Chapter 11 The Developing Person Developmental Psychology “Womb to Tomb” Psychology The Life Span Developmental Psychology • Developmental Psychology: – A branch of psychology that studies physical, cognitive, and social change throughout the life span • Research focuses around three major issues: 1. Nature vs. Nurture 2. Continuity vs. Stages 3. Stability vs. Change Developmental Research Methods • Cross-sectional study: a study in which people of different ages are compared with one another • Longitudinal study: research in which the same people are restudied and retested over a long period The Major Stages of Life • • • • • • • • • • • • Conception Pre-natal: conception- 36/40 weeks Infancy 0-2 Childhood pre-school 2-5 school child 5-12 Adolescence 13-17/19 Adult young 20-30’s middle 40-50’s old 60-0ver Death Basic Processes of Development Basic Processes of Development • Maturation – in the study of development, maturation is the most important factor to consider – maturation is a progressive unfolding by “schedule” – you will begin to walk at a certain age range, begin to talk at another age range, etc. – biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience Infant Gross Motor Milestones Motor Development: progression of muscular coordination required for physical activities Physical Skill Set: cephalocaudal trend: head-to-foot direction of motor development Proximodistal trend: center-outward direction of motor development -Lift head: 1 month -Hold head up when in sitting position: 4 months -Control head & neck: 6 months -Roll over: 6 months -Sit up unsupported: slightly after 6 mths -Crawl: by one year old -Walk: 90% by 15 mths Developmental norms: typical (median) age at which individuals display various behaviors and abilities THE STAGES OF DEVELOPMENT Prenatal Period and the Newborn Zygote (Stage 1) the fertilized egg (one celled organism- sperm/egg) enters a 2 week period of rapid cell division less than half survive pass 2 weeks develops into an embryo Embryo (Stage 2) Embryonic process begins with the forming of the placenta the developing human organism from 2 weeks through 2nd month Fetus (Stage 3) the developing human organism from 2 months (9 weeks) after conception to birth Prenatal Development and the Newborn Teratogens agents, such as chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause harm EX.

(Full-term is 37 to 42 weeks Early experience and critical periods CRITICAL PERIOD: A period in a person’s development in which a given event will have it’s greatest impact on the individual Shortly after birth: an optimal period when an organism;s exposure to certain stimuli or experiences produces proper development. WHICH IS DIFFERENT FROM THE… Social clock: The culturally preferred timing of social events such as marriage, parenthood, and retirement. Early Experience/Critical Periods • Imprinting (Konrad Lorenz): a form of early learning that occurs in some animals during a critical period in their development and involves the formation of attachment • Early social deprivation: Harry Harlow Imprinting: Konrad Lorenz • demonstrated how incubator-hatched geese would imprint on the first suitable moving stimulus they saw within what he called a "critical period" of about 36 hours shortly after hatching. The Harlow Monkey Experiment • WWII, Harlow served overseas • Noticed orphanages filled with 1,000’s babies • Babies fed, clothed, changed • Babies not held by nurses • “Rocking baby syndrome” The Nature of Love • "Mother Love" and its consequences for social, sexual, and cognitive development. • infant attachment and social bonding. • Monkey love • Harry Harlow's classic primate experiments suggest that to understand the human heart you must be willing to break it • "In Harlow's initial experiments infant monkeys were separated from their mothers at six to twelve hours after birth and were raised instead with substitute or 'surrogate' mothers • 'surrogate' mothers made either of heavy wire or of wood covered with soft terry cloth. • Harlow discovered that baby monkeys deprived of their mothers (left) would transfer their affections to a cloth surrogate. Social Development Harlow’s Surrogate Mother Experiments Monkeys preferred contact with the comfortable cloth mother (body contact), even while feeding from the nourishing wire mother • as soon as the infants finished nursing, they abandoned the wire monkey and clutched the cloth one. • When the cloth model had the bottle, they didn't go to the wire model at all • One control group of neonatal monkeys was raised on a single wire mother, and a second control group