that 90% of it is just sitting there empty. If youʼve ever known a stroke victim, think about how it sometimes just takes damage to only one tiny part of the brain for us to see major deficits in the personʼs functioning. Now, if the question is whether we reach our intellectual potential, thatʼs a different story. Could we make more synapses? Yes. Absolutely. Research suggests that we are making new synapses continually, but those synapses are adding up within brain regions that have already been active. So yes, we can create new connections among our neurons at any age, but brain plasticity is still the greatest in infancy and decreases gradually with age. In other words, our brains are still plastic in older adulthood, just much less plastic than in infancy. Infancy is a sensitive period for brain development, then, and the shocking story of Romanian orphans communicates this better than any other story I know. Without adequate stimulation, these orphansʼ early years of brain development were atypical. When we donʼt get the typical interaction with caregivers, the impact is felt in the brain. Physical body growth not affected as much (catch-up growth occurs), but brain affected greatly. Emotional problems. Orphanages may take care of the childʼs physical needs, but they may not realize how the physical brain suffers from the lack of emotional interaction. This brain “damage” can last a lifetime and leave the individual more vulnerable to stressful life events. Motor and Perceptual Development Where are you listening to this podcast? Did you turn your computer on, go the website, and click play? Or are you listening in your car on your iPod while you drive to work? You probably didnʼt think much about the highly coordinated series of actions required for you to get to this point. We take for granted our ability to tell our body what to do. If you need something, you just reach out a grab it, right? Well before you can remember, you had to repeatedly practice moving your hands in just the right directions, using your sense of sight to help you, before you would wrap your fingers around the object. You had to practice this over and over again, but, thankfully, you were naturally curious and highly motivated to do so – probably because you really wanted to stick that teething ring or that rattle in your mouth! We begin life with a set of reflexes that get us started moving our bodies. Reflexes are inborn and automatic behaviors in response to certain particular stimuli. When you touch an infantʼs mouth with an object, for example, she opens her mouth and begins sucking. You didnʼt have to teach her this. If you touch your finger to the palm of an infant, he grips your finger tightly. Again, no teaching required. It is adaptive that infants start with reflexes, though, because they often promote behavior that aids survival. Automatically moving the mouth to suck and swallow allows the infant to be nourished by breast milk or formula. Eventually, infants gain voluntary control over these reflexes. You can see this development by tracking how long it takes to feed an infant. It can take quite a long time at first because the infant is struggling to control his reflexes. But, by six months or so, feeding is a breeze because the infant is much more skilled at controlling the movements of his lips, mouth, and tongue. Itʼs a similar experience with grasping at objects using the palmar grasp. The grasp of a newborn may feel quite strong, but the infant doesnʼt have much control over her hand and finger movements until much later in infancy. Coordinated movements involving large muscles, like legs and arms, are gross motor skills, and coordinated movements involving smaller muscles, like the mouth and fingers, are fine motor skills. But we wouldnʼt be able to grasp very well without our senses and perceptions. Senses bring information into the body, and perception occurs once the brain gets involved and helps us interpret the experience. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 3, p. 3 That rattle the infant wants to grasp is an object she must first notice through the sense of vision, but she must perceive the objectʼs distance to know how far to reach her hand out in order to get it. Or, consider another example. A baby hears a voice and smiles. The sense of hearing allowed that information to enter the brain, but the brain is needed to perceive the sound and realize that itʼs momʼs voice. Perception allows the infant to organize and interpret sensory information. The perceptual skills that infants master early in life permit them to make cognitive discoveries about their world, which you will hear more about in the next episode. Surviving in Good Health We are lucky to live during a time in history when death in infancy and childhood is relatively rare. Diseases that once routinely took the lives of infants and children have now been largely conquered through immunizations. The data clearly show us that immunizations save lives. See Table 3.3 in the text for a detailed list of immunizations. Note that each has a risk of side effects, but those side effects are rare and well worth the risk when you consider the alternative. You may have heard media reports of parents concerned that certain vaccines cause brain-related problems like autism. Fear of autism, in fact, has led some parents to skip certain vaccines entirely, like the MMR vaccine. They do this in the hopes of lowering their childʼs risk of developing autism, although there is no empirical evidence to suggest a link between vaccines and autism. In fact, parents who skip certain vaccines increase the risk that their child will become very ill or will die from a disease they are no longer protected against – like measles. Also children who have not been properly vaccinated may carry and spread diseases to other children, perhaps an infant who is too young to have been immunized, or a child who is too ill to be vaccinated. The risks of skipping vaccinations (suffering severe brain damage or death) are much higher than the vaccinesʼ well-researched side-effects. Again, check out the side effects listed in Table 3.3 in Chapter 3 of the text for more information. Nutrition is also very important for infant health. Regarding diet, the most convenient way for the caregiver to provide the infant with the proper balance of nutrients is through breastfeeding. Breast milk is clearly correlated with improved physical health. When it comes to intelligence, though, the findings are mixed. Some studies show a slight IQ benefit for breastfed babies (e.g., 10 IQ points), where others studies show no difference at all. The research on emotional development shows no difference either, suggesting that breast- and bottle-fed infants are equally likely to bond with their caregivers. However, there could be some collateral learning that goes on with breastfeeding, because breast milk is a actually a mild sedative that leaves the infant feeling nice and relaxed. That brings us to the end of this episode on physical development during infancy. We will turn next to the infantʼs cognitive development. EPISODE 3.2 – THE FIRST TWO YEARS: COGNITIVE DEVELOPMENT Why do infants love to throw things off their highchair during meals? Why canʼt we remember anything that happened during the first two years of our life? How are infants able to absorb language so quickly, when it takes adults years of difficult practice to learn a new language? These and other interesting questions will be addressed in this episode. Infant Cognition Jean Piaget is arguably the most important psychologist in the history of developmental psychology. We are lucky Piaget chose to apply his intellectual skills to the study of children because his theory is still being actively researched by many scientists today. Piaget suggested that the way infants and children think is very different from the way that adolescents and adults think. His goal was to document these differences in thought across the infancy and childhood years. Remember assimilation and accommodation? These processes are at work across the lifespan as we encounter new experiences. Obviously, infants have many new experiences. They act on the world, and P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 3, p. 4 then they notice what happens in response. They explore the world using their senses and their motor skills, so perhaps thatʼs why Piaget referred to this stage as the sensorimotor stage. The first four months of the sensorimotor stage involve primary circular reactions, where the infant is learning how to use her own body. It starts with reflexes like sucking, and then it moves to first acquired adaptations, like when an infant realizes that she has to move her mouth differently if sheʼs sucking on a bottle than if she is being breast-fed. To stick with the sucking example, if the infant learns that she can use the same mouth movements to suck on a new object, then she is assimilating the schema for sucking in response to that new experience. But, if she has to change her sucking method or if she realizes something like momʼs angora sweater is yucky when you try to suck it, then she changes her schema for sucking through accommodation. Stages three and four occur from months 4 to 12 and involve secondary circular reactions. During this time, the infant is learning how to make interesting experiences last longer. They are figuring out how to make things happen. Letʼs consider the development of the art of conversation. At first infants just make noise, especially for the first few months. They are cooing, and it may not seem directed at any particular person. Sometimes they donʼt seem to be trying to communicate anything in particular; theyʼre just trying out the vocal cords. At around four months of age, though, an infant begins to understand that when he makes a noise other people may respond to him. In fact, right around four months of age babies begin to stay quiet while others are talking to them. Theyʼve adjusted their scheme for making noise to incorporate their realization that others will listen and respond, and this is something theyʼve learned through experience. Now their behavior has become more goal oriented: they make noise in the hopes that others will listen and make noise back. Around eight months of age, the infant begins to show the first signs of object permanence. This is when the infant realizes that objects exist even when he canʼt see them. To be able to understand that, the infant has to be able to take a mental picture of things, or what Piaget referred to as mental representations. The classic example is when we have a toy, we show it to the infant, and then we put it underneath a cloth. In early infancy, the infant will not even look for the toy underneath the cloth. He will think that the toy has disappeared. Out of sight means out of mind. But as his ability to make mental representations improves, we will see that he understands object permanence better and better. The development of object permanence occurs gradually, and we know this because of research conducted in recent years. Piaget originally thought that object permanence didnʼt truly develop until about two years of age. His methods for assessing object permanence, though, were a lot more basic than what we can do today thanks to the power of technology, and video recording equipment in particular. Object permanence develops more gradually then Piaget thought. During the last part of the sensorimotor stage, from 12 to 24 months, the infant is in stages five and six of the sensorimotor stage. Tertiary circular reactions are being learned. The baby is in an experimental phase during this time, noticing through trial and error why things happen, and then making decisions to try to make those things happen again in the future. They are also playing around to experiment and see what happens in response to certain behaviors. Itʼs almost as if they start to ask themselves, what else could I do with this? Letʼs say that a child is sitting in her high chair, eating the small pieces of banana her father has cut and put on a plate for her. She gets excited and bangs her hands on the top of the highchair. And, oops, the bananas go rolling off the plate. She is fascinated by this and watches carefully. Itʼs like sheʼs realizing, wow, the bananas moved - what happens if I pick them up and throw them on the floor? What happens if I pick him up and squish them in my hand? Piaget referred to infants in this stage as little scientists because of their experimentation in everyday life. This is the kind of stuff that drives parents and caregivers crazy. The infant never seems to tire of throwing things on the floor just to see what will happen. As the child nears 24 months of age, she begins to think about the consequences of future behaviors, and she may plan out a series of events in advance. Dad may notice that whenever he gets his keys his daughter grabs her coat and walks toward him as if to say, “Iʼm coming with you.” Think about all of the planning this involved. The child notices dad is getting his keys. She realizes this might mean that heʼs about to leave. She doesnʼt want him to leave her. She wants to go with him. So, she P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 3, p. 5 makes a decision to go over and pick up her coat and walk toward her dad as if to say, Iʼm going with you. The infant is able to do some thinking before she acts, although this doesnʼt mean that she will always think before acts! It just means that she is capable of thinking through a series of basic behaviors ahead of time. By the way, being able to do this requires that infants have developed mental representations. You are going to learn a lot more about Piaget in the chapters ahead. His theory was a stage theory, meaning that he believed that cognitive development occurs through distinctly different phases as we grow older. In contrast, information processing theory views cognitive development as very continuous, very gradual, and shaped by brain maturation and experience. Remember what I said about the brain becoming a finely tuned machine? Imagine the synapses that form through experience as helping wire up this machine, the brain. As the brain matures and as we have lots of experiences that help us build synapses, we begin to process information more effectively and efficiently. But it takes time. Lots of time. Information processing theory helps us understand how infants combine information across their senses. For example, the research on walking shows us that the youngest walkers are actually the walkers willing to take the greatest risks. Itʼs as if they donʼt really understand depth well enough to realize they might fall while walking on an uneven surface, for example. Older walkers are more cautious when theyʼre walking on some new and unusual surface. They are capable of considering all of that information at once, and using the information to guide their decisions. Why canʼt we remember anything from the first couple of years of our life? Information processing theory sheds light on this question. Perhaps our brain isnʼt mature enough to be able to create the kind of memories that we can recall later. Obviously, weʼre learning during those first two years of life. But how many of us can honestly say that we remember what that was like? Memories that we can talk about, memories that we can discuss and describe, are called episodic or declarative memories. Most scientists think that we canʼt make these kind of memories until weʼre about two or 2 ½ years old. Thatʼs when our information processing system is capable of making those kinds of memories. But declarative and episodic memories are not the only kind of memories we make. We also remember things weʼve seen, and we can imitate behavior weʼve seen later on. If the infant imitates behavior, that indicates theyʼve learned something. When theyʼre grown up they wonʼt be able to say, “Oh yeah, mom I remember when I was 18 months old watching you talk on the phone, and I remember pretending I was talking on the phone, too.” But we see this learning in the childʼs behavior. Deferred imitation occurs when an infant imitates some behavior that they observed previously. Iʼm not talking about behavior that theyʼre observing right at that moment. Iʼm talking about behavior they may have observed yesterday or the day before. This requires mental representations. This requires that the infant has seen something and is able to make a memory of it. Deferred imitation appears around 1 ½ years of age and itʼs especially likely to occur if the experimental conditions are very similar to the infantʼs real life, and when they are particularly motivated to remember. Remember, it isnʼt that infants never make any memories. Itʼs just that when we think of memories as adults, we imagine the kind of memories we can recall, kind of like telling someone a story of what happened. Those are episodic and declarative memories, and those memories do not appear until two or two and half years. The memories that we form before then are not the kind that we can consciously remember and describe later, even though that learning may be clear from watching the infantʼs behavior in the moment. Language Development Language development is one of the most amazing achievements of the first two years of life. Without cracking a book and studying vocabulary, infants are somehow able to translate strings of sounds into words. All throughout language development, comprehension occurs before production (i.e., infants understand more than they can speak), and research suggests that the skill of careful listening starts during the first months of life. Infants are born with the capacity to notice subtle differences among various sounds in languages; in fact, they can “hear” more than we can as adults. An infant notices the P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 3, p. 6 difference between two types of “da” sounds: one that we have in English (e.g., Dah), and one that exists in the Hindi language – a sound that I canʼt even produce for you. Even if I could make that sound, unless youʼre a native speaker of Hindi, you probably wouldnʼt be able to tell the difference between it and our English “Dah.” But infants can tell the difference, at least for the first nine months of life. As their brains become specialized for their native language, though, they lose the ability to distinguish the sounds of all other languages. It is a matter of efficiency. This can help explain why it seems almost effortless for infants to pick up a new language, while we older folks have to study it very, very carefully. And often, no matter how hard we try, we canʼt fully master those sounds that didnʼt exist in our native language. Second-language accents are very difficult to lose, especially if the second language was learned in adolescence or later. Iʼm going to quickly describe the process of language learning in infancy, and then weʼll discuss the innate and environmental influences on this process. The earliest form of communication that the infant is involved with is cooing and gurgling and crying and making other vocalizations. When we speak to infants, we often use child directed speech, slowing down the pace of our speech and emphasizing certain words with variations in our intonation. The simple, high-pitched, slow nature of child-directed speech is actually very helpful to infants. In-depth analyses even show that parents adjust their childdirected speech gradually as the childʼs language skills improve. Think about it. If we spoke to infants the same way we speak to adults, imagine how hard it would be for them to figure things out. Itʼs like someone walking up to you and speaking in a completely foreign language to you, as though you fully understand that language. Youʼd probably give up and withdraw quickly, right? For infants our use of child directed speech actually helps them begin to figure out language. Itʼs easier to break down long streams of speech into distinct words when more space is put in between the words and when certain words are emphasized. On top of that, itʼs simply more interesting for them to listen to. Somewhere around six months of age infants begin to babble, using vowel and consonant pairings that they repeat over and over again. You know what this is. This is stuff like ba-ba-ba and stuff like that. By the way, babbling before nine months of age sounds very similar whether youʼre listening to an infant in India or in the United States. But after nine months of age, when most infants are starting to lose that easy ability to distinguish all speech sounds, they also began to babble more exclusively in the sounds of their native language only. A trained linguist would be able to tell the difference between a babbling 10 month old in India and one in the United States. The first word comes out of an infantʼs mouth somewhere around 12 months of age, although this is an average. Some babies speak earlier, and some babies speak much later. When a child is using one word to communicate a complete thought we refer to that word as a holophrase. I was babysitting for my friends son when he pointed to the door and simply said, Mama? Iʼm pretty sure he was asking me, when is mommy coming home? And I responded by saying sheʼll be home a little bit later. I knew what he meant. The naming explosion comes next, when the infant begins to learn a bunch of words very quickly. Finally, around the age of two most infants begin to put words together. They start to understand grammar, which helps us communicate meaning when we speak to each other. They begin to demonstrate that they know the right order to put words in. Letʼs say the infant asks the sitter, Mommy go? That probably means, “Did mommy leave?” or “Where did mommy go?” Somehow the infant knows that they have to say mommy first, and go second. They never say, “Go, mommy?” So, in two years most infants move from random vocalizations to short phrases that communicate meaning with proper word ordering. How does this happen so quickly? Good question. There are three basic theories that help us understand the rapid development of language in the first two years of life. The first idea is that infants have to be taught how to speak, and that parents and caregivers take care of this job of teaching language to infants during the first years of life. This is a behaviorist perspective. BF Skinner was a behaviorist who believed that language is just another behavior. Infants make noises, for example, when they are babbling. Parents reinforce their babbling behavior by responding to them, and by responding with great enthusiasm when the babbling starts to P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 3, p. 7 sound like a word. Parents get a lot more excited when the baby is babbling da-da-da then when the baby is babbling ga-ga-ga. The infant notices they get a much bigger reaction when they say da-da-da. Thatʼs reinforcing. They like the attention, so they repeat that behavior. Parents gradually shape their infants speech behavior into words, and then phrases, and then sentences. A second idea about language development is that infants teach themselves because theyʼre born with a lot of innate abilities and skills that help them quickly acquire language. Noam Chomsky is the theorist most closely associated with this idea. In the 1960s when he was in his 30s, Chomsky challenged Skinnerʼs behaviorist theory of language. Chomsky argued that reinforcement isnʼt enough of an explanation for language development. We learn language so quickly, and there is also a universal grammar that we see across all languages. The specifics vary greatly, of course, but languages all have words for objects, and words for actions, and rules for how words must be combined in order to make sense. They suggest thereʼs something about the human brain that allows us to put our ideas together in a similar way regardless of where we happen to have been born, and regardless of what language we happen to have been exposed to. Chomsky proposed that we have a language acquisition device, which really just means that we are born with brains that are particularly well-tuned and well-suited to be able to pick up language quickly. Itʼs like the brain is ready for language; itʼs just ready and waiting to hear noises that it will then translate and compute to understand the native language. A third and final idea about how language develops so quickly has to do more with the social impulses that infants have. This referred to as the social pragmatic approach. The idea is that we are social animals who want to communicate with each other, that we are naturally motivated to try to communicate our ideas. You can see this with infants in the way that they try to participate in a conversation even if they donʼt yet really have the words to do so. Thereʼs a curiosity and a motivation thatʼs just there. Infants pick up a whole lot about language, too, just through intonation and from the contexts, before they can ever really understand the meanings of all those words. Finally the social importance of language and the role that that motivation plays is clear when we see research that shows us that infants learn language more quickly through face-to-face communication, talking with another live human being, than they learn from watching some video or television program. Ultimately, we now know that all three of these explanations play a role in the development of language. We need others around us to reinforce the sounds that we make. But we would never learn so quickly and so thoroughly without having these wonderful brains that are ready and waiting for language. Our social motivation to be able to communicate with other human beings drives us to be very curious and interested in figuring out how to communicate, how to use language. Weʼve covered many cognitive developments in this episode, but those developments occur with and the social and emotional context as well. We discussed that in the next podcast episode. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 4, p. 1 EPISODE 4.1 – THE FIRST TWO YEARS: EMOTIONAL DEVELOPMENT The first couple of weeks of life can be very difficult for new parents for a bunch of completely obvious reasons, including sleep deprivation! But it can also be surprising to fully realize that infants do not arrive pre-programmed with smiles and self-awareness. A phenomenal transition takes place during those first two years of psychosocial development. Emotional Development We are born with the capacity to experience two very simple emotions: pleasure and displeasure. We feel drawn toward pleasant stimuli (like food!), and we are repulsed by unpleasant stimuli (like the painful feeling of gas). We might think we are witnessing our infant experiencing pleasure if we see a smile, but if the smile appears during the first few weeks of the infantʼs life, itʼs probably not a real smile. They just happen to be moving their mouth in a smile-like manner perhaps. A real smile, which is what scientists call a social smile, appears for the first time around 6 weeks of age. Laughter begins around 3 months of age, usually when the infant is very curious about something. Itʼs as if they find their new discoveries about the world to be absolutely delightful. As infants mature, their repertoire of emotions expands. Responsive parents play a role by providing an emotional “mirror” of infantsʼ experiences. Just think of how a parent responds to a fussy baby. They often use words and a tone of voice that identifies the bad mood (“Ohhhh, are you feeling fussy today?”) and then they take actions to help alleviate the problem. The development of anger occurs alongside the development of intentional behavior, around 6 months of age to begin with. Think about it: What makes us angry? When our goals are thwarted in some way. The infant doesnʼt have many goals until she is able to plan ahead and make some decisions on her own. The infantʼs decision might be to pick up the remote control. The parent takes the remote control away from the infant, and the infant starts to scream because her intentional behavior has been impeded. Anger is actually a healthy emotion, even though it can be exhausting for parents. The key thing is that the infant is learning to make plans and direct her own behavior. When her plans are stopped, she gets angry. Sadness in infants is not as common as anger, and thatʼs a good thing. The hormone cortisol is released when an infant is sad, suggesting that the infant is stressed out by the experience. With chronic sadness, the infantʼs brain development may be negatively affected. This sometimes happens among infants of depressed caregivers. The mirroring of emotions that is typical of the bond between a responsive caregiver and the infant is largely missing among infants whose parents are depressed, and this has strong effect on the emotional development of the infant. As infants become more accustomed to their primary caregivers, and as they experience cognitive development enough to realize which faces are familiar and which are unfamiliar, they start to show fear in certain situations. This begins around 9 months of age. Imagine what itʼs like for the infant. He sees a new face, but canʼt assimilate it into his “familiar faces” schema. He responds with caution at the very least, and often fear as well. Before 6 months of age, infants prefer being near their caregivers but donʼt get too upset when they meet a stranger or are separated from their mother or father. Sometime between 6-9 months, the infant strongly prefers the caregivers to strangers, and makes this very clear through separation anxiety behaviors – clinging to the caregiver when a stranger is near, crying when the caregiver leaves, and things like that. By the end of the second year of life, the infant becomes more aware of herself as a separate person. This might seem weird to you, but we are not born with the knowledge of ourselves as separate people. Watch a young infant looking into a mirror; they think the reflection in the mirror is just another infant to play with. Around 18 months of age, most infants understand that theyʼre looking at themselves in the mirror. A simple test makes the point clearly. Put a dot of red lipstick on an infantʼs nose, and place him so heʼs facing a mirror. A 12-month old will probably babble and touch the mirror, paying no attention to the red mark on the nose of the individual he presumes is a different child. Do the same thing at 18 months, and the infant will probably laugh and touch his nose. He realizes he has something funny on his P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 4, p. 2 nose! By the way, this procedure is called the mirror test. With this self-awareness comes self-aware emotions like pride, embarrassment, guilt, and shame, as well as the use of first-person pronouns like “I.” Isnʼt it cool how all this stuff develops together? But wait…thereʼs more! The brain is obviously developing during this time as well, as you already know, making all of those synapses. Emotional development is affected by this. The regions of the brain are still pretty permeable and very plastic in infancy. Emotions can easily morph into other emotions. An infant is laughing one second, and the laugh instantly switches into crying. Infants are also more likely to experience connections between sensory stimulation of different sense, an experience called synesthesia. Basically, these brain developments explain why infant emotion is sometimes unpredictable. Infants begin making associations between experiences or people and certain emotions, and this is because of their past experience. If they had a scary time at the doctorʼs office, for example, the neurons that produced that fear helped the infant make an emotional memory. The next time they see that doctor, itʼs likely the infant will feel scared again. Brain development is influenced by stress, as well, in ways that can be seen in infant emotion. We donʼt know exactly how stress influences the brain, but we do know that certain brain structures – like the hypothalamus – tend to grow at a slower pace among infants who have experienced lots of stress. Theories of Infant Psychosocial Development What are the experiences that shape infantsʼ emotions? There are four basic perspectives on that topic – psychoanalytic theory, behaviorism, cognitive theory, and systems theory. Psychoanalytic theory includes both Freud and Erikson. Their theories are similar in many ways, but also quite different in very important respects. Freud focused on how parents help infants manage conflicts stemming from unconscious urges, like the urge to seek pleasure. The first year of life he called the oral stage because pleasure is experienced through the mouth. Notice, itʼs true, how infants are always sticking things in their mouths. Pleasure shifts to the anus in the second stage, according to Freud, as infants learn to gain control over their bowel movements. Freud thought this was all unconscious. Parents have to find the right level of structure by encouraging the infant not to overindulge in the oral stage, and promoting healthy toilet training in the anal stage. If parents are too punishing OR too lenient, Freud said, the result is a mark on the infantʼs personality, a trait that develops related to their unconscious struggle at the time. This mark is referred to by Freud as fixation. Oral fixation? The child may become gullible, “taking in” everything without discriminating. Anal fixation? The child may become a very controlling person, “holding on” excessively. These details are not scientifically testable…and so they havenʼt been supported by any research. We should thank Freud, however, for being among the first of the psychological professionals to suggest that events during infancy can have a long-lasting influence on personality. That broad idea is an important one. Whether the anus plays a key role? Probably not. Eriksonʼs psychoanalytic theory, in contrast to Freudʼs, is focused on conscious conflicts, is scientifically testable, and has been tested quite thoroughly. The first two stages of his theory – Trust vs. Mistrust and Autonomy vs. Shame/Doubt – provide the foundation for a lifespan of emotional development. Our first conscious conflict is between trust and mistrust. We struggle to determine whether the world is a good place, whether people can be trusted, whether our needs will be met. Next, as toddlers we face a conflict between autonomy and shame or doubt. The toddlerʼs budding sense of self is apparent as the word “NO!” is heard more frequently. Parents often refer to this as the terrible twoʼs. The infant wants to feel autonomous, to make her own decisions. But, if things donʼt go well, she feels ashamed and doubts her abilities. Erikson believed that the experiences of one stage remain with us and affect all subsequent stages. At the same time, Erikson recognized the possibility for change, and he believed that experiences during subsequent stages could help us resolve problems from challenges experienced during past stages. An infant who learns to mistrust others is likely to have problems with autonomy as well, for example. If things change for that child, perhaps because her parents become more responsive and caring, she can learn to trust others and repair some of the damage from her first year of life. Behaviorism views emotional development as learned behavior shaped by parents and other caregivers. There arenʼt any stages in this theory. Itʼs just the general idea that infants repeat behaviors that theyʼve been rewarded for, and they stop behaviors that they have been punished for. An infant who is given P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 4, p. 3 attention only when he cries may become a child who throws fits in an effort to get more attention. In contrast, an infant whose parents reward her with attention for positive behaviors are reinforcing those behaviors and making it more likely the child will repeat them in the future. Of course, itʼs never that simple, is it? No. In addition, we learn things from observation as well. Why do parents have to tell their kids, “Do as I say, not as I do”? Because parents realize their children have picked up behaviors simply by observing. This is supported by the behaviorist theory called social learning theory. Parents are often the key models for their children, but books, the media, and other children may act as models to imitate as well. An infantʼs thought patterns impact emotional development, an idea supported by cognitive theories. Based on experience, infants develop a set of expectations called a working model. The working model includes thoughts about how others are likely to respond to us. Itʼs like a schema for relationships. The working model influences the way we perceive our relationships. But what is most important is the infantʼs interpretation of early experiences, not necessarily the facts of those early experiences. If experiences change, the working model may change as well. If later as an adult a person learns to reinterpret those early experiences (maybe through therapy or in the context of a healthy romantic relationship), the working model may change. Whatever it is, though, the working model has a significant impact on all of our close relationships throughout the lifespan. Systems Theory Systems theory is always a very broad perspective, looking at how genes and our biology interact with everything that has to do with our environment. Related to the emotional development of the first couple years of life, itʼs interesting to take a systems theory approach to understanding the development of personality and the development of temperament. Temperament is a distinct reactivity style that is largely present at birth and is thought to be strongly influence by genes. You can think of temperament as falling into three basic categories: easy, difficult, and slow-to-warm-up. Easy babies are exactly like they sound. Theyʼre easy. They get along fairly well. They might get upset, but they get over it quickly. These kind of babies have regular schedules, and they tend to have a pretty sunny disposition. Itʼs different raising an easy temperament baby then raising a difficult temperament baby. Babies with difficult temperament are a lot more reactive, a lot more sensitive. They respond more strongly to stimuli, and this could be in a positive or negative way. Itʼs really more notable when weʼre talking about the negative reactions. Difficult temperament babies are more irritable. They are more easily overly stimulated. They tend not to have regular schedules, and this could make such a child more difficult to raise. A slow-to-warm-up baby is a bit reserved. They hang back, a little shy. They like to check the situation out first before they decide how to act. So parents of slow-to-warm-up children wouldnʼt want to push them into some brand new day care setting without giving that child a lot of chance to get used to the situation. Those are the three main types of temperament. Also, there are a portion of infants who are hard to classify. They donʼt really fit into any of these particular categories. Parents are very familiar with temperament and itʼs really interesting if you take a look at parents who have had only one child and compare them to parents who have had two or three or more children. Parents who only have one child tend to think they have more control over their childʼs personality development, but once they have the second child and often times notice how different the infants were, even from the earliest moments of life, it can really be an awakening moment of understanding the influence of genes. Even though genes are obviously very important, I donʼt want you to get the mistaken impression that itʼs all about genes. Temperament is not all about genes. It starts out with genes but temperament is also influence by the experiences that the infant has. Temperament and personality are sometimes mixed up or thought to be the same thing. In the past, we typically thought of temperament as more the genetically influence characteristics that are there that you can see very early in life and that personality comes more from experience and learning. Systems theory teach us, though, not to think about things as being in such separate categories. Temperament with its genetic influences obviously influences our personality development, but our personality development is also going to be linked to some of these genetic basic qualities that we have been predisposed to. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 4, p. 4 One way to understand personality is by looking at the Big Five personality characteristics. These are some of the most fundamental characteristics that have been noted in research across many different cultures and many different language groups, and across time. An acronym to remember the Big Five is OCEAN – O…C…E…A…N. Openness, which has to do with our interest in trying new things. C…conscientiousness, which deals with being orderly and discipline. E...extroversion, that has to do with how outgoing a person is, how assertive, how energetic. A…agreeableness. Agreeableness is a quality which has to do with how soft-hearted and warm and genuine a person is. And “N” for neuroticism. Neuroticism has to do with negative emotions and a personʼs tendency to feel very anxious and overwhelmed. The Big Five personality characteristics are not directly tied to temperament but you can imagine possible links. A child with a difficult temperament may be especially prone to becoming an adult with high levels of neuroticism. A child with a slow-to-warm-up temperament could be particularly likely to develop low levels of extroversion, meaning they will be more reserved and more quiet. Itʼs clear that the environment plays a role in the development of personality even though we may have these temperamental beginnings that influence us as well. This is clear when you look at some interesting research lately conducted showing us there are actually state-to-state differences in the Big Five characteristics. Where we grow up has an impact on our personality. But how changeable is our temperament or personality? It depends on when weʼre looking at the lifespan. I mean, if weʼre looking at the first few years of life, for example, there could be a lot of change. Temperament shows the greatest stability, meaning the least change from age 3 onward. It also depends on which temperament we start out with. Fearful infants are more likely to change over time and become less fearful. Exuberant and outgoing infants are least likely to change over time. Parents can have, and do have, a strong impact. Most parents will tell you they had to take a different approach to some of their children based upon the childʼs temperament and personality. There are two types of parenting that are often very interesting to look at in how they can impact a childʼs development – proximal parenting and distal parenting. Cultural context influences which type of parenting is important. Basically, parents tend to raise their children with an emphasis on characteristics that are most helpful toward thriving in that particular culture. Proximal parenting involves a lot of contact, a lot of physical contact between the infant and the caregiver. In these kinds of societies where proximal parenting is common, mothers may not put their infant down much at all and thereʼs not as much face-to-face contact. This kind of parenting tends to encourage obedience, but it tends to result in lower levels of self-awareness. These are good characteristics to be developing if you are growing up in a collectivist society. Distal parenting, on the other hand, which involves more face-to-face conversation and more time where the infant is separate from the parents, even if itʼs just the infantʼs across the room playing with something different. That kind of parenting helps promote self-awareness, but tends to result in lower levels of obedience among the children that are raised. And this is adaptive for infants raised in more individualistic societies. Parents behavior is influence by culture and by values and infants developed different strengths and weaknesses as a result, but the infantʼs biological tendencies are still there and are still important and still interact with the parenting they receive. For example, if you think about crosscultural differences, being raised in a collectivistic society, if a child has a naturally exuberant and independent kind of temperament, then that child is probably going to be a little bit more difficult to parent in a proximal manner. Similarly, in societies where distal parenting is emphasize, like here in the United States, a child who is more reserved and shy and perhaps even clingy, may stand out as a more difficult child to raise here than in a collectivistic society. Again, the point is itʼs never environment by itself, and itʼs never genes by itself. Thatʼs the systems theory perspective. Environment and genes are constantly influencing each other. Weʼve talked a lot about the infant in this episode on psychosocial development. In the next episode on psychosocial development, weʼll move out a little more broadly to consider important relationships in the infantsʼ lives having to do with caregivers, and how those caregivers interact and influence the development of the infant. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 4, p. 5 EPISODE 4.2 – THE FIRST TWO YEARS: SOCIAL BONDS An infant goes from expressing pleasure and displeasure to being able to experience embarrassment and pride by the end of their infant years. They also develop from being a being that doesnʼt really understand that theyʼre separate from others to a toddler who can recognize him or herself in the mirror. These developments, which we talked about in the last episode, are all influenced greatly by the experiences that the infant has with the important people in his or her life. The Development of Social Bonds Infant temperament is an important aspect of a childʼs development. A child might be difficult in their temperament, easy, or slow-to-warm-up. But its not just the temperament that determines how to a child will turn out. Itʼs also important, too, how well the childʼs temperament is match with an appropriate environment. One that encourages the constructive aspect of the temperament as best as possible. In this way, nature and nurture, again, both interact. An infant with a difficult temperament will likely develop quite differently whether she has responsive parents or harsh parents. Science may eventually show us that parentʼs impact on the expression of infantʼs genes. Weʼre not there yet, but earlier I mentioned that there is research showing that the way rats nurture their rat pups does have an impact on the expression of those pupʼs genes. Some day we may find the same thing is going on with human beings. Whenever the childʼs temperament is well-matched by an environment that encourages the most constructive elements of that temperament, we refer to that as “goodness of fit.” So itʼs not so much what temperament a child has, itʼs more about how well that childʼs temperament is matched by the environment. Is it a good fit or not? Emotional development occurs in the midst of a lot of interactions, itʼs not just an individual experience. The baby and the caregiver spend a lot of time in face-to-face contact. While weʼre doing this, the parent is often paying very close attention, reading the infantʼs cues, their emotions, their facial expressions, all of their signals. Itʼs like theyʼre really trying to figure the infant out. And the caregiver responds accordingly, mirroring back emotions, and saying back to the infant what we think the infant is experiencing. This is called synchrony, this face-to-face, carefully timed interaction. Infants learn a lot about emotion through synchrony. Think of how it is for the infant, the infant feels an emotion and expresses it. The adult mirrors that emotion back, labels it, and we hope takes action to remedy the situation. This is a lesson in emotion regulation for the infant. Synchrony is so important to the infant that itʼs incredibly upsetting when synchrony gets disrupted. Thereʼs a method in research that shows this very fairly, itʼs called the still-face technique. The still-face technique involves the parent establishing synchrony with their infant, like they do a lot, but then abruptly stopping that synchrony and just looking directly at the infant with a blank face, with a still face. This is very, very disruptive to the infantʼs emotional experience. Most infants get very upset when their caregiver has stopped synchrony. They may cry, or fuss, or look away. The disruption of synchrony is so upsetting that itʼs even more upsetting than if the caregiver leaves the room. In other words, an infant would rather have mom or dad not be in the room than be in the room giving them this still face. Responsiveness of parents, then, is incredibly important. We may not think a whole lot is going on when we share these face-to-face moments with infants, but these moments are crucial for the infantʼs psychosocial development. Thereʼs also good reason to believe that these interactions influence the different development of the brain as well. Moving close to the first year of life, somewhere around 8 or 9 months of age, infants start to show a very strong preference for being with their caregivers. Theyʼre indicating early signs of attachment. Attachment is a strong emotional bond that forms between two people. Our first attachment experience is between us as infants and our caregivers. Attachment is an important foundation of our emotional experiences and itʼs related to many other important outcomes, such as the ability to make friendships and the ability to have healthy romantic relationships later. Attachment, then, is one of the most important concepts that we cover in this class. Developmental psychologists has put a great emphasis on learning about attachments because it has such an important role on our development. Creating a situation where attachment gets triggered involves making a situation a little bit stressful for an infant. Mary Ainsworth developed the strategy that is used most often these days and itʼs called the strange situation. We put infants and their caregivers in a strange but not unsafe environment. Basically itʼs a play room with a bunch of toys, but itʼs a new place the infant never has been to before so they feel a little bit uneasy about being there. A series of separations and reunions with the caregiver and a friendly stranger is part P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 4, p. 6 of the strange situation. The caregiver and the infant start out playing in the room together and scientists who are looking very closely at the infantʼs behavior. Does the infant explore the room freely whenever their caregiver is there with them? Then the series of departures and reunions occur. The stranger comes in the room, itʼs a friendly stranger, but a stranger nonetheless, sits down and starts playing. Then mom gets up and leaves the room. We watch at this point for the infantʼs behavior when mom leaves and the infantʼs behavior in interaction with the stranger. After a short period of time, the caregiver comes back and we watch carefully to see how the infant reacts with the caregiverʼs return. After a few of these interactions, we can get a pretty good idea of which attachment styles the infant best fits within. Securely attached infants explore the room whenever they are first there with their caregiver. They might get upset when the caregiver leaves and they tend to be very happy when the caregiver returns. Itʼs unequivocal. Mom walks in the room and the infant holds up her hands as if to say, “Iʼm really glad to see you mom.” Often times, the infant has gotten upset by the fact that mom left, and we see that with securely attached infants, the caregiver is usually able to quickly sooth the infant and get them feeling okay again. Happily, about 65% of babies in the United States are securely attached to their caregiver. There are a few different types of insecure attachment styles. Insecure/avoidant attachment occurs whenever we see an infant who is acting somewhat indifferent throughout the whole procedure. What I mean is, for example, whenever they come into the play room for the first time, the infant may explore freely, no big deal. The infant though, when the caregiver leaves, may act like they donʼt really care, like they havenʼt even really notice. Some research have shown that infants may have physiological stress while this is happening, but their outward appearance is if theyʼre not too bothered by this. Whenever the caregiver comes back, an insecure avoidant baby often acts no differently. This baby often will not go up to mom and reach for her and will not be upset and seems to act as if nothing weird has happened. Insecure/resistant/ambivalent babies show a different pattern although itʼs still insecure. Itʼs like they want to stay close to mom and are easily upset and frustrated. What happens in the strange situation is when they first arrive in the room, the baby may show a reluctance to leave the caregiverʼs side. They donʼt explore the room fully. When the caregiver leaves, the baby may be upset, but when the caregiver returns, weʼll often see mixed emotions on the part of the infant. The infant may reach for the caregiver, the caregiver picks the infant up and the infant may push away in anger or in frustration. In general, the baby is not well soothed by the caregiver. The most insecure attachment style is the disorganized attachment style. In this case, what we probably have is the infant that is very scared of the caregiver and feels no security whatsoever in the presence of the caregiver. In fact, the caregiver may actually make the infant feel less secure than a stranger. Such infants are cautious and afraid to explore. And whenever the caregiver leaves, the infant may look confused or frightened. When the caregiver returns, the baby may show a wide range of reactions, from showing no emotion at all to freezing in the presence of the caregiverʼs return. Sadly, itʼs often the case that infants with disorganized attachment are victims of abuse. Theyʼve learned that they have no idea what to expect from their parents, that any moment something very scary may happen. Perhaps thatʼs why they are more insecure around their caregiver then they are around other people. With each of these attachment styles, think about how the infantʼs proximity to the caregiver and the infantʼs interest in maintaining contact with the caregiver vary. With securely attached infants we have a baby who feels secure enough in the caregiverʼs presence to be able to explore the room. When the infant explores the room, he or she usually every once in a while checks in back with mom (Is mom over there? Okay, there she is. Alright, she seems happy and relaxed so I guess this is okay). When the caregiver leaves, of course that is a separation thatʼs very distressful to most securely attached infants, but when the caregiver comes back, the infant is happy and relieved and easily soothed. With the insecure/avoidant infant, though, itʼs as if the baby does not count on the parent to be a secure base. They donʼt care to maintain close contact to the caregiver. Insecure/resistant/ambivalent, however, is a different story. Those infants seem to want to stay close to mom. They want to stay close to the caregiver. They seem preoccupied with the caregiver. Itʼs like thereʼs a lot of anxiety in the insecure/resistant/ambivalent profile. And with the disorganized style, like I was saying a moment ago, we have the greatest insecurity, with the caregiver not being a secure base at all and in some cases the caregiver is actually the one that harms the infant. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 4, p. 7 Attachment styles are not necessarily life sentences. Some children may change their attachment status with age. Also, temperament can have an influence on attachment style as well. Difficult temperament babies have a higher rate of insecure attachments to their caregivers. Some of that is probably because of parental behavior, but some of that is also due to what the infant brings to the interaction. That difficult temperament can be very challenging to work with. Parenting can also change. If parenting changes, the attachment status may also change. Remember working models, we just discussed that as one of the cognitive theories for understanding childrenʼs emotional development. Working models change if experience changes. Perhaps parenting was really rocky in the first year of that infantʼs life but things got more stable. Maybe mom and dad got better jobs and stress was reduced in the household and now theyʼre being much more sensitive and responsive to their baby. Itʼs entirely possible that the infantʼs attachment style could change from insecure to secure. The relationship with a caregiver provides the infant with a lot of information about emotion, how to experience them and how to regulate them. You heard this already when we discussed synchrony. But even more than synchrony, infants become very much aware of how their caregivers are reacting to situations. They learn from watching adults in certain situations. This is called social referencing. In situations where the infant in not so sure of how to feel, she will often check in with mom or dad for evidence for how she should feel. In the strange situation, for example, social referencing could be going on. Letʼs say we have a securely attached infant who is a little bit nervous being in this brand new room with these toys and this stranger comes in and that makes things a little more stressful. The baby maybe thinking, “Iʼm not sure how I should be feeling right now.” What do they do? They look at the caregiver. Okay, mom looks relaxed. Mom seems okay with this, so I guess this is a safe situation. There are some interesting gender differences that emerge of how infants tend to use social referencing. Itʼs like they understand that mom provides certain social referencing information and dad may be an expert on other kinds of social referencing information. Moms are looked to more in situations where comfort might be required. For example, if the infant is concerned and is scared and they need some comforting, they tend to socially reference mom more than dad. But dads get more socially reference when itʼs a situation of excitement and fun and something unexpected is about to happen. This does not mean that these differences are genetic. We donʼt know. It could be just the patterns that moms and dads tend to use when they play with their infants kind of teaches infants who is most expert in which kind of emotion. The research does show us that when it comes to parenting, moms tend to do more of the comforting, more of the close-connected, face-to-face type nurturing. Dad, on the other hand, tend to be more involved with more active play, high intensity play, creating exciting moments. How many times have you seen a father toss his infant into the air? I have not seen many mothers do this. And the research bears this out as well. Infants are picking up on our cues and are figuring out who is the best person to watch in what situation. Who is primarily responsible for taking the infant during the day? This could be a very contentious issue, raising questions about priorities and about values, but itʼs also an issue that is far more complex then you usually hear in the media or on a talk show. They may seem the choice on how to care for an infant is a very individual one, bases on the familyʼs interest and economic values. These are important factors to be sure, but we often forget that these decisions are heavily shaped by the larger cultural context as well. For example, in nations where there is more support provided to new parents, in the form of paidtime-off-work for example, we tend to see fewer infants in some kind of non-familial care situation. You may have heard some research suggesting there are some negative outcomes on infants being in day care, especially during infancy. Something that can get very confusing thought is that we can never create the perfect experiment where we can control all of the factors to determine what kind of impact day care has on an infant then and on their development thereafter. The research we are able to conduct on daycare mixes a bunch of factors together. For example, one study in England took a look at infants who were in non-maternal care and found that they developed into less emotionally matured children compared to those that have been cared for predominantly by their mother in their infancy. But those in P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 4, p. 8 non-maternal care were also more likely to be lower income and younger in age. We canʼt separate these factors out so itʼs hard to tell what the impact of day care alone would be. Take for instance the variety of care that is available. It varies dramatically in quality. Family daycare is different from center daycare. Family day care is where an individual, usually in their home, cares for a mix of different children, usually of different ages. And younger children may not get the attention they need. In center daycare, usually children are group by age and thereʼs often a larger staff so children are getting more attention, but quality varies greatly. Some daycare centers are amazingly wise about development, where the professionals working there have taken courses in child development and are doing their best to provide a developmentally appropriate experience for the infants in their care. Others, on the other hand, may be poorly staff, there may not be enough attention paid to each infant, and the focus maybe more on the infantʼs physical needs than on stimulating the infantʼs emotional and cognitive development. High quality daycare centers tend to have a positive impact on a childʼs development, especially on their cognitive and language development. Perhaps because those infants are spending so much time with other infants and thereʼs a lot of interaction going on while theyʼre there. Even though this is the case, the best predictor of the childʼs development, even when theyʼre looking at hours of daycare and quality daycare, the best predictor is the warmth of the mother-infant relationship. But some differences do emerge in the research having to do with the gender of the child. And also with the income level of the family. Regarding emotional adjustment, there tends to be a negative impact of non-maternal care in boys from high socio-economic status homes, but a positive impact on boys from low socioeconomic homes. We donʼt see such a different in socio-economic status and the development of girls. Weʼre not exactly sure why this is the case but this finding has emerge in several different studies. Remember though, we canʼt control for all the other factors so we still canʼt pin it on one or two things. Interestingly, one of the big complaints that you often hear about childcare is that the parents arenʼt spending enough time with the infants. The idea is that presumably, since the parents are working, theyʼre not spending very much time playing with their baby. Studies have shown that working moms spend about 14.5 hours a week playing with their baby. Mothers who donʼt work outside of the home spend about 16 hours per week doing so. Itʼs a difference of about 1.5 hours a week. That surprises a lot of people. What they may not realize is that most working mothers are sacrificing leisure time and time with their husbands to be able to spend more time with their infant. Perhaps thatʼs one of the reasons why the warmth of the mother-infant relationship stands out as the strongest predictor of the infantʼs development. When it comes to infant psychosocial development, and for that case just about any other kind of development, we canʼt boil it down to simple answers. We canʼt point the finger at one single thing that went wrong, or the one thing that was right that led the child to develop in a healthy manner. Itʼs just not that simple. Genes, culture, parenting…it all has an influence and each of those factors influences all the other factors as well. The foundation for emotional and social development is created in infancy, but as you would expect in a lifespan development class, itʼs definitely not the end of the story. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 5, p. 1 EPISODE 5.1 – EARLY CHILDHOOD: PHYSICAL DEVELOPMENT In early childhood, ages two through six, children look much less like infants and more like little boys and girls. This is thanks in part to the combination of growth in height and change in proportion. Many parents are worried that their children are too thin during the early childhood years. But as long as there isn't some kind of medical deficiency, most children at this age are naturally thin and that's okay. Eating and Growing Parents also worry about their children's eating habits. I know a mother whose daughter would eat only refried beans in a certain colored bowl for a long period of time during early childhood. It was such a battle to get her to eat anything else. It's actually quite common for children ages 2 to 6 to have a lot of “just right” preferences: they may insist on eating only certain kinds of foods, will only eat if their food is on a certain color plates, and other kinds of really picky preferences. Most kids will outgrow this so it's usually not anything to be worried about. A potential problem worthy of attention, though, is undernutrition. Are our children getting the healthy balance of nutrients that are recommended? Children need fewer calories in early childhood than they needed in infancy, but they still need essential nutrients. We may think that giving our children fortified cereal will take care of everything, but that is not the case. First of all, that cereal is usually chock full of sugar, and we don't know if it contains all of the vitamins that a child needs for healthy development. We don't even know all that there is to know about nutrition yet, so, just because the cereal is enriched, that doesn't mean it contains all of the nutrients that are critical for child health. The best plan is to encourage a well-balanced diet. Of course, this can be very challenging if the child has their “just right” demands. As long as we can find something healthy that the child will eat, though, that's better than relying on fortified cereal to do the job. It's also better than relying on fast food, which is unfortunately very common. It's especially common in low socioeconomic status families where obesity is a growing problem. In fact, some experts predict that current generations of young children may not live as long as their parents because of the increases in heart disease and diabetes that stem from a high-fat diet. Children have amazing energy during this phase of development. They love to practice their motor skills again and again, usually through play. Gross motor skills are developed quite well during these years, as children run around and use their larger muscle groups to play. By the age of three or four, children have become much better at handling the movement of their bodies. Just compare the toddler–appropriately named for his hearing, precarious walking abilities–to the preschool child, and you will notice how much more confident the movements of the older child seem. Fine motor skills, on the other hand, take longer to develop and require more patience and control of the smaller muscles, like those of the fingers. But they're getting much better. Just compare how a toddler and preschooler approach holding a paintbrush: the toddler grips it in his fist, while the preschooler holds it more like a writing utensil. The development of fine motor skills is also apparent in the variety of crayons available to small children: crayons for the youngest children are much larger and wider than crayons for older children. This is due to the fact that younger children have a hard time getting a grip on those skinny little crayons. The physical development of children can be hampered by environment hazards like air pollution, secondhand smoke, pesticides, and other dangers. We need a lot more research in this area. Currently, one of the best understood hazards for children is lead. Lead is correlated negatively with intelligence and positively with behavior problems. In other words children who are exposed to lead tend to have lower intelligence scores and higher levels of problem behaviors. At high levels of lead exposure, it can even cause mental retardation or death. There are things that P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 5, p. 2 parents can do to protect their children from lead, though. Calcium reduces lead levels, so making sure the child has enough calcium is one tip. Parents should also take care to try to reduce the amount of lead the child is exposed to by removing lead paint and checking for products that they have in the home, including toys, that may contain lead. Brain development Many of the brain developments of infancy continue in early childhood, as children continue to form new synapses between neurons. Synaptic pruning continues as well, as unused synapses are removed so that the neurons can return to an unassigned state. These changes in the brain are accompanied by increases in attention, memory, coordination, and more. The frontal lobe is the location of much of the spring growth. One of the tasks of the frontal lobe is to inhibit impulsivity. Growth in this area is evident when you compare the emotional regulation skills of the two-year-old and a five-year-old. The former is far more likely than the latter to throw an all-out temper tantrum. This is because, from age 2 to age 5, the frontal cortex becomes more mature and can direct the functioning of the emotional regions of the brain. Incidentally, this part of the frontal cortex does not reach complete maturity until the early adult years, which also helps explain why we are better at handling emotions and our 30s than we were as teenagers. Children's brains are getting faster, more coordinated, and better regulated. There's still a long way to go, but it's clear that preschoolers have made great strides. Myelination gradually increases during these years. The axons of our neurons are coated in myelin and that insures that messages are sent more quickly and efficiently between our neurons. This is so essential to our functioning. If you have ever seen the movie Lorenzo's oil, you know how important myelination is. Lorenzo is a child who suffered from a degenerative disorder where myelination is stripped from the neurons. Eventually, this condition results in paralysis and death if not treated. The movie focused on one father's efforts to find a cure, and although the substance he helped discover has shown mixed results in the research, it did seem to slow the progress of Lorenzo's disease. He was paralyzed and could not talk, but he communicated by wiggling his fingers. Sadly, Lorenzo died in May of 2008 at the age of 30, but he lived 20 years longer than doctors predicted. So we should be very thankful if we are lucky enough to have myelin that is developing properly. Our left and right hemisphere are becoming better coordinated in early childhood, thanks to the development of the corpus callosum. The corpus callosum is a massive body of neurons that connects the two hemispheres and allows them to communicate. Our hemispheres tend to specialize in certain functions. The left hemisphere specializes in the movement of the right side of her body, for example, and also specializes in noticing details and helping us produce language. It doesn't mean that the right hemisphere is incapable of doing these things. But it means that certain areas of our brain are really good at performing certain functions and tend to do them rapidly. It's a myth that a person could be right brained or left brained. We are whole brained, thanks to the corpus callosum. We don't even notice any kind of lag between our left and right hemispheres communicating because of the corpus callosum, and it is developing rapidly during early childhood. The brain is becoming better regulated, thanks to the development of the prefrontal cortex. This part of the brain helps focus our attention and checks our impulses. Now, it's developing in early childhood but is far from mature. A four-year-old can pay attention longer then a four-month old, but a 10-year-old can pay attention much longer than a four-year-old. The development of the prefrontal cortex is very gradual, but the maturation that occurs during the early childhood years allows children to manage their emotions better and have fewer temper tantrums, and helps them be able to shift their attention from one task to another. But again, they have a long way to go in developing their attention in the years ahead. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 5, p. 3 The prefrontal cortex is challenged by the activity of the emotional area of the brain. The amygdala is the brain structure that processes gut level emotions, especially fear. When it's very active, especially in early childhood, it overwhelms the functioning of the prefrontal cortex. This means that it's very hard for children at this age to regulate their emotions; they feel something and they express it. How often do you express everything you feel? Well, once we are about 25 years old or so, scientists think that our prefrontal cortex has matured. So we get much better at regulating our emotions. Imagine how far the preschool child has to go. Another structure that works with the amygdala is the hippocampus, which helps process memories for storage. Together with the amygdala, hippocampus helps the child figure out when to be afraid and when to feel relaxed. When the child is afraid, just like when you or I are afraid, a structure called the hypothalamus alerts the hormonal system to release stress hormones. If the child is exposed to a lot of very scary experiences early in life, their brains could be regularly inundated with stress hormones, which could affect the development of their brain. EPISODE 5.2 – EARLY CHILDHOOD: COGNITIVE DEVELOPMENT Thinking During Early Childhood The mind of the preschool child is a magical place. They are able to make mental representations, and they understand things exist even when they can't be seen, thanks to object permanence. They're getting so good with words and mental representations and objects, that they can pretend that one object is a symbol for something else. In pretend play, a plastic banana could suddenly become a telephone. The child's friend could suddenly become the teacher as they prepare to play school. Symbolic thinking has advanced. But the preschool child also shows clear limitations in their thought processes. Children tend to focus on one aspect of an object, person, or situation. This is called centration. They often center their thinking on their own perspective, a phenomenon called egocentrism. This isn't the kind of selfishness that we think of when we call an adult egocentric. Rather, it's a cognitive limitation, an inability to be able to take the perspective of another person. This can explain why preschool children are not so great at hide-and-seek. They have their eyes covered and they're bent over. And so, since they can't see you, they think you can see them, and they don't realize that half of their body is hanging out there in plain sight. The appearance of things can also throw them off. Children might become confused after meeting a girl with short hair, because in their mind only boys have short hair. Static reasoning is a limitation where the preschooler believes that things always change all at once. Irreversibility is yet another limitation, where the child has difficulty working backwards after a series of behaviors have occurred. Let's say that Dad put a tomato on their hamburger, the child complains, and Dad says, “OK. Well, I'll just take it off.” That might not be enough for the child, because they have a hard time understanding that now it's just a hamburger once the tomato has been taken off. They have difficulty understanding that you can reverse that action and return the burger to its original state. In early childhood, they have trouble understanding logical operations, like conservation. Conservation is kind of a funny word, I think, but in this context it means the ability to understand that the amount of the substance hasn't changed just because its appearance has changed. If we take two clay balls of the same size, and I smash one in front of you, you know that I haven't taken away any of the clay. I just changed its appearance and shape. Preschoolers have a hard time with this. They think if the appearances changed, this means that the amount of the substance has changed as well. The classic example involves showing a preschool child two glasses of water that clearly have the same amount in them. Then, take one of his glasses and pour it into a taller, skinnier class. Now, the appearance has changed. The water level is higher in the skinnier and taller glass, right? But you and I know it's still the same amount of fluid. The preschool child has difficulty with this, in part because they get thrown off by the appearance. They usually think that there's more in the taller skinny glass, even though they watched you pour P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 5, p. 4 that original same-sized glass of water into the tall skinny glass. See, they're having trouble with reversibility, too. Finally, preschool children tend to project their egocentrism on to inanimate objects and assume that those objects operate like human beings do. The child may ask, “Why are the clouds crying?” when it's raining, assuming the clouds operate like human beings. This is called animism. Anyone who has ever helped a child work a puzzle has experienced the social context of their learning and cognitive development. A child can complete a much more challenging puzzle with the help of someone older and wiser than they can complete by themselves. A little bit of structure and a little bit of hinting can go a long way. This is what Vigotsky noted, that social interaction facilitates learning. Children are the apprentices of adults and others who are older or wiser than them. It's like they are apprentices in thinking. We structure the learning environment in certain ways to help children figure things out. Scaffolding occurs when we structure the learning environment so that the child is operating just outside of the level of skill they could do by themselves. This is called the zone of proximal development, that range of task that they can complete with the help of others. To help with this social interaction,Vygotsky believed language was an important tool. You can see this happening with children as they begin to move out of their zone of proximal development, and into a range of being able to do it by themselves. Private speech can often be heard. This is when the child is talking to him or herself, reminding themselves of what they need to do next in order to complete a task. In this way, language serves a role as a social mediation tool, connecting the past experience they've had in the social context with their future ability to do it by themselves. Children develop their own theories about the way things work. They're trying to figure out what's going on. How often do you hear a child between the ages of two and six asked the question, “Why?” They want to learn more. They're searching for explanations. This is called the theory theory. Eventually, they begin to understand how other people's minds work. Remember, with egocentrism, they are incapable of taking the perspective of others. But, as they observe events in their lives and as they develop their cognitive skills, they begin to see that others have their own thought processes, and that others' thoughts might be different from their own. This can be really weird to understand from our perspective as adults, because of course we know that other people have minds and think different things than we think. This was not obvious to us until probably around 4 1/2 years or five years of age. Understanding the minds of others and how they operate is called theory of mind. We can test theory of mind by asking children to imagine situations where they know something that someone else doesn't know. For example, imagine that they've just been shown that a box of crayons actually contains M&Ms inside. If you ask a three-year-old what someone else is likely to think is in that crayon box, she will probably say M&Ms. She thinks that because she knows there's M&Ms in the box, that everyone else knows it, too. She hasn't figured out that other people will have a different perspective because they've not yet seen inside the box. Around five years of age, most children come to this realization. In the scenario I described, a five-year-old who already knows there's M&Ms in that crayon box would probably say that someone else think there are crayons in the box, even though he knows that there are actually M&Ms in the box. The maturation of the brain influences this development. Theory of mind is influenced not only by brain development, but by other influences as well. Children who have excellent language skills tend to develop theory of mind earlier. Children who have older siblings tend to develop it earlier as well. Culture also plays a role. In cultures where the perspectives of others are emphasized more greatly than here in the United States, theory of mind occurs a little bit earlier. And, in children with autism, an absence of theory of mind is usually seen. These children may always have difficulty understanding the perspective of others. Language Development Language development continues in the early childhood years, but it's not as critical a period of change as infancy was. Think of early childhood as a sensitive period in language development, a P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 5, p. 5 time when vocabulary rapidly increases and children show that they're learning the grammar of their native language. Fast mapping occurs when children are able to quickly map a new word on to their pre-existing vocabulary. If they know the word horse, then learning what a zebra is may not take very long because they can fast map it. Imagine a network of neurons in the brain related to the vocabulary that the child has learned, and think about how a new word can get connected right into that network very quickly. Furthermore, myelination helps speed the process of being able to make these connections. Chinese children have an advantage when learning the words that represent numbers, because their number system is more logical than ours. They go from 10 to the equivalent of 10-1, to represent what we would call 11. This lets them fast map new numbers rapidly, and may help explain some of their progress over other countries (including the United States) in mathematics scores. The words that children still struggle with in early childhood, though, are comparison words like near and far. And they're beginning to demonstrate their ability to use grammar, although (paradoxically) their grammar skills sometimes show up in the mistakes that they make. Overregularization is when a child incorrectly applies a rule of grammar. We see this when there is some kind of exception to a rule that the child hasn't yet learned, yet their mistake shows us that they've internalized a rule. Imagine a child has just been told that mommy is going to the store. Mommy leads. Then the child may say, “Mommy goed to the store.” Think about what this represents. They know that they want to talk about mom's behavior in the past tense. They know that you add “ed” to the end of a verb to make it past tense. Mom and Dad never say goed; Mom and Dad say “Mommy went to the store.” Overregularization reveals that the child has internalized rules of grammar. They just haven't figured out all the exceptions yet. We live in a nation where it's common for children to grow up with exposure to more than one language, but is this good for their language development? Yes, it can be, especially if their exposure to both languages is fairly even. Sometimes such kids are referred to as balanced bilinguals, meaning that they had equal exposure to their two languages growing up. Research has shown that there are advantages to being bilingual, such as excellent executive control skills, the kind of skills that help the child switch between one way of thinking to a different way of thinking. And, for most bilinguals, if they learn their second language before the age of six, it's processed in the very same area of the brain as their native language. This indicates that the brain is ready and prepared to be capable of learning more than one language at a time. But it can also give us clues as to why it's so difficult to learn a second language after the childhood years. It's more of a cognitive exercise like learning a brand new subject in school. Schooling Experiences Speaking of school, what kind of school is most appropriate for early childhood? There are two main ways of teaching children at this age: child centered programs, and teacher directed programs. Child centered programs are very focused on child development. Teachers often have to take courses in child development before they can work at such programs. Teachers are not passive, but are instead very involved and aware of the different developments going on in the children's lives. For example, there's a lot of emphasis on the theories of Piaget and Vygotsky in a child centered program. You will see teachers scaffolding learning experiences for children. You will see teachers creating centers where children can discover things on their own, like a science area where children are encouraged to mix different substances just to see what would happen. Of course, there's always a strong emphasis on safety, and I can verify that this is true because I've worked at a child centered program. It's great all that you can do to stimulate the child's mind. Montessori schools are also child centered programs, and they focus especially intently on children's curiosity and activities that help the child feel like an independent person, developing a sense of pride in their own work. The Reggio Emilia approach is very similar as well, with an emphasis on creativity again, but with more attention placed on the actual physical space where the child is playing: lots of open space, big glass walls, lots of greenery. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 5, p. 6 In contrast to these child centered programs, teacher directed program are more of what you would expect to see in a typical grade school setting, where students sit quietly and work, and the teacher instructs in the front of the room. These programs are more affordable, partially because they require fewer staff. There is a higher child to teacher ratio in teacher centered programs, because there isn't so much chaos and freewheeling activity that the adults have to supervise, as there often is in a child centered program. Research shows us that child centered programs are more supportive and encouraging of children's development than teacher centered programs. For example, it just isn't developmentally appropriate to expect a child between the ages of two and five to be able to still for a long period of time. You end up spending a lot of time in a teacher centered program just getting the children to sit still, time that could be spent instead encouraging their creativity and sense of pride. Injuries and Maltreatment The curiosity and the motor skills of children between the ages of two and six allow them to do amazing things, but the risk is that children at this age are also at a great risk of having accidents. The number one cause of death in early childhood is accidents. That's why it's best to focus on ways of reducing harm through three levels of prevention: primary, secondary, and tertiary prevention. Primary prevention focuses on changing the conditions in which the child lives in order to reduce the risk of injury in the first place. Secondary prevention is about focusing on children who are already in high risk situations and helping them avoid harm that they face in those conditions. Tertiary prevention is kind of a misnomer, because it's about what you do after accidents have occurred. Tertiary prevention occurs when we try to limit damage after an injury occurs. This can happen whenever we realize after an accident that there's something unsafe about a certain playground, so we go back and we fix the playground to try to prevent any such accidents from happening again in the future. These harm reduction strategies have helped us reduce the number of accidents that young children experience. Unfortunately, some children are harmed within their own homes at the hands of their own parents or caregivers. Child maltreatment refers to any kind of intentional harm that is done to a child under the age of 18, including any kind of avoidable endangerment. If the child is living in a home with an alcoholic parent, and the other parent is aware of this, and that leads to child alone with the alcoholic parent, for example, that is an avoidable endangerment. When a child is directly harmed in a physical, emotional or sexual way, that's referred to as child abuse. But sometimes maltreatment occurs because no one is paying attention and the child's needs are not being met. This is called child neglect, and it can involve caregivers who do not meet a child's needs, like their physical, emotional, or educational needs. It's hard to get an accurate estimate of how much child maltreatment occurs. Not all cases are reported, investigated, and verified. Substantiated maltreatment is maltreatment that's been investigated and verified, but it's estimated that about two thirds of reported cases are never substantiated, and we don't even know how many cases weren't reported to begin with. We also have the problem of the child's awareness of what's going on, because sometimes children don't realize that they're going through maltreatment when it's happening. The responsibility lies on the adults in the scenario to notice the signs of maltreatment. Caregivers and teachers and anyone who works with children must be trained to recognize potential signs, like delays in development, adult themes coming out and pretend play, or injuries that are unusual or difficult to explain. Obviously, child maltreatment can have devastating impacts on the long-term development of a child, not just in their biological development, but also regarding their cognitive and social development as well. If maltreatment has occurred and the child is considered to be at risk of future harm, a decision may be made–a tertiary prevention effort, in fact–to remove the child from the home. The child may be placed in foster care, whether they're being cared for by another family member or by a non-related adult. The tough thing is that most foster children do not find a permanent home right away; the average foster child has about three placements before they are P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 5, p. 7 placed in a permanent home. You can see that the early childhood years are full of possibility, as these little human being are making rapid connections between brain cells, learning more and more about their native language, using their bodies in a more coordinated and skillful way. But, when damage occurs at this time, it can still have a dramatic impact on the rest of the child's life. That's why we must make it a priority as adults to be on the lookout for the welfare of young children. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 6, p. 1 EPISODE 6.1 – EARLY CHILDHOOD: EMOTIONS, PLAY, AND PARENTING I was a preschool teacher once, and let me tell you, it was one of the most rewarding and difficult jobs I've ever had. Children have so much energy at this age and so much confidence. They want to try new things, but at the same time they can still fall apart in an emotional tantrum at the drop of a hat. This is the first of two episodes about psychosocial development in early childhood, and this one will examine emotional development, play, and parenting. Emotional Development Erikson believed that children were struggling with the challenge of initiative versus guilt. They want to try new things, they want to do things well, and they have incredibly high self-esteem. In fact, their self-esteem is unrealistically high. That's okay, though, because this high self-esteem pushes them to be brave enough to try new things. As they get into the middle childhood years, they'll have a better understanding of their true skills and a more realistic self-esteem. The risk during this stage is that the child may try things but not succeed. Maybe they make mistakes. Maybe their parents are impatient and yell at them for being so adventuresome. The outcome could then be guilt and shame. Guilty feelings come from within the child herself, whereas shame comes from the recognition that the child has that they have disappointed others in their social world. Children are learning slowly how to regulate their emotions. Remember, their prefrontal cortex is developing but is still relatively immature. So they are gaining some control over the expression of their emotions, but they don't have complete control yet. I don't know, do any of us ever have complete control over our emotions? Anyway, the motivation behind children's behaviors in regards to expressing their emotions may come from within (intrinsic motivation) or may come from external pressures (extrinsic motivation). At first, the child may not want to cry at preschool because he is worried that the other kids will make fun of him. That's extrinsic motivation. Eventually, we hope that his emotional expression becomes more and more guided by intrinsic, internalized motivation. Think about the role this plays when a child is having fun. Why do the child play? Because she's intrinsically motivated. She enjoys it. She does things because they're fun. It can be a danger if the child is having trouble with emotional regulation. We need to learn how to regulate emotions, but we don't want to overregulate our emotions. Problems with emotional regulation can reflect an early warning sign for future psychopathology. Problems occur when the child regulates too much, and also when the child doesn't regulate enough. Externalizing disorders tend to arise among children who do not regulate their emotions enough. These are children who are prone to lashing out, often in anger. But it's also a problem to hold in emotions too much. This can result in internalizing problems, where there's a lot of fear and the child withdraws as a way of managing his emotions. Externalizing disorders would involve things like conduct disorder. Internalizing disorders would include anxiety and depression and other psychological disorders. Both boys and girls can have both of the kinds of problems, but in general girls tend to internalize and boys tend to externalize. We don't have any specific brain related differences we can point to to explain this difference as of now, but the difference also holds in adulthood. Think about it. Internalizing disorders like depression are much more common among women than among men. Externalizing problems like drug and alcohol abuse or criminality are much more common among men than in women. So it's clear that we need to place a high priority on helping children learn how to regulate their emotions, and this is where caregivers come in. Interestingly, a parent with a difficult temperament child may actually end up having many more opportunities to teach their child to regulate emotions. But, regardless of temperament, parents play an important role in walking their child through the experience of an emotion. Think about that child's amygdala firing full force, and her relatively weak prefrontal cortex is hardly any kind of match. Emotions overwhelm her. She P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 6, p. 2 needs a caregiver to patiently and kindly help talk her through the experience, from identifying the emotion to thinking of ways to handle the situation. Many parents are doing a great job at this, but when there is child abuse or neglect in the home the child is getting the wrong kind of training: they're learning how not to regulate emotions. But a child could have terrific parents and still develop internalizing or externalizing disorders. Parents do not deserve all of the blame when things turn out badly, but parents also do not deserve all of the praise when things turn out well. We always have this child who brings with him his genetic predispositions, and goodness of fit between that temperament and the environment matters greatly. Play What was our job as preschoolers? To play. Play is the work of the child. But play isn't just a way to have fun; play provides loads of opportunities for learning. Take emotional regulation, for example. Sure, children learn about emotional regulation from their parents, but they learned different kinds of emotional regulation skills with their friends in play. They have to figure out how to negotiate, how to interact with someone and make decisions when you are on the same level. Parents usually go along with everything that the child has requested in play. If the child says, “You play the doggie!” The parent says, “Okay.” That isn't always the case with friends. A child's friend may not want to be the doggie this time because she was the doggie last time. Maybe she wants to be the kitty this time. How do you come to a decision when there are two people at the same level of authority? Children begin to face this challenge in the early childhood years, and it's a challenge that will continue to be important to master in the grade school and adolescent years as well. Children have always been motivated to play, although today children watch a lot more television than they used to. What they see on television often comes out in their play, and they pick up on a lot of what they see. Even by the age of six, children begin to show knowledge about sex because of what they've seen on TV. It used to be the case that knowledge about sex in childhood was an indicator of child sexual abuse. It could still be, so concerned caregivers, friends, or neighbors should always look into a suspicious situation. But, it is also the case that children today are likely to have a certain amount of knowledge about sex simply by being exposed to television programs. This doesn't mean that they understand correct things about sex; in fact, their sexual understanding tends to be very confused. When they step away from the television, there are many types of play children may engage in. They may play by themselves, which is called solitary play. They may spend their time watching other kids play, which is referred to as onlooker play. Sometimes children will play in the same room with other children but they're playing with different toys and not directly interacting with each other. This is called parallel play. As they get a little bit older, children engage more in associative play where they interact directly with others. Play becomes more collaborative and is called cooperative play when the children are engaged in an activity in a very reciprocal and mutual way. Let me make sure that this difference between associative play and cooperative play is very clear. Have you ever seen children playing together, watching each other, sharing some of the same toys, but not directly incorporating each others' observations or behaviors into the overall play experience? That's associative play. Contrast that with play where the children are clearly working together on some kind of joint activity, taking turns and incorporating each other's behaviors or statements into the play. That's cooperative play. But it's interesting to note that the research behind these types of play was conducted a long time ago, and more recent research suggests that it's becoming more and more common for children to prefer solitary play. This may be a very Western phenomenon, having to do with our cultural emphasis on individualism. In fact, in some cultures it's quite normal for children to begin sharing and cooperating earlier than we see here in the United States, even at the age of two or three. Remember, development is multicontextual and multicultural. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 6, p. 3 Children like to run around a lot. This is good for developing their motor skills and for allowing them to release some of their boundless energy. Sometimes it may almost look like children are fighting, when they're actually just engaged in rough-and-tumble play. We see this happening all across the world. It's a universal phenomenon that is especially common among boys. look at the children's faces and that will tell you whether they are really fighting or just playing around. You'll see a play face, a smile on the faces of the children as they wrestle and tumble around, if it's rough-and-tumble play. It's like building their own little playground where aggression and activity are okay. Children regulate themselves. Imagine children playing tag. They realize that a child has been "it" too long so they slow down so someone else can get tagged and be "it." Sure, there's always the possibility that a child may take it too far and play too rough. In most cases, children realize when they've hurt someone, they apologize, and they see what they need to do to make amends. If that doesn't happen, it's likely that that child will not be invited into rough-andtumble play as much in the future. We should notice when and if this is happening frequently, because it could be an early warning sign of a child with emotional regulation problems. If we intervene now and try to teach that child some social skills, perhaps it will prevent them from becoming a child who is rejected by the peer group later. Playing pretend is another favorite activity in early childhood. This is called sociodramatic play, because it takes place among friends in a social context and involves acting out certain roles like teacher, baby, and so forth. In this case, it's like they're making their own theater productions that allow them to explore roles and things that they've seen in the world happening around them. They learn about emotions as well, when they pretend to be upset or happy or scared as they play their role. Children are interacting with equals, other children, during sociodramatic play. They have to communicate their ideas persuasively in order to get other children to go along with the story they're telling. Negotiation skills and other social skills are important for this. The stories told in sociodramatic play are really simple when children are two or three years old, but the stories become incredibly complex with elaborate roles and plots and situations as the children develop. There are gender differences to note as well. Boys' sociodramatic play tends to focus on themes of good and evil, whereas girls' sociodramatic play involves more domestic themes (like playing house). Challenges for Parents What's the best way to parent a child? Good question. You can get in pretty heated discussions with people by asking them what they think is the best way to parent a child. Although there have been many attempts to figure out the different ways adults can parent and which of these are most effective, parenting styles vary by historical period and by culture as well. Research conducted before I was born is still used as the primary basis for understanding parenting styles. This research was conducted by Diana Baumrind, who interviewed and observed many preschool children and their parents. Her work uncovered for basic parenting styles. How many of you have heard parents say, “Because I said so!”? You might've been listening to an authoritarian parent. Authoritarian parents rule with an iron fist. They decide what the rules will be, and they enforce them strictly. There is no room for discussion; the child is simply expected to obey. It's good that the child is given some structure and knows what the consequences will be for his or her actions. But the trouble with authoritarian parenting, especially here in United States, is the lack of emotional warmth. The parents clearly love their children, but their interactions with their children are focused mostly on making sure that the rules are enforced. It can make children feel distant from their parents and like their parents don't care. These children tend to grow up to be obedient, but unhappy or even depressed. On the opposite end of the spectrum are permissive parents. They are very warm. They listen to their children and are very responsive to them. The problem is that they don't provide any structure. Anything goes. Children get the sense that they are loved and that they are permitted to express themselves, which is great. But it can be very tough on kids when they are raised without P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 6, p. 4 any structure. The risk is that children with permissive parents may not develop the self-control that's needed to become a mature and fully functioning individual. Permissive parents may also step in to defend their child inappropriately if there's been a problem at school. I'm not talking about simply looking out for your child's best interests. I'm talking about always assuming that the child is right and that others who had different perspectives must be wrong. Imagine that a fight has broken out at school, and the child is identified as the instigator (the one who started it), but the permissive parent simply can't accept that that's possible and defends the child even when the evidence clearly shows he was at fault. See how it would be hard to develop that internal sense of responsibility and self-control if you were raised this way? Authoritative parenting falls somewhere in between authoritarian and permissive parenting. You'll want to keep in mind that it sounds a lot like authoritarian, so do what you have to to distinguish these two terms in your mind. Authoritative parenting involves warmth shown to the child and structure. Children learn that there are rules that need to be followed, but they also learn that it's okay to speak up and ask why. Authoritative parents don't say, “Because I said so.” The parents listen to what the child has to say, but make the decision in the end. This doesn't mean that the children run the show. Not at all. Authoritative parents are very much the authority figure, but they allow for the child to express him or herself. They place a high premium on communication. I had a student once who told me that her parents would require her to write an argumentative essay defending her position when she disagreed with their rule. This was when she was a teenager, but I still think it's a great example of authoritative parenting. They would read her paper and consider her position. Sometimes they were persuaded to change their mind or to bend on a certain rule, but sometimes they stuck to their original decision. In the United States, authoritative parenting tends to be the best for child development. But it's not a guarantee. None of these parenting styles offer guarantees. The child's devleopment also depends on the child's temperament, cultural influences, and interpretations. Neglectful or uninvolved parenting is the fourth style and the worst style for child development. These are parents who are simply checked out. They don't know what is going on in their child's life. They don't set many rules, but they also don't show much warmth. It's as though they really don't care, so you can imagine that this parenting style is not healthy for child development. Being involved with children is the most important thing, even if you're an authoritarian parent who is too harsh, or a permissive parent who is too lenient. Ok, so you know that the neglectful and uninvolved parenting style is the worst, but which style is the best? We discussed how authoritative parenting tends to be the best in the United States, given our culture that emphasizes independence. It's a great idea to emphasize independence in your children when you're raising them in a culture where they are expected to become very independent people. We place a premium on the importance of our children growing up with the idea that they should be permitted to speak their mind. This style may not go over so well in cultures where individualism is not emphasized. Authoritarian parenting tends to result in negative outcomes in the United States, but may not have the same negative impact in other cultures where the parental behaviors are interpreted differently due to the cultural context. A child raised in an Asian culture may interpret their parents' demands as evidence that their parents care. It's not exactly what we would call warmth here in the United States, but we make our interpretations based in part on our cultural context. If you take a systems approach to the issue of parenting, you realize it's very difficult to come to a conclusion that one parenting style is always the best. What is the child's temperament? Let's say we have a boy with an easy temperament who is raised by permissive parents. And let's say he's the kind of child who is very outgoing and kind and likes to please others. His permissive parents may not have a negative impact on his development. Perhaps this boy has already had a predisposition toward high self-control. Imagine a girl raised by the same parents, a girl who is rambunctious and strong-willed. Raised by permissive parents, she may exert her will and get her way again and again and again. She may P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 6, p. 5 become a very selfish, self-centered, and demanding person. Her parents didn't make her that way, but there was a lack of goodness of fit. Consider a very emotionally sensitive child, let's say a boy who needs a lot of reassurance and is fairly quiet, if you pair him with authoritarian parents he may become a very withdrawn and depressed individual. Parenting styles have different impacts depending upon the temperament of the child. Also, parents sometimes change their style over time, or a child's two parents may have two different parenting styles. Parents are challenged these days by figuring out how much media to expose their child to. It's inescapable. Media is everywhere. Were also living in an age where it's important to expose children to technology because it will most certainly play a fundamental role in their lives. So we don't want to keep our kids sheltered away from media entirely, but we also need to be careful and thoughtful about the media they consume, to whatever extent we are capable. Children really like to watch TV, so they will sit there for a long time feeling very content. During the early childhood years, research tells us that children are watching around three hours of television every day. This research was conducted in 2004, though, so the number may even be higher today. We have to remember that children do not have the same cognitive skills that we have, so they may take different things away from media than we do. We may understand that a television program is just pretend, that what we see on the television screen isn't really the way things really are. Why should we expect young children to be able to come to the same conclusions, especially given the fact that they have difficulty at this age with logical thinking and are quite egocentric in their perspective? A finding that has been replicated many times is that watching violent television programs is correlated with an increase in violent behavior among children, and this tells us that media has a considerable impact on children's development. What about educational television? There are some good programs available today, it's true. But there's still the issue of how much time the child spends in the relatively passive mode of watching TV compared to the more interactive experience of talking or playing with another human being. Take language development, for example. Language development is helped more by face-to-face interaction than by a child watching a video or a television program. And emotional regulation is especially dependent upon face-to-face interaction with caregivers. Think about it. The more a family relies on media as entertainment, the fewer hours there are left for face-to-face interaction. So, turn off the TV, turn off the computer, face each other, and get interactive! EPISODE 6.2 - EARLY CHILDHOOD: MORAL AND GENDER DEVELOPMENT Welcome to the second episode on psychosocial development in early childhood. This episode focuses on moral development and gender development. Moral Development What is right and what is wrong? Most parents are very concerned that their children learn about this. Moral development speaks to a person's character, the guidelines that they use to judge their behavior in the behavior of others. There's no doubt that temperament and personality play a role. Early in life, when children are playing, we see evidence of empathy and antipathy. Empathy is the ability to be able to understand what another person is feeling. Empathy is most obvious whenever we realize that someone feels differently right now than we feel. Maybe somebody is really sad. We are not sad, but we feel empathy in that we understand they feel sad. In our brains, mirror neurons help us understand how empathy is at least somewhat hardwired. Mirror neurons fire in response to what other people are doing, and these mirror neurons fire in similar areas where brain activity is going on in the person they're observing. Empathy provide the basis from which prosocial behavior can develop. Prosocial behavior is when we do something nice for somebody else without any payoff. We do something nice just because we want to. On the other hand, antisocial behavior can stem from antipathy. Antisocial behavior is when we behave in a P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 6, p. 6 harmful way toward others, and this can include physical harm or emotional or verbal harm. It can also involve exclusion. Thankfully, across the early childhood years, most children show an increase in prosocial behavior and a decrease in antisocial behavior. But children will have aggressive impulses. The question is how they will handle those aggressive impulses. It also depends on making judgments about when aggression is justified and when it is not. Patterns of aggressive behavior show developmental change for most children. When we are babies, we want what we want. Think of that very immature prefrontal cortex allowing the urges of the limbic system to spill out full force. If the two-year-old takes a toy from another two-year-old, there is likely to be some instrumental aggression. This is aggression directed at someone because you want what they have. This is really normal, and it increases from ages 2 to 6. Instrumental aggression usually isn't something for parents to worry about; it's an indicator of egocentrism more than antisocial tendencies. Reactive aggression usually decreases from ages 2 to 5. It's the kind of aggression where a child hits or yells at another person because they've been hurt in some way, even if it was accidental. Imagine a two-year-old who gets bumped into accidentally by another two-year-old. If in response, he purposefully hits the child back, that's reactive aggression. When I worked in childcare I spent some time in the one and two-year-old room, the toddler room, and you would see instrumental and reactive aggression ping-ponging back and forth. One child hits another because he wants a toy (instrumental aggression), and the other child retaliates by hitting him back (reactive aggression). As children grow older and become more aware of the social world, they may start to use relational aggression, insulting other children or trying to get children to take sides against another child. This can really escalate into the school years and even into adolescence. Bullying aggression is a sign of a problem with emotional regulation. Children who bully often misread the signals of others and they seek out the weaker children to pick on. Interestingly, bullies don't realize how much they are disliked, and it's very important to intervene before the school-age years so that the bullying does not escalate. So, in general, aggression decreases as the child ages, but the aggressive acts that continue into childhood tend to be more severe than those that occur during early childhood years. So, what can we do to try to prevent aggression from escalating? Parenting does play a role. Parents are always trying to figure out the best way to discipline their child, and a common reason is because they want to teach their children right and wrong. It's especially difficult in early childhood because children's poor emotional regulation skills make them likely to blow up at any time. It doesn't matter how strongly and securely attached the child is to her parents, though. What seems to make the biggest difference is the way the parents handle those conflicts. It's best when parents act as emotional coaches in these situations, realizing the children have limited abilities to regulate their own emotions and trying to use that realization to increase their own patience when dealing with their child. It helps when parents explain why certain behaviors are unacceptable. It helps when parents remind children that other people have different viewpoints. “Sam is sad because you took his toy. How would you feel if Sam took your toy? You'd feel sad, right?” Remind the child frequently. They are unlikely to understand everything after just one explanation. And explain these matters before bad behavior occurs, and after bad behavior has occurred. It may seem like scientists are suggesting that parents should go really easy on their kids. That's too simplistic. The research shows us that it's vitally important that parents set rules and follow up consistently on those rules. But we have to consider that the child's mind operates very differently from our own, and that what the child takes away from the experience may be very different from what we intended. Take physical punishment, for example. Spanking often works in the moment, but the research shows us that there are some long-term risks of regular spanking. Those who are spanked as children, and especially those who are spanked frequently, tend to grow up to become more aggressive than other children. It seems as though they've learned that violence is an acceptable way to deal with their frustrations. Of course, it's not just spanking that matters, P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 6, p. 7 though. The child's temperament matters, and other factors like the environment in which they grew up matter as well. But we don't know for sure how the temperament of our child will interact with spanking behavior, so the best advice is to try to avoid spanking if at all possible. There are consequences to other kinds of punishment as well. Some parents use guilt as a method of controlling their children. This is called psychological control. It may seem like a great technique because it doesn't involve any physical punishment, but the risk is that the child's selfesteem will be depleted as a result. Basically, we're trying to make the child feel really bad about what they've done, but not so much in an effort to explain why what they've done is wrong, but more as a way of threatening the child with the idea that their parent will withdraw love. The idea that's communicated to the child is, "You are a bad person, and you won't be loved as much if you keep doing those bad things." Timeout is another popular technique, where the child is removed from some activity for a brief period of time as a way of trying to punish them. This can work reasonably well, especially if parents stick to the rule that timeout should last about 1 min. per year of life, so a four-year-old gets 4 min. of time out but a two-year-old gets 2 min. of timeout. This is really a behaviorist method, because what parents are trying to do is to remove something the child was enjoying as a way of letting them know their behavior was unacceptable. Let's say the child is playing at her childcare center, will not share her toys, and starts a big fight over it. Timeout would involve removing her from that play situation that she was presumably enjoying for a period of time. You have to be careful though, to make sure that you're removing the child from something he or she really likes, otherwise it doesn't function as a punishment. Another technique that shows promise is time in, where the child is removed from the situation in order for the caregiver to patiently and calmly have a conversation about the behavior and what is unacceptable about it. It's really important during these conversations that parents and caregivers remember the child's cognitive limitations, and keep their remarks very focused and straightforward so that the child can understand. Becoming Boys and Girls I wonder if this heading struck you as odd. Becoming boys and girls. Aren't we just born boys and girls? Yes, most of us are born with a clear biological sex, although there are some variations and some children are born with a mix of physical characteristics from both sexes. But that's a different topic for a different class. We are not born with a fully formed sense of gender, though. Gender has to do with social roles and cultural ideals for what's acceptable behavior from boys and girls, and men and women. It's a lot more subjective than biological sex, and it is influenced by the environment. It's very difficult to separate the nature and the nurture of gender development. Clearly, like with everything else in this class, the two interact. Even though we have become a far more open-minded society when it comes to thinking about gender roles, children still tend to develop a very strong sense of gender appropriate behavior during the early childhood years, sometimes even when their own parents have painstakingly tried to keep their upbringing as gender neutral as possible. I remember the daughter of our family friends going through a change around three or four years of age. Before then, in line with her parents' wishes, we tried to give her gender-neutral gifts whenever possible. And she liked them. But by the time she was three or four, her parents told us that all she wanted these days were pink things and other stereotypically feminine things. So, we obliged, and bought her a little dress up kit that year, complete with a princess gown that she loved. How do we understand this gender development during early childhood? Let's talk about what the four main theories have to say about gender. Psychoanalytic theory provides perhaps the most provocative explanation of gender differences and their development. Again, let me remind you that Freud's work was not scientific in today's standards. So keep that in mind as you learn about his ideas. Freud referred to the early childhood years as the phallic period of development, when the pleasurable urges relate to the development of the genitals. He believed that children at this age unconsciously have sexual desires for their opposite sex parent. This is the Oedipus complex for boys and the Electra complex for girls. It's a key time for moral development, Freud believed, P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 6, p. 8 because the child has to learn how to manage these unacceptable urges. As a result, they develop their superego, which Freud believed is the part of the personality that tells us what's right and what's wrong, the lessons we've learned from our parents and from society at large. This relates to gender because, in the process, the child identifies with their same-sex parent as a coping mechanism for dealing with their unconscious sexual desire toward their opposite sex parent. The idea is, “If you can't beat them, join them.” In the girl's unconscious, it goes like this, "If I can't have dad, then I will try to be as much like mom as I can be, so that one day I can get someone who's like my dad." In the boys' unconscious, it's "If I can't have mom, then I will try to be as much like dad as I can be, so that one day I can get someone who's like my mom.” And thus, Freud believed, the development gender roles occurs. Behaviorists took a very different point of view on gender development, which shouldn't surprise you because behaviorists usually take a very different point of view than psychoanalytic theorists do. Behaviorists would say it's all about simple reinforcement or punishment. We tend to reward those behaviors that fall in line with our societal gender norms, and punish those behaviors that fall outside of our gender norms. Imagine how parents react, most parents I should clarify, when their boy wants to try on a dress. It's a freak out moment for many parents. Children pick up on these reactions and learn from them. In the early childhood years, most parents are most concerned about their boys being gender appropriate. Boys get more pressure during this age than girls do. They also get more pressure from their fathers than from their mothers. Early childhood is a very intense time for boys' gender socialization. Social learning theory suggests that children don't even need to be directly rewarded or punished to learn gender appropriate behavior. They pick up quite a lot from simply observing others. Children have lots of role models available to them at this age, from their parents, to their teachers, to the characters in the books that they have been read to them, to the behaviors shown in the movies or cartoons that they watch. There is considerable overlap across some of these theories, and that's the case with behaviorism and cognitive theory. I was just telling you that children are very much aware of how men and women behave in the world around them. One of the reasons why they pay so much attention is because of their cognitive development. They have developed a schema for gender, their gender schema. It's like their all-purpose gender related category, and it helps them quickly pick up gender information going on in their world. But children have a very simplistic understanding of the world, so it makes sense that their understanding of gender is really simplistic as well, really black and white. The difference between cognitive and behavioral theories is more about the emphasis than the outcome. Behaviorists suggest that the environment shapes the child's ideas about gender, and cognitive theory suggests that the child's cognitive development helps drive her awareness of and interpretation of her environment. Systems theory is always interested in how nature and nurture interact. And we have a lot to say about that when it comes to gender development. Focusing on the biology of gender, it's true that there are some sex differences in our biological reactions. When boys are stressed out (and when men are stressed out) they release more testosterone, which gets them ready for a fight-or-flight reaction. In contrast, when girls are stressed out (and when women are stressed out) they tend to release more oxytocin, which triggers more of a tend-and-befriend response. This means that girls and women are more likely to respond to stress by taking care of others and focusing on their relationships. But what are the situations that stress us out? That's going to vary depending upon our history and our culture and other contextual factors. It isn't just about the biology, in other words. It's also about the larger environment around us and how it interacts with our biology. This concludes our coverage of early childhood. Who's ready to go to grade school? That's the next stop. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 7, p. 1 EPISODE 7.1 – MIDDLE CHILDHOOD: PHYSICAL AND COGNITIVE DEVELOPMENT In today's episode, we will discuss the development of body and mind during middle childhood, focusing specifically on physical health and cognitive development. Physical Development Most children are pretty healthy during middle childhood. If there is some kind of inherited genetic disorder, that tends to strike a person when they're very young or very old. Once we survive infancy, it makes sense from an evolutionary perspective that we would stay healthy until we are old enough to reproduce at least. Nevertheless, some children do face significant health problems during middle childhood. The two most common causes of health problems in middle childhood are asthma and obesity. Asthma is a condition where the airways are inflamed, and this makes it hard for the child to breathe. Asthma very rarely causes death, but it certainly can create many complications. Asthma is a common reason why children miss school, and those who have a genetic predisposition are especially likely to develop the condition. Why do some kids with a genetic predisposition get it, while other people don't? Environmental factors can make a difference. In fact, one of the reasons why experts think that asthma rates have increased so greatly is because of the fact that we spend more time inside, with our windows closed, in homes that are insulated so well that allergens get trapped inside. These factors together can create an increased environmental risk of asthma. In addition, we may be overprotecting our children. When we keep things so incredibly sanitized, using antibacterial hand wash, for example, this may leave our children with an underdeveloped immune system. Basically, their body hasn't had to fight off many germs in the past. Their immune system hasn't been put to the test and hasn't had the opportunity to build up immunity. Small allergens, then, might end up being more disruptive to their health as a result. Ironic, isn't it? We try to protect our kids so much that we actually may be leaving their immune system weaker as a result. Obesity is another condition children may struggle with. Like asthma, obesity rates have increased greatly. Today, about 19% of children are obese, using the BMI calculation. BMI stands for body mass index. 19%. It's especially shocking when you compare that rate to the rate in the late 1960s, when only about 5% of children were obese. What has happened? It's true that some people are genetically predisposed to becoming obese. But it's also true that lifestyle factors play a strong role. Children are less physically active than they used to be, for a number of reasons. They get less exercise at school, because many schools decide to cut down on physical education in order to make time for topics that are assessed on standardized achievement tests. At home, children watch more TV than they used to, and they are less likely to play outside. More children live in big cities today than ever before, and this adds to the problem because there are fewer areas where children can play safely in densely populated urban neighborhoods. Diet matters as well. Our children are drinking more sugary drinks, and these empty calories add up quickly. Plus, affordable and healthy food is harder to find in densely populated urban areas, especially in low socioeconomic status neighborhoods. You're more likely to find a convenience store or a fast food restaurant than a good grocery store. Obesity in children is a major risk factor for other physical problems, like heart disease and stroke. Even if obese children lose weight as they grow up, their risk for these health problems later in life still remains elevated compared to those who were never obese. One of the best things adults can do, and parents in particular, is to model and encourage healthy eating and physical activity themselves. Children pay attention to what their parents do, and they are more likely to learn through observation than through being scolded or lectured about their eating habits and physical exercise. Theories about Cognition Our main job during middle childhood is to learn. What's the best way to make sure our children are learning? Well, we need to understand how their minds work, and we need to think about the P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 7, p. 2 best ways to set up our schools to motivate and encourage their best thinking. We've already talked a little bit about Piaget and Vygotsky, and their work is relevant to understanding cognition in middle childhood. Piaget focused on the individual child and her process of discovery. He was interested in how the child's encounter with new experiences helps them build their schemas, and in middle childhood the main advancement that occurs is in logical thinking. Remember, "operations" in Piaget's terminology refer to logical thought processes. The child is no longer held back by their egocentric thinking, or by the focus on appearance that was common during the preoperational stage. Now, they are able to reason logically about concrete things, things that are real. They certainly are capable of conservation, but they also gain skills in classification. Children can understand how objects of different sizes could be organized and ordered, from shortest to longest, or skinniest to fattest, and so forth. This is called seriation. Their logical thinking also allows them to consider the relationship between objects. For example, transitive inference is the ability to understand that two things are related because of the way each is related to a third thing. They're making a transfer of logical information. The example in the text is a good one, so I'll use it here. Let's say one child is told, “John is taller than Jim. Jim is taller than David. So, who is taller, John or David?” In middle childhood, we can make that leap. We have not been directly told that John is taller than David, but we can infer that by knowing the relationship between John and Jim, and the relationship between Jim and David. Transitive inference. It's clear that we become more objective thinkers in middle childhood, but Piaget's original claim that we make a fairly distinct shift toward logic in middle childhood is not quite accurate. It is more of a gradual development. We see the beginnings of it near the end of the preoperational stage, and it increases into the grade school years. Vygotsky was also interested in how children think, but he emphasized how children learn through the help of others. The more communal experience is his view point. Children can learn more when they are helped by an older person or a wiser person in their community. The older and wiser person structures the learning environment so it brings the child into what Vygotsky called the zone of proximal development. This is a range of tasks that the child is able to complete with the help of others, but wouldn't be able to do on his or her own. Instruction matters, in other words. Instead of being so focused on the child's individual discoveries, Vygotsky emphasized the role of others and the role of culture. Culture influences what a community considers to be important, which then influences how parents and teachers instruct children. Within our communities, we develop different knowledge bases. The knowledge base is a collection of knowledge that builds up over time and through experience. The larger our knowledge base on a given topic, the easier it is for us to learn new information about that topic. In other words, whatever has been emphasized the most within a given culture is absorbed and learned by children, building their knowledge base, and making it easier for them to continue to learn about that topic. This is what happens with any kind of expertise. I used to wonder how my professors could retain all of that information. They just seem to know so much, and I wasn't sure I could ever get to that point. Now I understand. You study a topic for such a long time, and you get faster at learning new things about that topic because of the knowledge base you developed. You don't have to have a PhD for this to happen, of course, because we're talking about how this happens even in children. It's about repeated exposure to the kinds of learning activities and topics that are most valued within a given culture. Of course, it's clear to modern developmental psychologists that we have to pay attention to the discoveries of the individual child, discoveries the child makes on his or her own, and the learning context and cultural context in which the child has been raised. Piaget and Vygotsky took different approaches to cognitive development, but both approaches help us understand the child's experience. Both approaches help us learn how best to interact with children and stimulate their cognitive development. Information Processing and The Brain Between our ears, we have a finely tuned device: the brain. Even before we were born, the brain P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 7, p. 3 was an amazing organ. As we develop, neural pathways form and get refined: pathways that are used often are retained, and new pathways are built based upon experience. It's a gradual development, although we've already discussed how there are spurts of change that occur. Infancy, for example, is an important time when there is a proliferation of synapses forming between neurons. And then there's pruning, with unused synapses disconnecting so that the brain can focus on the connections that are most important. With this gradual brain development, we also gradually see improvements in children's ability to pay attention, to sit still, to remember things, and to develop strategies to improve their thinking and memory. The prefrontal cortex continues to gradually develop over the childhood years. Remember, this is the part of the brain that serves as the central executive, helping to direct the functioning of all other areas of the brain and allowing us to become better and better problem solvers. In addition, the corpus callosum has developed to such an extent by this point that there is more coordinated communication across the hemispheres of the brain. Thanks to these improvements in brain development, we end up with a brain that is much more capable of handling the demands of the classroom. Have you ever tried to get a three-year-old to sit still? It's very, very difficult. But by the age of five, children are getting better at this. The older the grade school child, the easier it is for that child to sit still and pay attention. It also helps if the classroom that they're working in is structured, and if they have a quiet space at home to do their schoolwork. There are certain patterns of responses that we use so often that they become automatic. This is referred to as automatization. Imagine learning how to write your name. At first, it took you a very long time and a lot of very focused effort. If you look back on my baby book, you'll see that I used to have a really hard time with the Y on Amy. It was usually backwards. That was back when writing my name was not yet automatic. Once you have to write your name over and over again, thanks to the neural networks connecting the neurons involved in that task, and thanks to the repeated practice that strengthen those connections, writing your name becomes automatic. The brain, the information processing machine, becomes finely tuned and can complete tasks far more quickly than it used to be able to. This frees up brain space so we can contemplate higher-level tasks, so that you don't have to painstakingly think out every little letter when you're printing words. But you get better at writing and spelling so that you have the brain space to be able to think of more complex ideas and write those down. Some experts suggest that summer vacation puts children at a disadvantage because it's a break in the regular practice that they had engaged in with all of those mental activities during school. The brain really is like a muscle in that way: if you work out on a daily basis but then skip three months in a row, you lose some of your muscle tone. We may lose quite a bit in those summers when there are a couple of months in a row with much less cognitive stimulation and exercising of the information processing machine. When we encounter information it enters through our senses and stays for just a few seconds in sensory memory. We can't pay attention to every single thing that enters our senses at every moment, so we choose to focus on some things more than others and bring that information into our working memory. Working memory is where were doing our conscious thinking right now. You are using your working memory right now as you listen to me. You're hearing me talk about something, that information is entering your ears, and you are connecting it with other things you already know or that you are familiar with. As we develop, our working memory gets larger. It can hold more and more information in a given moment as we get older. Then, after we reach adulthood and move into older adulthood, working memory begins to decrease. But during the middle childhood years, we see a steady increase in working memory capacity. When we attend to information in working memory, some of it gets transferred to long-term memory. That's where we store our memories for a certain length of time, whether it's for 10 minutes or 10 years. As far as we know, there is no limit to how much information we can hold in our long-term memory. But the trick is retrieving that memory later. It doesn't really matter how much we stored there if we're not able to retrieve it all later. This is where strategies become important. We begin to develop P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 7, p. 4 strategies for remembering things, tricks that will later help us retrieve information. The prefrontal cortex helps us develop, remember, and successfully apply strategies. When we think about our thinking, that's called metacognition. It's an important part of building and using strategies. We need to be able to have an awareness of how we are thinking in order to evaluate our thinking and try out strategies. One particular component of metacognition is metamemory, which involves learning how to best use our memory, figuring out what it takes to be able to remember something. Children's brains make them capable of doing this in grade school, and the continued maturation of their brains will result in improvements in this ability as they age. But we can help them too. And we often do help them, with sayings and reminders and other tricks. When share reminders and tips to help them with their memory, we're giving them lessons in metacognition and metamemory. EPISODE 7.2 – MIDDLE CHILDHOOD: EDUCATION, INTELLIGENCE, AND DEVELOPMENTAL PSYCHOPATHOLOGY This is the second episode about the development of the body and mind in middle childhood. The focus is on education, intelligence, and developmental psychopathology. Learning Language and Math It may be hard to believe, but there was once a time when experts thought that it was a bad idea for children to learn a second language. They were worried that it would be too difficult for the young mind to keep track of two different languages, and that it might slow down their overall cognitive development if they tried to do so. That's not the case, recent research shows us. But we have a big challenge in the United States right now. We have 4 million students who are currently learning English as a second language. These are referred to as English Language Learners. It really presents a challenge in the classroom, because we want to do our best to teach these children - understanding that it's going to be difficult for them - while at the same time not holding back the native English speakers in the classroom. The biggest trouble is when immigrant children do not learn the language used at school, or at least when they don't learn it very well. It can become a problem that is compounded as they develop. So we need to do the best we can to teach as much English as possible, and to teach it as well as possible, during the middle childhood years, so we can avoid the negative snowballing effect. It's especially true once we reach middle childhood. Younger children, like children in preschool, pick up a lot more just by being around the different language that's being spoken. But the older we are when we start to learn our second language, the more difficult it is for us to learn simply from context. The more it becomes a separate cognitive task that requires a lot of effort. So what do we do? There are a few different approaches that have been attempted. What seems to matter more than the specific approach is the child's experience of learning a second language. Regardless of whether the child is experiencing bilingual education, ESL instruction, or immersion, what matters most is whether they feel confident and up to the task. If classroom practices or policies or teacher attitudes lead students to feel inferior or stupid as they are learning English as their second language, this can have a detrimental impact on their ability to learn. Just think of how you feel as you sit down to take an exam on a topic that has always made you feel nervous. For me that would be math. Whether it's really true or not that I'm bad at math, I have this idea that I'm bad at math. I have an idea that I'm inferior when it comes to math. Those kinds of thoughts are playing in the back of my mind as I try to complete some kind of math problem. That's the kind of thing that some children who are learning English as a second language have to deal with, and if this is a problem they experience in middle childhood, and it's not resolved, it becomes a constant source of struggle for them. At least with me, as soon as I could, I stopped focusing on math. But, the English language is so central to everything that we learn in school that it is a significant hindrance if a child during grade school has developed a sense of inferiority about their Englishspeaking abilities. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 7, p. 5 The text refers to "the education wars." Sounds pretty dramatic, doesn't it? What's the best way to teach our children how to read? What's the best way to teach our children math? Well, one thing is for sure: there are no simple answers. And we tend to go through phases where we think certain techniques are superior to others, but then further research may reveal a new technique that becomes popular and trendy for a while. Sometimes the trouble is that we look for a magic bullet, something that's going to make a big change on its own. In the end, we usually end up finding that it's a mix of different approaches that works best. Take the phonics approach versus the whole language approach. I remember learning phonics. We were repeating sounds of the English language, what linguists would call phonemes (like the TH sound in the word "truth", or SP sound in the word "spell"). The idea was that by learning those sounds, phonics, they would help us build words. Phonics involves rote memorization and it's a very piecemeal approach to language. A different approach is the whole language approach, which is focused on how language is used in context. I have experience with this as a preschool teacher, where we would encourage children to write when they wanted to, but we wouldn't give them instruction on what was correct or what was incorrect. The focus was to encourage their motivation to communicate. We would also ask the child to tell us a story, then we would write their story down in their exact words. It's a very natural, holistic way of looking at language. But children don't come in just one variety. Some children benefit greatly from whole language approaches, whereas others really need the bit-by-bit focus of phonics. Why can't we do both? Yes, we should encourage children's motivation to communicate. We don't want to discourage them with early and repetitive corrections to everything they write or say. At the same time, it can be very useful for them to practice the sounds of the language. So it's best for us not to take an extreme view on either side, but to consider the particular child that we are dealing with and what he or she seems to need the most. There are some parallels to the language war in math instruction. It's a similar kind of dichotomy between a method based on rote memorization (old math) and a process of self-motivated discovery (new math). Add to this divide the anxiety that we feel as a nation when we notice that our math scores are significantly lower than those of children in other nations. It makes us nervous thinking that our math instruction is inferior. Guess what? The research suggests that a strictly old math approach is ineffective, and a strictly new math approach is also ineffective. Instead, what tends to happen is children learn strategies and use these strategies in waves. They learn a new strategy and begin to use it gradually and build up until they're using it more and more and more. The strategy becomes more automatic. And then they gradually use the strategy less and less as they adopt more sophisticated strategies. Similar to phonics, we need the bit-by-bit instruction that comes from memorizing multiplication tables, for example. But that's very boring to most children on its own, so we also need to think of math more holistically and set problems up so that it's an experience of discovery for the child. As with all educational matters, what we really need is good long-term research to find out which combinations of techniques work best. It's quite a challenge, though, because education quickly becomes politicized. And once things become politicized, we tend to lose our patience, patience that really is required to study things as carefully and is in-depth as possible. Measuring the Mind There are many good reasons for wanting to understand the grade school child's current level of academic achievement and their potential to learn new material. IQ tests assess aptitude, which is the child's potential to learn new material. This is not the same thing as an achievement test, which assesses how much a student has learned (in the past) about a particular topic. So, aptitude is all about potential to learn. We make a pretty big deal about IQ, probably a bigger deal than the original creators of the first IQ test intended. IQ tests were created in France in the late 1800s when the French Ministry of education decided that all children needed to attend school, regardless of their background. The French recognized that this was going to be a challenge, P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 7, p. 6 because teachers we now have a much wider range of abilities present in their students, and teachers would need to know I had of time which students were likely to need extra help. By now we've used IQ tests so extensively, and their scores have been misinterpreted and misunderstood quite often, so that there is a lot of understandable skepticism amongst the general public about what IQ tests are really showing us. Perhaps the biggest question is about how much control we have over our IQ? How much control do we have over our children's IQ? What impact can the environment have on IQ scores? For years, experts thought that IQ is basically a product of our genes, something you're just born with. Now we know that, even though it's true the genes play a significant role in IQ, the environment most certainly makes a difference. The Flynn effect shows this very clearly. The Flynn effect is the phenomenon that a scientist named–guess what?–Flynn discovered as he looked at raw IQ scores over the past 100 years. These scores have increased consistently, and not just in the United States but all across the world. It's not that the smarter people are mating and producing even smarter offspring, though. Evolution doesn't happen that quickly. No, what's happening is that we are healthier, we have greater access to information, we spend more time in school, and we tend to have fewer kids in each family. All of these factors of the environment correlate with intelligence. As I stated earlier, the original authors of the first IQ test were hoping that it would help teachers identify students with mental retardation, so that those students could receive extra help instead of being punished or overlooked. By the way, I want to explain that the technical term that we still use is “mental retardation.” This phrase may hit you the wrong way. I don't blame you if it's a term that you dislike. And, times are changing, and I wouldn't be surprised if very soon we are referring to mental retardation as intellectual disability instead. If, on the other hand, this whole discussion is irritating and you wish we weren't so politically correct, I'd like to draw your attention to a historical comparison. Words like imbecile and moron and feeble-minded all used to be technical, scientific terms used to refer to individuals with lower scores on intelligence tests. Could you imagine if today scientists referred to a child as an imbecile? Of course that is offensive. And we may be moving into a time when mental retardation becomes an obviously offensive term. We're not quite there yet. But I imagine were pretty close. My goal is to teach you, and in so doing I need to stick with the terms that are still currently in use. Speaking of mental retardation, we used to have really straightforward way of identifying it: if the child had an IQ below 70, they were considered mentally retarded. That's no longer enough information to make a diagnosis these days. Scientists have learned a lot more about functioning at the lower levels of intelligence, and now the mental retardation designation is not used unless the child has an IQ lower than 70 and has difficulty with activities of daily life (ADLs). ADLs are basic activities of daily life, like dressing yourself, recognizing your classmates by name, and taking care of personal hygiene. At the other end of the scale are the so-called gifted children. Usually, we consider children with an IQ of 130 or higher to be gifted and talented, and, depending upon the state in which they are growing up, they may or may not have access to special gifted and talented classes. Of course, IQ tests are not free of criticism. A low IQ score may reflect a low potential to learn, or it may also reflect cultural differences. IQ tests involve items that use language and scenarios common to the culture within which they were developed. It's also quite possible that IQ tests do not capture all of intelligence. What if there's more than one kind of intelligence? An IQ test is not assessing that. Robert Sternberg suggested that there are three different kinds of intelligence. Academic intelligence is the kind that is measured on IQ tests and achievement tests, but creative intelligence and practical intelligence are not. Creative intelligence reflects an individual's ability to come up with very original ideas, and practical intelligence refers to the ability to problem solve in real life situations. Do you know someone who's really smart at school but doesn't make good decisions in daily life? That might be someone with high academic intelligence but low practical intelligence. Beyond Sternberg, another type of intelligence that has been proposed is emotional intelligence. I P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 7, p. 7 think this is a really interesting concept. Emotional intelligence has two parts to it: the ability to understand and regulate your own emotions, and the ability to understand what other people might be feeling. Let me just focus on that first part: understanding and regulating your own emotions. This is so important for success in life. There could be 1000 other things you'd rather do than work, and, if you are incapable of regulating your emotions, you might consistently procrastinate or even fail to do the important things you need to do because you're so motivated to follow all of your emotional whims. Someone might even have really high IQ scores, but might hold themselves back because they have such difficulty regulating their emotions and pushing through the tasks that they don't really enjoy. Now, the whole intelligence situation can start to seem a little ridiculous by the time we talk about Howard Gardner, who at this point has identified about nine intelligences. But maybe he's on to something. Based on research looking at people who are amazingly talented in certain areas, Gardner suggests that there are many different ways to express intelligence. We can be intelligent in terms of our musical abilities, for example. Perhaps we are intelligent in terms of how to move our bodies, something he called bodilykinesthetic intelligence. Think of athletes or actors or dancers on this one. Gardner thinks that we all have some ability in all nine intelligences, but we vary from person to person. I would guess that my musical intelligence is pretty high, for example, but that my spatial intelligence is quite, quite low. Think about where you would fall on these different intelligences. Gardner's multiple intelligences have really caught on in certain areas of education, where schools have even been founded on the principle of providing children with opportunities to find out which of the nine intelligences they excel at. Critics of Gardner, on the other hand, are concerned that the definition of intelligence has been stretched too far. I think critics get particularly suspicious because Gardner adds a new intelligence to his list every once in a while. There used to be seven intelligences, and then there were eight, and now there are nine. That doesn't mean there are limitless kinds of intelligences, but I do understand why scientists are cautious. Perhaps it's best to think about these intelligences as potential talents, and certainly to keep in mind that an IQ score is just one facet of a person's abilities. Achievement tests are different from IQ tests. Achievement tests are designed to measure how much a child has learned about a particular topic. We have all taken some kind of achievement test. The No Child Left Behind Act of 2001 has certainly stimulated lively debate about the proper role of achievement testing in the United States. In addition, our achievement test scores do not compare very well to other nations, especially when it comes to science and math scores. Children who grow up in East Asia outperform us and the rest of the world in math and science. Why is this the case? It might be tempting to think this reflects some kind of innate ability in science or math, but aptitude tests do not show differences across countries. Our potential is the same, so why is our achievement different? We're not going to come up with one answer for this question. There are a few likely candidates, a few reasons that probably work together to explain the difference. In East Asian countries, the school year last longer and the school day last longer. It may also have to do with the training of our teachers. East Asian teachers of math and science have more extensive training in teaching itself, whereas in the United States we are more concerned that our teachers have content expertise. We provide relatively less direct instruction on how to teach math and science. There are some cultural issues that also are likely to play a role, including confidence and attitudes. Paradoxically, high confidence may not be such a great thing. In the United States, our children are more confident in their math abilities than their scores indicate. It's the opposite in East Asian nations, were children have lower confidence than their scores indicate. In other words we think we're good at math here in the U.S., but we really aren't, and they think they're not so good at math, but they really are. Why does this matter? Scientists think that it leads East Asian children to work harder and persist in the face of difficulty. Attitudes about intelligence matter as well. In the United States, we tend to think that intelligence is largely genetic and that we either have a certain talent or we don't. I know that I have fallen prey to this idea when it comes to my own math abilities. I find myself saying things like, “I'm not a math person.” That makes it sound like it's some sort of fixed ability, written into my genes. The P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 7, p. 8 research shows us that this attitude can cause us to stop trying. We think, why bother? Math just isn't my thing. Imagine having a much different attitude, thinking that math ability isn't in the genes, but that it is largely the result of hard work. Then, if we fail at a math problem, our strategy would be to work harder. Some cross-cultural research suggests that East Asian children, and East Asian cultures in general, adopt the attitude that it's about hard work. Maybe that's another reason why they do so well on these math achievement tests. Developmental Psychopathology We all understand how important it is to accurately assess achievement in school, but it's equally important to investigate whether children have special needs that might interfere with their ability to learn. We have seen an increase in children with special needs in the United States, and it's not clear whether we're just doing a really good job of identifying problems or whether we are overdiagnosing our children. A field of study that helps us figure this stuff out is developmental psychopathology, where normative development–and that means development that is typical–is used to provide us insights so that we can identify atypical development. For example, it's really quite normal for children to behave abnormally sometimes. It's also quite normal for children with disabilities to show different symptoms at different ages. A child's attention deficit disorder may come out in very different ways when they are in grade school than it does when they are teenagers, for example. As we grow up, change is a guarantee. This is true of special needs as well. They will change, but they may improve or get worse. The only thing we know for sure is that they will change. In trying to diagnose children, we also have to consider the children's behavior is influenced by cultural context, historical context, and other aspects of the environment. These factors have to be considered when professionals are determining a diagnosis. One disorder that gets a lot of publicity is Attention Deficit/Hyperactivity Disorder. It can be confusing because you may hear it referred to as ADD or as ADHD. Technically, the diagnosis as listed in the Diagnostic and Statistical Manual of Mental Disorders is AD/HD. So what we used to refer to as just Attention Deficit Disorder would now be considered part of the AD/HD diagnosis. Most children diagnosed with an attention deficit disorder are boys, but there is evidence that girls' experience of attention deficit is significantly different than boys' experience. As a result, we may be missing the symptoms in our girls. But, the attention deficit that most of us have heard about is the kind that's more common among boys, and involves not only difficulty paying attention, but also impulsive behaviors and overactivity. These are the children who end up being very disruptive in class, and that's one reason why attention deficit disorders often become very apparent in the grade school years, perhaps for the first time. Think about it. This is when we expect children to sit still and focus on tasks. But that inattentive aspect of attention deficit disorders can also come out in a child's behavior in ways that aren't so obvious. Maybe the child tends to daydream, or perhaps the child has difficulty screening out irrelevant stimuli. Let's say there's a projector in the room that's making a persistent humming sound. Most kids just tune it out, and they may not even notice the sound at all. Other children, on the other hand, maybe incapable of screening out that distraction. They're not necessarily running around or tapping the table or talking to their neighbors. Their experience of attention deficit might be very private, just going on in their own mind, but making it difficult for them to focus and do their best at school. Like other special needs, diagnoses of attention deficit disorders occur a lot more often here in the United States compared to other nations. Obviously, this is cause for concern. But let's not jump to the conclusion that we must just be over diagnosing our children. Yes, that's one possibility, and a possibility we need to take seriously. But, attention deficit disorders are real. They do exist. And they are quite challenging for children to deal with. Properly diagnosing them and treating them can make a world of difference for children. Oftentimes, medication is prescribed. Stimulant medication is most commonly used for children and adults with AD/HD. This can seem confusing at first glance; I mean, why are you giving a hyperactive child a stimulant? P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 7, p. 9 Well, this helps you understand the unique physiology of an individual with AD/HD. The best research we have so far suggests that the brain of a person with AD/HD is actually understimulated. The reason why the child may pick up on every tiny little distraction, or the reason why the child feels the need to jiggle his leg nonstop or tap the desk with his pencil, could be that child's way of trying to keep himself alert and interested and not completely bored out of his mind. Stimulant medication acts on neurotransmitters that help increase brain activity, bringing it up to a more typical level so that the child is able to actually calm down and focus. You can understand why parents are concerned about putting their child on medication, and medication is not required for all children with AD/HD. The most important thing is that the child goes through a very thorough diagnosis process with a trained professional. You don't just want a general practitioner diagnosing this in the child. You want a child psychologist or child psychiatrist who specializes in AD/HD. And there are treatment options. It's true that most children benefit from stimulant medication, but it's also true that children can benefit greatly from behavior modification and other forms of therapy as well. In many cases, it takes a combination of the two. Another set of disorders that get a lot of attention these days are Autistic Spectrum Disorders. Autistic spectrum. The word spectrum indicates that there is a range of possibilities. A child may be mildly autistic, which we refer to as Asperger syndrome. A child with this disorder has great difficulty with social relationships. They may have a very hard time understanding the social cues that the rest of us just seem to already know. There was a student in one of my classes who told me in private that she was diagnosed with Asperger syndrome. She told me because she wanted me to know that when she stayed after class to talk and ask questions, I would have to very directly tell her when it was time for us to stop. Imagine what I mean by this. If you've ever stayed after class to talk to your professor, you pick up on the signals. The professor might be talking as she's putting away her things, and eventually she's got all her stuff packed up, and she's walking toward the door. By now you know that the conversations is going to end soon. The social cues are obvious to you, but they wouldn't necessarily be obvious to a person with Asperger syndrome. They may be so absorbed paying attention to the details of the conversation that they are not even noticing the social cues. Indeed, individuals with Asperger syndrome tend to be highly intelligent in certain areas. So it's really the social cues that they struggle with. Moderate or severe autism is quite different than Asperger syndrome, however. Children with moderate or severe autism may not develop language skills. The child may seem to be in his or her own world, almost unaware of others. The things that most children like, such as getting hugs and kisses and attention, can feel completely overwhelming to the child with autism. There's been great concern in the United States because the number of children diagnosed as autistic has risen quickly in the last few decades. One explanation is that we've gotten much better at identifying autism. Children who might have been diagnosed as mentally retarded 30 years ago may now be correctly diagnosed with autism instead. There has also been a lot of questioning about whether environmental causes could be involved in this increase. As we discussed before, some still believe that vaccines cause autism, even though the research has shown repeatedly that there is no increase in rates of autism among children who have been immunized. Furthermore, the ingredient originally believed to be the link between vaccines and autism no longer exists in today's vaccines. That ingredient is thimerosal. Since this ingredient has been taken out of vaccines, rates of autism have not dropped. In fact, they have risen. Perhaps some other environmental agent plays a role, but we just haven't yet identified it. But the best evidence so far suggests that there is a genetic component. Do we know exactly what that genetic component is? No. Do we have some ideas? Yes. This is an area that scientists from many different disciplines are working on quite intensely. That's it for the development of the body and mind in middle childhood. Next, we turn to the social and emotional world of the grade school child. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 8, p. 1 EPISODE 8.1 – MIDDLE CHILDHOOD: INDUSTRY, RESILIENCE, AND FAMILY INFLUENCES The question of “Who am I?” is often answered in middle childhood with “What I like to do,” or “What Iʼm good at.” As preschool kids, we thought we were good at everything. We didn't have a very realistic understanding of our abilities, but it didn't seem to bother us too much then. Grade school kids have a growing sense of who they are, what they really like to do, and what they're pretty good at. It helps that kids have all kinds of physical energy at this age, energy they can direct toward a million activities to keep them busy discovering their skills. Industry Erikson believed that middle childhood was a time of energetic activity, as children strive to figure out what makes them special. If all has gone well in psychosocial development up to this point, the child will enjoy trying out new things and will learn from experience how his/her skills compare to those of others (especially peers). The potential negative outcome is that a child will feel cynical about his/her skills and will not feel motivated to engage in meaningful activity. Erikson refers to this stage as industry versus inferiority. Industry refers to a sense of being engaged in some kind of meaningful activity that uses our skills. The child will enjoy trying out new things and will learn from experience how his or her skills compare to those of others. Children are especially interested in how their skills compare to their friends' skills. They make social comparisons to figure out how they fit amongst their peers in terms of their abilities. Cultural influences are certainly playing a role, because children are most interested in mastering the types of skills that they have learned are important in their culture. It's not easy to figure this all out, though. But children at this age are much better at regulating their emotions, and they have to regulate their emotions as they try new things and deal with the outcome. They have to learn how to tolerate not being good at everything. Grade school children are eager to do a good job at whatever they try, so it's a challenge for them to manage their feelings of inferiority when they find out they're not so great at a certain skill. We also don't want children to just give up immediately after one bad experience. Just because they had one bad day at softball practice doesn't mean they have no talent for athletics. The ability to persist even when you feel doubtful, and to eventually realize if a particular task just isn't your thing - this is a skill. Effortful control helps: It has been developing thanks to the prefrontal cortex, and it is kind of like industry used toward emotional regulation. Parents are an important influence. Ideally, parents nurture the child's curiosity and energy and interest in trying new things, and parents help guide the child's emotional regulation when things don't turn out as they hoped. The risk of the child developing an overall sense of inferiority is increased when parents are inattentive to the child's interests or even seem annoyed at the high energy level of their child. And of course, the child's genetic predispositions bring something to the situation as well. Highly sensitive children who are prone to anxiety are most likely to have a very difficult time managing their feelings of disappointment and self doubt. I bet that if I were to ask you, "When in the lifespan are we most concerned about figuring out who we are?" You would probably say, "The teenage years." And you wouldn't be wrong. But the quest to figure out who we are, what we're good at, and how we fit in compared to everyone else, begins in middle childhood. We start to think about our thoughts more often, analyzing them, mulling over our perspectives, considering ourselves as people who are different from our parents. Most children at this age are still P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 8, p. 2 rather close to their parents, but they are increasingly aware of the fact that they are autonomous individuals who have their own interests and abilities apart from their parents or anyone else in their family. They're also making comparisons between themselves and their friends to figure out their place in the social hierarchy. This can put a big wrench in their self-esteem, but that's not necessarily a bad thing. In preschool, our self-esteem is unrealistically high. It's cute then, and it helps fuel our sense of initiative. But, by the time were in grade school, it's important as we mature to start developing a more realistic understanding of our abilities and our goals. Please understand that I am not suggesting that children should aim low. Not at all. Rather, by building a sense of industry and understanding our skills, we gain a more realistic self-esteem. Self-esteem is one of those things that's kind of like Goldilocks and the porridge: we don't want it to be too high, we don't want to be too low, but we wanted to be just right. I think it's clear the problems that can come from low self-esteem, right? If we have an unrealistically low evaluation of ourselves, we may not even try. It's kind of like presuming we're going to fail at something, so maybe we don't even go for it and all. Low self-esteem is correlated with depression. But unrealistically high self-esteem also carries with it some significant risks. In fact, some of the risks are the same as those of unrealistically low self-esteem. In both cases, children struggle with effortful control. They find it challenging to regulate their emotions related to their achievements. A child with low self-esteem who has a minor setback may interpret it as a catastrophic failure. A child with unrealistically high self-esteem who has a minor setback may retaliate and blame others for his or her shortcomings, a reaction sometimes fueled by aggression. So, in both cases, unrealistic self-esteem is connected to emotionally reactive tendencies. All of this research, by the way, comes from a Western cultural perspective where self-esteem is highly valued. Think about it. In cultures where independence is so highly valued, self-esteem makes a big difference. You're supposed to figure out who you are and forge your own unique life path in Western societies, which means that your attitude about what you are capable of doing is critical to success in life. But we can take that too far sometimes. Self-esteem doesn't magically lead to achievement. The research does not support this. It's the other way around, actually. Once we've had meaningful successes, our self-esteem rises. Resilience and Stress We would certainly like to spare children of chronic stress, and it's hard to imagine how a child can cope with a traumatic experience. They cope in a variety of different ways. One of the tricky things about it, though, is that you can't always tell by the child's reaction how he or she is really coping. When anyone faces significant adversity, their resilience is put to the test, their ability to adapt. Some children are blessed with psychological characteristics that enhance their resilience, although there are no guarantees. Resilience isn't a single, stable personality trait, although children in grade school show more resilience at this age than ever before. Grade school children manage the emotions, and the often significant changes that come with adversity, better than they would have as preschool children. Also, adapting to a situation might involve dreaded changes that lead to unexpected, positive outcomes. Living through a parent's bout of alcoholism, for example, is tremendously difficult for a child. That child may have to go live with her aunt for a while, a change she isn't happy about. But, as a result, let's say she ends up growing closer to her aunt and other members of her extended family. The strength of that new relationship may help her adapt to the stress. Now she has a stronger relationship with another family member, a relationship that perhaps never would have grown so strong without the necessity created by her mother's alcoholism. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 8, p. 3 Any child is going to have trouble managing significant adversity, but the smaller, everyday stresses add up and take a significant toll. Daily hassles are the minor problems and irritations that come and go on a regular basis. Perhaps a child lives in a neighborhood where there's lots of noise, where it's impossible to have a long stretch of quiet. Or maybe he walks to school and has to pass through a dangerous neighborhood. Let's say he has a mentally ill parent and he has to take over some of the adult roles in the house, like making breakfast for himself and his little sister. It might seem to an outsider that the boy is coping quite well, but we should not be too easily deceived. It's often the case for children that one small thing on top of all of these other accumulated problems can be the straw that breaks the camel's back. In other words, a child may seem resilient as he handles a number of significant challenges, but the toll on his mental health may not become apparent until later. Let's say the child has survived Hurricane Katrina and seems okay, but several years later while dealing with the daily hassles of living in a poor neighborhood - like walking through a dangerous area on the way to school - he has a panic attack. The point is not to assume that everything is fine just because the child hasn't yet had a breakdown. Rather, we need to be perpetually aware and observant of children's well-being, understanding that some new stress might be the tipping point that uncovers the extent of the toll that those earlier event had on his coping skills. During the time of dealing with stress, the larger community may become involved in the child's care, and this is often a very helpful source of support. Children's social world is already getting larger in grade school, as they make new friends at school and begin to spend more and more time with their friends. Their friends' parents may become important influences, allowing a child to stay over when things are not going well at home or perhaps even acting as a model of how parents can be if the child's own parents are not healthy. The extended family can also act as an important part of the child's larger social world. Often times when a crisis has occurred, the extended family gets more involved in the child's life than they were before. The child's other social connections may come through institutions like their church, where they get to meet adults who care for them and adults who provide another positive role model. Furthermore, the belief system that's part of the spiritual community can help the child manage the stress of coping and consider alternative interpretations for what is happening in their life. Family Influences I'm sure by now you are very well aware that genes and environment influence everything about us. What is the first thing we think of when we imagine a child's environment? Parenting. Obviously, parents matter, but the scientific research suggests that parents contribute less and less of the environmental influences on our development as we grow older. It looks like they have their strongest influence in infancy. By middle childhood our environments have widened. For example, one big difference has to do with our experiences at school and our experiences with friends. These are clear examples of nonshared environmental influences - the influences that differ among children raised in the same family. My brother and I had very different experiences at school and with our friends, so, even though we had the same two parents - which comprised our shared environmental influences - there were significant nonshared environmental influences that were different for the two of us. And the research shows P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 8, p. 4 us that the proportion of influence shifts with age, where shared environmental influences have a smaller and smaller impact on our development over time, and nonshared environmental influences have a larger and larger impact on our development over time. But let's think more about the shared environmental influences that supposedly have a diminishing impact on our development. Is it really about parents having less and less of an influence? Or could it be that some of what seems to be shared really isn't shared? Let me explain. Yes, my brother and I have the same two parents. But he and I are not the same people. Yes, we have some personality similarities, but we also have many personality differences. We also have unique interests and talents. The experience I had growing up in my family during the late 70s as a young child was undoubtedly quite different than his experience as a teenager during those years. Plus, he was a boy and I was a girl, and gender certainly influences family experiences as well. The best we could really say is that parents' influence varies from one child to the next, so, just because we see differences among siblings in a given family, that doesn't mean that our parents had only a small influence. It's just that their influence on us was not uniform. We may have grown up in the same family with the same parents, but our experience of our parents is not exactly the same. Families have various functions, and families have different structures. Family function refers to the patterns of interaction that go on amongst family members, specifically the ways that the parents address children's needs. Those needs change with age, and those needs may differ from child to child, depending upon each child's predispositions. Obviously, healthy families serve the function of meeting the most fundamental needs, like keeping children fed, clothed, and safe. Children also benefit if parents are involved in their development, which, during the grade school years is going to include an emphasis on the child's education. Parents go to parent-teacher conferences, stay on top of children's school activities, ask about the child's homework on a nightly basis, and encourage learning through other kinds of activities at home or in the community. Children are struggling to figure out how they fit in, and they're vulnerable to feelings of inferiority, so healthy families encourage the child's sense of self-respect and competence, helping to point out and reinforce the child's strengths while also helping the child regulate difficult emotions that arise whenever things don't go as planned. Friends are becoming incredibly central to the lives of children during the school years, and families function ideally to encourage peer relationships, perhaps by suggesting play dates, getting to know the parents of their child's friends, and asking about how things are going with their friends. Children also thrive whenever they know what to expect in the household; in other words, it's best when children can count on a basic routine. There's a routine in the morning, a routine after school, a routine during the weekends. Life doesn't have to be 100% predictable, and children often enjoy a surprise or a change every once in a while. I remember the days when I took the school bus to Grandma's house instead of home. That was a fun change in the routine. But otherwise, I knew that when I arrived home after school, my mother would be there. Routines provide a sense of security. Children do not do well if life is so chaotic that they can never predict what will happen on a given day. Children do best when they understand that there's a basic stability to their lives, that there are predictable events that happen most of the time that they can count on. It helps them feel secure. Children are raised in families with different combinations of adults as parents. A family household is defined as people who lived together in the same home, where there's at P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 8, p. 5 least one child and at least one person who serves as a parent. About 68% of households in the United States are family households, and many of these households have children in grade school. The different combinations of relationships between people in a family, combinations that may vary because of legal reasons or because of genetic reasons, define the family structure. For example, the child may not live with his father. He may live only with his mother in a single parent household, seeing his father every other weekend. The majority of children are raised in a two parent family, although there are different kinds. The nuclear family is composed of at least one child raised by two parents, both of whom are genetically related two the child. Perhaps the child's parents have divorced, but one or more parents have remarried. The child may live in a stepparent family then. Divorced dads are most likely to remarry; divorced moms are less likely to remarry. When divorced moms do remarry, the children are more likely to live with her then with their biological father. A specific type of stepparent family is a blended family, where there are children from more than one family living together in the same household. Perhaps mom got remarried, and the stepfather had children from his previous marriage as well, and now both sets of children are living together in one household. This is the Brady Bunch scenario, although, as is often the case, what's depicted on TV may not match reality. The research tells us that blended families present a special kind of challenge for school-age children because kids are adjusting not only to a major change in their parental relationships, but also must deal with the challenge of managing new relationships with new, non-biological siblings. Technically speaking, parents who adopt a child are referred to as an adoptive family. It may surprise you to learn that only 2% of families are adoptive families. This number used to be much higher. The main reason for the decrease is that fewer pregnant women choose to give their children up for adoption. It was much more common in the 50s, 60s, and 70s than it is today. The vast majority of adoptive families are two-parent families, although it is possible for a single adult to adopt a child. However, today with the relatively small supply of adoptable children, expectant mothers have quite a long list of hopeful adoptive parents to choose from. And most expectant mothers would rather their child be adopted into a two parent family. We haven't yet talked much about single-parent families. About 28% of school aged children in the United States live in single-parent families. This means that there's one parent, one adult, in the family and no others. Single-parent families are particularly common among African-Americans, and single-parent families are most often headed by mothers. For a number of reasons, single-parent families tend to be less stable environments for children. But again, it's unclear how much of this is specifically linked to single parenthood, and how much is linked to other factors that usually (but not always) go along with single parenthood. Economic hardship is common, especially when the single parent is a mother. The research also shows us that single parent homes whether the parent is mom or dad - are more likely to have new people coming in and out, such as significant others. Also adding to the risk is the parent's stress. Single parents have a lot of pressure to fulfill all of the family roles for their child or children. There is only so much time in a day, and many single parents are stretched to the max. Certain aspects of family functioning are particularly challenging for child development. There are many aspects we could discuss, but I'm going to follow your text author's lead and focus on low income, instability, and social cognitive connections. Across all of these, the most influential impact stems from stress. Low income leads to stress. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 8, p. 6 Instability leads to stress. If the child's social cognitive interpretation of the family is distorted, this causes stress. So let's talk about the ways that each of these can contribute to stress. This is referred to as the family stress model. Low income may not have a huge impact on child development if there was just a year or two in the child's life when the family was under significant financial strain. But the truth is that when poverty strikes it's usually very long-lasting. Most children in low income families spend many years in poverty. Also, the places where they can afford to live tend to be places where the neighborhoods aren't safe, the schools aren't well funded, and there are fewer opportunities for children in general. It's also difficult for parents to be at their best when they're managing the stress of poverty. Some are able to manage it quite well and minimize its impact on children. But many parents are worn down by poverty, and you can see the outcome of this coming out in strained relationships in the family, whether it's marital conflict or conflict between parents and their children. Interestingly, the family stress model is not limited to low income families. Very high income families are also at risk because of stress that stems from pressure parents put on their children. It's interesting because you might think that children in high income families have it made; they don't have to worry about having enough to eat, they live in a nice neighborhood and go to a great school. But the competition and pressure that stem from trying to measure up to the other families may generate a lot of stress between children and parents. Indeed, the rates of emotional disorders are higher in high income families compared to middle class families. Back to low income families, escaping poverty can have a dramatically positive impact on child development. For example, Native American families who experienced a significant increase in income after a new casino was opened had children who showed a decrease in problem behavior. Research shows us that poverty is correlated with child psychopathology, this study of Native American families showed that lifting the strain of poverty can have dramatic, positive effects. By the way, there was no specific program to educate parents on different parenting techniques, or to educate children on their coping skills. All we know is that the financial stress decreased, and that problem behaviors decreased as well. This lends support to the family stress model. Presumably, with the increase in income came a decrease in the stress in the family, so that parents were able to forge healthier relationships with their children. Change makes most of us feel unstable, and adults sometimes don't realize how difficult it is for children to manage change. Children like things to stay predictable, and when there are too many transitions, children tend to feel a sense of instability that can negatively impact their development. Change can come in many different ways. Perhaps children have to move to a different city, state, or even country. This means they're going to have to go to a new school, make new friends, and deal with all kinds of changes. Let's say there's some kind of natural disaster or political conflict that requires a very drastic and immediate change. When such change happens, the research tells us that physical health and mental health are negatively impacted among children. If parents leave for significant portions of time, this is another major disruption. Military families have specific challenges that they must face, with one or more parents leaving for tours of duty, or, even during peacetime, dealing with the stress of the multiple moves that are common in military families. We see the biggest challenges when a child is forced to deal with several changes in a row. Let's say that parents get divorced, the children live P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 8, p. 7 with mom, mom gets remarried, the family moves to a new city, the children have to change schools, make new friends, and learn how to get along with stepparent. When changes pile up like this, it's very taxing on the child's ability to cope. We are all individuals, and each of us sees the world in our own unique way because of our social world and our unique interpretations (or cognitions). This is true of children as well. One situation may be interpreted very different by each child in a family. Interpretation matters. What influences children's interpretations? Certainly, each child has a temperament and other predispositions. Some are simply more resilient than others for a variety of reasons. But there are other factors that influence their interpretations as well. Parents' approach to the situation can make a huge difference in children's interpretation. One study of marital distress and children's functioning found that the strongest impact on the child's psychological and academic adjustment was the child's feelings of self blame and instability. It mattered less exactly how much conflict was going on in the home. It mattered more how the child experienced that conflict. In other words, there could be just a moderate amount of conflict in the home, but perhaps because parents have fought openly in front of their child, or maybe one parent has tried to get the child to take his or her side, or the child somehow believes that he is the reason why his parents are unhappy… all of these can contribute to a strong sense of self blame and vulnerability in the child. One of the best things parents can do when they are having conflict with one another is to do their best to keep the child out of it. Of course, this isn't always practical. Parents are sometimes going to argue in front of a child. Even if parents manage not to argue in front of the child, the child is still going to pick up on tension and discontent. How parents handle it matters greatly. Sometimes parents can't work through it, for a number of reasons, some of which may be very legitimate. Let's say that one parent has been unfaithful to the other. Divorce is inevitable, perhaps. If parents can do their best not to involve the child in the conflict, that's best for child development. Don't let the child hear you badmouth the other parent. Do your best not to sigh and roll your eyes when dad arrives at the door to take the child for the weekend visit. What I'm saying is, to whatever extent possible, if parents can refrain from dragging their child into the conflict, that helps the child maintain a healthy perspective on what's going on in the family. We may not be able to prevent conflict from occurring, but we can do a lot to lessen its impact on the child. EPISODE 8.2 – MIDDLE CHILDHOOD: PEERS AND MORALITY This is the second episode about psychosocial development during middle childhood. This episode focuses on peers and morality. The Peer Group Do you remember how important friends were to you in grade school? It's like there was this whole new world that you entered when you went to school. You got to hang out with people who were the same age as you, people at the same level of cognitive development as you, people who had limitless amounts of energy like you did. That all sounds great, right? And it is, for most of us most of the time. But we have a lot to learn from her peer relationships in the grade school years, and some of that learning can be painful. In grade school we no longer have the blessing of egocentrism to protect us from understanding others' opinions about us. We become more aware of what other people think of us, and, if we behave in a way that other people don't like, we are going to hear about it. Our peers are probably going to tell it more like it is than our parents will. Our parents are motivated to soften the blow. Our parents also see the good in us. But, on P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 8, p. 8 the playground, if you did something not so nice, your peer is likely to turn around and yell at you, “You are mean! I don't want to play with you!” That is some pretty harsh feedback. Most of us learn from this feedback and gain important social skills in the meantime. This group of children, this world of children, that we enter in grade school carries with it norms and assumptions and its own set of values. In that way, it really is its own culture. A culture of children. We looked to older children for the clues about what's cool and how we should behave and what we should play. I remember looking up to the older grade school children when I was in first or second grade. They seemed so mature and so with it. It's hilarious to think back now, because they were only 10 years old! The culture of children exerts a strong influence. Suddenly, the child may start to care about the clothes the he wears to school, or the notebook that he takes to school. When I was in grade school, scratch-and-sniff stickers were a big deal. I'm guessing they're not so big now. But it was really important to have a sticker book, with an impressive display of all of your stickers. And there was this whole system of trading stickers. So if I had a brand-new sheet of pepperoni scratch-and-sniff stickers, and you had a brand-new sheet of bubblegum scratch-and-sniff stickers, we could trade and enhance each other's collections. A certain way of talking often becomes part of the culture as well, with the informal code of slang becoming important. It's a sign of fitting into the group that a child knows the special words or phrases approved by the culture of children. Everybody needs at least one close friend in grade school. Really, that's true well beyond the grade school years, but it's especially true in middle childhood. Friendship in middle childhood is more intense than it was in the preschool years. We don't demand much of our friends in preschool. We just need someone to play with and have fun with. It's not hard to make a new friend in preschool, but it's much harder to make new friends in grade school. We get pickier. We expect more. It's more upsetting when a friendship ends. And it's more important to us that our friends are similar to us in their interests. Some children emerge as popular, some are widely rejected, and the rest fall somewhere in between. Across the years, children's popularity among their peers often changes. This is good news because it means that just because a child had a very bad year doesn't mean he'll be rejected forever. And, what makes a child popular or unpopular anyway? Popular children tend to be children who have good social skills, although as we get older the overly confident and perhaps even arrogant kids also rise in social status. Many times there are two types of popular kids: the ones that everyone likes, and the ones that everyone is a little bit afraid of. The social skills that are necessary for being a good friend require social cognition, which is simply the ability to understand our experiences with each other and to imagine what someone else might be thinking or feeling. This means that we not only understand that others may have a different perspective than us, but also what their perspective is and how it may influence their behavior. Furthermore, we sometimes realize that our behavior can make a difference, or that we need to change our behavior to consider that other person's perspective or situation. If Jane has just started using her brand-new jump rope at recess, a child with a good sense of social cognition realizes that Jane is not going to want to let her borrow the jump rope right away. Jane just got that jump rope and she's excited and wants to use it for a while first, so the other child decides to wait and watch for a while, asking Jane if she can use it later. The idea of social cognition is not too terribly different from emotional intelligence. You could think of it as a very early form of emotional intelligence. But it certainly is important for building healthy friendships. Without social cognition skills, children make a lot of social mistakes. They might feel awkward and not know how to join a group. A girl may run right up to Jane and try to grab the jump rope away from her, not thinking about how Jane will respond. Or, let's say something accidental happens, and a boy bumps into another boy as they're lining up to go inside after recess. This kind of stuff happens all the time, right? If the one who got bumped interprets that interaction as "on purpose" and retaliates against the child who bumped him, that's a mistake in social cognition. Children who lack social cognition often jump to a very negative interpretation of others' behaviors, without considering how others' behaviors might have been influenced by other P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 8, p. 9 factors. The boy who bumped into him was just running too fast and didn't slow down soon enough. That's it. Children who tend to make these misinterpretations on a regular basis are children who are often rejected by the peer group. The culture of children collectively decides that they don't approve of this behavior. And remember, peers are less likely to sugarcoat things than our parents are. So the repercussions of these negative interactions can have devastating impacts on the child who lacks social cognition. Children are rejected for two main reasons. Some are rejected because of their aggressive behavior, like if the child who was bumped into turns around and slaps the other kid. Others are rejected because of their awkward or insecure behaviors, like if the child who was bumped into bursts into tears and starts whining about how nobody likes him. Not only do rejected children share that tendency to misinterpret events, but they also have problems regulating their emotions. These things can really take on a snowball effect unless someone intervenes to help the child. By the way, there's another group of children who aren't rejected, but are neglected. These are children who are basically ignored by the peer group, but they're not actively disliked. Neglected children tend to develop without much trouble. Sometimes they are just late bloomers when it comes to social skills, that they don't behave inappropriately but that they're very reserved and shy and keep to themselves. In terms of development, it's worse to be actively rejected than to be neglected. Both types of rejected children are at risk for becoming victims of bullying. Bullying involves repeated attacks on a person who doesn't have a social network or interpersonal skills to defend himself. These attacks are incredibly intentional; bullies are very skilled at identifying and targeting the rejected children. Most victims of bullying are withdrawn rejected children, but some are aggressive rejected children. These are bully victims, children who seem to want to start conflicts because they're so prone to take things very personally. They tend not to have any friends, and they tend not to have anyone who understands their situation. Bullying can be physical, verbal, or relational. The physical kind of bullying is obvious; it involves some kind of hitting, punching, or other physical violence. Verbal bullying is basically name-calling, and relational bullying is meant to harm a person's reputation by getting others to gang up on the individual or by spreading rumors or by instructing others not to be that child's friend. As we'll discuss later in the semester, technology has widened the arena for bullying. Verbal and relational bullying can now over the Internet and across cell phones. We call this cyber bullying. There is something to be done about bullying. If we can help that rejected child make at least one good friend, someone who will stick up for him or her, this can make a dramatic difference in the victim's life. The culture of the school matters as well, with schoolwide education regarding bullying and the participation of teachers. In some cases, teachers do not intervene when bullying is taking place. They may not even be fully aware that it's going on. Educating teachers on how to spot bullying and how to help stop it can make a big difference. Children can be taught how to intervene as well. Morality in Middle Childhood Children become really interested in right and wrong during the middle childhood years. Advances in social cognition certainly move this along, as do advances in concrete operational, logical thinking. It's interesting because in some ways children at this age show a sense of justice and morality that's even stronger, in some respects, than what you see in many adults. When it comes to ethnicity or religion, for example, children express greater tolerance than some adults do. It's different with gender, though. Even though children would tell you they think that it's wrong to discriminate because of gender, in their own behaviors they show extreme preference for same-sex friends. During the grade school years, children are very interested in playing with members of their own sex and not very interested at all in playing with opposite sex peers. They're pretty gender segregated, but not as much ethnically segregated. Lawrence Kohlberg was a psychologist who wanted to identify the different stages of moral development that we go through as we mature. His work was inspired by Piaget. Kohlberg found that morality was very P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 8, p. 10 self-centered in the years before grade school. We are more concerned about avoiding punishment and getting what we want. It makes sense if you think about how children are egocentric at this time. Their thinking about morality is very focused on their personal perspective. This is the preconventional stage of moral reasoning. Once we get into grade school, we lose our egocentrism, gain social cognition skills, and start to think more logically. With this comes an awareness that there are certain rules that are supposed to be followed. This is called the conventional stage of moral reasoning. Why do we behave in a moral way? We do so because we want to please others and gain their approval, or because we think it's important to follow the rules. It's a focus on the group and the norms of the group. There's another stage that comes after conventional moral reasoning, but why? Isn't there value in doing things that others accept? Isn't it important to follow the rules? Most of the time. But not all of the time. Think about the laws during Rosa Parks' time. She broke the law by refusing to give up her seat and move to the back of the bus. As adults, we understand the moral reasoning behind her decision even though she technically broke the law. In the postconventional stage of moral reasoning we move beyond the rigid notions of concrete operational thought and we understand that the rules are based on abstractions - like the abstract concept of justice. We think more about ideals in the postconventional stage of moral reasoning, considering principles over laws or rules. We understand that human beings make the laws, and that human beings sometimes fall short of the ideals. Furthermore, we understand that one's personal ethical values may conflict with those of the larger society as a whole. This is the idea that each individual has to decide his or her own values. In middle childhood, children move from preconventional to conventional moral reasoning. But not all adults make it to postconventional moral reasoning. It's interesting to see some adults still claiming that the laws are always the highest representation of our ideals. How would you determine what level of moral reasoning a person has reached? Kohlberg thought it was important to present someone with a moral dilemma and to carefully examine how they reason through that dilemma. It's not so important what decision they come to; it's more important how they came to that decision. Why did they come to that decision? The most famous scenario that's used to assess moral development is the Heinz dilemma, where a man named Heinz is struggling with a situation that doesn't have a clear solution. Heinz has a wife who is very very ill and who needs a drug in order to stay alive. There is a local druggist who has the drug that will keep Heinz's wife alive, but the druggist is selling it at a ridiculously high markup and will not budge on the price. So, Heinz breaks into the druggist's store and steals the drug. Did he do the right thing? It doesn't matter whether you think he did the right thing or not, in Kohlberg's view. What matters is the reasoning behind your decision. Were you focused on avoiding punishment or gaining approval? Were you focused primarily on the law or social norms? Or did your response consider the more basic principles of justice? Kohlberg's stages are useful way to think about different approaches to moral problems, but his work is not without criticism. His research was conducted only on boys, and he found that boys were more likely to reach the final stage stage 6 - than girls. But to assume that stage 6 is truly a higher level of moral reasoning stage 5 is questionable. For women and girls, relationships play a more central role in their moral reasoning. This may be why postconventional women are more likely to reason at stage 5 (which focuses more on interpersonal aspects of justice) and postconventional men are more likely to reason at stage 6 (which centers more on objective aspects of justice). It doesn't mean men are more moral than women, but it may indicate a bias in Kohlberg's definition of morality - a bias towards a more masculine definition of justice. We've reached the end of the grade school years, and we'll move next to discussing adolescence. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 1 EPISODE 9.1 – ADOLESCENCE: PHYSICAL DEVELOPMENT When you think of adolescence, what words and images and feelings come to mind? I think of words like "possibilities" and "excitement" and "confusion." But perhaps the most fitting word is "change." We experience phenomenal changes during adolescence, from the physical development of the body and brain, to changes in thinking, to the increasingly important world of friends surrounding us. In spite of all of this change, most adolescents are well-adjusted. Most adolescents still love their parents and feel close to them, even though they want to spend less and less time with them and more and more time with friends. We have a lot of changes to discuss, but in this episode we focus on the changes in the physical development of adolescents. Puberty Begins We make the physical transition from childhood to adulthood during puberty. Puberty begins a lot earlier than we realize because the first events are invisible, like the production of hormones. These days, hormone production increases around ages 9 or 9 1/2. It's a little bit later for boys and a little bit earlier for girls, which is the common adolescence experience - that girls develop faster than boys. Sex hormones get released once the gonads have developed. Gonads are sex glands, so that would be ovaries for girls and testes for boys. Girls' ovaries produce estradiol in adolescence at a rate of about eight times as much as in childhood. Boys' testes produce testosterone, about 18 times more in adolescence compared to childhood. By the way, girls also make testosterone and boys make estradiol, but they make far less of each. How does the body know when to make this happen? The HPA axis is involved. The hypothalamus, which is a structure in the brain, tells the pituitary gland, another structure in the brain, to make its hormones. The pituitary's hormones triggers the adrenal glans and the gonads. Let's discuss the adrenal glands first. The adrenal glands create the hormones epinephrine and norepinephrine, which are commonly referred to as stress hormones. These hormones influence growth, sleep, attitude, and other factors. Now, as I mentioned before, girls create testosterone and boys create estradiol. Where does this happen? The adrenal glands are responsible for this. So, boys' estradiol and girls' testosterone are released by the adrenal glands. What about the gonads? Well, the hypothalamus triggers the pituitary, and the pituitary triggers the development of the gonads. Then, the gonads create massive amounts of testosterone for boys and large amounts of estradiol for girls. Okay? After the gonads mature, girls start to ovulate. The uterus builds up a layer of lining in preparation for a possible pregnancy, and the girl has her first menstrual period somewhere around 12 1/2 years of age (on average). Menstruation is basically the result of the uterus shedding its lining. A girl's first menstrual period is called menarche. Boys have a similar experience whenever their testes develop to the extent that they can create sperm. The first time a boy ejaculates sperm is an event called spermarche; this often happens overnight during sleep in a wet dream (technically called a nocturnal emission). So there you have it – sexual maturity…at least in terms of the physical body. All of this talk about hormones and we haven't yet mentioned moods! Think about the attitude most people have about puberty and hormones. It's usually an attitude of fear and trepidation. How often have you heard someone talk about the raging hormones of P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 2 adolescents? How many times have you seen a movie where there's a teenager who is emotionally out of control? Be careful not to assume this is the reality for most teenagers. The research tells us that yes, our moods become more variable and changeable during adolescence. Yes, we are moodier than we were as children. Adolescents also experience some very new and powerful emotions, like lust - a big change from the childhood years. But, do hormones MAKE teenagers this way? Is it an inevitable outcome of this new increase in hormones? Hormones influence our behavior and our emotions, yes, but here's the part most people neglect: our behaviors and our emotions influence our hormone production as well. We are going through all kinds of changes, adjusting to how others are treating us differently, and trying out some new behaviors of our own. Just by itself, that's enough to get our emotions going, right? And as a result of these emotions, our production of hormones is affected. So, hormones influence our emotions, but our emotions also influence our hormones. Let's not perpetuate this myth that teenagers are controlled by hormones. Hormones influence sleep, too. It's funny how this topic gets relatively less attention than moods do. Obviously, sleep is incredibly important for any human being. I'm quite fond of sleep myself. But I remember being so very, very tired as a teenager, and I remember my friends going through the same thing. Parents might blame it on teenagers simply not getting to bed early enough. Sounds fair, right? I mean, I'd be curious to find out how many teenagers are online well into the night, into the wee hours of the morning, on Facebook or chatting or texting. We didn't have those things when I was a teenager, and I still had a hard time going to bed early. The research shows us that teenagers aren't getting enough sleep. There's a biological explanation for some of this, though, and it has to do with hormones. Our bodies are regulated by a number of circadian rhythms that reflect predictable changes in our hormone production across a 24-hour period. The pituitary gland produces hormones that actually shift the schedule of sleeprelated hormones for adolescents. Melatonin is a hormone that we need to help us sleep, and pituitary hormones delay the typical cycle of melatonin production. That's one reason why teenagers don't feel tired until after midnight. Yes, maybe they shouldn't be on Facebook until 3 AM, but it's unlikely they'll feel sleepy before midnight. So what we do? We start school at 8 AM. The day may begin even earlier if you're an athlete or in some extracurricular activity that involve before-school meetings or rehearsals. I remember having percussion ensemble practice at 6:45 or 7 AM. Let's do the math. Most teenagers aren't getting enough sleep, even if they go to bed right when they start to feel sleepy. Teenagers often go through the week with significant sleep deprivation, and then they try to catch up on their sleep over the weekends. They have probably had all kinds of different sleep schedules across the week, and maybe they've slept in until noon on Saturday and Sunday. It's going to be particularly difficult for them to go to bed and fall asleep at a reasonable time on Sunday night. Thus another week begins with significant sleep deprivation, and the pattern repeats itself! So what's the big deal? Sleep deprivation is part of our culture, isn't it? It's almost a badge of honor to complain about how little sleep you got last night. Well, It matters because sleep deprivation affects us more than we think. We don't learn as well when we are sleep deprived. We make riskier choices and we react more slowly while driving whenever we are sleep deprived. Even mild but chronic sleep deprivation can lead to depression, because when we deprive ourselves of sleep, we deprive our brains of the opportunity to rejuvenate overnight. Sleep deprived individuals have brains that aren't as P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 3 sensitive to neurotransmitters that help us feel alert, awake, and satisfied. Seems pretty clear what we need to do: Change our school schedule. Why can't school start later? If we were guided only by the research, we would make this change in the school schedule. But, as is often the case, many other factors impinge upon these kind of decisions. If we start school later, what will happen to our after school activities? How will teachers feel about this shift in their work schedule? Very few schools have attempted to change their schedules based on this research, so it appears that for the time being we are likely to have sleep deprived teenagers well into the future. That's too bad, because research tells us that teenagers at schools that start later show better outcomes in terms of both their academic and psychological functioning. The Timing of Puberty It's hard not to compare ourselves to others when it comes to the timing of puberty. Among girls in particular, there is a lot of talk about this very topic. Of course, with girls there's menarche, which is a very distinctive experience in a girl's life. Girls have to start paying attention to the calendar so they are prepared for when their next menstrual period may start. They have to leave class to go to the bathroom, or make sure to leave time in between classes to take care of things. And girls tend to disclose more to their girlfriends, so they all talk about when they're having their period. It's a big topic of conversation. It's kind of a bonding experience. The events of boys' puberty aren't as newsworthy among friends, perhaps because nocturnal emissions are very private and don't require any adjustments at school, and maybe also because boys don't disclose as much to their male friends. Still, boys are very aware of how they compare to their male peers in terms of height, weight, and tone of voice. Adolescents don't all experience puberty at the same time: some are very early and some are very late. Most of us are somewhere in the middle. Where does this variation in timing come from? A good portion of it is genetic. How young were your parents when they experienced puberty? That's a pretty good indication of the age at which you were likely to experience puberty. Genes also matter when it comes to sex differences. If you have sex chromosomes XY, you are a boy, and you are genetically predisposed to start the obvious, outward signs of puberty later than if you were a girl with sex chromosomes XX. Boys and girls are very similar in the timing of those early hormonal increases, like the adrenal gland activity around age 9. Girls are still ahead of boys on this, but only by a few months on average. The more obvious and outward signs are where the gender differences are most distinct, like the growth spurt and the changes in body proportions. Girls get taller and curvier much earlier than boys get taller and broader - about two years earlier, on average. Girls go through their growth spurt before menarche, which makes sense from an evolutionary perspective. It makes sense that a female would develop a body with adult-like proportions before being best suited to sustain a pregnancy. This means that the height spurt, the growth spurt, for girls happens in the middle of her puberty. For boys, the growth spurt happens much later, after spermarche. Again, think evolutionarily: males' contribution to pregnancy is simply sperm, so it doesn't matter that the rest of the body has not yet reached adult proportions. Body fat influences the timing of puberty as well, probably through its influence on hormones. Think about this from an evolutionary perspective. I know that we have negative attitudes about fat these days, and excessive fat is a real health risk. But when it comes to puberty, body fat is a signal that there is plenty of nourishment available for a P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 4 pregnancy. I mean, think back on what you learned about newborns: babies are born with excess body fat as an evolutionary strategy to enhance their survival. Okay, so now it probably makes sense that body fat signals to the rest of the body that puberty can happen. The more body fat we have, the earlier our puberty is likely to begin. The less body fat we have, the later our puberty is likely to begin. Think about a young professional gymnast, a teenage girl who has almost no body fat. She will likely have a menarche much later than other girls. Her body is not well suited to host a pregnancy. Some have wondered if the main culprit with food and today's relatively early puberty is hormonal additives in our foods. It's possible, but we don't yet have evidence of a direct link between hormonal additives and early puberty. However, we do have plenty of research that suggests these additives influence our appetites, which leads to greater body fat, which leads to earlier puberty. Also, our appetites in general increase in adolescence. For example, leptin is a hormone that increases our appetite, and our bodies begin to produce more leptin as we move from childhood to adolescence. This is clearest among girls - when estrogen decreases before a girl's period begins, leptin increases and appetite increases. The appetite increase from foods with additives and adolescents' naturally increasing appetites is the best explanation so far for early puberty. In certain areas of the world, children are malnourished and puberty is delayed. This provides more evidence for the association between body fat and puberty timing. We tend to forget that chronic malnutrition was a fact of life for most of human existence. Looking back across centuries of time, puberty has begun earlier and earlier as we became better and better nourished. We have also grown taller as a species over the centuries, thanks to better nutrition. This is called the secular trend, the finding that puberty begins much earlier today than it did in centuries past. Does this mean that eventually 5 year olds will be starting puberty? No. Research suggests that the secular trend has pretty much stopped in developed nations. The next finding may surprise you: The more stress a child experiences, the earlier his or her puberty is likely to begin. In other words, high stress correlates with early puberty. Where is this stress coming from? Harsh parenting practices, most likely. Harsh parenting generates a stressful atmosphere in the home, and this increases the production of sex hormones among the children in the family (especially girls). What's the evolutionary purpose? How might it be adaptive for girls in stressful environments to become sexually mature at an earlier age? Early puberty increases their odds of reproducing before they die. I know it sounds harsh and it's hard to imagine in today's world. I also think people get confused when we talk about evolutionary theory because they think about conscious thoughts and motivations. They think, "Well, I didn't want to get pregnant at the beginning of puberty, and nobody I knew would have wanted that either." That's right. But evolutionary influences are not conscious thought processes. It's about natural selection and the qualities that led to our ancestors' reproductive success. Your ancestors, way way back, were more likely to survive long enough to pass on their genes if, in a stressful environment, they were able to reproduce early. Let's say the environment was super stressful. A female entered puberty early, got pregnant, and gave birth. Now her genes have been passed on. Even if she doesn't survive, her genes live on in her offspring. This is reproductive success from an evolutionary perspective. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 5 Now, countless years later, thanks to natural selection, many of us have the predisposition to start puberty earlier when raised in a very stressful environment. Does it really matter to teenagers when puberty begins? It depends. We all like to talk about how unique we are, but the truth is that most of us in adolescence don't want to stick out as different from our friends. If we are off-time on puberty, on a different schedule than our peers, there are psychological consequences. But there are also sex differences. First of all, girls begin puberty earlier than boys, regardless of any other influence. So, a very early maturing girl is going through puberty before any of her peers–female or male. This isn't easy to handle, and early-maturing girls often have low self-esteem and high depression. These girls may find that they are treated better and get a lot of attention from older boys. This can seem great to the girl at the time because they have gained acceptance and it feels cool to have an older boyfriend. The problem is that that young girl is likely to be highly influenceable and may have sex before she's really ready, or may experiment with drugs or alcohol. Most of us aren't presented with the challenges until we are older and have more mature brains. Not so for the early developing girl. Girls who develop on time instead of early tend to have a healthier and happier adolescence. Boys also struggle with early maturation. In the historical past, early maturation was correlated with positive outcomes for boys, because others treated them greater respect. That's not the case so much today, where early maturing boys are more likely to become fathers, and teenage fathers show higher rates of psychological disorders like depression. It's difficult to be a late developer no matter which sex you are, but boys have it particularly tough. Think about the entire peer group. Girls show outward signs of puberty about two years earlier than boys on average. If you are a late-developing boy, you stand out because everybody else in your peer group is ahead of you. Late maturing boys are shorter and thinner and have higher pitched voices than all of the other boys. It can be tough on late developing girls, too, although it tends to be easier in respect to how the rest of the peer group is developing. Even if you're a late developing girl, chances are there still are quite a few boys who have not yet developed either. But kids of both sexes who are late developers show higher rates of self injury, like cutting. And cutting often indicates more serious underlying psychological problems. Nutrition Most adolescents are not getting the proper nutrition. I know I didn't. There were long stretches of time when breakfast for me was a Diet Coke and frosted doughnuts. It kind of makes me sick to think back on that. We drink much less milk today than we used to, and our teenage bodies are deficient in calcium as a result. Calcium is essential for the healthy development of bones, and our lack of calcium in adolescence may not become fully apparent until we become older adults and begin to have problems with osteoporosis and fragile bones. Most teenagers are deficient in iron as well, but for different reasons by sex. With menstruation, girls lose blood which reduces the amount of iron in their body. For boys, there's no connection with sperm or ejaculation and iron, but there is a connection between physical activity and iron. Boys are more physically active than girls, and their worn-out muscles require more iron in order to be able to grow. Persistent iron deficiency results in anemia, and guess what the main symptom of anemia is? Low energy. Combine this with schedules that don't match the sleep-related P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 6 hormonal cycles of adolescence, and it just makes so much sense why so many teenagers are falling asleep at school. We struggle with our body image during the teenage years, and this influences our decisions about what to eat. Most teenagers are unhappy with at least one of the changes puberty has brought to their bodies. There are cultural ideals as well, and teenagers are very aware of them. For boys, the cultural ideal for a masculine body is to be bigger and wider. Puberty for boys involves an increase in height and a broadening of the shoulders, so this often lines up with the cultural ideal. If anything, many teenage boys wish they weren't so thin, and they may compensate by lifting weights and trying to build muscle. The cultural ideal for a feminine body is to be thin, so the curves that come with female adolescence work against that ideal. Yes, female curves are valued by our culture, but the curves are accompanied by increases in body fat in general for most teenage girls. Some girls see a little bit of fat and assume that they need to lose weight. They may start to cut down on their calories, which will undoubtedly affect the balance of nutrients they are getting. Taken to an extreme, this can lead to eating disorders. Rates of eating disorders increase greatly in adolescence, especially among teenage girls. Anorexia nervosa is an eating disorder where a person basically starves herself. She is convinced that she's fat, and that's what she sees when she looks in the mirror. The perception of her own body is extremely distorted and she denies that she has a problem. Everyone else sees that she's getting too skinny. Everyone else is worried. But, when she looks in the mirror, all she sees is fat. When we don't get proper nutrition over an extended period of time, we wear our bodies down. Our vital organs need nutrients to be able to function. Sadly, anorexia can go so far that the individual dies from organ failure. Bulimia nervosa is a different kind of eating disorder, although the underlying distorted body perception is there. People with bulimia nervosa go on binges, eating massive amounts of food all at once. She feel like she has no control over this behavior. After binging, she purges–forcing herself to throw up what she just ate, or using laxatives to get rid of the food. It can be tricky to spot bulimia because the individual may not look all that different. Her body size and shape is often very similar to the average person. But bulimia nervosa can have dramatically negative impacts on the body, like problems with the digestive system and the heart. Where do eating disorders come from? There is evidence of genetic influences; for example, you may see patterns of anorexia in a given family. Severe depression also correlates with anorexia, so there may be some type of similar underlying genetic influence going on. Developing in puberty can be a trigger for some people, as they become very concerned about body image and try new diets. Think of how leptin increases moving into adolescence–this surge in appetite could lead to an episode of binging, which the teenager deals with by purging. Once she's done it one time, it gets easier and easier to keep doing it. Parents may have an influence as well. If parents have been extremely restrictive in controlling the child's eating over the years, this could impact the child's view of food as something they want to take control of. It becomes more about control than anything else. Interestingly, parents can have a positive impact as well by encouraging regular family meals. It isn't quite clear exactly how this influence works, but children who have been raised in a family where there were regular family P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 7 meals–and that means that everybody in the family sits down and eats at the same time on a regular basis–these children show a lower risk of eating disorders. Of course, the regular family dinners may also be an indication of a close-knit family that functions well in a number of other ways. So it's not that the family dinner all by itself prevent eating disorders, but it may reflect a family cohesion that serves as a buffer - to protect against all the risks of developing eating disorders. Sexual Behavior There are two types of sexual characteristics that change during puberty: primary sex characteristics and secondary sex characteristics. Primary sex characteristics are changes to the sex organs that are necessary to be able to reproduce. To be able to make a baby, a number of organs are absolutely required: ovaries and uterus, testes and a penis. The hormones produced during adolescence trigger the growth of these organs. Secondary sex characteristics are sex-related body changes that are not directly involved in reproduction. A woman doesn't have to have a curvy body in order to reproduce. Her hips and her breasts are sex-related changes–secondary sex characteristics–that make her look more womanly, but are not directly involved in reproduction. For boys, the widening of the shoulders and the deepening of the voice are two examples of secondary sex characteristics. The body is changing, becoming sexually mature, and hormones influence thoughts and desires about sex as well. It's a risky time in the lifespan, and it's a risky time from a historical perspective for a number of reasons. More teenagers today than ever before have some kind of sexually transmitted infection. Puberty starts earlier, and we have more accepting attitude about sex today than in the past. These two influences together can lead to sex at younger and younger ages, which is correlated with negative psychological outcomes like depression. Teenage pregnancy is an obvious risk as well. If teenage pregnancy occurs, it's very unlikely that the teenage mother will be married. It's also likely–more likely than before–that the new grandmother (the maternal grandmother) is working full time and isn't as available to pitch in the with childrearing as grandmothers of the past. Finally, it's more expensive and challenging to raise children in today's world, a stress that most parents feel, but a stress particularly overwhelming for a teenage parent who is not yet psychologically mature. It's interesting -- Teenagers are having more sex and are having sex earlier, but there are fewer teen pregnancies today than in the past. Adolescents have learned about birth control and are using it more often than teenagers of the past. But, among those teenagers who do become pregnant, the youngest are at greatest risk for every type of complication associated with pregnancy. This could be because the youngest teens are the least likely to get early prenatal care, and because their bodies are not yet ready to manage the physical stress of pregnancy. Teenage pregnancy is more likely to progress in a healthy manner among girls age 15 or older. Although the physical risks are lower, the psychological consequences are still often overwhelming. Psychological problems like insecure attachment occur at higher rates for teenage mothers and children of teenage mothers, and both teen moms and their children are less likely to complete their education. Teenagers are at great risk of sexually transmitted infections, even though they're doing a better job of using contraception than past generations. Obviously, not all birth control P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 8 protects against sexually transmitted infections. Once again, the youngest teenagers are the most vulnerable. Immunity against STIs increases with age, and young teenagers– especially girls–don't have their biological defenses fully built up yet. If they're exposed to the STI, they are highly likely to develop it. For years, scientists have been aware of the potentially dangerous effects of STIs like chlamydia, which is the most common one. Lately, there's been much more attention and concern directed toward HPV (human papillomavirus). This one is particularly scary because there are no obvious signs of the infection at first, but the virus increases the chances of girls developing uterine cancer later in life. And this could be decades later. HPV can also cause genital warts in both sexes, although the warts may not appear for months or years afterwards. Teens may think they're protected if they use condoms during intercourse, but HPV can spread through simple genital contact. The high risk of being infected with HPV has lead to the development of a vaccine to protect children before they become sexually active, although there is plenty of controversy over whether this is the best approach to the problem. That wraps up our coverage of the physical changes of adolescent development. In the next episode, we will discuss the development of the brain and cognition during this time in the lifespan. EPISODE 9.2: ADOLESCENCE: THE DEVELOPMENT OF THE BRAIN AND COGNITION What were you thinking? Did anyone ever ask you this when you were a teenager? Most of us made some pretty questionable decisions as teens. But, at the same time, our thinking as teenagers was much more complex than it was when we were children. We became capable of amazing feats of cognition. So it's a mix: teenagers have more complex thoughts than children, but their thinking is also highly influenceable, especially when emotions are involved. Brain Development The brain is always developing. Even when you are 80 years old, your brain will still be developing. But there are certain times in the lifespan when brain development is particularly rapid, or when certain changes are most likely to occur. And adolescence is one of those times. Remember the prefrontal cortex? This is a part of the brain near the front of the frontal lobes that is very slow to develop across the lifespan. It helps us regulate our emotions and control our impulses, largely by calming down the activity of the emotional centers in our brain. The prefrontal cortex has developed enough by the time we are in grade school so that we can manage to sit still for a period of time. It has developed by five years of age so that we no longer throw the same intense tantrums we did as two-year-olds. Well, this development – a very gradual development – continues into adolescence, and scientists think the prefrontal cortex reaches maturity around the age of 25. But guess which area of the brain is fully developed by adolescence? The emotional center - the limbic system. One important structure of the limbic system is the amygdala, which processes emotions. The hormones of puberty make the amygdala more sensitive and responsive, which leaves teens feeling very intense emotions. With an immature prefrontal cortex and a highly responsive limbic system, it is quite a challenge for teenagers to regulate emotions and control their impulses. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 9 Research shows us that teens are capable of making very logical decisions. But, when we ask teenagers to participate in research, and we describe a scenario to them in order to test their reasoning ability, we are not triggering their emotional impulses. It's a very neutral experience for them with little or no involvement from the limbic system. In contrast, what decisions will they make when surrounded by friends? The pressure of the social situation combined with a very sensitive and reactive amygdala may overwhelm the fledgling attempts of the immature prefrontal cortex. It's like the activity of the limbic system prevents the prefrontal cortex from doing its job. In the moment, the desire to belong or be accepted or act on impulse wins, and teens make some questionable decisions. Logical, deliberate reasoning is a speciality of the prefrontal cortex. It's immature during these years, so it's clear how real life situations in adolescence can lead teens to do things they later regret. Furthermore, the charge that they get from these intense impulses and emotions feels pretty good to teenagers. It's more exciting and attractive in the moment than cold, hard logic. Another development during the teenage years is a burst of myelination. Remember, myelin is the coating that helps speed communication between neurons; because of the increase in adolescence, teens have very rapid reactions and responses. The brain is rather plastic (changeable) at this time, very responsive to experience. This may give adolescents the courage to try something new, or to push themselves to the limit in their chosen activities. I remember being able to practice musical instruments for countless hours. I was a percussionist and I played snare drum in marching band; my favorite instrument otherwise was the marimba, which is similar to a xylophone. It's true that I was tired a lot of the time (hello, shifted circadian rhythms and early school!), but I was still able to quickly learn and benefit from practicing over and over again. Once we develop into adulthood, especially past early adulthood, brain plasticity decreases. It's important that teenagers have opportunities and encouragement to take advantage of this burst of myelination and plasticity. Thinking about Oneself We care a lot about what people think of us in adolescence, even if we sometimes pretend that we don't. The research clearly shows that most of us are a little insecure and want to check with our friends to make certain we fit in. There's also a lot of introspection during this time, thinking about yourself. Adolescents are egocentric, but it's a different kind of egocentrism than the early childhood variety. As teenagers, egocentrism comes out in our extreme concern about what everybody else is thinking about us and our conviction that others are thinking about us a lot. Were pretty sensitive during this time as well. If it's all about me, then I'm likely to pick up on any of your behaviors as an indication of something directed toward me… instead of the more likely possibility that your behavior has more to do with you than me. If you seem to blow me off and hardly say anything to me one day, I may take that as a personal insult. It happens with positive interactions, too, when things are going well. If someone compliments you, as a teenager you are more likely to allow this to inflate your sense of self-importance, at least in the moment. In either direction, it's an intense response fueled by egocentrism. We engage in some irrational beliefs as adolescence as well, such as the personal fable and the invincibility fable. The personal fable is an irrational belief that my life is so unique and so special, and that I am destined to have amazing experiences because of this. It's an exaggeration of the specialness or the uniqueness of our experiences. If a teenage girl tells her mother, "You can't possibly understand what it P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 10 feels like for me, now that Billy broke up with me!" Well, in fact, mom may have gone through her own heartbreak as a teenager, but her daughter is convinced that this breakup she is going through right now is so completely unique that nobody could possibly understand…that her experience is much more difficult than anyone else's, including (and perhaps especially) her mother's. The invincibility fable is another product of adolescent egocentrism, but this one can be very dangerous for adolescents. The invincibility fable is an irrational belief that I am not vulnerable to the risks in life. A 16year-old boy may be well aware that it's unsafe to drive above the speed limit, but in his mind he's a much better driver than everyone else, so he thinks he is immune to the risk himself. It's the idea that the risks don't apply to me. And finally, adolescence often brings with it a sense of having an imaginary audience. This is the egocentric belief that other people are very much aware of the details of my appearance and my behaviors, which can lead a person to become consumed with worry about what everybody else is thinking about them. You feel like the spotlight is on you, like everybody is watching and noticing everything about you. This reflects egocentrism because we think we are much more important in the eyes of everyone else then we really are. The truth is that all of the other adolescents are also worried that you're noticing everything about them. I find it really funny today to think back on how much I was concerned about my appearance, whether my clothes matched or my bangs were properly feathered (I'm dating myself here), when everyone else was having similar worries of their own. Formal Operational Thought I have a question for you. If you could have a third eye and you could put it anywhere, where would you put it and what could it do? This question was asked of grade school children and teenagers, and the results demonstrated clear cognitive differences. Grade school kids thought the question was kind of dumb because nobody really could ever have a third eye. It was common for grade school children to say that they would put their third eye between their other two eyes, and that it could let them see really well. Teenagers have more fun answering this question. One said he'd put his third eye on his hand so he could find the biggest cookie when he reached into the cookie jar. Another said he would put his third eye on top of a tuft of his hair on his head, and that it could rotate 360° so he could see all around him from way up high. They enjoyed this task and asked if they could do things like this more in the future. The difference isn't just creativity. The difference is between concrete, reality-based thinking and hypothetical, abstract thinking. Grade school children were limited because they view the world very concretely, very much steeped in reality and what they've experienced before. Adolescents are gaining formal operational skills, as Piaget would refer to them, and one of those skills is abstract thinking. Teenagers can think not only about what they've experienced in the past, but also about things they've never experienced. Furthermore, they can imagine consequences and think through the possibilities of situations that have never occurred before, and may never occur. Nobody has a third eye. Nobody is ever going to offer a third eye to you that you could put anywhere you please, that could do anything you please. It's completely hypothetical. Nevertheless, adolescents can apply their logical thinking skills to the third eye scenario - an imaginary situation, whereas grade schoolers get hung up on reality. Adolescents can think logically, develop hypotheses, and imagine how hypotheses could be tested. To hypothesize means to predict what's going to happen in the future, in a situation or within the context of a problem you haven't encountered before. Piaget P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 11 developed a number of experiments to test formal operational thinking. These experiments would involve imagining outcomes and systematically testing a prediction. Teenagers do this better than grade school children. For example, the balance scale task involves making predictions about how a scale will react when you put different sized weights on it at different distances from the center. Grade school kids will try to solve the problem, but they aren't systematic about it. Their approach is haphazard, based on trial and error. In contrast, adolescents are more likely to develop a hypothesis–a prediction about the factors that will result in balancing the scale. Based on their prediction, they will then systematically try out combinations related to their hypothesis. These same skills come out in more creative or open ended questions that require "what if" propositions, imagining possibilities like in the third eye task. Interestingly, all of this focus on possibilities can result to rigid, idealistic thinking. Teenagers are very aware of ideals - the way things could be, and the way things should be. They may start to think about the way their parents raised them and the rules that they have to follow right now, and imagine how those rules and how their parents could be different. They imagine, "What if my curfew was much later? What is the worst thing that could happen? Why couldn't my curfew be later?" Another reason for these changes has to do with the difference between inductive and deductive reasoning. In grade school, most of us focused on inductive reasoning, using concrete examples to come to general conclusions about things. We move from what we perceive to be concrete examples to making general conclusions. Let's say that a boy has a number of negative interactions with girls. He thinks about those six girls who have been mean to him this year, and he concludes that "Girls are mean!" The concrete examples from the past lead to a generalized conclusion. Deductive reasoning works in the other direction, from the top down…from a general principle to specific predictions. A teenager may conclude that "Girls are mean," and test his prediction by noticing whether this generality is supported by specific examples. We do become capable of formal operational thinking in adolescence, but our skills of cold, hard logic may fail us in the moment when the limbic system is functioning at full force. But let's not overlook the fact that even adults struggle between logical thinking (which is more analytical) and intuitive thinking (which is based more on what feels right). When people say, "It was a gut-level decision," they're talking about intuitive thought. The trouble with intuition is that it often feels right or feels better, even when it's wrong. We have assumptions based on our past experience and we tend to be less critical thinkers than we should be. Once we've made an intuitive decision, it's very difficult to get us to change our minds because we become invested in defending our choice. So, it should not surprise us that teenagers rely on their intuition more than they should and use their formal operational skills unevenly and inconsistently. As adults, thankfully, our limbic system can be held in check better by our more mature prefrontal cortex, but we've all experienced the strain of trying to remain logical in the midst of having intuitive or gut-level feelings about something. This isn't to say that intuition is always incorrect. Sometimes your gut is correct. But it certainly fails us at times, and we are unlikely to be fully aware or to fully admit when this is the case. That's the danger. And there's often divide between parents and their teenage children when it comes to understanding each other's perspectives. Parents place the highest value on teenagers' health and well-being over the long term, but adolescents are geared more to value social connection and acceptance in the moment. It's especially telling when adults are P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 12 able to think back on the priorities they had as teenagers and some the things they valued at that time – like taking risks, trying new things, and feeling things very strongly. Parents may become overly concerned about protecting their children and forgetting what it was like to be a young formal operational thinker with a strong limbic system and powerful gut feelings. Of course, as adults we arguably have the superior prefrontal cortex in this scenario, but simply telling adolescents how they should behave doesn't have much of an influence when the teenager is faced with a situation in the moment that they must deal with. And, a heavy-handed approach of trying to control teenage children can backfire and harm communication in the relationship, which could do even more damage to the teenager's development in the long run than their immature prefrontal cortex could do. Teaching and Learning School is such a focal context for development, and secondary education brings with it a new set of challenges and opportunities. The first part of secondary education, usually grades six through eight, is often referred to as middle school. In the past, it was more common that just seventh and eighth graders would be together in the school, and it was then called junior high. Recently there has been a switch to more middle schools and fewer junior high schools. Middle school is a difficult time for many adolescents, partially because the early years of adolescence are a time of very rapid and distinct change. Unfortunately, for many kids it's a time when academic achievement decreases, and behavioral problems increase. Class sizes are often larger than in grade school, which means that each child is getting less attention from their teacher than they are used to. They are now interacting with a bunch of new people, most of whom are older, and it's tough to figure out how to fit in. And bullying persists, especially relational bullying. Relational bullies tend to become more admired in middle school than before. Furthermore, it's not so cool in middle school to be a good student anymore, and this obviously impacts motivation to study and pay attention during class. Adolescent egocentrism insures that most teens would rather deal with lower grades if it meant greater acceptance from peers. What we have here in middle school may be a disconnect between the needs of early adolescence and the emphasis of the school environment. The tools of learning have increased with technology, as computers and other digital devices are increasingly used in school. We used to have a so-called digital divide, a gap between groups of people in terms of their computer use, with the different sexes and different income levels. Technology use among teens used to be the territory of boys and children from more affluent families. Today, in nations like ours, a large proportion of children have used technology as a learning tool. But what exactly are they using it for? That's a different question. Yes, they are using technology and the Internet to learn, but the questions they seek to answer online are not always related to school. Many turn to the Internet to learn about topics they feel they can't talk about with their parents, like sex. Software helps students learn; use of word processing software in particular is related to improvement in reading skills. There's a great potential to use computers and the Internet to trigger collaborative projects among students, where students discover high-quality sources and information, and collaborate to create a new idea or product. And what about their social relationships? Technology is certainly playing a larger role in this area of life than before. For me, social relationships were maintained through conversations in the hallway between classes, notes passed during P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 13 class, and phone calls after school. But today, teens have many more options for staying in touch with friends, and today's teenagers are making use of all of this technology. They use their cell phones to text each other, their computers to IM each other or update each other on Facebook, and their cell phones to talk to each other on the phone. So far, the research suggests that all of this social contact is a good thing, enhancing social relationships on the whole. Indeed, the majority of teenagers are not loners hiding behind their computers, afraid of face-to-face interaction. They are communicating faceto-face at school, but they are communicating a lot outside of school or in addition to their face-to-face time as well. Also, imagine the benefit that electronic communication might bring for the egocentric, emotionally intense adolescent. It doesn't matter what your hair looks like if you're just texting or posting on Facebook. You can think about what you're going to say, or even pause and wait to respond, over technological communication devices much more easily than if you're standing face-to-face with another person. Of course, when conflict, controversy, or embarrassment erupt thanks to technology, things can take a dramatically negative turn, as recent tragic stories in the news have made abundantly clear. At Rutgers University, for example, Tyler Clementi committed suicide after his roommate secretly captured and streamed live video of Tyler having a romantic interaction with another student in his dorm room. Were they purposefully trying to harm Tyler's reputation, to victimize him in some way? Tyler certainly seemed to take it that way, although their intent isn't clear. When we broadcast information about other people, sharing private information intended to harm the victim in some way, this is called cyberbullying. Even if the bully is posting from his or her own account, with the identity being very clear, the act of doing something online feels more anonymous than doing it face-to-face. It's easier to insult someone from behind a computer screen then when you are facing each other. I have to tell you, I'm very glad that Facebook came into existence when I was already in my 30s. Yes, I can imagine how great it would've been to keep in touch with my friends, but I can easily imagine the potentially embarrassing and stressful effects of cyberbullying. Do you think technology makes the sting of bullying more painful now than in the past? Or is this bullying just the same bullying young people have always had to contend with, except that today's teens have new technological tools to assist them in their bullying? This is a current controversy in the field. Entering a New School Transitions are difficult for all of us, at any age in the lifespan, but they are particularly challenging for adolescents who already trying hard to manage the normative changes of adolescence. It's tough to adjust when we go to a new school, whether we do so because our parents moved, or whether we are simply going from grade school, to middle school, to high school. That first year at the new school tends to bring with it significant challenges, and with it we see an increase in psychological problems and a decrease in academic achievement. It's important to strengthen a child's support network to help buffer against the stress of these changes. For example, consider immigrant teenagers who are dealing with a move to a new country, learning a new language, and adjusting to new friends. Their success is enhanced if they attend a school specifically designed for new immigrant students, because they have an instant support group of people going through the same experiences at the same time. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 14 What are we teaching in our high schools? There's an obvious answer to that question and a not-so-obvious answer. Obviously, at school teens learn about subjects, like history, math, and science. But they also pick up more subtle lessons about what our schools value, based on the opportunities that are provided. This can shape teens' attitudes and motivations. Some students feel like they never fit in, and their needs may get lost in the shuffle. For example, our high schools are designed primarily for college preparation, with classes that emphasize building skills of formal operational thinking. What about students who arrive in high school without a basic understanding of this mode of thinking? Such students can be quickly left behind. Perhaps some would rather prefer to take a vocational route, learning a trade that they can apply in the workforce. Maybe they are not interested in the types of careers that require a college education. Vocational programs were once more common in the United States, even with opportunities for students to earn credit for on-the-job experience off campus during school hours. Those programs are rare today. Instead, we now have higher academic requirements – more classes required in math, science, history, and English. Some schools even require a foreign language. There is not enough time in the day for outside opportunities or vocational training, if all students must fulfill these academic requirements. Adding to this pressure, some states require students to pass a highstakes test in order to be able to graduate. This is in addition to successfully completing all of their courses. You can imagine the level of stress this generates, and maybe some of you have had the experience of taking a high-stakes test. Obviously, the original goal of high-stakes testing was to improve achievement and ensure that academic standards are met. This is a noble goal. However, high-stakes tests have a side effect of making teachers and students so focused on the test that learning is constrained to the information that will be on the test. Students who excel at academic subjects and seek careers that require college education may benefit from our current high school system, but what about the others? What do they lose from being in a system that doesn't match their values and goals? As I mentioned, there are fewer opportunities for students who might prefer a more vocational focus in high school. Some of these students become frustrated and discouraged by the college-bound focus of high school, so much so that they drop out. If these students have had more opportunity to develop their interest in skills, perhaps in apprenticeships with local businesses, they may have learned more in high school and have been prepared for better jobs upon graduation. But it's not so simple. It depends greatly upon the current job market and upon the willingness of local businesses to participate in such a program. Besides, how much can a student learn about a vocation or a trade during the high school years? Most of us learn the most while working on the job, after we've been hired. I learned important information during my schooling, but I have learned invaluable lessons about teaching during nearly a decade on the job – lessons I never could have learned as a student alone. So we should not romanticize the idea of vocational education, assuming that non-college-bound students would be fully prepared for professions upon graduation. But a change in the high school curriculum, or at least increased options for different pathways of those not interested in academics, might help all students stay engaged and motivated enough to learn skills that help anyone master any job – critical thinking skills and communication skills. No matter which career we choose, we need to know how to think, we need to know how to communicate our thoughts in writing and in speech, and we need to learn how best to interact with others. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 15 But just how many students graduate high school? How many drop out? Interestingly, this is not a straightforward question to answer, although you would think it should be. The stats look particularly bad if we simply calculate the percentage of ninth graders who graduate four years later. Using this calculation, more than 50% of ninth graders in Los Angeles drop out. But what if it simply took them longer than four years to finish? What if they left school, but came back and finished later? What if they completed their GED later? None of these are counted in the statistic. We can look at a different calculation, that of status dropouts. The status dropout calculation is the percentage of 18 to 24year-olds who have completed high school. This allows a more generous window of time to account for irregular paths through high school, taking longer to finish for whatever reason. The results look much better by this measure, but they show us that certain ethnicities–like Hispanics–have considerably higher rates of noncompletion than other ethnicities. So, what are the factors that might contribute to the non-completion of high school? It's not about intelligence. It's more about engagement. So then the question becomes, why are so many students disengaging from the school experience? Perhaps it has to do with the more narrow focus of school these days, as high-stakes testing and budget cuts lead to trimming down extracurricular opportunities and after school programs, both of which have been shown in past research to increase student engagement. It may have something to do with what we value in teachers and how we prepare teachers for the classroom. In the United States, we focus teacher training on content knowledge. We emphasize content expertise, and that's obviously important. Believe me, you wouldn't want me teaching you physics. I know nothing about it. It doesn't matter how engaging I am if I don't understand the subject, right? But perhaps we gone too far in our focus on expertise, ignoring the qualities and skills that help teachers become particularly engaging. Learning is not just about content. The learning atmosphere matters as well. So, what can we do to improve our high schools? We can't simply eliminate math and science, or history and English. Academics are an important part of education. Nevertheless, research does highlight changes that have the potential to make a big difference in the lives of students. Let's deal with sleep deprivation, the chronic lack of sleep so typical among today's teenagers. In the few schools that now start later as a result of the research on adolescent sleep patterns, students are performing better, getting sick less often, and participating more actively during class. Let's bring more attention back to extracurricular activities. It's true they aren't the most important thing in school, but that doesn't mean that they are useless. Students who get involved in extracurricular activities are more invested in their high school experience. They are healthier mentally, they are less likely to get in trouble, and they earn higher grades. If extracurriculars aren't readily available at the school, community-based activities–like those sponsored by religious institutions or other community groups - are also related to positive development and engagement among students. In this case, what matters the most is that students' interests and talents are valued somewhere. Let's provide students with more attention, and keep them from getting lost in the crowd. Research tells us that it's best if high schools are large enough school so that there are numerous activities and opportunities, but not so large that students get lost. We can increase students' sense of belonging through the use of learning clusters, where the same group of teachers instructs the same group of students. It's like a built in community within the school. This approach pays attention to the importance of social interaction as a P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 9, p. 16 motivator for students. And finally, let's ensure that students feel safe at school. It's interesting, because some of the things that schools have done in the hopes of increasing a sense of security have backfired, like using metal detectors. These kinds of changes increase students' fear, which can paradoxically create a more tense environment where violence is more likely to occur. If we create learning clusters and keep our schools to a manageable size, emphasize extracurricular or community involvement, these changes can foster a healthier school climate where harassment and violence are less likely to occur. There is no such thing as the perfect high school or perfect secondary education. All across the world, there educators struggle to keep students engaged. But let's allow the knowledge gained from careful and replicated research to be our guide for making improvements. And let's conduct more research to learn additional strategies to help teenagers develop their potential. All of the biological and cognitive developments we've just discussed occur in a very dynamic, exciting, and sometimes overwhelming and frightening psychosocial context. That is the focus of the next podcast on adolescence. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 10, p. 1 EPISODE 10.1: ADOLESENCE – IDENTITY AND RELATIONSHIPS WITH FAMILY AND FRIENDS The adolescent years - ages 12 to 18 - are a very active time for the exploration of psychosocial issues. In this episode, we focus on two big topics in psychosocial development: Identity and relationships with family and friends. Identity Identity development begins in adolescence, but it doesnʼt end in adolescence…at least, not today. Most teenagers today are actively and anxiously exploring their options: what team or club to join, which college to attend, how to dress, how to behave… All of this exploration is good, at least according to Erikson. He believed that we must explore all of our options before we can truly figure out our identity - reaching identity achievement, in his terms. Adolescence marks the beginning of that exploration. I suspect that many of you are in your 20s, though, and you still feel like you still have a long way to go. That's normal. Welcome to the 21st century! That's the way it tends to be these days, but more on that in the next chapter on emerging adulthood. So, back to adolescence and identity development. Erikson called this stage identity vs. role confusion, and he thought this was a time of stress and challenge where we really are concerned about figuring out who we are. There are three different ways that Erikson and researchers after him believed that we cope with this challenge: role confusion, foreclosure, and moratorium. None of these captures identity achievement yet, but these are all steps that might come before we reach identity achievement. Role confusion is also called identity diffusion, and it is basically the worst way to handle the crisis of adolescence, in terms of psychological outcomes. Adolescents who are trying to avoid doing any exploration or thinking about their future are those identified as role confused (or identity diffused). It's like theyʼre hoping that all of this identity business will just somehow go away. They are not interested in thinking about it. They may feel hopeless, they may become withdrawn, or they may choose to identify themselves with a peer group instead of going through the task of figuring out their own individual identity. Another option is foreclosure. Foreclosure occurs when adolescents make decisions about what they're going to do with their life and who they are, but they make these decisions before any real exploration has even occurred. They foreclose early on identity development, without having explored. What usually happens is that the foreclosed adolescent takes on the goals, values, or wishes of their parents or their culture as their own, without giving other options a try. Now, let me clarify: A person could end up choosing a lot of the same values and beliefs of their parents, but Erikson would say that's not true identity development unless the adolescent had at first considered other options - had gone through the work of actually thinking about what they would want for themselves. So, it's not about the decision that they come to in the end; it's more about the process. And foreclosure is a process of deciding early and without any kind of exploration. Moratorium is a period of exploration, but it's a period of exploration that's ongoing, meaning that we've not yet made decisions at that time. College is kind of becoming the new moratorium for development because the goal of it is that you spend time there, you have certain classes that you're required to take for breadth requirements, and you eventually pick a major and you P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 10, p. 2 start to focus in. The breadth requirements - the idea behind them, in fact - make you have an exposure to different kinds of topics you might not normally have considered. So, it can be a way of providing a moratorium. But vocational development and career choices and college majors…that's just one component of identity (which is called vocational identity). There are many other kinds of identity as well, and you'll see exploration during moratorium in those areas, too - trying out different styles of dress, different hairstyles, different ways of behaving. Ideally, moratorium helps us examine our options and helps us make decisions about our goals for the future. It is a step toward identity achievement. But, in reality, teenagers may bounce back and forth between different ways of coping with identity vs. role confusion. Perhaps they start out with a very active and assertive period of moratorium, really trying things out. And then they get tired and frustrated, feel like giving up for a while and enter a period of role-confusion. Maybe finally that starts to feel bad and they may go back to moratorium and they may move on to identity achievement later. Or they may start out foreclosed but have some sort of experience or come to some realizations that trigger a moratorium where they realize, “Oh, wait a second. I havenʼt come to a decision yet on these things.” So there isnʼt one path through this and many adolescents have kind of a jagged path. Thatʼs normal. Whatʼs also normal is that most of us these days do not feel like weʼve really come to an overall sense of identity achievement until sometime in our 20s. Now identity occurs in four basic areas. I think people are accustomed to focusing on vocational identity. You vocational identity is a big focus, something we start bugging kids about even before they are teenagers, with questions like "What do you want to be when you grow up?" In high school and college, the stress can feel overwhelming. I have met countless students who are stressed out because they're not sure what they want to be in terms of a career or vocation…but they feel intense pressure to figure it out really soon and get through school as soon as possible. Our parents have a strong influence on our thinking, but the focus that they tend to take during the vocational identity development process is more on "don't repeat the mistakes I made." In other words, parent when theyʼre trying to help with vocational identity tend to focus more on instructing their kids what not to do, instead of what to do. Teenagers do have job experiences. Many teens have some kind of part-time job. And you might think on-the-job experience will help them figure out the kinds of things theyʼd like to do with their vocational future Thatʼs not necessarily the case. Research shows us that teens, especially those who work over 20 hours a week, have an even harder time with identity development, perhaps because they must spend so much of their "exploration years" stuck at a job, and the jobs available at this level for teenagers are often not stimulating and very rarely motivating. Itʼs also a challenge to come to some final decision about career development when the reality of todayʼs work world indicates that we need to be ready to make changes in our careers across the lifespan. Thatʼs what the world of work is requiring of us these days. No longer can we just choose one occupation and stay there for life, as our grandparents might have done or our great-grandparents might have done. It is stressful, the idea of you have to be prepared for change but more of us will be working careers that require more cognitively stimulating activities, like working with knowledge and using our communication skills. And thatʼs why communication our ideas – in writing and speaking and evaluating information – all of those skills are so critical to success in the work force today. And they are skills that transfer from one P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 10, p. 3 job to another. Another aspect of identity is gender identity. This is an area of development that has changed a lot in recent years, as attitudes about gender and sexual orientation are diversifying. There are fewer rigid notions about what is appropriate for females and males, and what is acceptable in terms of sexual orientation. Gender identity is our personal sense of being male or female, and it usually matches the biological sex we were born with. But this isn't always the case, with a small portion of individuals, they may have a gender identity that is the opposite sex of their physical body- technically that is the case with transsexuals – their gender identity is one sex but their physical body is the other. Youʼll often hear such individuals say things like, “Iʼve never felt like a boy.” You know, they have a boyʼs body but theyʼve always felt like a girl in their minds as their identity. For most of us though, obviously, the two line up – that gender identity matches biological sex. In the teenage years, the hormones that come with puberty definitely create new feelings of sexual attraction. There are many variations among teens in regards to strength of sexual urges, and in the direction of desires (straight, gay, or bisexual), and how much a teen acts on or hides his or her sexual urges. Some teens may not be aware of their true desires until they get a little older. Sexual orientation refers to whom one is sexual attracted, with heterosexuals sexually interested in the opposite sex, homosexuals in the same sex, and bisexuals in both sexes. There is exploration in sexual identity, even more so today than in the past. There is a lot of flux and thatʼs becoming more acceptable, especially among peers. A 12-year-old with homosexual attractions may or may not become a homosexual adult. However, it is advisable for a parent to avoid saying things like, “Oh Iʼm sure that your homosexual attraction is just a phase,” because when parents say things like this, it gives teens a sense that they won't be fully accepted unless they are heterosexual. The concerns and anxieties that come with that may result in the teenager foreclosing on a gender identity to be in line with parents' wishes. A girl sexually attracted to another girl may decide to push those urges away and pretend to be heterosexual so that she is accepted by her parents. But thereʼs still a risk even if the teen decides to remain open about her sexual orientation. Because if she is still attracted to females but she knows her parents donʼt really accept it, this can result in significant strain in the parent-teen relationship and it can also influence the psychological well-being of the teenager. Religious identity is a third vector of identity development and this is something that many individuals donʼt really achieve until adulthood, but many teenagers are really interested in thinking and talking about different religious and spiritual beliefs (this makes sense because of formal operational thinking and adolescentʼs increased ability to imagine possibilities and think through situations). A small portion of adolescents become devout members of their parents' religion. Outsiders might view this as a form of foreclosure, deciding before doing much exploration but it maybe too early to tell. Firm religious belief may last a lifetime for some of these teens. For others, it will have been a phase of foreclosure, followed by some moratorium and then perhaps an identity achievement later on. Maybe a teenager stays in a state of moratorium, sort of exploring their options and not coming to final decisions on the matter. Maybe that person will become an agnostic as an adult, which basically means that they aren't sure what they believe in terms of religion. A number of different routes and destinations are possible. Regardless of the end point that someone comes to in terms of their religious beliefs or their spiritual ideas, one clear sign of mature, religious identity is feeling so comfortable about one's own beliefs that others' different beliefs are not threatening. It's a live and let live thing. Clinging so forcibly to oneʼs personal faith that one must demonize or pity others for being P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 10, p. 4 "wrong" suggests foreclosed religious identity in terms of Eriksonʼs theory. Finally, the fourth component of identity is political and ethnic identity. Most teenagers donʼt adopt a strong political identity because itʼs just not a salient issue for most teenagers and this is true worldwide. Politics tend not to take center stage for teenagers. Among those who are interested in politics, most teenagers are identifying lately as independent politically, interested more in the person whoʼs running for office then in affiliating with one party or another. In contrast to political identity, ethnic identity tends to have a stronger impact these days. In fact, ethnic identity and ethnicity, in general, can influence political views. Teens today tend not to identify with a party, then form their values – instead, they form their values which are often inspired by their ethnicity, and thatʼs likely to trigger their political beliefs. This is called identity politics. But what about the general understanding of cultural background and how to weave that into the mainstream culture of America. Thatʼs ethnic identity development. And it begins in early adolescents and extends throughout the teenage years. But it often continues to morph and evolve further across the lifespan, because historical or societal changes may trigger ethnic identity adjustments - this was probably the case for many Americans of Middle Eastern descent after 911 because they were suddenly much more salient for their ethnic identity then they have been before largely due to the stereotypes that others in America held towards them because of their appearance or because of their religious belief. A Middle-Eastern woman in her forties might not have struggled much with ethnic identity or might have felt pretty secure with it until she became a target of discrimination after 911, which could then trigger more consideration of ethnic identity issues. If ethnicity is significantly intertwined with religion, that can make ethnic identity development a more salient issue, even for teenagers. It also plays a role in relationships and other life decisions, such as the decision whether to stay near family or move away for opportunities. Family and Friends Everyone knows that our family is less important in adolescence than before, right? Wrong. It's definitely true that friends become more important than they have ever been before, but it's healthy for teens to stay connected to their family as well. As odd as it may seem, the bickering that is common between parents and kids at this time is actually one sign of continued attachment. It's a signal that the relationship needs adjusting and that both members are interested in some kind of resolution. Here's a common scenario: the teen starts making more of his own decisions, and the parents get angry that he decides not to come to Sunday dinner. Bickering occurs, and perhaps continues for quite some time. The parents may be worried that their son is going to start drinking or end up in jail if they don't have as close of a watch over him. Theyʼre worried about the people heʼs hanging out with. Theyʼre worried that heʼs driving on the freeways so much, and so on. Bickering continues. Eventually, parents and their son establish some kind of compromise, and they say they can accept it, lets say in this case, if their son makes it to at least one Sunday dinner a month. As a result, he has earned more autonomy, and the parentteen relationship has adapted successfully. Mom, Dad, and son tend to feel closer after they have resolved this conflict. But you could guess which kind of parenting makes this scenario most likely: authoritative parenting. Remember that? Authoritative parents place a premium on communication so that if P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 10, p. 5 the child has a difference of opinion or has reason to present as to why things should be different, the parents allow their child to voice his or her ideas. It doesnʼt mean that the child is in charge. No the parent is still the ultimate authority, but you can imagine how growing in such a family would prepare a family well for the teenage years when negotiations are made even more frequently and become even more important. But some teens donʼt seem to care what parents think. What if parents assume it's a good thing to just distance themselves and let their teen go free? This can be dangerous and lead to neglect, and the effects may not be obvious at first. Teens often do seem to disengage, especially when they feel their parents arenʼt interested in them. Itʼs important for parents not to be fooled by that exterior appearance of the teen not caring. Even if teens act like they don't need their parents or care about their parents, the research shows us that they care deeply, in fact, about what their parents think and whether their parents care for them and accept them. Teenagers can get very good at hiding how much they care, but it's very clear thatʼs thereʼs a strong correlation between the quality of the parent-teen relationship and adolescent selfesteem. Parents still matter, no matter what. Remember how annoyed you would get when your parents needed to hear all of the details about where you were going, who you'd be with, when you'd be home, etc…? They were doing their job as parental monitors. It sounds oppressive, but the impact of parental monitoring depends upon the family context. If the family relationships have been harmonious, the parental monitoring of adolescence is helpful and is associated with less risky behavior among teens. This is not the case when the parent-teen relationship is centered on parental control - or even psychological control, which is the worst. With psychological control, parents use guilt as a weapon to control their teen. How do they do this? They threaten to withdraw support, or they somehow indicate that they love the teen less because of what has happened (or if something bad happens in the future). As a result, teens may feel so guilty and indebted to their parents that they remain overly dependent and close to their parent, but it's of a fear of losing the parent's love (even though this fear that they have is not always conscious for the teenager). So, perfect parents: What do they do? They allow their teens just the right amount of freedom monitoring them appropriately but not excessively, and making sure never to manipulate or induce guilt. Right? No parent is perfect, and all families hit rough patches along the way. In many families it's a game of constant adjustment and re-evaluation, with many parents worrying if theyʼre doing enough monitoring or not enough monitoring all the while. Although family is important, it is true that friends become very salient in the lives of adolescents – becoming more important to teens then ever before in development. Friendships exist at different levels within larger social networks – there are cliques and there are crowds. These are groups the teenagers form on their own, and these groups may morph and change over time. Cliques are small groups of relatively close friends. The members know each other well and spend a lot of time together. Crowds, on the other hand, are larger social groups of teenagers who are affiliated in some way, like they may be of the same ethnicity, they may be involved in the same school activities like band or athletics, or the smart bookish kids referred to by others as "the nerds" or "the brains" or whatever they are calling them these days. Of course, over time, the names change. A teen's affiliation with a crowd is usually pretty informal and kind of loose – but the people in that teen's clique are far more central to their everyday life and far more influential in their development. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 10, p. 6 It's really normal for parents to worry that their child's friends and to be concern that there will be peer pressure and peers will have a negative influence on their child. That can certainly happen, but it's definitely more of the exception and than it is the norm. For most teens, they do feel peer pressure but itʼs peer pressure towards positive, encouraged being healthy and/or wise behavior. In other words, itʼs pressure towards the good stuff. Pressure towards things that arenʼt harmful. I remember my friends peer pressuring me when I wanted to quit band in 8th grade. They knew how much I loved music and how much I loved being a musician and they were worried I'd regret the decision. And also worried because they wanted us all to spend time together as we moved into high school band. It was definitely peer pressure, but not towards any kind of dangerous or questionable behavior. So what about the exception - when peers have a negative influence on a teenager? It's referred to as deviancy training. Sounds pretty formal, right? Well, deviancy training is when one teen helps instruct the other on how to break the rules - maybe how to skip class without getting noticed, how to sneak alcohol into a basketball game, or how to break into the school to vandalize school property. Deviancy training certainly occurs, but most teens do not take it to an extreme. Encouraging one another to skip a class is less of an offense, I think we would all agree, than encouraging violence or vandalism or other behaviors that fit under the category of juvenile delinquency. Also, teens tend to select peers who are similar to themselves. A student with a history of troubled behavior, who enjoys vandalizing and getting in trouble, is unlikely to seek out the friendship of a straight-laced classmate. Like attracts like. Birds of a feather flock together. In fact, studies of juvenile delinquency reform programs indicate that it can be risky to group offenders together because what happens is that they often trade ideas and tips for how to continue their delinquent behavior – basically helping each other become more deviant which is obviously the opposite of what was intended. There are certain features of the American immigrant experience that relate specifically to the role of peers in adolescence. Itʼs interesting because compared to same-ethnicity peers born in the U.S., immigrant youth tend to show higher levels of success and well-being during the teenage years. Why might this be the case? I mean, you might expect that immigrant teens would have a lot of trouble or a lot of challenges with the balancing their native culture and their new American culture. And it is a challenge, especially when the two cultures conflict on views about things like how much time teenagers should spend with their family versus there friends, and how important autonomy and independence is compared to family cohesion and connectedness. Nevertheless, immigrant teens are often given more adult responsibilities, especially if they are an English-speaking bridge between their parents and American society. And this can help teens develop a sense of responsibility and feel value as a member within their family. There is a balance to strike, though. If teens are required to spend most of their time in the service of their family, that obviously means less time is left to spend on school, activities, and friends and other aspects of adolescence that are critical to the individualʼs own development. The research suggests, though, that most immigrant youth and their families handle these challenges very well. And having peers who are going through similar experiences, other teenage friends who are also immigrant youth, helps greatly. This extends to teenagers of all backgrounds, by the way. Teenagers need close friends who have gone through experiences similar to themselves. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 10, p. 7 EPISODE 10.2 ADOLESCENCE - SEXUALITY AND PSYCHOLOGICAL ADJUSTMENT In this episode on psychosocial development in adolescence, we discuss sexuality and mental health. Sexuality Remember what you thought about dating and kissing and romance when you were in grade school. Most of us thought that was kind of gross. We were not interested in sexuality then, and we're not interested in the opposite sex. Girls and boys routinely make fun of one another, each claiming superiority over the other. But somehow, most of us end up in adulthood with very clear interests in romantic relationships. What happens in between - during the adolescent years - is highly variable, influenced not only by individual factors, but also by contextual factors like culture, ethnicity, and history. Adolescence is a high drama time for romance, with relationships forming and ending, usually in rapid succession, all within the view of the larger crowd of peers. The private experience of dealing with new sexual feelings – like the thoughts and urges and worries inside teens' heads could also lead to secrecy, shame, confusion, and feelings of isolation. Many teens think that others just wouldn't understand what is going on in their minds, but the truth is that lots of teens feel this way. For homosexual teens, adolescence is particularly challenging. Some may choose to date opposite-sex peers, just in an attempt to fit in. Others may not even realize how much they are repressing their sexual urges - it might not be until later that they finally have the conscious awareness that they are homosexual. Even though things are improving with better attitudes and acceptance in the United States for homosexuality and for just variation in sexual orientation in general, teens still may have to contend with conflicting views that come from their parents, culture, or religious background. It's hard to know how many teenagers identify as homosexual or bisexual, maybe because teens may admit to same-sex attraction but not feel the need to adopt the identity of one orientation. In fact, most teens who admit such feelings and interests become heterosexual adults. it's hard to know for sure, but research suggests that same-sex experimentation isn't unusual and that, for some, it is simply experimentation. For others, it's the beginning of what will be their stable sexual orientation identity. If you ask homosexual adults when they first realized their sexual orientation, you see gender differences. Men remember knowing earlier but they often do not tell until they are a little bit older in adolescence. So many gay men, looking back at having feelings of attraction and realizing they were gay in adolescence but waiting for later in adolescence to actually admit it. For women, most adult lesbians remember coming to the realization of their orientation more after adolescence than during adolescence. By the way, we sometimes act like all of this questioning and wondering and not knowing whatʼs going to happen is just something that teens with samesex feelings go through, but thatʼs not true. This confusion and not quite knowing what to think is common for all teens when it comes to sexual behavior and sexual interest. I mean, letʼs remember that heterosexual teens also change their minds, they end relationships, get swept up quickly in a new one, they feel confused, and aren't sure about things either. So are we really all that different? Probably not. How much do teenagers really understand about sex? This is a question behind many of the concerns of the sex education. Sex education varies by state here in the United States, and some teens may learn all that they know from their peers or from early romantic partners (or the P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 10, p. 8 internet). Teens are very interested in the sexual experiences of their friends, and it can sometimes become a salient factor within a clique. While parents would probably be happy to hear that their child hangs out with other "proud virgins", this lack of sexual activity is not paired with a thorough education in sex. In other words, abstaining from sex doesnʼt necessarily mean that adolescents have a full understanding of the ways sex can be dangerous. For example, itʼs probably true that a lot of parents would feel relaxed and be happy to hear that their teenager may hang out with other “proud virgins” and agreed to not have sex during high school. But if you follow these individuals as researchers have, and look at their activity after high school, after it all many of them decide to not be virgins anymore and to become sexually active. We donʼt see lower rates of sexually transmitted infections or lower rates of pregnancy amongst those who were sex-free in high school. The bottom line is no matter the teenagerʼs sexual behavior, teenagers need to have a good understanding of sexual behavior and the risks that come with it and the ways in which to protect themselves. Most teenagers who are in romantic relationships are most likely to be sexually active. They actually learn from each other through experimentation, but their overly-active limbic systems (and their relative immature pre-frontal cortexes) can get in the way of a very careful discussion of how to protect themselves against STIs and pregnancy. When theyʼre caught up in the moment and passionate assurances might be made like "you're the only one" or "I'll just pull out, and you won't get pregnant" may seem perfectly acceptable, again in the moment, but that maybe the limbic system overpowering the pre-frontal cortex and later on reflecting on their decisions, they may become really nervous and worried and understand the risk they have taken whenever their pre-frontal cortex is not bombarded with the excitement of the limbic system. So what role can parents really play in educating teenagers about sex? Well, the research tells us their role will be far more influential if they start well before their kids are romantically involved. The trouble is, many parents don't realize how romantically involved their kids have already become. Parents may be afraid of starting the conversation too early. They may push it off thinking, “Oh, I donʼt want to open up this conversation. What if talking about it encourages my child.” But in reality that might be exactly when the child needs it the most. And parents may not realize what an example they set for their teenage children as well. When single parents are dating and having sexual relationships, this correlates with earlier sexual behavior among their teenage children. Does sexual education belong in our schools though? According to developmental scientists, the answer is a clear yes. Ideally, though, experts would like conversations to happen between parents and their teen as well. The issue of sex education in our schools is a significant controversy in the United States, where there is great variety in sex education from state to state, especially when it comes to the details of safe sex and contraception. In some states, they may prefer abstinence only education, which encourages teenagers to avoid sex entirely. Usually no information is provided about contraception or about avoiding pregnancy in abstinence programs. The fear is that if itʼs talked about, that would be an encouragement for teenagers to start having sex. Research indicates that these programs are ineffective, because sexual behavior and use of contraception is about the same regardless of whether teens had sex education or abstinence-only education. In other words, the research shows us that in the states that follow an abstinence only program, it doesnʼt correlate in differences in the sexual behavior and use of contraception of the teenagers who live there. And a growing body of research tells us that it's most effective to start sex education earlier - perhaps in 9th grade - P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 10, p. 9 before most teens have had sex for the first time. How much sex are teens having? The majority of teens have had sex by the age of 16. Ages and rates of sexual behavior are very similar across developed nations, although American teens use less contraception. This can explain our much higher rates of teenage pregnancy then in other developed nations. Although the controversy about exactly how and when to teach teenagers about sex will continue to rage, it does seem clear that itʼs important to somehow get this information to teenagers in the hopes that it will increase their use of contraception and encourage safe sex to avoid STIs. Most will keep the baby, and most will not marry the father. Most will not choose adoption. Psychological Adjustment In movies and in the media, we see lots of teens struggling with pretty significant psychological problems. This can give off the false impression that the teenage years are a time of significant psychological turmoil. But research tells us that most teens are functioning quite well, both mentally and physically. In fact, only about 20% of adolescents have some kind of disorder that negatively impacts their development. Of course, it's quite common for teenagers to have spells of sadness that are difficult, but not overwhelming – you know, periods where they feel hopeless, fatigued, or insecure for a few days or so. They may even stop doing some of the things they usually love to do, like playing a sport or shopping with friends. Nevertheless, the disorder clinical depression is a diagnosis thatʼs reserved for significant depressive symptoms that last for at least 2-3 weeks, solid. What does this feel like, this clinical depression? Imagine the fatigue of jet lag mixed with the sadness of grief over a lost loved one. And then you have some idea of what a depressive episode, an episode of clinical depression feels like. Teens of both sexes experience a decrease in self-esteem in adolescence, yet rates of depression are far higher for girls than for boys. Actually, 2Xs as many girls as boys have clinical depression during adolescence. With any type of psychological disorder, there are always multiple possible influences. Like genes. Genes matter. Some of us are predisposed to depression. Environment matters, too - especially parenting, and especially mom's mental health. But still, why the gender difference? There are probably a number of reasons, but one that has been investigated in great detail involves thought patterns. Girls are more likely than boys to "get stuck" in a negative thought pattern, going over and over a situation, a conversation, an experience that was upsetting to them. Itʼs like theyʼre reliving the experience over and over. It's a way of coping, but it can also descend into clinical depression. This habit of a repetitive focus on negative thoughts is called rumination. Boys are much less likely than girls to ruminate. But they get stressed and upset, too, so what do they do? They are more likely to act out when upset, sometimes becoming aggressive in response or turning to substances as an escape. In fact, some experts think that boys actually show similar levels of depression, but that it comes out in a different way. That they keep these thoughts private by shutting others out and not talking about it. The much higher rates of substance abuse, delinquency, and suicide among boys suggests that their persistent negative emotions just come out in a different way. Contrary to popular misconception, suicide is not more common in adolescence than in other times in the lifespan. Suicide is actually most likely to occur during older adulthood, in fact, and most often among men. But, suicidal ideation - which refers to thinking about suicide - is more common during the teenage years. It's just that most who think about it don't actually do it. Or some may try, but do not succeed, which is called a parasuicide. Parasuicides are when a P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 10, p. 10 person engages in purposeful activity that could have ended his life, but doesn't. Paracides are much more common than completed suicides, where the teen actually does take his own life. When suicide happens in adolescence, we must be careful not to over-glorify the deceased person because this can inadvertently encourage other vulnerable teens to kill themselves, resulting in so-called cluster suicides. This actually happened in my hometown, and it was very shocking and devastating for our small community. How about anger? Most adolescents have an angry outburst every once in awhile, but most teens manage their anger pretty well. A small portion of adolescents, predominantly boys, have strong and persistent aggressive urges than can lead, eventually, to juvenile delinquency. Of those who break the law, only a small portion are apprehended, and a small portion of those apprehended are actually arrested. Most offenders are male, and most are African-American. Note that this refers to those who are actually arrested. The confidential self-report data from teens tells us that there are many teens of other ethnicities and gender who break the law, but are not arrested for whatever reason. By the way, with all of this talk about male aggression, I feel the need to clarify that girls are also capable of great aggression - but their aggression tends to be relational instead of physical. This behavior, this relational aggression, isn't likely to land girls in jail, but it can do plenty of damage to others along the way by turning peers against another girl or boy or spreading rumors to ruin someoneʼs reputation. In regards to adolescence who show a great deal of aggression, one of our biggest concerns is whether it will last into adulthood. Some teenagers outgrow their antisocial tendencies, and experts refer to these as adolescence-limited offenders. Their law breaking is influenced more by their multiple contexts - like their friends and their neighborhood - and their behavior are less influenced by the offender's biology, some kind of predisposition towards aggression. Oftentimes, these offenders hang out in groups, committing crimes with the encouragement of their friends. The challenge is to try and prevent that teen from the changes that could come as a result of their law-breaking that could escalate into a lifetime of crime - changes like early parenthood or dropping out of school, for example. A close relationship with parents or another important adult can make a big difference. Some aggressive and antisocial teenagers who are in the habit of breaking the law do not outgrow these tendencies and scientist refer to these as life-course-persistent offenders. Their profile differs significantly from that of the adolescencelimited offenders. Itʼs associated more with biology, like neurological problems, brain related problems than it is associated with environmental factors. These offenders show signs of antisocial behavior even before adolescence, and their behavior continues across the lifespan as well. Still, even with these neurological influences, life-course-persistent offenders can change if support relationships with family or with others in the community are made during adolescence. This is especially important because life-course offenders tend to be loners those who don't have anyone they can really talk to. Weʼve talked about misconceptions regarding psychological health of adolescence and misconceptions are common when it comes to teens and their use of drugs. In fact, one assumption is that most teenagers are regular drug users. That's not what confidential reports from teens tell us. In fact, American teens' use of drugs has actually declined in the last 30 years. Now, do adolescents experiment with drugs, not necessarily becoming regular users? Yes, many do this. But most do not become regular users. And most regular users are boys, which may again show us gender differences in how teens cope with negative emotions. Regardless of gender, teens at greatest risk for becoming addicted are those who started using drugs in early adolescence. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 10, p. 11 Any regular use during adolescence at all, though, can result in serious long-term harm. Letʼs start with marijuana for example. We talk a lot of marijuana today in the press and how it results in fewer problems than alcohol for example. There arenʼt many people who have car accidents when theyʼre high but there are lots of people who have car accidents when theyʼre drunk, right? So itʼs very salient to us but letʼs not make the mistake of underestimating the impact that marijuana use and particularly regular marijuana use can have on adolescences. With regular use, marijuana can impair adolescentʼs memory. It can reduce their motivation and it can get in the way of their language learning. And all of these things can have a big impact if you think about how important these skills are for success at school and success in activities and how that leads to future activities and success. So with regular use of marijuana, a teenager may become apathetic about things, not caring so much anymore. And this can have a big impact on their future plans. Smoking, whether itʼs cigarettes, or some other form of tobacco, one of the biggest risks of regular use is stunted growth. When people smoke their appetite is reduced and they donʼt eat as much. As a result, most smokers are not getting the nutrients that their body really needs and our bodies are still growing during adolescence. Tobacco, then, interferes with the growth of the body during adolescence. And of course alcohol. I think most of us already knew that alcohol relates to brain damage. People always talk about alcohol killing brain cells, but they usually donʼt get into the specifics. The specific areas are parts of the brain that are directly related to learning, and emotional regulation and decision making. The hippocampus and the prefrontal cortex are the two spots where the damage of alcohol consumption is most likely to occur. And this results in lots of impairments like trouble with thinking, trouble controlling impulses, and difficulty with memory. Also, things can really become a cycle with alcohol use because teens may turn to alcohol because alcohol makes them forget about their worries. But then all that time they spend drinking usually creates more problems in their real lives and so now they have even bigger problems and they feel even more compelled to drink, to forget it all. And the cycle continues. No matter which psychoactive drug a teen takes, any drug that has an impact on our mind and our thinking is called a psychoactive drug, all one big brain impact in common: they trigger the limbic system and impair prefrontal cortex. This is basically making the adolescent brain even more immature than it is in its natural state, which leads to increased chances of poor decisions and risky behaviors in the future. So what do we do to discourage teenagers from using drugs? Good question. Itʼs difficult because this brain weʼve been talking about with the immature prefrontal cortex and active limbic system makes the idea of using drugs for teenagers very exciting. Remember, itʼs control of impulses - its one of the big challenges because of this uneven brain development. Also, teens often underestimate the extent of their drug use, and they often think that adults, and their parents in particular, are way too uptight about the dangers of drug use. So, somehow, the warnings of parents don't seem to have much of an impact on the average teen, perhaps because of generational forgetting – this is the idea that each youth cohort learns its lessons on its own, assuming that their parents don't really understand and are out of touch. Teens also assume that their friends are the group to listen to when it comes to drug use. Many educational programs and advertising campaigns have resulted in basically no change in drug P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 10, p. 12 use, and some ads have been found to actually increase drug use. Maybe because they make it seem more exciting and even more appealing to that active limbic system. However, there are some success stories that can be built upon. Ads targeted more toward teens' perspectives sometimes have a stronger impact, but it is really difficult to capture this aesthetic just right. Contextual factors matter, too, like the economy (cigarettes are expensive) and also parents' behavior. For example, parents who model responsible behavior with their own use of substances tend to have kids less likely to become regular users. With all of this talk in the last 25 minutes or so about the risk and the dangers and all of the things parents really hope donʼt happen to their teenagers, letʼs not forget that most teenagers do not have significant psychological or physical or drug-use related problems during this time, thank goodness. P16 Podcast Transcript, Amy Himsel, Ph.D. C hapter 11, p. 1 EPISODE 11.0 – Emerging Adulthood We are finally talking about emerging adulthood. This is one of my favorite sections of the lifespan because of everything that is going on and how interesting it a ll can b e. Sometimes p eople refer to emerging adulthood as young adulthood or as youth. As far as a ge goes, we’re talking about years 18-­‐ 25. And it’s only now that textbooks are b eginning to include a separate chapter to talk about these years. We used to either mention this s tuff at the end of adolescence or talk about it a t the b eginning of a chapter on early adulthood or young adulthood. But many changes have taken p lace over a gradual period of years that have extended the p eriod of time between adolescence and entering the basic roles of adulthood. We’re getting married later. We’re b ecoming parents later. We’re getting more education. We are more financially d ependent upon our parents during this stage. And we a lso have a lot of questions and concerns and uncertainties related to our vocation and our vocational identity. This results in a p eriod of time full of exploration and instability. Things seem to b e in constant flux which can be exhilarating, but a lso terrifying and exhausting. Physical Development Most emerging adults are pretty h ealthy from the ages of 18-­‐25. It’s a time when chronic d iseases are really rare and our immune s ystem is functioning at p eak levels. And even for people who’ve had diseases during childhood, like asthma for example, will often notice that their s ymptoms b egin to lessen and even disappear b y the time they reach the age of 18. But our bodies are made up of systems and these systems are dynamic. Each body s ystem influences the other body s ystems. One thing that helps during emerging adulthood is that most p eople h ave a pretty active lifestyle. Emerging adults tend to b e more physically active than other adult age groups. And that kind of a ctivity influences the function of the cardiovascular s ystem. And then when the cardiovascular s ystem is functioning well, that enhances the functioning of brains. But as a college professor, I spend a lot of time with emerging a dults and p lenty of them are doing lots of things that are unhealthy. S leep d eprivation is the first that comes to mind. So how does it make sense that we’re at our p eak functioning in emerging a dulthood when at the same time lots of emerging adults have pretty bad habits. Well, you can thank homeostasis. Homeostasis is the body’s a bility to maintain a steady, internal state – it’s the process of the body wanting to go back to its steady, internal state. So when we’re hot, we a chieve homeostasis b y s weating and releasing some of the moisture in our body onto our skin so that the air p icks it up and a ctually cools off the body. But in emerging adulthood, this a djustment occurs really rapidly, and that is one reason why most emerging adults are healthy, even though they put themselves through quite a lot of stress, q uite a lot of sleep d eprivation, and quite a lot of drinking and partying and other kinds of activities. They get s ick, yes. But they get better faster. They recover from their illnesses faster. It can b e tricky, though, b ecause emerging adults can get the s ense that they are inevitable, that they can bounce back from anything. In the meantime, they might b e overlooking some of the gradual damages that they’re doing to themselves. So just b ecause you can manage to make it through a few days or a week or a p eriod of time where you’ve had all kinds of s leep d eprivation and all kinds of crazy variations in s leep schedules, that d oesn’t mean that the body is managing just fine. It could b e, and it often is the case, that there is damage going on, it just might not show up until later. For example, chronic sleep d eprivation may b e something you feel you can manage in emerging adulthood, but it’s correlated with more rapid, physical a ging, for example. Something that is happening gradually but won’t b ecome n oticeable until the p erson is older, maybe closer to 40. The physical body is operating at its p eak in terms of sex and reproduction, which creates an interesting disconnect for a lot of emerging P16 Podcast Transcript, Amy Himsel, Ph.D. C hapter 11, p. 2 adults b ecause most of them don’t want to get pregnant during this stage of their life. But sexual responsiveness is high and pregnancy is more likely to occur. Women are more fertile during this time than they will b e later. And women who get pregnant and give b irth recover from b irth more quickly. Infertility is very rare. But, like I said, most emerging a dults want to wait until later to get married and start a family. That means that emerging adults have this p eriod of time during which the s ex they are having, if they are having s ex, is p urely recreational. And that means n ot intended to produce children. And may involve multiple partners b ecause they are n ot ready to commit to marriage yet. And that is one of the reasons why there is an increasing risk of getting a sexually transmitted infection. In emerging adulthood, about 50% of people have a t least one s exually transmitted infection. You may think, “Well, those must b e the promiscuous ones, the ones that are having s ex with a ll kinds of different p eople.” Not n ecessarily. In emerging adulthood, s erial monogamy is very common. That just means that p eople tend to have one long-­‐term relationship followed b y another long-­‐term relationship. Long-­‐term may not mean years and years. It could b e a series of months. But the point is most emerging adults aren’t terribly promiscuous, but they d o have a lot of relationships one after the other. And few emerging adults allow enough time in between their s exual partners to thoroughly test themselves for STIs. So then they can unknowingly pass their STIs to other, or expose themselves to infections. Everybody knows the risk of HIV and how scary that particular STI is. But a lot of p eople don’t realize the incredibly h igh risk of HPV, which is an S TI we talked a bout earlier that can b e passed not only through intercourse b ut a lso through genital contact. People d on’t even have to have sex to pass HPV back and forth. This is a risk of b eing s exually active during this p eriod of time. On the topic of risks, emerging adults a ctually have quite an appetite for risk taking. And this is refer to as edgework. Think of edgework as living off the edge, having an interest in adventure, having an interest in taking risks. The risky adventures, the ones where d eath could happen, are the most exhilarating for many emerging adults. Of course, p ersonality is going to make a difference. But even among the more reserved and conservative among us, when they were emerging adults they were probably more willing to take risks than they are as older adults. Jobs that involve risks are more appealing to emerging adults than to other stages of the lifespan. And this is true of hobbies and activities as well, like extreme sports. Risks are also taken in the realm of drinking and drug a buse. Drug use b ecomes drug abuse when it escalates to the p oint where the p erson is making d ecisions that cause him or her physical or cognitive or psychological harm. Then it’s drug abuse. If a substance is abuse long enough, then addiction could follow. And that’s when a p erson b ecomes p hysically d ependent on a substance. When they s top using the substance, they have withdrawal s ymptoms. The truth is that a s mall proportion of emerging adults will b ecome addicts. But a lot of other emerging adults will drink h eavily. And even though they may not become addicted, they do open themselves up to lots of risks in the process. It’s interesting if you look at the data b ecause drinking and drug use are most common among emerging adults who come from relatively well-­‐off backgrounds, like financially stable b ackgrounds and among those who are successful in school. Maybe this is b ecause these are the people most likely to be in college and college itself is a context where a lot of drinking and substance use happens. In particular, b inge drinking is a problem on college campuses. Binge drinking is when a p erson consumes a large a mount of a lcohol in a very short period of time, maybe pounding down a whole bunch of shots. And this is a phenomenon that’s unfortunately all too common a t colleges. Because of their love of risks, b ecause of their urge to use drugs, and sometimes b ecause of a combination of those two things, emerging adults are at a h igh risk of violent d eath. The leading causes P16 Podcast Transcript, Amy Himsel, Ph.D. C hapter 11, p. 3 of death a mong 15-­‐30 year olds are accidents, suicides, and h omicides. I still remember the shock I felt when I was in college, called home and talked to my mom to find out that a h igh school classmate of mine had died in his 20s as he was trying to get a way from a p olice officer who was pursuing h im for his drunk driving. He crashed into a n embankment and h e died. The willingness to take risks combined with lots of alcohol abuse, in this case, turned out to have a tragic result. There is a gender d ifference though in terms of the risk of violent d eath. Young women are far less likely than young men to d ie this way. So how can we reduce the kinds of harmful, risky b ehaviors? How can we reduce the a mount of binge drinking on campuses? Part of the problem s eems to b e about p erception versus reality. It turns out that college students overestimate h ow much their friends are drinking, and how much their friends are smoking cigarettes, and how much their friends are doing illegal drugs. When you a ctually measure and assess how much of this substance use is going on, and you show it to college s tudents, they’re surprised that there is less of this a ctivity than they thought. And the research shows us so far that finding out that you’ve been overestimating h ow much everybody else is doing leads to a d ecrease in the amount of h eavy drinking a t least, a t many colleges. I mean, everybody would probably understand it if we said that your friends influence how much you drink, but isn’t it interesting to find out that it’s actually your own individual p erception of how much your friends drink that s eems to play a bigger role rather than objectively how much your friends drink. Cognitive Maturity The last time we talked about cognitive development, we d iscussed formal operational thinking, which involves the ability to reason about a bstract concepts, to come up with ideas, to imagine possibilities, to engage in h ypothetical and d eductive reasoning. But there’s a lot more to thinking in real life than b eing able to solve logic problems, of course. You can do a great job with logic puzzles, in a philosophy course, for example, but could have a lot of problems understanding more complex issues like cultural differences that come up as you’re taking an anthropology course in college. Thinking in adulthood becomes more flexible and more practical. This involves b eing a ble to accept u ncertainties, to manage emotions, and to balance the a ctivity of the more intuitive and emotional limbic system with the more logical, prefrontal cortex. As I hope you remember, there is still maturation going on here. As the prefrontal cortex is reaching its adult level of maturity. This h elps the prefrontal cortex direct more of the functioning of the limbic system, and this h elps us b ecome less and less prone to being overwhelmed by emotion when we n eed to make good d ecisions. But experience matters too. Of course our experiences and the lessons we learn from those experiences have an impact on our actual brain maturation. Think about college students. They’re constantly having n ew experiences, hearing different ideas, meeting new people, having to work together. You know a ll that group work that some of your high school teachers and professors do, the kind of work a lot of students scoff a t or may not enjoy, can actually b e a h elp for the maturation of the brain. We tend to become more cognitively flexible when we go about learning something with the assistance and the input of others. We’re b etter able to understand multiple p erspectives, and importantly, to b e able to understand those p erspectives without feeling threatened. That d oesn’t mean we s imply take other p eople’s opinions and move on. No, not at a ll. In fact, we are able to sort of balance and think a nd go back and forth b etween d ifferent modes of thinking, coming to our own p erspective but having b een influenced by the perspectives of others. One of the frustrating things about it, for some, is it can feel like you’re changing your mind a lot during this p eriod of life. So from 18-­‐25, all of this working together and multiple p erspectives and everything is terrific, but it also usually results in emerging adults having a P16 Podcast Transcript, Amy Himsel, Ph.D. C hapter 11, p. 4 lot of different ideas and changing their minds frequently. But really this is showing cognitive flexibility and a willingness to consider feedback from their friends and from professors as well as lessons learned or feedback coming from their own experiences. Even mistakes that they’ve made. And p erhaps the cognitive flexibility of emerging adults h elps our nation develop. Because it often is this segment of the population that leads a p ush in a n ew d irection. Being willing to question the traditional notions of past generations. I think right now we’re seeing this in the research on attitudes towards homosexuality for example. Emerging adults are far more likely to support gay marriage than adults of any other a ge. People often have d ifficulty thinking whenever they have some sort of anxiety going on at the back of their minds and the concept of stereotype threat shows us that a fear of confirming a stereotype can lead p eople to feel anxiety which diminishes their p erformance, let’s say on an achievement test. Let me give you an example. Researchers have found that if you make a certain stereotype more salient in a person’s mind b efore they take a test that their performance may b e a ltered. Especially if the stereotype is something n egative about a group to which they b elong. Okay, for example, there’s a s tereotype that women aren’t good at math. Well, research, which cleverly increases the salience of that s tereotype through instructions for example, maybe instructions that say, “This is a test that is meant to d istinguish gender differences in mathematical abilities.” When you give that instruction b eforehand, women’s scores tend to b e lower then when women are s imply told this is just a math test and nothing is said about gender differences. That’s stereotype threat. Stereotype threat can also b e connected to ethnicity. The s tereotype of African-­‐American students not b eing as smart as Caucasian students can b e brought to mind and increase the anxiety and lower the p erformance of African-­‐Americans taking a certain kind of achievement test. Alright, so that is stereotype threat. But, thankfully, in emerging adulthood, the vulnerability to stereotype threat can b e reduced. Whenever college s tudents internalize the b elief that the brain is plastic and the brain responds to experience, then they are less likely to b e affected b y stereotype threat. This is probably b ecause they are now more convinced than b efore that intelligence or math ability is changeable and not innate. Let me clarify s omething, b y the way. I find that a lot of students and people in general think that they are not affected by stereotypes. They might say, “You know what, I’ve always known that the brain is plastic and responds to experiences, so I d on’t think that would have an effect on me.” We would likely s ee that if they were put in the testing situation, though, that it would have an effect on them. Prepping someone to think about how the brain is plastic and responds to experience can have a great impact on their p erformance. And can influence the kind of stereotype threat that is going on in the back of their minds that might n ot even b e fully conscious to them. If fact, it’s probably not fully conscious. Even without instruction though, there are certain s ettings that can h elp reduce s tereotype threat as well. For example, women tend to do better in colleges that are all female colleges and African-­‐Americans tend to p erform b etter at colleges with predominantly African-­‐American students. Maybe that’s because salient reminders of the threat, of the stereotype threat, are not present, are not brought to mind as much. The experience of going to college, experiencing h igher education, has an impact on cognition as well. I see this happening a lot. There’s a d ifference b etween first year college students and many of the graduating s eniors. At a community college, we have a lot of first and s econd year s tudents. It’s common for first year s tudents to think there are facts and there are falsehoods and the professor will tell you what the facts are. And if you just memorize what the professor says, then you’ll know the facts. These first year students may get frustrated when they find out that the answers to their questions are a lot P16 Podcast Transcript, Amy Himsel, Ph.D. C hapter 11, p. 5 more complex than they expected, that knowledge itself is not b lack and white. Later in college, they begin to question everything. Opening up to multiple p erspectives that influence n ot only their school work, but a lso their social world and their identity as well. Near graduation, most college s tudents b egin to s ettle upon p ersonal commitments, b eliefs that they consider b est for themselves, but that they understand are not n ecessarily the b est for others. In the terms of Perry, who conducted research a t Harvard University, we b egin college with a dualistic type of approach to cognition, thinking that there’s right, and there is wrong; good and bad. We encounter a lot of n ew ideas. We meet n ew p eople, different p eople with d ifferent backgrounds. And maybe you’ve had this experience b efore, but has a class or experience in college ever kind of b lown your mind? Made you go “Wow, I hadn’t thought about that.” Made you re-­‐evaluate something in your own life that you always thought was one way and now might be a d ifferent way. Through those kind of experiences, a lot of college students move from dualistic thinking to relativistic thinking. That’s the opening up to the fact that there’s a ll kinds of possibilities. This can be a scary time or a frustrating time or an exciting time, d epending upon your p erspective and depending upon how threatened you might feel by those multiple possibilities. In fact, some college students retreat back into dualistic thinking, just convincing themselves that their original viewpoint was the right one. But a lot of college students push through relativistic thinking and end up coming to some of their own p ersonal commitments. That means understanding all of that relativity, understanding that there are different possible solutions -­‐ different, equally valuable opinions to come to. We are b ecoming ever more d iverse, which means that when we go to college, a lot of us are interacting within even more wide range of p eople, d ifferent ideas, d ifferent p erspectives. Those emerging adults coming into college with a very Western orientation a lready are more accustom to questioning, having opinions, d ebating with others. It goes a long with the Western cultural ideal. And it tends to b e part of the hidden curriculum of our colleges here, which can b e d ifficult for p eople of other cultural, or economic, or generational p erspectives to d eal with. A lot of it d epends upon a person’s comfort level with the idea of choice. Making choices, having a choice of what opinion to take, debating with others. Usually, when conflict occurs b etween cultures in this regard in the American college classroom, it might a t first b e very confusing to deal with the relativistic thinking. But most college students push through and learn q uite a bit from the experience. And even if the p erson doesn’t stay in college for four years, a little b it of time in college still correlates with increases in cognition and increases in success in life. Identity and Intimacy Identity is the task that Erikson originally said is s tarted and finished in adolescence. And intimacy was the stage of psychosocial d evelopment he b elieved came n ext. While it’s true that emerging adults are more likely to have a s tronger idea about their identity than adolescences d o, identity may not yet b e achieved in all areas or may not yet b e achieved in any area. There’s a lot of figuring out that still goes on well across the d ecade of the twenties. This is especially true when it comes to figuring out vocational identity. In other words, answering the question, “What do you want to b e?” Vocational identity is the push b ehind most emerging adults’ d ecision to go to college. And this is probably a good idea for most of us b ecause a college education is correlated with income. But note that it’s a correlation, not a cause and effect relationship. S o that means your odds of having a good paying job get higher, your odds increase when you have a college education. But it’s not a guarantee. Many of us have work experiences during our emerging adulthood as well. Often times b ecause it’s absolutely necessary to b e able to support ourselves or b ecause we’re looking for experiences that can h elp us P16 Podcast Transcript, Amy Himsel, Ph.D. C hapter 11, p. 6 figure out what we want to do with the rest of our lives. Job experiences during emerging adulthood tend to be short-­‐term, and a lot of switching goes on. These jobs are often not directly related to vocational identity. And jobs at this age feels very temporary. Most of them really are temporary. Most of them won’t last long. That’s not because of job lost necessarily, b ut b ecause emerging adults change their minds and make different decisions. On one extreme, an emerging adults can get f eedback from parents, like, “When are you going to get a real job? Stop messing around.” But there are also risks of going too far in the other direction, having such a firm notion of vocational identity that you’re looking for the perfect job and the p erfect fit. Here’s the dirty truth, there is n o p erfect job. There is no perfect career. Emerging adults who think this way are s etting themselves up for some disappointments. And how d o they d eal with these disappointments? That can b e a big challenge of emerging adulthood. What makes it more complicated is for those emerging adults who’ve gone through a lot of education and preparation for this p erfect career may feel like they should b e able to get jobs a t a higher level coming right out of s chool than they’re really q ualified for. It’s tough because it’s often hard to know in the moment of making these decisions whether your d ecisions are b eing guided b y an unrealistic ideal or whether all of the job changes and the s witches that you’re going through are ways of a voiding making a decision. How will you know for sure? It’s a challenge that people have to sort of feel out on their own. Another main source of continuing identity struggle in emerging adulthood relates to ethnic identity. This is really important for us to understand as a nation because we are increasingly d iverse. In fact, fully half of today’s emerging adults have a d istinct ethnic h eritage. And what I mean b y that is that they are either recent immigrants or have non-­‐European ancestors. An ethnic identity b ecomes more fine-­‐ grained in emerging adulthood. An Asian-­‐American girl who is happy to b e called Asian-­‐American as an adolescence might feel it’s very important to clarify as an emerging adult that she is really Korean-­‐ American, that Asian-­‐American is too broad. Emerging adults are a lso most likely to feel a cceptance or even pride related to their ethnic h eritage while a t the same time hanging out with friends from different ethnicities and from d ifferent backgrounds. Hanging out with p eople of d ifferent backgrounds can trigger curiosity that h elp with ethnic identity. Even Caucasians, otherwise known as ‘white p eople,’ tend to become more curious about their ethnic h eritage during emerging adulthood. Of course, everybody has an ethnic h eritage. The Caucasians in the United States who are d escendents from people who immigrated here long a go may not b e left with much of a s ense of their, often very mix, ethnic heritage, b ut may b ecome very curious about it as they interact with friends who have a lot different experiences and backgrounds. Ethnic identity may present a b ig challenge to immigrant emerging adults b ecause they so recently made the s witch from their native country to the United States and this can include a lot of conflict with parents with what is and is not appropriate. Most notably, in the United States, our cultural n orm is that children make their choices independently, especially when it comes to career choices. Joe chooses a career that’s a good fit for Joe, n ot n ecessarily a good fit for Joe’s parents, right? Well, immigrant emerging adults may feel a d esire to make their own d ecisions while also feeling guilty about going against the wishes of their parents. As a result, conflict can increase in the parent relationship with their emerging adult child. Regardless, the s earch for ethnic identity has countless possible outcomes. Every emerging adult make decisions and choices about which aspects of their h eritage to embrace and which to reject. And some of the parts they choose to reject now, they may find later re-­‐emerge as important and as things they want to embrace later. For example, it’s pretty common for p eople ages 18-­‐25 to think that the religious P16 Podcast Transcript, Amy Himsel, Ph.D. C hapter 11, p. 7 aspects of their h eritage aren’t so important. But some of those individuals may find later on when they get married or when they have children that those issues b ecome a lot more important to their ethnic identity than. The point is even if we settle upon certain ethnic identity during emerging adulthood, it’s still likely to change a little b it at least across the lifespan. The process of figuring out this tough task of ethnic identity is h elped b y college classes that make u s think a nd learn about cultures and including sometimes our own cultural h eritage. Erickson originally believed that intimacy d evelops after identity d evelopment is complete. That’s n ot necessarily the case these days. Intimacy involves sharing ourselves with others. And those others can be friends, family and romantic partners. Of course we have relationships with all of these individuals even as we are still figuring out identity. And it appears as though in recent generations, the development of intimacy and identity are happening more at about the same time d uring emerging adulthood. It can b e really difficult to manage the stresses and the challenges of intimate relationships, especially during a time when most emerging adults are postponing those transitions into adult roles, like marriage and parenthood. Emerging adults make the most of this time though b y maintaining a wider circle of friends than they’ll have later as married young adults. Friendships have b ecome more d iverse too with more cross-­‐sex friendships that involve no romance. Think about it. Emerging a dults have a lot of contact with the opposite s ex, and with others who have d ifferent backgrounds, through college, through work experiences, and other common emerging adult experiences. And facebook, and texting. As much as they may b e put down or misunderstood b y older generations, seem to strengthen the ties b etween emerging adults, especially among those who originally met face to face. And the gender differences that used to b e s o common in friendships are no longer quite as distinct. For example, male friends these days tend to d isclose more to each other today than they did in past generations. Now what about romantic relationships? Wow, what a huge topic during emerging adulthood. Choosing a life partner. That’s what most of us are hoping to do. We get b etter at choosing life partners as we get a little bit older. That’s what the s tatistics tell us b ecause the risk of divorce d ecreases the older we are when we get married. In other words, p eople who get married a t the age of 19 have a higher risk of divorce than p eople who get married a t the age of 30. The best b et for figuring out whether someone is going to b e a great life partner is to start with friendship first, and then s ex later. Going in the opposite direction of sex first and then getting to know each other b etter is not likely to lead to long-­‐term relationship success. Some couples think it’s good to test drive the relationship and live with each other before they get married. This is called cohabitation, and more and more young couples are trying it out. Contrary to common b elief, though, cohabitation doesn’t reduce the risk of d ivorce. In fact, cohabitation correlates with a higher risk of d ivorce. It’s unclear a t this point, though, whether this has more to do with the act of cohabiting or has more to do with the q ualities of the p eople who make the d ecision, the choice to cohabit. I’ll just give you a couple examples. Couples who d ecide to live together tend to be couples who are already quite d ifferent from one another, more of the opposites attract than the birds of a feather flocking together. In addition, couples who cohabit tend to b e less conventional than the a verage individual and tend to b e less religious. These aren’t n ecessarily good or bad things, it’s just that those are a lso correlates of divorce as well. When couples have a lot of d ifferences b etween themselves, when couples h old unconventional views, when couples are less religious, their chances of d ivorcing later are a lso h igher. So you s ee what I mean. We don’t know if it’s a s election factor, that those are the type of individuals most likely to choose to live P16 Podcast Transcript, Amy Himsel, Ph.D. C hapter 11, p. 8 together or if there’s something about the act of cohabiting itself. Maybe the experience of not having to make a commitment fully that may have the impact. Maybe future research will tell us. In the United S tates, we’re very focus on whether we really love the p erson, you know, and this is the biggest issue that drives most people’s d ecision about choosing life partners. Everybody understands the feelings of attraction, the spark, the physical interest in another p erson, right? And that’s certainly part of love, especially the early part of love. But intimacy a nd commitment are important as well. Intimacy involves really understanding and knowing each other, the good and the bad. And commitment is the decision to really try and make things work. The research tells us that the first thing that s tarts to decrease of those three components is passion. Couples aren’t able to keep passion a live on a consistent level all throughout their many d ecades together as a couple. But commitment a nd intimacy due tend to grow with time. And d ivorce and less and less likely the longer a couple is together. Maybe b ecause the commitment and intimacy has grown. Family relationships continue to b e important for emerging adults. And even more so for today’s emerging adults than in the past because today’s 18-­‐25 year olds are not exactly independent. Today’s transition into the full adult status, whatever that means, it might include financial independence and vocational goals that are met, takes longer. Because of this, parents have remained important sources of support and important influences on their adult children during this time. Besides, today’s families have fewer children which means that today’s midlife parents of emerging adults have more a ttention a nd more concern and more energy to d evote to their one or two kids. And parents are n ervous b ecause past to successful adulthood are not as clear as they used to b e. They’re different than from when parents were your age, so parents may feel very s trongly that their emerging adult kids n eed continued support. Emerging adults might move back in and live with their parents. Even if they don’t, many are getting significant financial h elp from their parents, like h elp paying their rent or insurance. It’s not that difficult for financially s ecure parents to help their emerging adult children transition to hopefully and more s ecure future but it’s obviously a much b igger challenge for parents who are less well-­‐off financially. In fact, the less money parents earn, the lower the chances their emerging adult children will attend college. In such cases, the emerging adults have to financially support themselves a nd work is going to take priority over school. Some may choose to complete their education gradually, part-­‐time, whereas others who may have really wanted to get a college education may d ecide that they can’t manage the responsibilities of their work while also being a student. The bottom line is that parental support during emerging adulthood can go a long way. It d oesn’t have to b e financial, but the financial support that, let’s say help an emerging a dult may get from college graduation through a long job s earch until h er first real job has s et h er on a course that’s more likely to lead to future success. But support can b e emotional. And support can b e very instrumental as well. For example, with an emerging adult who has a child and whose parents are h elping babysit the child or taking care of the child while the emerging adult is getting some of h er coursework done to move towards career goals. So do you see what I mean about a lot of flux? A lot of change? A lot of excitement but also a lot of uncertainty? I know many of you who are listening are going through emerging adulthood right now and I’m sure you can relate very directly to a lot of material in this chapter. Maybe it will make a slight contribution to h elp you figure out who you are, what you n eed, who you want to b e with, and what you want to do with your life. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 12, p. 1 EPISODE 12.1: ADULTHOOD - PHYSICAL HEALTH AND AGING In this episode, weʼre going to talk about adulthood, specifically the development of the physical body and the mind from about 26 until about 65. Physical Health and Aging In the United States, we really don't like to accept the fact that we all will go through a physical aging process. I think secretly many of us are hoping that scientists will figure out how to prevent aging entirely by the time we get to be older adults. That's not going to happen. The gradual aging process happens to us all and is referred to as senescence. We reach our physical health peak in late adolescence and early adulthood, but the decline in our physical health begins in early adulthood. It's just that it's very gradual and we often won't notice until middle adulthood. And that depends also on our lifestyle and how well weʼve been taking care of ourselves. But senescence will occur, and it will occur to our insides (our organs) and also to our outsides (our physical appearance). With physical appearance, for example, we have connective tissues of the body like collagen that help give skin its strength and elasticity, right? But collagen decreases at a rate of about 1% per year starting in early adulthood. You're probably not going to notice this change from age 26 to age 27, but comparing yourself at age 26 to looking at yourself at age 40, for example, it becomes more obvious how the skin is aging. And it's one of the areas of physical appearance that people begin to notice the most in midlife. Our internal organs are aging as well, and in particular our sense organs show signs of aging. We often notice senescence first in our sense organs compared to our other organs, so that means that we might notice our hearing declines and our vision declines. Regarding vision, in our 20s onward we become more and more likely to be nearsighted, meaning we can see things close up but have difficulty seeing things that are far away. But then, as we reach middle adulthood, the incidence of farsightedness increases, and that's when we have trouble seeing things that are close up. The thing is that as older adults, many of us will have both: nearsightedness and farsightedness. With hearing, when we have lost a significant amount of hearing, it's referred to as prebycusis. That just means aging hearing, and it's one more common as we get older. Once we reach age 65, more than half of us will have presbycusis. Senescence certainly is affected by genetics. Our bodies are not meant to last forever, and genes play a role in the aging process. But, our behaviors and our environment also contribute to the aging process as well. Certain poor habits have a particularly strong influence on the rate of senescence. Take smoking. Thankfully, smoking has been decreasing in the United States, but itʼs still the #1 preventable cause of death here in the United States. Adolescence is a vulnerable time, because people who start smoking in their teenage years are the most likely to become addicted and to experience several decades as a smoker. Drinking can also have a negative impact on aging, but moderate drinking can actually improve health. It's interesting because there's a correlation between moderate drinking, and that means one or two drinks a day (depending on your gender, and depending on your height and weight). Those people actually tend to live longer than people who never drink at all. Why is this the case? One of the explanations scientists have hit upon is that alcohol seems to have a positive effect on cardiovascular functioning. Remember, moderate intake of alcohol has a positive effect on cardiovascular functioning, but abuse of alcohol (like, heavy drinking, regularly having P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 12, p. 2 three or four or five drinks in a row several days a week), this can have absolutely disastrous effects on senescence and our health in general. Abuse of alcohol is correlated with cancer of many kinds and is also correlated with liver damage. Senescence is affected by what we choose to put into our bodies. As we age, our metabolism decreases gradually. So, to maintain our youthful figure, we have to actually consume fewer calories and burn more calories. Most of us don't do this, and gradual weight gain is common. We also have a growing problem of obesity here in the United States. Obesity is defined as having a body mass index of 30 or more, and it's correlated with lots of health problems and accelerated aging. In fact, the increase in obesity in recent years is expected to result in a pretty dramatic increase in diabetes later on. Why is this happening, and why is it happening here in the United States? The research tells us that we are eating fewer nutritious and healthy foods. I mean, even compared to data collected five years ago, we are eating fewer nutritious foods, fewer healthy foods. Instead, we are eating more high-fat and low-nutrient foods. Much of this has to do with our consumption of fast food and other processed foods. Plus, were not as physically active as we need to be. And by “we”, again, I'm talking about residents of the United States. Inactivity is a problem that contributes to obesity, and it's also a lifestyle factor that, even if a person isn't obese, can have a negative impact on senescence. Staying physically active is correlated with all kinds of good stuff, all kinds of positive health outcomes. There's no doubt about it: exercise helps us live longer, healthier lives. But, environmental factors influence whether or not we stay physically active. For example, those of us who have active friends are more likely to be physically active across the lifespan ourselves. In addition, living in a neighborhood where there are places and areas that are safe and open where we can exercise is associated with greater physical activity. This would be places like bike paths and parks and pools – places where it easy for us and safe for us to maintain our activity. Still, even though we know a lot of this (maybe this information wasn't new to you at all), getting ourselves to exercise regularly is often a constant struggle. We work a lot. We drive a lot. And we watch a lot of television or sit at our computers a lot. And because our time is consumed in this way, there is less time during the day to spend on being active. In the past, when work was more physical to begin with – for example, when more of us were farmers or working the land in some way or another – we were getting exercise just as part of our regular daily activities. But most of us don't have work that involves physical activity, and most of us don't walk to work. Most of us don't even take the stairs once we get to work. Just 30 min. of exercise a day could prevent an estimated 250,000 deaths a year in reduced risk of heart disease alone. Beyond heart health, regular exercise enhances the immune system, decreases stress, and helps reduce depression and anxiety. I've just described a number of findings related to activity and eating habits and other environmental factors related to our health, but how do we measure health? There are a number of different ways that scientists assess health. The most blunt way is to assess the death rate. This is a measure of mortality, and we see from measures of mortality that women tend to live longer than men. In fact, it's about a five year gap in the United States. Men tend to die, on average, five years earlier than the average woman. It isn't clear whether this difference is biological–maybe something to do with the fact that women have two X chromosomes instead of one, or because of some protective benefit P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 12, p. 3 of estrogen–or whether this difference has environmental or cultural components to it. Women tend to maintain stronger friendships, and they tend to notice and act on any kind of health problem that they spot. They're more likely to go to the doctor at the first sign of some kind of problem, whereas men are often reluctant to go to the doctor until their situation gets pretty bad or until a woman in their life basically badgers them enough until they actually do go to the doctor. So that's mortality: looking at death rates. We can also measure the rate of diseases, and thatʼs a measure of morbidity. With morbidity, weʼre looking at all kinds of diseases that exist in a population and how many people have those diseases: diseases that could be acute or chronic, diseases that are life-threatening or are not life-threatening, any kind of disease is measured through a morbidity measure. Again, there's a gender difference here, but in the opposite direction as it was with mortality, with women showing higher rates of morbidity for all diseases except for cardiovascular disease during the middle adult years (which would be between about 40 and about 65). Disability is another way to measure health, and this reflects an impairment in the ability to function in daily life. This could be an impairment in physical functioning, emotional functioning, or mental functioning. It's a limitation that presents a challenge in an everyday way. A person may have to use a wheelchair, for example, or may have a condition that makes it difficult for them to walk very far. Similar to morbidity, women often have higher rates of disability than men. And, for the most cheerful measure of health, next comes vitality. Vitality is a measure of a zest for living, a love of life, or an energy for life. And it's related more to personality than to physical factors. It's not necessarily correlated with physical illness or physical health. A person could have a very serious physical illness, which would mean that they have morbidity and perhaps even disability, but a high rate of vitality showing that they still have a love of life and energy for doing the things that they enjoy in the midst of dealing with what might be difficult circumstances. Whether a person is physically healthy or physically ill may not relate at all to vitality, and vitality tends to be related more to personality. Socioeconomic status correlates with these measures of health. In particular, it correlates with mortality, morbidity, and disability. Across the world, the people who have more years of formal schooling and people who have achieved some measure of financial security show lower rates of mortality, lower rates of morbidity, and lower rates of disability. The Sexual-Reproductive System We see senescence in the sexual reproductive system. In regards to sexual responsiveness, it takes adults a longer amount of time before they feel aroused, and it takes longer for them to achieve an orgasm. But most couples handle these declines pretty well and aren't too bothered, especially if they have a strong emotional relationship. These changes in sexual responsiveness are gradual and may not be noticeable until further into the midlife years in the 40s and 50s. At a certain point when a couple has decided they no longer wish to have more children (and they may not have had any before), the fact that women lose their reproductive capabilities and eventually stop ovulating can actually be enhance sexual behavior for some couples because they no longer have to worry about birth control. Fertility declines across adulthood. This means that people are less and less likely to be able to reproduce, especially after age 35 and into the 40s, and especially for women. As P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 12, p. 4 she ages, a woman has fewer and fewer viable healthy eggs left. The eggs that are left as she ages may not be healthy eggs; they may have chromosomal abnormalities, for example. And eventually ovulation stops entirely. A man's sperm count decreases gradually with age, although there isn't an age where it just stops entirely. So the aging of the sexual reproductive system it is especially difficult for adults who wanted children but weren't ever able to conceive, or who had some children and wanted more but were able to conceive. This is called infertility, and it affects about 15% of couples in the childbearing years today. Today though, we do have more and more options for infertile couples. We have assisted reproductive technology, which allows many infertile couples to become parents through procedures like in vitro fertilization (IVF). During IVF a woman produces a lot of ova, and this is with the help of drugs that stimulate the ovaries. Those ova are removed from the woman's body and then combined it in the laboratory with the man's sperm. Hopefully, one or more or several of these eggs become fertilized, and then one or two of these zygotes are transferred into the mother's uterus in the hopes that implementation will take place... and it might not. The success rates of IVF vary by age, but in general about one third of IVF cycles are successful. Today, despite the widely publicized Octomom, most doctors are reluctant to transfer more than two zygotes into the mother's body at the time. This is obviously a good idea because, if both take and become implanted, then we have pregnancy with twins which increases the risks of a lot of complications but it is a kind of pregnancy that many women are able to maintain. If three or four or five or six zygotes are transferred into the woman's uterus and all of them happen to implant, or several of them happen to implant, now the health risks to the mother and to those developing humans increase greatly. At a certain point, especially for women, there's an end to reproductive capabilities. The aging of the sexual and reproductive system result in menopause for women, which isn't technically diagnosed until a year after a woman's last menstrual period. Menopause is when a woman is no longer ovulating, so obviously she's no longer able to become pregnant and it's the end of her fertility. Often times, menopause occurs around the age of 50 and it's the end result of several years of gradually decreasing amounts of estrogen in the bloodstream. As estrogen decreases, there are some common physical effects, like (obviously) decreased fertility, but also changes in body temperature (like hot flashes). There are psychological effects too that are reported but they vary widely, even from woman to woman in the United States, and they vary widely by culture as well. In cultures where aging is respected to a higher degree than it is here in the United States, women tend to have an easier time with menopause from a psychological perspective. It relates to attitudes about aging, because menopause is a clear signal that the body is aging. How we handle that is going to be influenced not only by our own emotions and our own personalities, but very much by the culture that we live in and the extent to which aging is valued. It was once common for doctors to recommend hormone replacement therapy during menopause to counteract some of the symptoms of menopause and to improve bone health and cardiovascular health as well for women, but now scientists think that in that earlier research, the correlation might have more to do with income and education than with hormone replacement therapy. In fact, for the kind of hormone replacement therapy that is estrogen only, long-term use has been found to correlate with an increased risk of heart disease and other illnesses. So, these findings leave many women uncertain about what to do. Men also experience a gradual decline in their sexual reproductive functioning. This P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 12, p. 5 relates mostly to the decline in testosterone production. There is disagreement among scientists whether this is a significant enough change to warrant men getting their own title–like a counterpart to menopause. Some would suggest that it be called andropause. Testosterone, by the way, is an androgen so that's where the name would come from. But keep in mind that men do not reach an end to their reproductive capacity, at least not like women do. Besides, psychological factors like anxiety and anger that men experience can actually lead to lower levels of testosterone, too. Taking care of their physical health and psychological health is often very helpful for men's sexual health across adulthood. Some research suggests that taking care of their physical and psychological health is even more important for sexual health for men than taking a prescription for Levitra or Viagra. EPISODE 12.2: ADULTHOOD – COGNITION, INTELLIGENCE, AND EXPERTISE In this episode, the second one on the body and mind in adulthood, we will focus on aging and intelligence as well as other specific cognitive strengths of the adult years. Aging and Intelligence The brain is an organ, and the brain ages like all of our other organs age. The brain slows down gradually over time as the brain ages. It also gets a little bit smaller. This is because over time we have fewer neurons, fewer synapses. The communication between neurons as well slows down a bit. These are gradual changes that most of us won't begin to notice until we get well into middle adulthood or even later. But the outcome of these gradual changes is that it's harder for adults to stay focused, especially when they're doing something really complex like solving a complex problem. They are more distractible. Their attention can be taken away more easily, and that can be because of external noises, or even by thoughts or intruding memories or other kinds of emotional problems. Weʼre not as good at multitasking as we age across adulthood, compared to our younger years. In adulthood, the brain needs to be taken care of. We need adequate sleep. The brain becomes more sensitive to important neurotransmitters when it's fully rested. This is because while we're asleep the brain goes through a consolidation and repair process, churning through the events that have occurred that day and repairing any little wear and tear and damage that may have happened across the day. In fact, when we get enough sleep, and especially when we get adequate REM sleep (rapid eye movement sleep), our memory is improved. The challenge is that sleeping itself becomes more erratic as we age, more problematic. The problems that we have with sleep may be the result of aging, but sometimes theyʼre an indication that something else is wrong. For example, one of the common symptoms of depression is changes in sleep and trouble sleeping. A small portion of adults will notice changes in their brain before late adulthood. This may be an indication of early Alzheimer's disease. Early Alzheimer's disease is often caused by a dominant gene, and it tends have really strong presence in the family. What I mean is that you see it running through the family with other members succumbing to Alzheimer's at an early age as well, maybe beginning even in their 40s. This is very rare from age 25 to age 65, by the way. If a person has abused drugs repeatedly over the years, maybe they've been drinking P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 12, p. 6 heavily for years or they've been abusing nicotine for years, this can also impact brain functioning, as can hypertension. Having high blood pressure is an indication of problems with circulation, and that makes a difference in terms of brain functioning as well. Even though age-related decline is inevitable we can do a lot to keep our brains as active and sharp and as young as possible. We can't prevent brain aging from occurring entirely, but, by staying physically active and keeping our brains cognitively active, we can slow down the aging of the brain. But what does that mean for intelligence? How smart will we be across the adulthood years? This is a question that researchers have been investigating for several decades. For a long time the assumption was that there's one kind of intelligence, a general intelligence, that measures a multipurpose intelligence that's there underneath our performance in a number of different areas. Think about school, for example. Students who tend to do a good job in math class also tend to do a good job in English class. So the fact that their talents in one area are correlated with abilities in others was thought to be an indication of an underlying general intelligence. With this in mind, we can take a look at changes in intelligence across the lifespan by measuring IQ. By the way, we are going to talk a little bit later about whether it's appropriate to think of intelligence as just one thing, as a general intelligence, but for now letʼs review the research on IQ as a measure of intelligence. What happens to our intelligence as we age? It depends upon how we test this question. The results that we get vary based upon the different methods. For example, if we take a look at groups of people of different ages, we find that younger people tend to have higher intelligence scores than older people. This would be a cross-sectional research design, and the early studies of intelligence across the lifespan were cross sectional. They showed that people in their 20s and people in their 30s have higher scores on IQ tests the people in their 70s or 80s. At first, an interpretation was made that intelligence declines as we age, which is pretty depressing. But it's also inaccurate, especially once we started to understand the impact of context and history and other generational factors on our ability to maximize our intellectual potential. The environment has changed in a major way. We are all going to school for a lot longer than many of our ancestors did, and many people in older generations did. The kinds of things weʼre learning about are very complex from a cognitive perspective. This doesn't mean that we are genetically smarter than those of older generations, but it does indicate that the environmental changes that have gone on since that time have impacted our development of our intellectual potential. We see generational differences in IQ scores. Remember the Flynn effect? That's the finding that intelligence scores keep increasing gradually over the years. This is a steady change that we see over and over again, and it's probably because a dramatic changes in our environment. So, when you measure people of different generations, what happens is there's the confounding factor of cohort differences that gets in the way. Longitudinal research moves us one step forward in terms of considering that kind of bias. Longitudinal research is when you take one group and you follow that group across several years. This is better than cross-sectional research but it still has problems. For example, if people are participating in a study for 50 years or so, they may start to get P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 12, p. 7 accustomed to the test and get better at it because they've been able to practice it a lot. In addition to that, sometimes people in longitudinal studies end up dropping out and the people that end up staying in the study tend to be the ones that were smarter in the first place. The smarter and healthier and better functioning people are the ones most likely to keep agreeing to participate in a longitudinal study, and all of this can have an impact on the findings. Perhaps you remember cross sequential research? This is a technique where we begin a longitudinal study, and when we get ready to assess that group again in the future (let's say five years from now), we add another cohort–another group of people–and we keep adding and adding until eventually we have several different longitudinal studies of people who are members of different cohorts. That way we can see whether we find that there are individual changes in intelligence and we can also at the same time compare the findings from one generation to another. This is what a researcher named Schaie did starting as his doctoral dissertation, and we now refer to the study as the Seattle Longitudinal Study. It's looking at intelligence and looking at many different components of what would usually make up an IQ test. What the Seattle Longitudinal Study shows is that the bottom line is that we get smarter on most elements of our mental abilities across adulthood, and our overall intelligence remains stable usually until later adulthood. The evidence suggests that most of our mental abilities peak somewhere in between age 40 and 60, and that if there are declines before the age of 60 it's often the result of some other kind of illness or disability. In other words, it's not a normative development. Specific Cognitive Strengths Now, let's talk about the other kind of abilities that may also be a part of intelligence above and beyond IQ tests. Intelligence is more than just IQ. That's something that almost all scientists agree on right now, but there is still disagreement on exactly how many other kinds of abilities are included in the concept of intelligence. One possibility is the two clusters approach: fluid intelligence and crystallized intelligence. This is an idea that intelligence is made up basically of two components–fluid intelligence, which deals with processing speed and how quickly we can solve new problems–and crystallized intelligence, which reflects the facts and the vocabulary and the knowledge that we've learned through our experiences and through our studying. Fluid intelligence, data processing speed, has to do with the capacity of our working memory–how quickly we can think and how flexibly we can think–and how skilled we are at solving new abstract problems. This kind of intelligence decreases gradually even starting in the 20s. However, it's not noticeable for most of us until we get quite a bit older, maybe into our 40s or 50s. It becomes most noticeable in late adulthood: age 65 or later. Crystallized intelligence goes in the opposite direction. Crystallized intelligence is facts and knowledge and vocabulary and the things that we've learned through experience. Think about a lifetime of experience. As we age we gain more and more experience, we have more and more opportunity to encounter new information and learn things, and accordingly crystallized intelligence tends to increase across adulthood. With the decrease in fluid and the increase in crystallized, we see on IQ tests that kind of balances out and we see IQ holding steady throughout the adulthood years. Another approach considers three clusters. This is Sternberg's triarchic theory of intelligence: analytic intelligence, creative intelligence, and practical intelligence. Let's P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 12, p. 8 focus specifically on practical intelligence. Practical intelligence is similar to common sense or street smarts or everyday problem-solving ability. In adulthood, practical intelligence is very useful because we encounter all kinds of real-life problems that we have to solve, problems where there are great stakes involved, problems that are important to us and that we very much want to figure out. This would include things like all of the tasks and challenges that come with managing the multiple responsibilities of adulthood, like relationships with people at work, relationships with people at home (including spouses, children, in-laws, grandparents), making decisions that impact others and yourself. Of the three kinds of intelligence, although creative intelligence and analytic intelligence are wonderful to have, practical intelligence is arguably the most valuable in our lives during these years. But wait–there's more! Maybe it's nine clusters. This would be Howard Gardner's theory of multiple intelligences. Gardner believed that there were a number of different kinds of intelligence, as reflected in the expertise of people who we consider to be very talented in a number of different domains, not just in school or in book smarts. Different cultures value different intelligences. This has an influence–a strong influence–on what we decide to teach our children and how we as people judge others as smart or not so smart. But what if your particular form of intelligence isn't valued in the culture in which you live, or isn't valued during the era in which you came of age? This can present a problem. For example, if a person has grown up in a nation where schooling is emphasized the most and more mathematical and verbal abilities are emphasized above all others, he or she may have repeated experiences of not doing well. Maybe this child's intelligence is more musical or spatial or, perhaps, bodily kinesthetic. It may be difficult for that person to overcome feelings of inferiority and a feeling of learned helplessness about the repeated mistakes and failures they've experienced. As we look in on other cultures, we may make a mistake in assuming they have less intelligence than we do, when in reality it may just be that other skills are valued more strongly within that particular culture and are emphasized and taught to the children. So the nine clusters idea of intelligence helps us understand cultural differences and helps us understand the unique challenges the children–and then later adolescents and adults–face if they don't fit in with the kind of intelligence that's most valued in their own culture. The good thing is that learning occurs across the lifespan and different intelligences can be revived and improved upon beyond childhood and adolescence. But, as you know, as we have discussed, the adult years do involve losses: losses in our abilities, losses in our physical functioning…and the previous assumption was that infancy and childhood and adolescence were all about gaining: gaining skills, abilities, gaining knowledge…and that adulthood is just a prolonged period of loss. This is no longer understood to be the case. Across the lifespan, we experience gains and losses. Yes, the proportion of loss is greater as we age than it was when we were younger. That's true. But what matters more than the fact that we've had losses is how we adapt to those losses. Selective optimization with compensation is a strategy that adults use more and more as they face and learn how to accommodate the losses they experience as adults. Selective optimization: that means that we identify and maximize the remaining skills that we have. What about compensation? That just means that as we are identifying and maximizing our remaining abilities, we are at the same time trying to compensate for our losses. Adults often grow really good at using selective optimization with compensation and may show similar levels of functioning or achievement or on-the- P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 12, p. 9 job performance as younger