was raised on a single cloth mother. • no differences between two groups in amount of milk ingested or in weight gain. • difference between the two groups lay in the composition of the feces, the softer stools of the wire-mother infants suggesting psychosomatic involvement. • The wire mother biologically adequate but psychologically inept. http://www.youtube.com/watch?v=E2M6XBJEEFQ&feature=related Effects of the “Wire Mom” • "...the actions of surrogate-raised monkeys became bizarre later in life. They engaged in stereotyped behavior patterns such as clutching themselves and rocking constantly back and forth; they exhibited excessive and misdirected aggression..." • Harlow found that young monkeys reared with live mothers and young peers easily learned to play and socialize with other young monkeys. • Those with cloth mothers were slower, but seemed to catch up socially by about a year. • Babies raised with real mothers but no playmates were often fearful or inappropriately aggressive. • Baby monkeys without playmates or real mothers became socially incompetent, and when older, were often unsuccessful at mating. • Those unsocial females that did have babies were neglectful of them. http://www.youtube.com/watch?v=uRI8VKApgsU&feature=related 7 min 30 sec- til end Natural Curiosity http://www.youtube.com/watch?v=kRCPRz4Zq2o&feature=related Research Results Attachment Theory Attachment: powerful survival impulse that keeps infants close to their caregivers • 2 major developers of attachment theory: Bowlby: • – attachments between humans are adaptive over the course of human evolution • Infants are biologically programmed to emit behavior that triggers a protective response from adult females. • – bond formed between the infant & primary caregiver is a general prototype for all subsequent love relationships • – parents provide a “secure base” from which child can adventure into the world & return knowing they will get safety & comfort Attachment Theory Ainsworth: • – pioneered assessment & comprehension of individual differences in attachment • The Strange Situation Experiment – Infants are exposed to a series of eight separation and reunion episodes to assess the quality of their attachment – Has to do with separation anxiety: emotional distress seen in many infants when they are separated from people with whom they have formed an attachment (peaks 14-18 mths) AINSWORTH'S STUDY OF THE TYPES OF ATTACHMENT • Aims: To do a study which investigated the security of a child's attachment with their caregivers. The study provided a number of episodes that provide various measures of the attachment relationship. • Procedures: Children aged 12 - 18 months and their mothers were the participants. Observation was viewed through a one-way mirror. There were several episodes in the study, that included the following: • - Caregiver and infant enter the room. - Child plays with the toys while the mother is present. - A stranger enters the room and the caregiver leaves. - The stranger tries to comfort the child. - The caregiver returns and the stranger leaves. - The caregiver comforts the child and then leaves for a second time. - The child is left alone for 3 minutes. - The stranger enters and interacts with the child. - The caregiver enters, picks up the child and the stranger leaves. • https://www.youtube.com/watch?v=i5MudJ7yxkE&safe=active • Findings: Three catagories of attachment were identified: • SECURE - The baby considers the mother to be a safe base to explore from. The child showed distress when the mother left the room and seeked interaction with her as soon as she returned. 70% of the infants fell into this catagory. Greater curiosity, better peer relations, more self-reliant….NOT higher morality • AVOIDANT (insecure)- The child paid little attention to the mother and was not distressed when she left the room. the child was easily comforted by the stranger. The mother was ignored upon her return by the child. 15% of the infants fell into this category. • RESISTANT (insecure)- The child showed simultaneous seeking and resistance to the mother. The child was very distressed when it was separated from the mother and was difficult to comfort upon her return. 15% of the infants fell into this category. • Disorganized/Disoriented Attachment: – Upset – May happily greet but then turn away or approach without looking Social Development: Child-Rearing Practices Authoritarian parents impose rules and expect obedience but over little parental responsiveness “Don’t interrupt.” “Why? Because I said so.” Permissive submit to children’s desires, make few demands, use little punishment Authoritative both demanding and responsive set rules, but explain reasons and encourage open discussion Results: highest self-esteem, self-reliance, & social competence…b/c granted more control Uninvolved cares for basic needs but shows little communication, few demands, & low responsiveness Results in little self-control; low self-esteem & competency Early Experience/Critical Periods • The “Battered-Child Syndrome” – identified in the early 1960s – child abuse can pass from one generation to the next – approximately 15% of child abusers do not change their ways even with social service and court intervention – approximately 2,000 children killed annually as a result of child abuse Child Abuse • Types: physical, sexual, emotional, neglect • Another type of abuse is child exploitation • Over 3 million (3,195,000) children were reported for child abuse and neglect to child protective service (CPS) agencies in the United States, in 1997 • reports currently suggest about 47 out of every 1000 children are reported as victims of child maltreatment. Overall, child abuse reporting levels have increased 41% Sexual Abuse • • • • • • • • • • • • any sexual act between an adult and a child. This includes: fondling, touching, or kissing a child's genitals making the child fondle the adult's genitals penetration, intercourse, incest, rape, oral sex or sodomy exposing the child to adult sexuality in other forms (showing sex organs to a child, forced observation of sexual acts, showing pornographic material, telling "dirty" stories, group sex including a child) other privacy violations (forcing the child to undress, spying on a child in the bathroom or bedroom) sexual exploitation enticing children to pornographic sites or material on the Internet luring children through the Internet to meet for sexual liaisons exposing children to pornographic movies or magazines child prostitution using a child in the production of pornography, such as a film or magazine Who are Sexual Abusers • • • • • • Sexual abusers can be: parents, siblings, or other relatives childcare professionals clergy, teachers, or athletic coaches neighbors or friends strangers What is emotional abuse? • Emotional abuse is any attitude, behavior, or failure to act on the part of the caregiver that interferes with a child's mental health or social development. • Other names for emotional abuse are: • verbal abuse • mental abuse • psychological maltreatment or abuse What is neglect? • Neglect is a failure to provide for the child's basic needs. The types of neglect are: • physical • educational • emotional Causes of Child Abuse • Cyclical effect: 0ver 70% of abusers were abused themself • general stress • the stress of having children in the family, when one didn't have children before • dealing with a child who has a disability or difficult behaviors • the stress of caring for someone besides oneself • alcohol or drug use • marital conflict • unemployment Variations in Development • Different children develop at different rates • The same child will vary in rate of their own development at different times in their life • Understanding the variance and range of developmental rates is important to developmental psychologists Stage theories of development • Do we develop in stages or not? Are we like oak trees or butterflies in our development? – is our development continuous or discontinuous? • There are a number of various “stage” theorists in study of developmental psychology Stage Theories Piaget’s stage theory of cognitive development • Piaget’s interest was in identifying particular eras (stages) of cognitive style (development) in humans • He distinguished 4 stages; they are: – – – – sensiomotor stage: 0-2 years preoperational stage: 3-6 years concrete operations stage: 7-11 years formal operations stage: 12+ years Piaget’s Stages of Cognitive Development Typical Age Range Description of Stage Developmental Phenomena Birth to nearly 2 years Sensorimotor Experiencing the world through senses and actions (looking, touching, mouthing) •Object permanence •Stranger anxiety •Grasping & sucking items (explore) About 2 to 6 years Preoperational Representing things with words and images but lacking logical reasoning •Pretend play •Egocentrism •Language development About 7 to 11 years Concrete operational •Conservation Thinking logically about concrete •Mathematical events; grasping concrete analogies transformations and performing arithmetical operations About 12 through adulthood Formal operational Abstract reasoning •Abstract logic •Potential for moral reasoning Infancy and Childhood: Piaget’s Cognitive Development Object Permanence the awareness that things continue to exist even when not perceived Infancy and Childhood: Piaget’s Cognitive Development Baby Mathematics Shown a numerically impossible outcome, infants stare longer (Wynn, 1992) 4. Possible outcome: Screen drops, revealing one object. 