people do. But if you take a look you'll find a lot of the reason why this is the case is because they become very skilled at making the most of the things they're really good at and making up for the things that are starting to decline. In fact, as each of us ages, and we don't have to be 85 years old to experience this, we all become experts. We are experts at something. Of the gazillion things we have the choice of focusing on or paying attention to, we end up focusing on a relatively small set of interests and skills that happened to be particularly appealing to us as individuals. This includes the information we were interested in memorizing or learning, but also includes the knowledge gained from experiences that we've had over time through consistent practice. So, it's appropriate to think of ourselves as selective experts. When is expertise in a particular area actually reached, though? It's hard to say exactly. It doesn't line up perfectly with age, but has more to do with the kind of decision-making that's typical of an individual in a particular area of functioning. When our thinking and our decision-making become more intuitive, automatic, strategic, and flexible, that indicates that we've developed an expertise. Expert thinking is intuitive. When something is intuitive it feels like you just know something, but you may not be able to explain clearly what exactly it is or why you're doing something in a certain way. It's that your knowledge has accumulated to such a point that you're making some decisions without full conscious awareness of all of the steps you're going through your mind. Things may be too subtle to explain in words. I see this when it comes to taking notes and studying. I've developed a lot of intuitive habits that can make it a challenge to explain to others–to novices, to students who are new at taking notes–the techniques that I'm following. I don't really have to think much about how I'm taking notes. I just kind of have learned over the years how to do that. Expert thinking is automatic. That means it's well practiced and efficient. Again, it may be partially unconscious in this case because it's happening so quickly, the ideas are coming to the expert so quickly. The thoughts are so efficient that it's difficult to stop the brain and go, “Wait a second. What am I doing here?” Expert thinking is strategic. Experts can develop a plan of attack. They realize there's some sort of problem that needs to get solved and, in the moment–spontaneously– experts come up with better strategies and have access to more kinds of strategies than nonexperts have. In the moment of making those decisions, those strategic decisions, experts are better able to regulate their emotions, and that allows them to be more successful problem solvers. For example, strategies can help older typists maintain their speed and accuracy of their typing, competing with those of younger typists, by using strategies that help them compensate for the loss in fluid intelligence, the slower reaction time that they have. Older typists uses strategy oftentimes of reading further ahead in the text that they're typing so that they don't have to look back and forth as much. That looking back and forth with typing takes up more fluid intelligence, so by having that strategy of reading further ahead they actually are able to maintain a similar level of functioning by selectively optimizing and compensating. And finally, experts thinking is flexible. Experts are willing to experiment and try new things. They're willing to go out on a limb. They may even be a little bit excited when a new challenge pops up that allows them to try out some unique and innovative P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 12, p. 10 strategies, because this could lead to interesting insights. With all of these characteristics of expert thinking–that it's intuitive, automatic, strategic, and flexible–it's interesting to notice the contrast with novice thinking. Novices are newcomers to a certain area. They are non-experts. Novice thinking tends to be more cumbersome, it tends to rely more on memorizing–memorizing rules or regulations or information. It takes longer for a novice to come to a decision. Their use of strategies is not as well developed because, first of all, they havenʼt learned as many strategies as experts have, and they're not as good in the moment at spontaneously reacting and changing when they need to change strategy. Novices are not able to be flexible. In fact, their thinking is more rigid: they've learned certain ideas and certain rules and they would prefer to just be able to keep applying them. It's difficult for them to make good decisions in the flexible way that experts do. So, as we all move along our path in life, becoming experts at whatever it is we are choosing to do, does that mean that we just get better and better when we get older? Is it a function of age? Well, yes–age involves experience and gives us a lot of opportunities to test out strategies and get better and better, right? But interestingly, the experience of cognitively complex work–like, occupational challenge–is correlated with intelligence in adulthood. The experience of becoming more of an expert, especially in careers or with hobbies that require lots of thinking, that kind of effort on the part of our brains tends to help enhance our cognitive functioning. So, as you struggle in college to learn all of this material and get into a job where you're probably also going to still be struggling and learning and always encountering new information, just remind yourself that you're giving your brain a good workout. P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 13 p. 1 EPISODE 13.0: ADULTHOOD – PSYCHOSOCIAL DEVELOPMENT From age 25 to age 65, so much happens. We make a lot of decisions, like where to work, and who to marry, and how many kids to have. We have numerous responsibilities with all of these areas of our life and the way that they overlap. And we're faced with many opportunities to demonstrate our coping skills. In this episode, we examine some of the main issues that arise in psychosocial development during adulthood. Ages and Stages We can take a stage based look at psychosocial development, which is focused on how different experiences that tend to occur at certain ages in the lifespan have an impact on us. But we can also consider how adult development involves a continuity of, for example, personality–that we see similarities in the way that we behave across the lifespan. Let's talk about stages first. Erikson was the psychologist who was interested in looking at development past the adolescent years. He was the first one to create a life span theory. In adulthood he believed that we face the crises of intimacy versus isolation and generativity versus stagnation. Erikson thought of intimacy as the primary challenge of young adulthood: the focus is on being really close to others, finding satisfying close and intimate relationships. This includes not only romantic relationships but also friendships and family relationships as well. As we grow a little bit older, we become more and more interested in the way in which we are contributing to society in some manner of fashion, whether it's through the way we raise our children, or through the work that we do, or the volunteering that we do, or any combination of the above. I will tell you more about each of these big issues a little bit later when we talk about relationships and we talk about work and parenting. But we do know now that the experience and the desire for intimacy and generativity aren't closely linked to age as Erikson originally believed. Besides, the timing of things in life? That tends to change with history, right? That's the point of the concept of the social clock. The social clock is a culturally determined schedule, like a timetable, of the general age ranges when we expect certain life events to happen. It's the idea that, "People should get married before they're 40. People should have their kids before they're 45. If you don't have a career set yet by the time you're 30, something's wrong." I'm not saying that any of the statements are true, but what I'm demonstrating is that these are attitudes held in general. They're norms that influence people's ideas and opinions and sometimes behaviors. The social clock changes in response to cultural changes, but also in response to historical time. Right now in the United States, the social clock is more flexible than has ever been before. In the past, the idea that you would have children in your 40s was much less a prominent notion. In the past it was assumed that people would want to retire by the time they're 60. Well, we are living longer and many of us want to keep working because work is interesting, satisfying, or because we really need the money. These kinds of changes have left us with a social clock that offers us more flexibility. But that's not the case with lower socioeconomic status individuals. The ages of the social clock tend to be younger among people of low socioeconomic status. Speaking of a clock and time ticking away, it is believed by many in the general public that there is a midlife crisis, this idea that time is ticking away too quickly, that in our 40s P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 13 p. 2 or 50s most of us need to make major changes in our lives. This is a myth. It's a myth that stems from certain books written and from some research that occurred decades ago that hasn't been replicated. Together, these sources suggested that there is a lot of turmoil experienced during the 40s and 50s, especially among men. But the observations made for the book and for the research were impacted by the historical context. The men who were part of the study at the time were actually entering midlife in the early 1970s when there was plenty of disruption and change going on in America. This is about the time when their children were being influenced by the youth counterculture and are starting to rebel, and then the women's movement was occurring as well so that wives were less likely to be satisfied with the traditional division of labor that had been so common prior to that time. We now know that most midlife adults are functioning very well. They may make adjustments in their lives, they may change jobs, they may get a divorce, get remarried, pursue a new hobby…but that's usually just them examining other facets of their identity, not making some kind of radical overall change. Some people do have what we consider to be "crises" in midlife, but the people most prone to having crises in midlife are those who were prone to having crises earlier in their life. It's probably more an issue of personality than it is of development. How about personality? To what extent do we stay the same across adulthood, and to what extent do we change? The study of personality is focused more on continuity. That makes it different from the stage-based studies of Erik Erikson. Our personalities are influenced by genes. Think back to infant temperament. Many of our basic personality characteristics correlate with infant temperament, but genes are not the end of the story. Our experiences, the environment we grew up in, certainly has an influence as well. The big five personality characteristics have been identified as the most standard and fundamental personality characteristics, not just in the United States, but across the world. Openness, conscientiousness, extroversion, agreeableness, neuroticism–these are the big five. Openness reflects a willingness to try new things. Conscientiousness refers to discipline and being orderly. Extroversion is a characteristic involving how comfortable we are and interested we are in spending time with others; it also relates to an overall energy level and an interest in being out among others. Agreeableness is about how warm and friendly and humble person is. And neuroticism deals with negative emotions and high anxiety. We don't see a lot of change in the big five across adulthood. In fact, our personality characteristics have an impact on the kind of environment we create for ourselves. Think about how personality ends up having an impact on the context that we find ourselves in. Our personality drives us and influences the decisions that we make. Those decisions in turn create an environment, and that environment then begins to influence us as well. The unique context that each of us carves out through the decisions driven by our personality is referred to as the ecological niche. We help shape our environment…and the environment, in turn, reinforces our personality characteristics. Yes, it is true that sometimes major life events can have a strong influence on personality, but the more common finding is that life events tend to reveal our basic personality characteristics. This is referred to as the accentuation principle; the idea is that an extroverted person who finds herself facing a difficult or challenging situation tends to become more extroverted. She tends not become suddenly introverted. This accentuation principle is part of the reason why we see continuity in personality. What about if we've experienced a terrible awful life event, some traumatic emergency or injury? At first, you'll see a dip in people's coping–that they are having a hard time and P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 13 p. 3 that has impacted them, someone who's normally outgoing and cheery may become more withdrawn and quiet–but, over time we see a gradual return to the pre-event personality. It's like we have a personality set point on the big five and, if something terrible happens or something absolutely fantastic happens–like winning the lottery, we experience a brief change that then fades back to the personality set point. Sometimes there are slight changes in the big five from the ages of 25 to 65. As one example, we see a decrease in extroversion across adulthood, a slight decrease. But we still keep our position relative to others. That means that a person who was really super outgoing at age 20 is still going to be (more than likely) more extroverted than the rest of his friends at age 80, even though his personal level of extroversion has decreased slightly. It's the same thing with openness and neuroticism: both tend to decrease slightly. But agreeableness and conscientiousness, if they change, they tend to increase slightly. But in all of these cases, our position relative to others stays about the same. In regards to gender, people tend to think men and women are so different. We have a whole self help industry built upon the idea that men are from Mars and women are from Venus. But there are more differences between people in general than there are between the genders, and those differences relate to aggression (which men show in greater quantity than women do) and nurturance (which women tend to show in greater quantity than men do). It's unclear how much these personality differences are due to genes or environment. Some evidence from research suggests that as we get older we see gender convergence where men and women become more alike in personality than they were when they were younger. Men tend to adopt more feminine characteristics, like being more conforming, and women tend to become a little bit more assertive. Intimacy and Generativity Let's take some more time to go back to those stages suggested by Erikson and fill them in with the research we have on adults and their relationships and the contributions they make. Intimacy: we all need to be connected to others. In fact, good relationships are strongly correlated with happiness. People often live their lives thinking that money and health are the big correlates of happiness, but actually it is good relationships. And the social convoy is the group of people that are important to you. Whether they are family or friends, these are the ones you feel most close to that come along with you for this ride that we call life. Friends are people we have chosen specifically. With friends, we basically control who we let in, and we tend to let in those with whom we share a lot in common. Our friends are usually of a similar age and a similar background, and we're going through a lot of the same things at the same time. We can provide each other with advice and with perspective. As we age, friendships get stronger and the problems in our friendships tend to decrease over time. Also, we tend to stop caring so much about maintaining those relationships that don't bring us happiness. We get a little pickier and a little more choosy as we age, which also leaves us with friendships that are the closest ones and the ones that make us feel the best. Obviously, family is another important source of support. It's obvious how important family is when we are young, especially our parents who literally have to raise us and protect us and teach us, but those family bonds remain important even between adult children and their parents. On both sides of that relationship there is greater happiness and satisfaction when the adult children are functioning well on their own. When there's dependence, such as parent and adult child living together, there tends to be less P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 13 p. 4 closeness in the relationship. And maybe that has something to do with the factors that led to the adult child or the parent the unable to live independently. Even if adult children are living separate from their parents, their parents still function as parents. They often still help out, offering time, sometimes offering money, even when it's not requested. You can think of parents as “parents on tap” -- there and ready to give support when it's needed… and even when it's not. All that I have just described, of course, is from a nation with a certain ideology of independence. But dependence doesn't have such a negative connotation in other cultures, of course, like Asian nations. In China, dependence is actually a positive trait. Within those families, people who have a dependent relationship with their parents or with their adult children are less likely to see this as a burden, and it doesn't have the same negative impact on their overall happiness and well-being that it seems to have here in Western cultures. When dependence is paired with sacrifice, being willing to sacrifice one's own freedom and desires in order to meet the needs of the family, this is referred to as familism. It is particularly common among families in United States of Latino background. Of course, familism can bring with it a certain amount of stress, but at the same time it also tends to indicate a close-knit family that's able to help each other out and support each other through difficult times. Within families, most of us have siblings of some kind. As we grow old with our siblings, there are changes in the relationship that are common. They tend to be good changes, though. You may not have gotten along very well with your brother or sister when you are teenagers, but chances are (if you're like most of us) as you grow older relationships between siblings grow stronger. There are gender differences, though. Sister relationships tend to focus more on emotional aspects, like emotional support, whereas brothers tend to help each other out more in terms of practical support, doing things for each other. You don't have to be blood relative to have someone who feels as close to you as a brother or sister. Fictive kin are friends who become sort of adopted into a family, and this might happen because the person is not accepted or doesn't relate to their family of origin and becomes adopted as a nonbiological member of a different family. Something that most of us will do (the vast majority of us will do) at some point in our lives is get married. 90% of us will be married at one point in time or another. How happy does marriage make us? Well, it depends. If you look the broad statistics, people who are married who are a little bit happier, a little bit healthier, and tend to have a little bit more money. But these differences are not very large, and there's a lot of variability that depends upon the two people and their expectations and the things that are going on in their life. Obviously, happy marriages contribute greatly to a person's overall satisfaction and happiness. But what are the factors that influence that happiness? There are some influences, like cohort changes. Today, men and women do not have such distinct traditional roles in a relationship, or in their family, and that helps in some ways because it takes some of the pressure off of men. They don't have to carry the entire financial burden for the family, and it takes some pressure off of women that they don't have to be 100% in charge of the caregiving, especially when many of them are also working full time as well. This can be a source of happiness, but the other thing that it does is it tends to take away some of the glue that the mutual dependency of traditional roles used to provide for a couple. Think of the traditional roles. If a couple is accustomed to mom being at home with the kids and dad being the sole source of income, both have a strong P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 13 p. 5 investment in making the marriage stay together. In some cases, that might help couples work harder and help them increase their happiness, but in other cases it might lead to couples staying together just for the sake of the kids. In other words, there are cohort differences but they don't point in one direction. What about over time? What happens to marriages over time? Marital satisfaction tends not to change to radically. When children are born, and when children are teenagers, marital satisfaction dips a bit. We do see a decrease in marital satisfaction. But, after the children have grown up and have left the home, this is the time referred to as the empty nest. Marriage actually tends to improve once the couple is living in the empty nest. There's a stereotype that the parents are depressed, especially a stereotype about moms not being able to handle the nest being empty. Well, these days anyway, we find from the research that marriages tend to improve slightly once the children are out of the house. Now the married couple has more time together, just by themselves. They also are more likely to have less stress -- less emotional stress, which parenting often involves -- and less financial stress as their adult children are becoming more financially independent. By the way, most of the findings I just described are about the same when it comes to committed relationships between homosexuals. A couple of differences have emerged so far. For example, homosexual committed relationships tend to involve more equity in the housework and childcare aspect of the relationship. That means that both members of the homosexual relationship tend to contribute equally to house care and child care. Also, in a homosexual committed relationships, both members tend to spend more of their time with friends. All of this talk about friends and committed relationships, but we know that not all relationships last. However, the divorce rates in the United States have actually decreased just slightly lately, so that we have slightly less than 50% of couples divorcing. You have to keep in mind that many of these divorces are from second or third or fourth marriages. In fact, 50% of the marriages today in the United States are second marriages or beyond for at least one member of the couple, so that means that only about 50% of marriages are first marriages for both partners. Does divorce make things better? It depends. Once again, it depends. If the couple had been fighting and had a lot of overt stress and conflict in the relationship beforehand, most tend to be happier after the divorce. If their marriage had just grown distant, kind of like they just lost their connection with each other and didn't feel like they knew each other much, or withdrew from each other, then they tend to be less happy than they expected after the divorce. In fact, distant marriages leading to divorce -- that's the most common pattern in the United States. So what's going on that makes divorce so difficult? A lot of couples hang out and have friends who are also couples, so when there's a divorce there's also a loss of friends. It puts a strain on some friendship relationships. It's also a sense of failure for many people, and it can generate lots of conflict and stress and concern having to do with children custody, visitation, and how the children are handling the divorce. There's also a decrease in income, especially for women, after a divorce. And the research shows us in general that divorce is correlated with children's academic problems and social problems. But still, it depends. For kids, it's better for highly conflicted couples to divorce than it is for them to stay together. Children don't function well when their parents are married if their parents are P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 13 p. 6 having conflict all of the time. Interestingly, in African-American families we see the children of divorce actually have less trouble than in Caucasian families. And it depends on how young we were when we got married. These days it's the case that the older the couple is when they get married, the lower their likelihood of getting divorced. Perhaps this is because today it's very important to have a more refined understanding of your individual identity before being ready to get married. But in the past, actually,, when the social clock was different it was the opposite: those married at older ages had a higher chance of divorce. So today, anyway, if you want the odds to be more in your favor, it's better not to get married as a teenager or in the early 20s. That's what the odds tell us, but there are always exceptions. How about generativity? Erikson believed that in adulthood we need to feel like contributing something of ourselves to the broader society. Maybe through the children we're raising, through the work that we do, and through other expressions of the self like volunteering or hobbies. This is not always linked to age. Erikson originally believed it was a midlife phenomenon, and it certainly does become salient in the middle of the years. But for others it's already been a driving force, maybe because it's just part of their personality to think about how they can help others or make some kind of lasting contribution. Most of us express generativity through raising children. It's obvious how much sacrifice and contribution and attention children require. They are completely dependent upon us in their early years, and then it's a constantly moving target. As the child changes and develops, the parents are adjusting and changing, and it's difficult to anticipate what it's going to be like even a year from now. Two-thirds of adults are biological parents and one-third of adults become some type of nonbiological parent (either through adoption, or stepparenting, or foster parenting). The research shows us that the bond between parent and child does not have to be biological to result in attachment. For instance, the research on adjustment among children who have been adopted (and especially those who've been adopted in infancy) shows us that most develop just fine, showing similar levels of adjustment and well-being as biological children. But one difference emerges. Remember how we talked about the myth of the teenage years being such a conflict ridden time, when the reality is that most teenagers and their parents get along okay and, if they fight, it's usually just bickering about little things? Well with adoption there are challenges that tend to pop up in the teenage years because this is when we're thinking about identity, right? And so for the child who was adopted for whom adoption wasn't even a big issue for them when they were growing up, now that they're thinking about who they really are and what they want to be, trying to figure out all those really important identity issues, they may become more interested in locating or spending time with their birth parents. And they may become more rebellious toward their adoptive parents. That's the case for some but, for most families with adopted children, adjustment and happiness are the norm. We care for our children, but we also may begin caring for aging parents as well. Couples today have fewer children than couples in the past. So there are fewer members of younger generations compared to older generations. Adding to that, we also live longer so that the older generations are (thankfully) likely to be around for a longer period of time. This means that we have more adults caring for their aging parents. Still, most do not have to care for their parents full-time. There's a concept called the P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 13 p. 7 sandwich generation that refers to (usually) midlife adults who may be providing assistance upwards to their parents and also downwards in terms of generational status to their children. It's like they're squeezed in the middle. But is it really a squeeze? Is there a lot of pressure for most midlife adults? The research tells us that this concept of sandwich generation and the squeeze is a bit exaggerated. More often than not, if there's assistance flowing between the generations, it tends to flow downward. It's not common for midlife adults to be doing a lot of caregiving for their parents. The older adults' attention is focused more on caregiving for their children. Even though their parents are aging and may need some help, there still is assistance that flows from the grandparent generation down to the parents, so those aging parents are still providing some support–whether it's emotional or in regards to time–to their midlife adult children. Generativity is also expressed through employment as well. Although the thing that tends to attract us to a certain job in the beginning is income and other goodies like insurance, it's funny because those are not the things that are correlated with our happiness overall. Once we are above the poverty level, happiness is not correlated with income. What matters more is how we feel we compare to others around us. This is called relative deprivation, when we feel like our experience is of a lower quality than it should be compared to those who are around us. When our situation compares poorly to the situation of others around us, that's when we're most likely to be unhappy…and that applies to employment. If all of your friends are at a certain income level and you are way below that level, you may feel dissatisfaction with employment because of that sense of relative deprivation. Income and health insurance and pension plans… all of these are extrinsic rewards of work. They are external factors that may motivate us to work. They are the "things" that we get from doing the work. These catch our attention and seem particularly important in the early years of our career. But there are internal factors as well, like a sense of satisfaction about the work, or a sense that it's important, a sense of self-esteem about what you're able to do. These are referred to as intrinsic rewards of work. These become more and more important as we age and as we spend time in a given career. Those rewards are related to other important factors as well, like how much decision-making power we have on-the-job (in other words, how autonomous we are). Even if we're not making the big decisions, do we have some control over our work situation? Can we decorate our office the way we want to? Do we have some flexibility in hours that we come in to work? These are all factors that help contribute to the intrinsic rewards of work. The career path of adults today is characterized by more change than was common in the past. There's more hiring and there's more firing that occurs for the average adult across their worklife. Even if this change ends up being a good decision, job changes are stressful. They often involve needing to learn new skills, getting accustomed to a new group of people… they may even involve a significant relocation, which could mean changes to friendships, changes in children's schooling, and all kinds of stuff. Our job schedules, our work schedules, tend to be more variable these days than in the past, and only about half of us work a typical 9-to-5 job from Monday through Friday. Flex time is becoming more and more common. Flex time is a work schedule that could be changed to accommodate other responsibilities in the person's life. Perhaps your supervisor doesn't mind if you leave early on Fridays as long as you stay late other days in the week to make up for it. Or let's say a new mother has worked out a schedule where her day begins at 6 AM but she's finished at three. Or within the workplace, P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 13 p. 8 people are permitted to work 10 hour days on four days of the week, having a weekday off. Of course, not everyone has access to flex time. It depends greatly on the industry. Is the industry one that can allow there to be flexibility in the schedule? Sometimes it also depends on seniority. Adding to the flexibility of our work life these days is telecommuting. Telecommuting is simply working at home and having a connection to the office or to other employees through technology like the telephone or the computer. The thing about telecommuting is that it's good for family relationships, in that parents are more readily available to respond to the child's needs, but then that could be bad for work productivity because there's the potential for interruptions. When we are interrupted, our work tends to be less efficient. Furthermore, although telecommuting may bring with it all kinds of rewards in terms of spending time with family and being able to wear your pajamas while you work, there there is the negative that people may begin to miss the intrinsic bonuses that come with working in an environment with other people,, and seeing other people and interacting with other people...face-to-face. Coping with Stresses A stressor is just something that causes a feeling of tension or strain or concern in a person's life. What is a stressor to one person may be quite different from what is a stressor for the next person. The combined effect on our physical bodies from both physical and psychological stressors over time is referred to as allostatic load. Allostatic load is measured physiologically but, as I said, it can involve not only the stress of a physical illness, but also the stress that's occurred to the body as a result of psychological stressors. When we are worried or upset, our hypothalamus in the brain triggers the release of stress hormones. These stress hormones rev the body up into a feeling of fight or flight that is designed to help us survive the stress. But among humans what ends up happening sometimes is we're not actually facing a real threat to our lives, like a bear that's trying to eat us. No, but we may be having that same physical reaction because were worried about something that's going on, because we live in a noisy and dangerous neighborhood. or every day we have some fear about our personal safety. That means that there is a constant (or at least a frequent) flow of stress hormones that have been triggered. This can eventually wear and tear on the body, reducing immune functioning and leaving us more vulnerable to becoming sick. A combination of aversive influences has a cumulative effect. That's why we call it “load.” We load on these factors and the more aversive influences there are, the greater our vulnerability becomes to illness...both physical and mental. Our body is designed for some stress. In fact, our organs have what's called organ reserve. That's the sort of backup plan and backup capacity that are organized to handle stress in the moment and then recover from it and go back to homeostasis. Our lungs have organ reserve, for examples, so that we can push ourselves and run really hard and really, really, really, really fast in response to an emergency or something. And then we recover. When what were dealing with is an emergency of some kind, we actually refer to it as recovery reserve. The more emergencies we face, the more we put stress on that recovery reserve…the more wear and tear our body goes through, and the more vulnerable we are. What can we do to try to decrease our physical experience of stress? We cope, right? There are two basic kinds of coping: problem focused coping and emotion focused coping. Problem focused coping is focused on the problem. What that means is that our P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 13 p. 9 goal is to change the situation, to take charge and to make the things that we can control somehow different. This can be stressful. It's like we're fighting hard. Maybe we have some kind of problem at work and we are fighting it and we're trying to change it. And you know what? Sometimes a problem focused approach is very effective. But the trouble is when we don't realize the need to let go of the problem focused coping and to switch into an emotion focused coping mode. That's when we focus instead on changing our emotional reaction or our cognitive interpretation of the situation. In other words, we try to reinterpret what's going on, to relax, to change our goals. This is most critical when we are up against a problem over which we really don't have control. One of the benefits of aging is that as we move across the adult years we get better and better, most of us do, toward making that switch to emotion focused coping, recognizing, “okay, you know what? I'm not going to fight this so hard anymore. How can I change my perspective instead?” In addition, there's a gender difference. There are physiological reactions that tend to vary slightly whether we are male or female. This also can be seen as related to the different coping strategies. On average, when men are stressed out they tend to have more of a fight or flight reaction, and this is gearing up to sort of do something, right? That's more of a fit for a problem focused approach. Whereas for women, when they feel stressed out, the physiological reaction (which involves oxytocin in addition to the other hormones) leads to more of the tend and befriend reaction, which is more conducive to emotion focused coping. Now, men and women use problem focused and emotion focused coping. It's just that this gender difference that has been connected to different biological reactions to stress suggests that men and women have a dominant mode of coping that perhaps comes a bit more naturally to them. Social support is very important in helping us manage and reduce allostatic load. Whenever we are able to talk to people who care about us, and for whom we care about, that feeling we get actually corresponds with lowered production of stress hormones. There is a physical difference among those who have good social support, compared to those who are more isolated. It's important to have intimate relationships, emotionally intimate relationships. And it also makes a difference how we think about our situation. Of course, this fits right within emotion focused coping where our interpretation matters a lot. People have very different interpretations of the events of their lives. These interpretations can be influenced by past experiences. They can be influenced by personality and by ideology. Consider someone who is prone toward neuroticism. Perhaps since their early years of life they have tended to see things in a really negative light; they've tended to be insecure and very emotionally reactive. When something happens to them, let's say they're stood up on a date, that would be hard for most people to handle. We don't like to feel rejected. But for the person with the tendency toward neuroticism to begin with, they are likely to interpret that situation in a much more negative way, thinking that it has something to do with their general failure or that they're never going to meet anyone. This tends to be a long-lasting kind of interpretation that colors many of their views of the things that happened to them. A chronically negative kind of interpretation of the things that are happening in one's life is going to result in more stress experienced by the body, which will involve more stress hormone release and will contribute to allostatic load. Our thinking and our interpretation matter. That doesn't mean that everyone should just put a smile on their face and act as if they're not bothered at all. That is denial. That's not really emotion focused coping. We won't be able to completely prevent ourselves from getting stressed out simply by adopting a rosy interpretation of everything, but we can catch ourselves and notice that we're sliding P16 Podcast Transcript, Amy Himsel, Ph.D. Chapter 13 p. 10 down to a very negative place and seek out some help: talk to a friend, go to a therapist, do something to help us gain some perspective. That is also a part of emotion focused coping. Chapter 14.1: Late Adulthood – The Aging Process Most of us donʼt know much about older adulthood and what we think we know is often not going to line up with the reality thatʼs shown to us through research on lifespan development. A lot of what you have to learn about older adulthood is actually good news, or least better news that you might have anticipated. At the same time, though, it is difficult to categorize older adulthood and speak about the kinds of experiences that most 60 year olds have, or most 70 year-olds have, and so forth. Why? Well, our diversity as human beings in terms of our abilities and our health and our capabilities tend to only become greater as we age. As a population, we see greater diversity, for example, in cognitive scores in older adulthood than we see in any other time of the lifespan. We see greater diversity in physical health. Knowing that somebody is 70 years old tells us very little about what we can expect of them, from their cognitive development to their physical health to their psychological well-being. So we should try to curb our tendency to stereotype older adults and to consider the impact that stereotypes have on the functioning of older adults. Ageism When we believe in the stereotypes of older adulthood and when we treat people as though they are conforming to those stereotypes or as we expect them to conform to those stereotypes, we commit ageism. We misunderstand a lot about late adulthood in the United States. And we can see this in the stereotype notions in what it means to be an old person. We assume that old people are slow, hard of hearing, depressed, and bitter and sad about being old. For example, we can see this in the way people often interact with older adults, talking to them in a really loud voice, speaking very slowly. This is elderspeak. Itʼs the way that ageism comes out in the manner in which we speak to older adults. Those that use elderspeak I think often have good intentions. They may not realize though that their use of elderspeak has an impact on older adults and older adultʼs sense of themselves. And although it is true that our hearing declines as we age and that we suffer many other losses, it is also true that our experiences can be affected by the way that weʼre thinking about things. Imagine yourself as an older adult. If you have concerns about your aging process and you have concerns that your hearing is starting to decrease, for example, this concern, this fear of “oh no, Iʼm starting to act like an old person” can make a person feel upset and can actually impair their performance. This is stereotype threat. We see stereotype threat in many cases where thereʼs a negative stereotype that we may be afraid of confirming through our behaviors and that fear itself can be a factor that diminishes our performance. Think of an older adult who gets really upset when he canʼt remember something little, letʼs say like somebodyʼs name. Instead of just, you know, brushing it off, like oh whatever, if he becomes really upset every time that kind of thing happens, the act of being anxious is actually depleting his brain of the ability to think well in that moment. Just like if you are sitting down to take a test, and you are anxious about the test, your performance is likely to be impaired at least somewhat. And the research bears this out when it comes to older adulthood. Ageism is a stereotype that many older adults are afraid of confirming. But paradoxically, that fear of confirming a stereotype increases the chances that they will not be able to hear well, or will have continued trouble with memory. Interesting research has been conducted that looks at stereotype threat in older adults in a way that lets us compare different groups. In China, for example, thereʼs much less of an ageist stereotype. In fact, the elderly are revered and respected; to be getting older isnʼt look as such a negative as it is here in America. These cultural differences are paralleled interestingly in stereotype threat based upon when Chinese immigrated to North America. Those who moved to North America earlier in their life experience a steeper in decline in their abilities due to stereotype than those who immigrated only recently. This suggests that those that have been in North America for a long time have been here long enough to have been impacted by the ageism that is so common. That stereotype and the fear of confirming this stereotype can exacerbate but typical age related but small declines in memory that we see in older adults. Peers and expectations have a influence on our abilities. And please donʼt mistake this as suggesting that we can somehow avoid aging. I think Americans would very much like to figure out how to avoid aging entirely. It isnʼt a matter of simply thinking yourself young. We canʼt stop aging. But we can get better at understanding other influences that can increase the rate of aging beyond what it would have been otherwise, and stereotype threat is an interesting angle at which to look at this issue. Just how old is somebody before they are consider old? It depends on a lot of things. Scientists like to break down older adulthood into three categories: the young-old, the old-old, and the oldest-old. These categories are not directly tied to age. They have to do more with the ability to live independently and the presence and absence of disability. The young-old for example are active. Theyʼre involved. They donʼt have difficulty meeting their own basic financial needs. And they can live independently without needing assistance in the home. Most people who are over the age of 60 would fall into the category of the young-old. The old-old are still living on their own. They might be living with a spouse, but the point is they can live independently but theyʼve suffered some major setbacks in their physical health and their cognitive health, or in their social experience. And among the old-old, they still maybe caring for a spouse or for some other loved-one at the same time, but itʼs clear that their health is on the decline and that they are having a more difficult time with it. The oldest-old are unable to live alone anymore. They have to have assistance from others because of their physical aging, their cognitive aging, or other problems with their health. Remember though that these categories are not simply lining up with age ranges. Itʼs true that most of the young-old are between the ages of 60 and 75, but there are some old-old among those age 60 to 75 and there are some of the oldest-old already in that age range as well. You may find a person who fits the category of young-old who is well into her 80s. In recent decades, we have been increasing our lifespan. We live longer than we used to, and at the same time we are having smaller families now than what weʼre used to. Itʼs resulting in a change in the structure of our population. For many, many decades, it was common to see whatʼs called a population pyramid. If you look at the age distribution of people in the United States and in other countries as well and the pyramid is wide at the bottom and think of that as the young people. And as we move to the top of the pyramid, weʼre moving older and older up the lifespan so that a pyramid is more narrow at the top than at the bottom right? And for a long time, this was how it was for us as well and still is although itʼs changing. There are more younger people than older people. And itʼs still the case that there are more younger adults, for example, in the United States than older adults. The thing is that older adults are growing in their population at a staggering rate. The population pyramid is turning more and more into a square here in the united states and it already is more of a square in some other countries. The issue that arises then is about how to take care of the older adults who need care. The dependency-ratio is a statistics that tells us about how many independent living individuals there are in a given population compared to those who are dependent. In other words, how many of the people in our population who can care for themselves and how many are reliant on others for their care. Currently the dependency-ratio is 2 to 1, two independent people for every one dependent person. But itʼs projected to change and to change pretty rapidly. Itʼs hard to predict but some experts are thinking it may even flip so that we have one independent adult for two dependent individuals. Now becomes an issue, a pretty significant population issue of how to take care of the aging population. Remember though, that some of those age 60 and older are still independent. We sometimes assume that older adults need more help than they really do need, especially when weʼre thinking about the population at large. But think about the older adults that you know, think about people who you know that are over 60 years of age, how many of them are living independently. Iʼm sure quite a few of them are living independently and some of them may even be caring for others as well as being able to continue caring for themselves. The challenges of the pyramid shifting and the dependency-ratio changing has more to do with the way we are caring for the oldest-old, who are the ones most likely to be dependent on others for help. Remember morbidity, that was a statistic we talked about, it reflects the rate of disease. As we age, we are going to probably experience more morbidity. The length of time we spend being ill before death thought, has decreased. This is referred to as the compression of morbidity. It means that we spend more years of our life in relatively good health, and a shorter span of years before we die in poor health. Compared to our ancestors, this is a dramatic difference. In the past, human beings were likely to have an extended period time with issues of morbidity, but for us today, whatʼs more common is that we have more healthy years, but then the decline we have before death tends to be a steeper, more rapid decline. Think again about the people you know who are age 60 or older. Do any of them need some assistance with some of their aging senses? You know like, could they use some help with their eyesight. Could they use some help with their hearing? And are any of those individuals reluctant to get help for these kinds of problems with their declining senses? This is common. One of the downsides of the fact that weʼre feeling better for longer and having a compression of morbidity is that it can lead us to deny the kinds of problems that we are starting to have with our sense. Perhaps someone is struggling to be able to hear well but they donʼt want to get a hearing aid because in their mind, hearing aids are for old people. And they have a fear of aging. They would rather suffer through dealing with their limited hearing than to admit that their hearing is aging and get a good hearing aid. The problem is then these individuals are going to have difficulty in conversations, theyʼre going to need the TV cranked up really, really loud, or they may withdraw from conversations a little bit more. And then in response the people around them may begin to use elderspeak, speaking to them loudly and slowly, which only make older adults only feel only worse about their age. And the cycle continues of the denial of the aging senses. Even if an aging adult is fully aware of their aging senses and they want to do something about it, it can be really difficult because of how expensive these technologies can be and how many hoops they have to jump through to see if Medicare will pay for something and to make appointments and to get to appoints…there are lots of steps before they can assess the technology they need and it can feel overwhelming. The environment in general, here in the Unites States at least, doesnʼt help much either. Iʼm always frustrated when we go out to dinner with some of our older friends and weʼre at a restaurant where they have the music turned up so loud that we have to shout at each other. Why does the environment have to be that way? Do we really have to have the music up that loud and the lights down so low? Frankly, I get a little concerned because I think this is a concern that is a trend that is increasing. I notice it even in myself. Iʼm not anywhere near 60, but I can only take so much time shopping in H&M with the music up so incredibly loud. We could make changes and we really should make changes in the environment that could help adults manage their aging senses. We should remind ourselves that if weʼre lucky, weʼre going to get to that old one day and we will benefit from it as well. Health and Sickness Remember the concept of senescence? Thatʼs a biologically programmed process of aging that begins even back in late adolescences and early adulthood, but we donʼt notice a lot of that aging. We donʼt recognize the senescence thatʼs occurring until we get older. We start to notice it more in midlife, and we start to notice it the most in older adulthood. The physical aging process can be understood in terms of two basic types of aging: primary and secondary aging. Primary aging is universal. We all will experience it if we live long enough to age. Hearing loss would be one example of primary aging. But thereʼs secondary aging which has to do more with whatʼs unique to each individual based on their genetic make-up and also the experiences theyʼve had in the environment theyʼve grown up in and aging that comes from dealing with diseases thus far. Primary and secondary aging are often going on at the same time. Take heart disease for example. Certainly, secondary aging is involved. Some people are genetically predisposed to heart disease. Some people have been very physically active or theyʼve had a poor diet and these can make heart disease more likely. But at the same time, as the body ages on its own, which is primary aging, we also become more susceptible to diseases. Sure, sometimes people experience heart disease as early as their 30s, but the risk of developing heart disease increases with age. Why? One reason is because as we age, our blood pressure tends to increase. Any kind of secondary aging related to heart disease will be compounded by the primary aging thatʼs going on. By the way, this is one reason why we have more cancer today than weʼve had in the past. In fact, our rates of cancer in the United States are much higher than rates of cancer in the developing world. But the reason for that is mainly because whenever a population lives longer, their chances of developing cancer increase. Ok, so we canʼt avoid aging entirely, but what can we do to stay as healthy as possible? Nutrition and exercise, I donʼt think these are mind blowing concepts, but itʼs always good to be reminded of how important it is to take care of our bodies at a basic level. Itʼs also important that we understand the changes we go through as we age so we can adapt accordingly. We have a decreasing metabolism as we age so we donʼt need as many calories as we used to but at the same time we need to make sure weʼre still getting the proper balance of nutrients. Digestion is likely to become more problematic as we age so we have to take care about the kinds of foods that we choose to eat. This is important also because the brain, the physical brain, functions better when itʼs properly nourished. Exercise, exercise increases the length of our life that we will live without disability and without disease. However, the challenges that come with the physical aging process can make exercise more difficult. This can be another area where our feelings, our personal feelings about ageism, can get in the way. Yeah, it can be difficult if you used to run several miles a week and you can no longer maintain that because of aching joints, problems with your knees. But some kind of movement is better than nothing at all. In fact, some kind of movement is much, much better than nothing at all. I know a woman who is 91 and goes to the gym several times a week. She gets into the pool and itʼs a heated pool and she does some basic movement exercises. Itʼs a pretty low-key workout for someone who would be younger, but for her, itʼs enough to make a big difference in her physical health. And she notices if she hasnʼt been for a while that she starts to not feel so great. Adjusting and learning how much exercise is enough but not too much is the goal. Being careful about this can also help combat one of the other things that can keep older adults from exercising. And thatʼs the fear of falling. So if the fear of falling and the difficulty facing the realities of aging are getting in the way, that can have a significant, negative impact on our physical health as we age. Just how long are we going to live anyway though? How long can we possibly live? Maximum lifespan is a measure of how long the species can live. Itʼs like a limit and right now for homosapiens, for us, it appears to be about 122 years of age. The main influence on maximum lifespan is our genes. Our cells canʼt keep dividing forever. The average age of the population has to do with the average length of life in a particular group and you can look at it by gender, or by ethnicity, by nation. Here in the United States, the average life expectancy is 75 years of age for men and 80 years of age for women. Very, very few of us are going to live beyond the age of 100. The interesting thing is, though, that the population thatʼs growing the fastest in the age distribution would be centenarians – people who are 100 years old or older. Now donʼt assume that theyʼre all in terrible health because theyʼre not. Not all of them are in poor health. And perhaps, I donʼt know, if itʼs more important, at least itʼs important, but centenarians do not show any decrease in their life satisfaction or their basic contentment with life, even if they have physical limitations. So we canʼt stop aging. And we might even make things worse if we keep trying so hard and insisting we can do so. Itʼs better to make the years that we have as healthy and as full of life as possible then to simply try to extend the number of years that weʼre here on planet Earth. Chapter 14.2 – Late Adulthood – Thinking in Late Adulthood In this episode, we are going to talk about the kinds of changes that happen to our thinking in older adulthood. But there are many different possibilities. Thereʼs the kind of development thatʼs typical and usual, but then there are also unusual cases in both negative and positive ways in which our thinking can change as we get older. Typical changes Remember primary aging? This is the kind of physical aging thatʼs universal. It happens to us all. Well, that includes brain aging. There are general patterns that we see with the brain across adulthood and how it ages but thereʼs also a lot of diversity in how each individual person in older adulthood experiences brain aging. One thing that we do know is that we see a general slowing down of the brain. The brain becomes slower to process information. The brain works at a less efficient pace. Itʼs not all bad news though. The older adult brain can still create new neurons and can still make new synapses between neurons but it happens at a much slower rate. Neurotransmitters are also produce at lower rates as well and that effects the speed of transmission. On top of that, myelin which is the coating around the axons of the neurons that speeds impulses - that myelin sheath begins to thin across the older adult years. Brain aging goes along with a decrease in working memory capacity and this means it takes longer for older adults to process information and to respond to information - information coming in from the senses. So if someoneʼs asking an older adult a question, the older adult is taking in that auditory information and then being able to respond to it, that process is going to take longer on average. Another change that we gradually across older adulthood is that the brain does get a bit smaller. For most of us, this isnʼt a dramatic change. Starting in our 60s, the brain begins to shrink and by 80 year of age or so, we may have lost about 5 to 10 percent of the total brain volume. It also tends to impact certain areas of the brain more than others. The areas of the brain related to memory and the area related to being able to solve problems, the prefrontal cortex. Technology allows us to take a look at the older adult brain as a person is actually trying to come up with the solution to a problem that weʼve given them. And interestingly, the results show us that older adults are activating more areas of their brain when they are solving a problem. This may be showing a compensatory process. Remember selective optimization with compensation? We may without our knowledge be calling upon other areas of the brain to make up for some of the deficits that weʼre experiencing but itʼs also possible that this scattering of use of different parts of the brain may have something to do with the prefrontal cortex becoming less efficient. The prefrontal cortex is the central executive of the brain, kind of like directing an orchestra, telling which part to do what and when. If the prefrontal cortex is losing its efficiency somewhat, then perhaps the processes of the rest of the brain are becoming a little more chaotic and that maybe what weʼre seeing. Perhaps itʼs a combination of the two, we just donʼt know yet. Using the information processing approach, lets think about each step along the way from taking in new sensory information, storing it, using it, and coming up with answers or responses when we need to. Input is a process of bringing sensory information into the brain and our input as we get older is reduced. We donʼt pick up the same level of detail of sensory information that we used to. And we tend to fill in the gaps with reasonable guesses. And our guesses might be incorrect or not quite on the mark, which can have a negative impact on our ability to solve problems. It isnʼt clear yet though whether the problem is with the actual sense organs and getting the information into our heads or what our brain does to that information once it comes into our head. Most of the time we hope to hold on to and store a lot of the information that weʼre encountering and storage is a part of the information processing system. In everyday words, weʼre talking about memory - how much do you have appeared to have stored in your brain. And the stereotype of ageism of course is that we canʼt remember things anymore and then if weʼre stressed out about aging then the fear of “oh my God, Iʼm losing my memories” can make it even harder to remember things. The reality is that some areas of our memory are functioning better than others at this time in the lifespan. For example, our memory for vocabulary, which is called semantic memory, it tends not to suffer much as we get older, but our memory for the details of events, and this is called episodic memory, does tend to decline with age. In addition, our ability to remember where we heard something or where we learned something or who said something also tends to decrease and this is called source amnesia. With the slowing down and the lowered capacity of working memory, multitasking becomes pretty difficult. We need to do things one at a time and we need to give ourselves more time when weʼre growing older. But we can often do the task very well if this is the case. Iʼm thinking about one of my grandmothers-in-law, “I can do everything. It just takes me longer to do it.