1. Objects placed in case. 2. Screen comes 3. Object is removed. up. 4. Impossible outcome: Screen drops, revealing two objects. Infancy and Childhood: Piaget’s Cognitive Development Conservation the principle that properties such as mass, volume, and number remain the same despite changes in the forms of objects Stage theories of moral development • There are 2 theorists concerned with identification of stages of moral development in humans – Kohlberg’s theory of moral development – Piaget’s Theory of moral development • Theories of moral development concern how does one learn to do the “right” thing in society Kohlberg’s theory • Kohlberg’s theory of moral development includes 3 general phases (stages) of morality that persons can develop. They are: – the premoral level of morality – the conventional level of morality – the postconventional level of morality • Why do you do the right thing? Kohlberg’s Moral Ladder Postconventional level Morality of abstract principles: to affirm agreed-upon rights and personal ethical principles Conventional level Morality of law and social rules: to gain approval or avoid disapproval Preconventional level Morality of self-interest: to avoid punishment or gain concrete rewards As moral development progresses, the focus of concern moves from the self to the wider social world. Jean Piaget theory of moral development • External motivation • Morality of constraint • Point of view: black and white • Rules: sacred unalterable • Punishment: harsh and immediate; defines the act • Intentionality: the outcome determines right or wrongness of act • Authority: unilateral respect • • • • Internal motivation Morality of cooperation Point of view: shades of grey Rules; made by people, broken or changed by people. • Punishment: want less severe, more reciprocal • Intentionality: the motivation behind the act determines it regardless of outcome. • Authority: value peers and adults equally Erik Erikson’s Theory • Erikson’s stage theory of personality development – there are eight (8) stages of development – each stage has a “crisis” to be resolved that has a profound effect on how a person’s personality will develop in the long term – these stages start at birth and go to old age Erik Erikson’s Theory • The 8 stages are: 1. basic trust vs mistrust: 0-1 year – “the world is a good place and I can trust people” 2. autonomy vs shame/doubt: 1-3 years – “I’m gonna stand up to the big people….did I go too far?” 3. initiative vs guilt: 3-5 years – “I got a bright idea and I’m gonna do it!” 4. industry vs inferiority: 5-11 years 5. identity vs role confusion: 11-18 years 6. intimacy vs isolation: 18-40 years 7. generativity vs stagnation: 40-65 years 8. integrity vs despair: 65+ years Erikson’s Stages of Psychosocial Development Approximate age Stage Description of Task Infancy (1st year) Trust vs. mistrust If needs are dependably met, infants develop a sense of basic trust. Toddler (2nd year) Autonomy vs. shame Toddlers learn to exercise will and and doubt do things for themselves, or they doubt their abilities. Preschooler (3-5 years) Initiative vs. guilt Preschoolers learn to initiate tasks and carry out plans, or they feel guilty about efforts to be independent. Elementary (6 yearspuberty) Competence vs. inferiority Children learn the pleasure of applying themselves to tasks, or they feel inferior. Erikson’s Stages of Psychosocial Development Approximate age Stage Description of Task Adolescence (teens into 20’s) Identity vs. role confusion Teenagers work at refining a sense of self by testing roles and then integrating them to form a single identity, or they become confused about who they are. Young Adult (20’s to early 40’s) Intimacy vs. isolation Young adults struggle to form close relationships and to gain the capacity for intimate love, or they feel socially isolated. Middle Adult (40’s to 60’s) Generativity vs. stagnation The middle-aged discover a sense of contributing to the world, usually through family and work, or they may feel a lack of purpose. Late Adult (late 60’s and up) Integrity vs. despair When reflecting on his or her life, the older adult may feel a sense of satisfaction or failure. Development in Infancy and Childhood Development in infancy and childhood • The