ʼ Luckily she has the attitude where she doesnʼt put her down about it so she simply will take longer to do many of the things that are important to her. This finding that with time and focused attention that we donʼt show that declines in our cognitive abilities becomes particularly important when we look at the research in cognition in older adulthood. Many of the tasks that scientists so far have asked older adults to participate in arenʼt the kinds of realistic, everyday thinking tasks, that they actually have to do. itʼs more these sort of random and rapid memorization of nonsense syllables, for example. Thereʼs a reason for this. You know, scientists have often felt that if you give someone this more of a pure measure of cognition that isnʼt impacted by their daily experiences that youʼre really seeing whatʼs going on with the brain. Thereʼs truth to that, yes, but another truth is that thereʼs a context in which we live our real lives, so if we really want to understand how older adults are really functioning in their real lives, itʼs important to develop measures of cognition that have more ecological validity than memorizing a list of nonsense syllables. Ecological validity can be applied to any construct we are interested in measure, but when we are talking about memory, ecologically valid measures would be measures that are similar to natural context that people find themselves in, you know, actually having a conversation or responding to questions in a conversation. These are the kinds of tasks where older adults tend to perform the best, they perform much better in these real life scenarios than they do in the sort of artificial set up in the laboratory and so far a lot of the research have compared young adults memorizing nonsense syllables to older adults and you see big, big declines, but you donʼt see as big of a gap between younger adults and older adults when the problem solving tasks are as similar to real life as possible. And where older adults have more time and can focus their attention on the task itself. Dealing with all of the input that can come in from our sense and knowing what to do with it relies on the programs that weʼre running in our brain. Programming has to do with controlled processes. This is the prefrontal cortex, the central executive of the brain. Itʼs the conductor of the orchestra thatʼs keeping all of the instruments playing together and signaling when this section should start or stop to play and whatʼs going on here then is that weʼre picking strategies for solving problems, to bring it back to the brain. Take it away from the music analogy, we are making all kinds of decisions about what to pay attention, about strategies for remembering things, about how to approach a new problem, and controlled processes tend to become more of a challenge as weʼre aging in large part because of the prefrontal cortex. Remember that is where we do see loss of the brain, we do see decline in brain aging, and so it makes sense that we have difficulties with this part of information processing. Programming involves not only with how we deal with new information coming in and the strategies for hopefully retaining that information, but there are also programs that weʼre running in our brain for how to retrieve information we have learned before. And memory is a process of retrieval. This can also help explain why, for example itʼs harder for older adults to remember the accurate details of the episodes, the events that have happened in their lives. This is called episodic memory. In contrast, remember vocabulary tend not to decline much at all, if at all, and that doesnʼt require as much of a strategy to retrieve if you know the definition of a word, itʼs pretty straight forward in pulling that out again. Where we often will pay most attention especially in our daily lives, is on the output component of information processing. What can I actually remember if Iʼm taking a test, how do I perform on that test? Output is the answer we come up with, the solution to the problem that weʼre trying to solve and this is what intelligence tests are attempting to measure. Or at least theyʼre measuring a part of that cognitive output. A part most relevant now would be those aspects of our intelligence that rely most on information processing speed. Information processing abilities. One example would be verbal fluency, being able to come up with different combinations of words on the fly, for example. That would be one example. Spatial reasoning. Fluid intelligence. These are closely related to information processing skills and we see decline in these areas of functioning starting around age 60 or so. But, of all the declines that Iʼve mentioned, we are unable to prevent them from happening entirely, but weʼre also able to slow down the slowdown. In other words, try to make that lost occur as slowly as possible by keeping ourselves physically healthy and also by exercising our brains and keeping our brains active. Atypical Changes Although its hard to categorize older adults as having a typical or atypical experience because older adults are a very diverse group and because age doesnʼt necessary correlate with functioning, some experiences are more common than others. In this section of the podcast, we are going to talk about the unusual experiences that occur with thinking in older adulthood at both the high end and the low end of functioning. A small proportion of older adults have cognitive impairment to such an extent that their everyday activities are disrupted. Their thinking and their behavior is greatly impaired. This is referred to as dementia. About 14% of older adults over the age of 70 have some form of dementia. The most common form of dementia is Alzheimer disease. With Alzheimer disease there are plaques and tangles that have built up in the brain over time that interfere with the ability of neurons to communicate. The plaques are made up of the protein beta-amyloid and they kind of gunk-up the areas between neurons. And the tangles are made of the protein tau and these are thin strains that are sort of twisted and it also gets in the way of neuronal communication. The plaques and the tangles are particularly likely built up in the area of the brain essential to processing memory and that is the hippocampus. But eventually, over time, the impairment spreads throughout the brain. If Alzheimer disease occurs in middle age, we know now that it is due to a dominant gene and it progresses very quickly within 3-5 years. In older adulthood, though, on the other hand, we do know of some genes that correlate with Alzheimer disease, but we donʼt know enough to make any kind of guarantee or predictions. Itʼs tough because although there are several genes that have been found to correlate with Alzheimerʼs, in no way do we know if those genes cause the disease and if so, if other factors interact with the genes, or whatʼs going on. And it presents a problem for people because they may want to know whether or not they have those genes, but finding out that they have one of those genes can make them particularly anxious and concerned. This could lead to further impairment because of the anxiety thatʼs going on. So itʼs best at this point to say yes, thereʼs a genetic component, but thatʼs about all we know. The disease progresses like rewinding a tape. The most recently learned information is the first to go and then it gradually gets worse year after year until the person is no longer able to recognize other people or to recognize him or herself in the mirror. And eventually Alzheimer disease will end in death if other illnesses havenʼt already caused the death, about 10-15 years after the first signs of Alzheimer disease. Another form of dementia is vascular dementia. It used to be called multi-infarct dementia and sometimes still is. This is the result of tiny strokes, mini-strokes that have occurred over time that caused a bit of damage to a specific spot in the brain and then if you have several of these causing damage to the specific spots across different parts of the brain, dementia can develop from that. Vascular dementia can also occur along with Alzheimer disease. You can have a bit of both. Frontal lobe dementia is perhaps one of the most difficult dementias to cope with as a family member or a loved one because of the part of the brain areas it tends to target. With frontal lobe dementia, we see a deterioration of the amygdala, which process emotion, and the prefrontal cortex, which helps regulate emotion. And together, what people often see in their loved ones with frontal love dementia is significant emotional and personality changes. For example, a woman who used to be really close and friendly and talkative with her children may become irritated and annoyed with them, may become angry with reasons nobody understands. This can be very difficult for family and loved ones to deal with obviously. When a person develops frontal lobe dementia, it tends to hit earlier that Alzheimerʼs does and it tends to progress more rapidly than Alzheimer disease. What do we do about dementias? How can we prevent them and how can we treat them? With prevention, itʼs difficult because dementia is correlated with senescence, the older we get, the more likely we are to develop dementia. So thereʼs a primary aging component that can influence it. Exercise has been shown to decrease the risk of certain kinds of dementias in particular, like multi-infarct or vascular dementia. But when it comes to Alzheimer disease, Iʼm afraid that the research is not pointing in any clear direction about how to prevent Alzheimer disease. There were some early studies that suggested that exercise and keeping the brain very active were correlated with a slightly lower risk, but recent research is casting that research in a more questionable light. We just donʼt know much right now about how to prevent dementia. For treatment, a critical factor is early diagnoses. Unfortunately, early diagnoses is really tricky. With dementia, an early sign could be whatʼs called mild cognitive impairment, which is a level of forgetness and memory trouble that is greater than the typical person of their age. But mild cognitive impairment leads to Alzheimer disease only about 50% of the time. Right now, although researchers are working very, very hard to find more answers, right now what we know for sure is that we can only tell if thereʼs been Alzheimer disease or other dementias for sure upon autopsy. We can slow down the progression of certain dementias though, and certain medications have been developed to do that. Those medications can add a number of years of cognitive capability to the personʼs life, sort of pushing off the development of Alzheimerʼs as long as possible. But drugs have not yet been identify to stop the progression or to prevent Alzheimerʼs from developing in the first place. On a more positive note and also keeping with the theme of unusual experiences, or atypical experiences in older adulthood, there are older adults who show growth, incredible growth in new areas as they age. Older adults in general can certainly learn new skills if theyʼre interested in doing so and if they choose to spend their time on them. For some, the experiences across the lifespan lead up to what Maslow wouldʼve referred to as self-actualization. This involves moving beyond the self to think of the self in context, the larger meaning of things. This can often result in a lot of new creative insights and spiritual meaning for the person, doesnʼt have to be religious necessarily, but spiritual, that thereʼs some kind of meaning to it. And philosophical ideas. Youʼll sometimes see in a self-actualized person, a really subtle sense of humor as well having to do with all of the experiences theyʼve learned from across the lifespan. As the story of Grandma Moses tells us, some older adults may find completely new talents that they didnʼt realize they had in older adulthood. For her, her artistic abilities began in her 80s. Some older adults spend a lot of time reflecting on their life and thinking about the events of their life in order to put it into a narrative, a story that makes sense. This can become a social process too, telling others, telling the grandkids, wanting to write your memoirs. The idea is that itʼs a sharing process while at the same it helps the older adult make sense of the things that have happened in their life. And finally we can talk about the concept of wisdom. In some ways we have stereotypes about this too, that older adults are wise, saying you wonʼt become wise until you are an older adult. Well, what is wisdom and when does it develop? Wisdom is considered to be, and this is a such vague definition but thatʼs the way it has to be, expertise in the fundamental, pragmatics of living life. The everyday practical, problem-solving, life lessons that weʼve learned. Wisdom is difficult to measure. Some scientists have been working very hard on it though, and they have found so far that wisdom is rare and itʼs rare at any age. Older adults are no more likely to be wise than adults of other ages, but the nice thing is a personʼs wisdom does not fade as we age. Itʼs one of those abilities and skills that if we have it, it tends to hold strong across those later years of our life. Chapter 15.1 – Late Adulthood: Psychosocial Development, Part 1 One thing that we can count on throughout the entire lifespan is change. Things will change. By the time we reach late adulthood weʼve experience many different changes. And a lot of losses and significant alterations to our physical body and our relationships and our roles in life. How do older adults manage all of these changes? Thatʼs the focus of this episode. Theories of Late Adulthood Genetics and environment. The individual and society. Weʼre very interested in lifespan development in trying to figure out the relationship between ourselves and the environments we live in and how they have an influence on one another. Two sets of theories provide us with this basic distinction once again. Self theories help us understand how people think about themselves in late adulthood and how for most of us we tend to just become more ourselves as time moves on. But there are contextual factors that have a major impact on the lifespan as well and stratification theories offer explanations of how societal pressures exert an influence on the individual across the lifespan and we see the accumulation of that at times in older adults. Letʼs start with self theories. This is a focus where we look at how older adults change or stay the same in the way that they think about themselves. If you imagine what it might be like, you in older adulthood will experience a lot of changes, a lot of changes in your physical body. There will be different roles that you are holding, maybe youʼll become a grandparent, maybe youʼll retire and not have that work role as you used to. And there are three basic ways we can understand how adults can cope with these changes. Erik Erikson proposed that the last stage of psychosocial development is integrity versus despair. Remember, Erikson always believed that there are two possible outcomes, kind of extremes. Integrity would be the positive outcome, despair would be the negative. And that each of us, if weʼre as healthy as can be, you know, we can develop towards the positive end but thereʼs always going to be a bit of element of that negative component as well. Let me make sense of that here with integrity versus despair. A sense of integrity is an understanding of the all of who the person has become and itʼs an understanding that a person has about himself or herself. Tying together all of the pieces of their life into a narrative, a story that makes sense for them. It isnʼt so much important that the story is completely accurate. Our memories are pretty fallible anyway, not even just when weʼre older adults, but when we think back in our lives, and when we put the events together into a story, even when weʼre younger, distortion and remembering things a certain way to suit ourselves is pretty common and that can absolutely happen in late adulthood. But accuracy isnʼt the important thing. The important thing is how the older adult understands his or her life. Understanding there are good times bad times but on the whole it was still a decent life or even a terrific life. That even though there were mistakes, that the mistakes were learning opportunities that a person adjusted to. But despair is a part of the acceptance f the end of life. Itʼs a reality that we will all die and itʼs also a reality that none of us knows how exactly that is going to happen. This generates plenty of anxiety even when younger people think about death. And as we age we get closer and closer to that experience. Itʼs normal to feel every once in a while a sense of despair about that. To feel sad about the time that has passed. But hopefully we are able to keep that in check with greater integrity on the whole; being able to focus on the present, using death as a motivator to make the most of the time thatʼs left. Continuity theory focuses on the way that we change and adapt in order to find new ways of expressing the same self. This is influence by temperament and personality. Across our lives we help build our own ecological niche; the way we like things to be, the kind of activities that fit our personality, and as we get older we may have to make some changes. A woman whoʼs been a librarian all of her life, perhaps, and enjoys interacting with children and reading to children may retire from her job as an elementary librarian but then spends some of her time volunteering at local libraries reading to children. Itʼs a change, but itʼs a way of expressing her same self in a different way that fits with her older adult life. Luckily, we have some benefits in handling changes as older adults. The positivity effect is a theory that shows how we selectively optimize the things that are good. We focus on the good more and more as we get older. This is referring to older adults on the whole. Of course, there are always exceptions. But the stereotype that many have that older adults are just grumpy people is not supported by the research. You read about a study by Sorkin and Rook, two people that I know actually, who looked at negative interactions that were occurring among older adults and other people and asked older adults what their goal was. So itʼs going to be a negative interaction, you know of those where weʼre not looking forward to it. Things are not going well, but we have some options for how to handle it. Do we blow up? Do we withdraw? Do we find a way to make the best of it? As we age, we tend to be focused on maintaining good will. Older adults are better at being able to focus on the positive aspects of a situation and not be so negatively affected as they might have been in younger years. In addition, and along with positively effect, we tend to move closer to our ideal self as we age. So if we like to think of ourselves as ideally even more patient and friendlier then we are, as we get to be older adults, we have a greater likelihood of actually moving closer to that ideal self. And what happens as a result is we tend to feel greater self acceptance and greater contentment. A second set of theories is referred to collectively as stratification theories, looking at the influence that society as a whole has on an individual. This is the idea that because of the way society is set up and the norms that we follow, we get placed in categories and different experiences are made available to people who are members of different categories. For example, in the United States, ethnic minorities are more likely to experience poverty in their lifespan than white Americans are, which white Americans are the majority of course. So these kinds of societal influences can trickle down to impact a lifespan, accumulative series of opportunities or lack of opportunities that contribute to the development of the individual and by the time we reach late adulthood, can accumulate and have very strong collective effect on the personʼs life course. This can help explain why older adults are so unique and such a diverse group because each has gone through a different series of specific pressures put on them because of our societal norms. For example, all of us across all ethnicities will be subject to age stratification. We tend to group people by age. We tend to spend time, mostly with people who are the same age as us, and this becomes particularly salient in the older adult years. Older adults are expected to be interacting with mostly other older adults. And what happens is that we miss out, all of us miss out because of this. We would benefit if the young and old had more opportunities and more encouragement to interact with one another. But as it stands, we have a socialization deficit because of age segregation. There are some theories related to this. One theory is disengagement theory. This is a theory suggesting that due to age segregation, older adults tend to stay isolated with other older adults and even more so begin to withdraw more into themselves as individuals. Disengagement theory suggests that society and the individual mutually prepare for the exit of the individual from life, withdrawing from each other. So we expect other adults to retire, we expect them to not be working full time, we expect them to be taking it easy and then at the same time older adults maybe choosing to not go out as much, choosing to engage in fewer activities. But this was a theory that mightʼve fit older adults better in the past and also may have been more negative than was warranted even then. Activities theory suggest this is the case. Activity theory is based on research that shows disengagement is not what most older adults like to make. If it occurs, itʼs not because older adults necessarily want it that way. Activity theory shows us that adults that stay active, even if theyʼre taking regular walks or just staying involved in community activity groups, being involved in activities correlates with a higher quality of life in late adulthood. Of course, itʼs important for older adults to be aware of any limitations that they may have so theyʼre not pushing themselves too hard in the midst of physical problems or other challenges they face. But the idea that we turn within ourselves and stay home and just slide on out of life does not match with the data and does not match with the experience with most older adults. Ethnicity is another stratifying feature of the lifespan. As youʼve heard many times throughout the semester, ethnicity is related to poverty, educational opportunity and achievement, employment and health outcomes in some cases. These limitations can have a significant impact on the shaping of the life course. And cultural differences that are embedded within different ethnicities can make a big difference as well; especially when weʼre thinking about the experience of older generations who have emigrated here, whose children and grandchildren who have become very accustomed to the American way of life. This can present a challenge as these older adults are still operating more from the culture of their origin and perhaps may want to live with their younger children, may want to have more family contact but find themselves in a nation thatʼs not as accommodating to multiple generation families. Where work life, where home designs do not accommodate multiple generation living as they would in other nations. Gender stratifies us as well. Men and women tend to take on different roles across the lifespan and these can accumulate and impact older adulthood. Women tend to take care of the home and men tend to take care more of the world of work, especially in the generations of individuals who would now be older adults. For example, if someone is sick, if a spouse is sick, the man is more likely to respond by working more hours whereas the woman is more likely to respond by quitting her job or reducing her hours to take care of her spouse, so woman tend to emphasize care. And what can happen over a lifetime is that kind of emphasis on caring can lead to poverty because a woman may not take advantage of the occupational opportunities that come her way because sheʼs more concern about taking care of those who need her help in her family and these kind of decisions can lead to social isolation as women are more prone to stay in the home and less likely to feel that itʼs acceptable to go outside of the home for work or for activities or to focus on things besides the relationship and for the person for whom they are caring. There are exceptions to these rules. In some cases, having been a member of a group thatʼs discriminated against in one way or another, whether is minority status or whether itʼs gender, or perhaps even economic status, some of us are able to develop coping skills and these coping skills that weʼve had to exercise across the lifespan can make it a little less of a challenge to cope with the stress of dealing with age changes. Furthermore, itʼs true of both women and of people of ethnic minority that they tend to have stronger quality relationships with others of the same group. For example, black women tend to have stronger, higher quality relationships with other black women, for example, and these stronger connections can help as well when coping with aging. And women across different ethnicities, women tend to have stronger family ties than men do, and this may be an advantage for women when coping with the losses of aging. Activities in Late Adulthood Where are late adults spending their time? What are they doing? Theyʼre doing a lot of different things. Some of them are still working, and some of them, many of them, are still working for pay. There are practical reasons for this. Some just plain need the money. And in that kind of situation, itʼs incredibly helpful to have a way to keep earning money. But others continue to work because they enjoy it or because they feel valued. Itʼs a place where they have social interaction. And it can increase their sense of independence. Retirement could be a good idea or it might not be a good idea. It really depends on the circumstances leading to it. If a person is relatively healthy before retirement, if theyʼre leaving their job not because they have to due to health reasons but just because they want to, they tend to enjoy it more. And in this case, retirement is not associated with any kind of downturn in their physical health. The impact of retirement also depends on how well prepared the older adults was before retiring. Had they thought through the changes they would need to make, especially the financial aspect of retirement. If so, retirement tends to be experienced as a positive. You donʼt have to be working for pay in order to make a contribution to society though. Volunteering is another route. It has the tendency to bolster health and well-being among older adults, especially if itʼs done in moderation and especially if the volunteer role is one where the person feels needed and respected. But only about 25% of older adults volunteer. Why? Itʼs hard to tell but one possibility is that older adults maybe engaged in more informal volunteering, kind of activities that involve helping a neighbor or helping out a loved one who needs some assistance. These activities wouldnʼt fall under the category of official volunteering, but they still involve the same kind of helpful behavior thatʼs directed toward others without any kind of financial compensation. When it comes to home life, older adults tend to enjoy their homes and pay more attention to their homes and like to spend more time making their homes the way that they like them to be. In fact, older adults, most of the time, would prefer to grow old in the same place in which they have developed. They want to stay in the same area; they liked to be in the same neighborhood even, or if they can swing it, even in the same house. The point is that most older adults would prefer to stay where they have been instead of dealing with the adjustments that would be required if they had to move somewhere else at that age. In some cases, interestingly, a group of people that moved into a community as young adults stay there and didnʼt leave. Now that theyʼre older adults, theyʼve become whatʼs called a naturally occurring retirement community. It isnʼt an official community, but itʼs a community thatʼs sort of developed over time because of individuals who wanted to age in place. They help each other as they age. If one of them becomes a widow or widower, they tend to prefer to live alone because they know within that community they still have support. Older adults are sometimes students at school. Continuing education is whenever older adults are attending school because they just are interested in learning. There may not be a goal of a degree. There may not be a goal of getting a certain kind of job later, but the interest is in learning for the sake of learning. I have certainly had older adults in some of my classes. One of the really great things about older adult students is their motivation. This is a fun and interesting for them. Theyʼre excited to be there and excited to learn about the things that the teachers are excited to teach about. But the fast pace nature of college and the emphasis on technology may be a deterrent for some older adults. They have the option of taking elderhostel classes if those types of classes seem to fit better. Elderhostel classes are designed in particular to older adults. Activities and topics that might be of great interest to greater adults are the focus of elderhostel adults, and other students are other older adults. Many older adults maintain a strong sense of faith in their particular religion or spiritual beliefs. Religious involvement for religious adults, especially in terms of their personal beliefs, tends to increase across time. And it may or may not correspond with an actual increase in church involvement or church attendance, but that sense of faith in older adulthood is correlated with health and psychological well being. Perhaps it helps people cope with the reality of their death. In some cases, especially in the black faith community, thereʼs so much involvement in the neighborhood or the community at large thatʼs connected to churches of various kinds; so many activities, so many opportunities for volunteering and a very strong sense of continuity and meaning. Especially for many black American women, their faith community is a central component of their experiences in older adulthood. And finally we consider politics. Political activism – older people are more politically involved on the whole than younger people are. Youʼre probably not going to see many of them waving signs at rallies but a lot more of them are at home writing letters to their representatives and staying on top of the news so that they understand current events. The AARP, the association that represents people who are older adults, is the largest interest group involved in politics. And the interests that older adults have in politics goes beyond just those policies that directly impact them. I mean, of course, older adults are particularly concerned about healthcare, Medicaid, and social security, but the research tells us that older adults are also interested in the development of children, in funding education. With the pace that is normally needed for political change to actually occur, when older adults are concern about these issues, itʼs clear that they are thinking about the future beyond when they will still be here on Earth, making contributions to future generations. Chapter 15.2 – Late Adulthood: Psychosocial Development, Part II This is the second episode about psychosocial development in late adulthood. In this episode we talk about the role of friends and relatives in the life of older adults as well as the circumstances that are particularly important to consider when older adults become frail. Friends and Relatives Most people end up getting married. Those who are lucky enough that theyʼre still married in their older adulthood and happy in that marriage tend to experience all of benefits from the long term relationship. Long-term partnerships are correlated with health, with wealth, and with psychological well-being. When two people have spent this much time together and have had so many shared experiences and memories, theyʼve also had a lot of opportunities to adjust to each other. Typically, long-term partnerships are characterized by interdependence, where each person needs the other, and mutual respect, both members of the couple admire each other. And when they age, long-term partners tend to fill in for each otherʼs shortcomings or weaknesses or physical limitations. When people retire, it can create an adjustment period in long-term partnerships because now, at least one of the members of the couple, if not both, will be home and spending more time with each other. In fact, the research does suggest that itʼs best for long-term partnerships when both people retire at about the same time. Otherwise, it tends to be a challenge to the relationship if one person is working for pay and if that person is also making most of the decisions around the house. I think itʼs interesting because this is difficult for men to handle, but itʼs also difficult for women to handle whenever their husbands are working and they are not and their husbands are making most decisions. So it appears when it comes to older adulthood and long-term partnership, it doesnʼt feel right to have that kind of imbalance of power. Perhaps it makes it more difficult to maintain the interdependence and mutual respect. When a spouse or a partner, a long-term partner dies, obviously this is a major adjustment. And itʼs an adjustment that women face more often than men. Women tend to outlive men. Women also tend to marry men who are at least a little bit older, so for these reasons, there are far more widows than there are widowers. But after an adjustment period, women tend to function pretty well and most of them do not want to get married again. They usually have strong social ties with other women and with their family, but for men, for widowers, itʼs usually harder. Thereʼs less support provided to men who have lost their spouses. We donʼt reach out as much to male family members as we do to female family members. Widowers are far more interested in getting married than widows usually are, and the thing about this is the ratio of available single women is working very much in widowerʼs favor, so those who would very much like to get married are able to find another partner. We are living longer and weʼre having smaller families. The beanpole family is a common result then. This is a family where there are multiple generations that are alive, but not many people in each generation. So thereʼs kind of a tall, skinny family tree, family beanpole. Adults feel a responsibility to help take care of their aging parents and this doesnʼt necessarily mean they will be the person providing the care, but they feel responsible for helping the care be available, for arranging the care for whoever it ends up being the care. Itʼs challenging because help that they provide to their aging parents, while it might be very much needed, it also may very much be resented by the older adults. Especially in the United States, we really donʼt like feeling dependent, we really enjoy feeling independent. And we see a shift as we get older in our expectations for how much support we think older adults should be given versus how much support we think we ourselves need once we become older adults. As we age, our tendency is to shift the perception so that we feel we donʼt need as much support as we might have anticipated an older adult would need when we were younger. And perhaps this is because as we get older and where we are interpreting our situation, itʼs hard to understand and appreciate and accept the level of help we may need. So we may have a generational shift here or sort of a generational conflict where the midlife adult children may feel like they should be doing all kinds of things for their older adult aging parents, but those elderly parents may have shifted their perception to feeling like they donʼt need that much support. So when the midlife adult child provide support, the elderly parent may resent it or maybe bothersome to them in some way. They may feel like they are viewed as weaker than they really are. When relationships between adult children and their elderly parents are particularly supportive and emotionally close, thatʼs when the tension related to this care giving tends to be the greatest. Friends are important throughout the lifespan and that continues in older adulthood as well. This is especially true for older adults who donʼt have spouses, perhaps they never did have spouses or perhaps they are a widower or widow, and this is especially true for those who chose or those who arenʼt able to have children. Friends can be a very important source of support and everyone needs at least one good one. At least one good friend. Especially in older adulthood, the research shows us that elderly adults donʼt have to have lots and lots of friends, as long as the friends that they have are high quality relationships. Quality matters much more than quantity. The Frail Elderly Frail elderly are those individuals who have difficulty functioning because they have severe illnesses, or because they have a physical disability, or because they have significant cognitive impairment of some kind. Usually, the frail elderly are the oldest old. This is due in part to the compression of morbidity. There was greater frailty earlier lifespan in past decades, but now that weʼre living longer and living healthier lives for a longer period of time, our period of morbidity, of significant disease and disability before we die tends to be much shorter now than it used to be. Frail adults have difficulties with activities of daily life. Activities of daily life are self care activities. The kinds of things that we need to do on a daily basis just to be healthy, functioning human beings. Plain old activities of daily life, which are called ADLs, are very basic, straight forward tasks like dressing yourself and being able to eat on your own and take a bath. Instrumental activities of daily life, which would be IADLs, are tasks that are also something that we do regularly but that require more mental effort, more cognitive skill. These would be things like taking the proper dosage of medication at the right time, being able to follow a recipe and bake something. Older adults tend to begin having trouble with IADLs before they have trouble with the ADLs. Family members are often called upon to help step in with these self care activities. Family care for the frail elderly is usually provided for by a spouse. Itʼs particularly difficult if the person needing care has Alzheimerʼs disease. The cognitive impairment of Alzheimerʼs disease can result in pretty significant and scary changes in the elderly personʼs personality and temperament and interactions. A husband might be concerned that his wife with Alzheimerʼs may wake up in the middle of the night and walk out the door into the neighborhood. When caring for a family member, in general, sometimes itʼs a sibling thatʼs taking care of the elder person, and there can be some conflict because of this among siblings. The siblings who are providing the care may feel jealous that the other siblings are not. The person whoʼs not providing care may have a sense of relief, and then immediately, usually a sense of guilt about it as well. The relationship between the older adult and the child whoʼs taking care of him or her is also to be strained because they have to make a lot of agreements and follow a lot of plans based on the health of the elder person, so there can be disagreement about the older personʼs schedule, about when they should be eating, about how often they need a bath. And lack of access to public services can put a lot of strain on the caregiver because it puts the entire responsibility on that person. Nobody functions wells on the job if theyʼre burned out and overwhelmed, and then imagine on top of that, the person youʼre caring for, who you very much care for deeply and very concerned about. Itʼs important that the strain on the caregiver be recognized, and if possible that the caregiver is given breaks, periods of times or a few days when medical professionals can check in to see if everything is okay. And this can allow the caregiver to have some time off and come back feeling more relaxed and refreshed. In some cases, if the pressure is so significant or if there are other problems with either the caregiver or older adult, elder abuse can occur. This is when the older adult in need of care is treated badly. It could be emotional maltreatment. It can be neglect. It could be financial mistreatment. And mistreatment of older adults, elder abuse in particular, is most likely to occur when there is a combination of factors that are having an influence, like if the caregiver is unstable in some way, letʼs say, the caregiver is addicted to some substance, and if the care is occurring outside of the view of others, in sort of an isolated area or place where others donʼt see very often. And if the older adult has some kind of serious memory loss or cognitive impairment. When those three characteristics are all occurring, thatʼs when elder abuse is most likely to happen. If family care is not available, or if the older adult does not want care, or if the problems are significant enough that more assistance is needed, frail elderly may spend time in long-term care. This is what we would call a nursing home. And most of us have negative ideas about what a nursing home is like. There is a wide range of quality when it comes to nursing homes and quality of care matters greatly. Unfortunately, it usually takes money to buy high quality care. These days, there are fewer older adults in nursing homes though, and those who are in nursing homes are more frail. Again, we can see the compression of morbidity happening here - that we donʼt need as lengthy of period of care, but when we do need care, itʼs closer to the end of our lives. Now remember, thatʼs long-term care. Lots of older adults will need some kind of short-term care after theyʼve had a surgery or after theyʼve recovered from an illness, but those are typically short stays, you know, a month or maybe more, but itʼs not intended to be a permanent placement. Assisted living is another option that a lot of older adults like because itʼs a combination of independent living where the individual usually gets to have their own room. They can decorate it in a way that they like; maybe they can even have a pet, in some cases. And they have some control. There are communal events. There might be one meal a day thatʼs communal or perhaps more, but the idea is that they have the flexibility of being independent while at the same time having access to some of the medical supervision that they would get at a nursing home, like doctorʼs that are available when necessary and the ability to get emergency intervention if thereʼs some kind of urgent medical problem that arises. Living in such a place also provides an opportunity to interact with others and that can be very important. Yes, we would all like to be able to stay independent, but at the same time, we still benefit from having quality relationships with others. And assisted living can sometimes provide that kind of scenario. Epilogue – Death and Dying Some might think of it as depressing, but we have to end our course talking about a subject that most people are uncomfortable thinking about – death. But I donʼt really see it that way. Instead, letʼs look at it as an opportunity to learn about an event that is unfortunately inevitable. Weʼre never going to feel completely at ease with the idea of dying, but if we learn more about it, we can better prepare ourselves for coping of the death of loved ones and ourselves. This is the primary goal of thanatology, the study of the emotional and the social aspects of dying. Death and Hope What does death mean? The meanings of death depend on many things including how old we are, whether itʼs us dying or someone we love whose death we are coping with, and also our belief system. Letʼs talk about age first. People are often concerned about how to talk about death to children. When children are dealing with their own death, their biggest fear is a fear of abandonment, concerned that others are going to leave them. And so itʼs actually advisable in such cases that parents and caregivers of terminally ill young children or fatally wounded young children to stay with them at every moment if they can, trading off, of course, for someone to get some rest, but the fear of abandonment is pretty common in kids. And when itʼs someone elseʼs death that a child is learning to cope with, there are a lot of different responses you can see in children. Honesty, typically, is the best policy. Although children often donʼt feel the need to understand the details until they get older in the concrete operational stage, you know grade school or so. Interestingly though, children of different ages have a different understanding of what death means, that what is possible after the death of an individual, for example, they may think that a dead person can still think things and can still have emotions. In adolescence and emerging adulthood, in regards to oneʼs own death, the risk is that thereʼs actually a low fear of death during this phase of the lifespan coupled with an interest with taking risks. So this can result, especially in some cases, in adolescents and emerging adults behaving in dangerous ways without grasping the degree of risk that they are taking with their life and in some cases they may even romanticize death. Moving into adulthood, dealing with our own impending death, if itʼs happening in adulthood, obviously thatʼs off time, right? We may have spouses, children, responsibilities, and the concerns usually center around whoʼs going to take care of these responsibilities when I am gone. In coping with the death of others, adults tend to show different kinds of reactions based upon the age of the deceased person. Deaths that are so-called off-time, you know when we say “Oh, he was in his prime,” “He shouldnʼt have died; he was only 50 years old,” - those are deaths that are typically harder for adults to cope with. In late adulthood, anxiety about our own death decreases. We become more accepting of death. Older adults are much more likely to face the kinds of difficult tasks that they wanted to get done before they die, that all of us really should be thinking about but most of us avoid when weʼre younger because we donʼt like to think about death. Things like making sure we have a will and that itʼs set up properly, trying to repair any relationships that have been strained, these kinds of things. Older adults also show a shift in their priorities. They prioritized time spent with family members, knowing that they have limited time left. Regardless of age, spiritual beliefs have an influence on the way that we think about death. If we think death might happen soon, either itʼs because we have a terminal illness or weʼre in a situation that is threatening our lives, like living in an extremely violent area, then we tend to have stronger religious and spiritual beliefs. The specifics of how we cope with death, though, vary greatly. There are many different way s that certain cultures and certain religions choose to cope with the death of loved ones, different rituals, different rights, different customs…the connection between anticipating your own death and becoming more spiritual or religious is also seen in people who thought they were dying but didnʼt actually die –near-death experiences. Iʼm sure youʼve heard of near-death experiences where people feel like theyʼve sort of been raised out of their own body and they were floating toward a light and for whatever reason, it felt wonderful and terrific but then they came back and recovered. And for many people whoʼve had this experience, it has a dramatic impact on the way they view the world. It often affirms their spiritual beliefs. For some people, it leads to the development of spiritual beliefs that werenʼt there before. Many people feel the need to make sense, to make meaning, out of their lifeʼs experiences. Dying and acceptance We would all prefer to experience whatʼs called a good death, a fast death preferably at the end of a long and happy life, thatʼs peaceful and painless and happens in the presence of loved ones in a comfortable setting, preferably not a hospital, right? Itʼs ironic that advances in medical science have increased the likelihood of a good death. At the same time as they have increased the likelihood of a bad death, a death that takes a long time to happen, where we die alone, where weʼre in pain. The medical advances that allow us to live longer and healthier lives can also lead to measures trying to prolong the length of life, sometimes at the expense of the quality of life. Overall, weʼre in much better shape than we used to be though when it comes to dealing with death. Itʼs amazing to me to think that at one point in time not so long ago, it was not uncommon to keep the information that a person is dying secret from the person who is dying. Doctors and family members might not tell their loved one how serious and dire the situation is, that theyʼre likely to die soon because they were afraid of making the situation worse, they were afraid of making the patient upset, or they just didnʼt want to talk about and just didnʼt want to admit that it was happening. It was a remarkable advance when a woman named Elisabeth Kubler Ross actually dared to interview people who were dying, to find out what their experience was like. No one had ever been so open and honest and respectful about understanding the dying process. And the research that Kubler Ross conducted has improved the experiences of countless people when theyʼre going through the process of dying. Kubler Ross suggested that we go through stages of dying, where we experience denial at first, then anger, bargaining, depression and finally acceptance. Today, the problem we might have with these stages of dying is that people think that theyʼre meant to be followed in a specific order, and Kubler Ross thought that might be the case as well, but research has shown us since then that we do not go through predictable stages. The important thing to know is that there are a variety of reactions that a dying person might have and that the personʼs emotions are likely to change. We just donʼt know which direction theyʼll change in, and we donʼt know which kind of emotion is going to come next. We can do harm in fact, if we think that a dying person should be following a certain series of stages when they are in fact not doing so. Loved ones might expect itʼs about time for the dying person to move into the acceptance stage when the dying person may be experiencing a phase of anger. We do more harm than good when we try to correct the dying person and suggest that they should be feeling something different. The dying person will respond in his or her own, unique way. Thanks to Kubler Ross though for opening the topic so we can talk about it honestly. We can also help the dying person by providing hospice care. Hospice care is intended to provide a smoother transition to death for the dying person. Allowing the patient to make some decisions and to help direct the process like making decisions about when they want pain medication and when they donʼt, teaching friends and family how they can assist and help keep the dying person comfortable and also how they can prepare for the impending death of their loved one and cope with their grief after the death. Rates of hospice care in the United States have increased greatly in recent years. The development of the subspecialty of palliative care has also been a help. This is a medical subspecialty focused on making a dying person as comfortable as possible. This is focusing on the alleviation of pain, the alleviation of discomfort. Palliative care is not about trying to cure any illness or to fix anything thatʼs broken, itʼs about being able to provide the person with as pain-free of an experience as possible. Palliative care can happen in a hospice; it can also happen at a hospital as well. Some of the painkillers that are given to people who are near the end of life have whatʼs called a double effect. These are painkillers that not only alleviate pain or reduce pain but they also slow down respiration, which tends to bring about death a little bit sooner. This is acceptable from a legal perspective and people in general tend not to have too much trouble with this idea that the pain medication may help hasten the dying process. What are a lot more controversial, though, would be the other methods that might be used to help hasten death in a more direct way - euthanasia, for example. This is the part where itʼs ironic that medical advances have helped us avoid diseases or get better faster, and at the same time medical advances have helped us prolong life to an extent where the quality of life can sometimes become a concern. What kind of options should we have? How much choice should we be given when weʼre near the end of our own lives? This is all complicated, of course, by the reality that sometimes people do not have the cognitive clarity or the ability to communicate what they really want at the end of their lives. Theoretically, the least controversial of these topics is passive euthanasia. I say theoretically because the reality of passive euthanasia is a lot more complicated, but passive euthanasia is when natural death is not prevented. For example, if thereʼs a “do not resuscitate” note in the personʼs file where the person in the past has requested that measures like restarting the heart again are not to be done, then the person will die a natural death. This is legal and itʼs actually quite common. The complicated part is that in reality, there can be gray areas. There can be ambiguities. There can be differences in the perspective of doctors and family members or among the family members themselves, even with something like passive euthanasia. Active euthanasia is far more controversial. This is when a medical professional provides a drug that makes death happen faster. This is illegal in the United States. People have a harder time accepting the idea of a medical professional giving someone a drug that will end their life than they have with the idea of something like double effect where painkillers known to slow respiration are chosen to be used so that it will help death occur faster. Position-assisted suicide occurs at the hands of the dying individual, him or herself, but it requires the authorization of a physician who is willing to prescribe medication that will end the personʼs life and the person takes that medication at home and is able to have whatʼs called a death with dignity, if they choose. This is legal only in Oregon in the United States and there are strict guidelines that must be followed. You have to request a couple of times, two times orally, one time in writing…there has to be a certain period of days before the medication will be given to the person. This is all to make really sure that people arenʼt committing hasty decisions, that a decision isnʼt driven by depression or something, or an impulsive idea, so care is taken; as much care as possible is taken to make sure that this option is not abused or used improperly. However, it is very controversial and is legal only in Oregon here in the United States so obviously there are lots of concerns that people have about this being available to people with terminal illnesses. None of us want to create scenario for our loved ones where they have to make difficult decisions for us about our end of life care. Advanced directives are a way to try to make things easier on your loved ones. These are instructions that you provide before you become ill, that lay out the kinds of things that you are comfortable having done to you, what types of life extending options, if any, youʼd like to be given. But again these are clear in theory but then complicated, often times, in applying to real life cases. A living will, for example, is a will that the person writes up ahead of time that will be used if he or she cannot communicate later when they are ill and near death. But the terms can be ambiguous. Perhaps, in the living will it says that the patient does not want any extraordinary measures to be undertaken. Thatʼs a very vague word, extraordinary measures, what does that really mean? Clearly, there is plenty of room for differences of opinion which can complicate those decisions the moments where those decisions need to be made. A health care proxy may have been identified by the individual whoʼs dying. This is a person that you would identify ahead of time to make medical decisions if you are unable to do so, but again, thereʼs the issue of interpretation. And now it can be a lot of pressure on that health care proxy to feel like the one who has to make that interpretation and make that decision. Bereavement When it comes to bereavement, in other words, the feelings of loss that we have after a loved one dies, there is no right way and no wrong way to experience it. Grief is a very unique experience that happens soon after the death for most people. Where a person feels deep sorrow and anguish and overwhelming, intense and often times irrational series of emotions and thoughts are going through the personʼs mind. We cope by going through a process of mourning. These are the ceremonies or the traditions or the rituals influenced by culture or by religion or by the community that help us manage our feelings and express our feelings of loss for a loved one. Mourning is often public, at least, somewhat public, whether itʼs attending a wake, a funeral, sending condolence cards…itʼs a public recognition that those dealing with the death of a loved one will be particularly vulnerable at this time and will need some kind of help with the healing process. Why do people have this impulse to take food to someone whoʼs recently lost a loved one? Weʼre concerned that in their grief they might not be taking care of themselves very well. We want to help them pick up the pieces and be able to provide some support to get them through this very difficult time. The process of experiencing grief maybe complicated. For example, absent grief occurs when a personʼs approach to coping is to isolate themselves, avoiding situations where their grief would be public, not wanting to talk about it with anyone, not wanting to go there. Unfortunately, this level of repression can lead to physical illness or to depression, and itʼs most common among people who arenʼt well connected within their communities and donʼt have strong relationships. Please donʼt misunderstand. Absent grief doesnʼt mean that thereʼs a problem that the person needs to be loudly expressing and you know, crying and doing the socially acceptable things. Thatʼs not the point. The point is that the person is withdrawing, isolating and stuffing down any kind of reaction. Some people donʼt have a strong outward expression of grief directly after a loved one has died. Thatʼs not necessarily absent grief. But if they are holing themselves up and not wanting to participate or acknowledge or talk about any of it, thatʼs when itʼs more of a concern. Disenfranchise grief occurs whenever people who are very much grieving and would like to participate in the mourning process are cut off from it for whatever reason, perhaps because of the customs or the family norms that are involved. For example, homosexual partners may not be included in the decision making or in the planning for the events that would honor the person that has died; perhaps it was their boyfriend or girlfriend. They may be neglected, thatʼs an experience of disenfranchised grief. Or perhaps the individual who passed away was very close friends but very distant from family. The friends may have a better idea of what that deceased person might have wanted for a ceremony. The friends might want to participate but the family may prevent them from doing so. Incomplete grief is another form of complicated grief where other events that occur right around the same time or directly after the personʼs death get in the way of grieving. Like a crime investigation or autopsies. Grief may be incomplete for some if a body has never been recovered, and if theyʼve not been able to carry through with their traditions of mourning because of it. The one thing that we can say for sure about bereavement is that no two people are going to go through it in the exactly the same way. The circumstances will be different. The emotions will be different. The reactions will be different. Some of the assumptions that were so strongly held in the past have recently been challenged by the research. For example, after a certain period of time, we should be able to move on and break that attachment bond with our deceased loved one. This was a well intentioned idea, hoping to prevent people from escalating into extreme, prolong grief, but the research tells us now that thereʼs no time table. That when you let people grieve in the way that seems to come naturally to them, most people do not escalate into extreme or complicated grief. In fact, we may actually do more harm by approaching a bereavement situation with a set idea of how things should go. You know, it really does come back to one of the themes of this course: there are so many things that we all will experience, and death is one of them. In that way, weʼre all the same. But we are, at the very same time, completely unique.