neonatal period: the newborn’s first two (2) weeks The Neonate • Cognitive development – neonates can imitate facial expressions fairly soon – neonates have some memory for visual forms • • • • they prefer to look at contrasts they prefer order to disorder they prefer to look at patterns they prefer to look at human faces Prenatal Development and the Newborn Rooting Reflex tendency to open mouth, and search for nipple when touched on the cheek Preferences human voices and faces facelike images--> smell and sound of mother preferred The Newborn Greater stimulation with looking at a drawing of a face Habituation Decreasing responsiveness with repeated stimulation Habituate more quickly to a face-like image than to a solid disk The beginnings of cognition Prenatal Development and the Newborn Having habituated to the old stimulus, newborns preferred gazing at a new one The Neonate • Emotional and social development of the neonate – five (5) emotional states can be distinguished in the neonate. These states are: • • • • • surprise happiness discomfort distress interest Infancy and Childhood: Physical Development Babies only 3 months old can learn that kicking moves a mobile--and can retain that learning for a month (RoveeCollier, 1989, 1997). Infancy and Childhood: Piaget’s Cognitive Development Cognition all the mental activities associated with thinking, knowing, remembering, and communicating Schema a concept or framework that organizes and interprets information & experiences Infancy and Childhood: Piaget’s Cognitive Development Assimilation interpreting one’s new experience in terms of one’s existing schemas Accommodation Adapting/adjusting one’s current understandings (schemas) to incorporate new information Infancy: 2 weeks to 2 years • Emotional and social development in infancy – infant develops a “social smile” at about 2 months of age – develops “separation anxiety” at about 6-9 months of age – develops “stranger anxiety” at about 6-10 months of age – these anxieties peak around 14 months and gradually decline by about age 2 Early Childhood: 2 to 7 years Emotional and social development • Emotional and social development: 2-7 years – child progresses from solitary play to parallel play and finally to cooperative play – child incorporates others into his/her pretending and games become more rulegoverned Middle Childhood: 7-11 years Emotional and social development – peers become increasingly more important during this time – school becomes increasingly important – child’s early dependence on parents begins to lessen; parents may have some difficulty accepting this change Adolescence 12-13 through18-19 years of age Adolescence Adolescence the transition period from childhood to adulthood extending from puberty to independence Puberty (girls: 11 years old; boy: avg. 13 years old) the period of sexual maturation when a person becomes capable of reproduction Surge of physical growth Adolescence Primary Sex Characteristics body structures that make sexual reproduction possible ovaries--female testes--male external genitalia Secondary Sex Characteristics nonreproductive sexual characteristics female--breast and hips male--voice quality and body hair Menarche 1st menstration (12-13) Spermarche 1st ejaculation (13-14) Adolescent Issues Adulthood: Young adulthood through older adulthood Cognitive development • • • • • Cognitive abilities improve, change, or decline during adulthood Crystallized Intelligence: accumulated knowledge as reflected in vocabulary and analogies Fluid Intelligence: ability to reason speedily and abstractly, as when solving novel logic problems Crystallized intelligence improves over time while fluid intelligence slowly wanes Wisdom improves; wisdom is the appropriate use of knowledge Emotional and social development • Erickson: Early adulthood: Intimacy vs Isolation; • Styles of Marriage STYLES OF MARRIAGE • Conflict-Habituated: patterns of conflict creates excitement and drives marriage • Passive-Congenial: means to an end, background to true life forces • Devitalized: social commitment, going through the motions • Vital: romantic, closeness, separate id’s • Total: complete and total togetherness psychosomatic MIDDLE ADULTHOOD Middle adulthood: Erickson’s Generativity vs stagnation; the challenge is to find meaning in our work and family lives and to continue to be productive Mid-Life Issues MID-LIFE ISSUES • Emotional and social development • Climacteric: period beginning about age 45 when a loss of the capacity to sexually reproduce in women and a decline in the reproductivity capacity in men occurs • Mid-life crisis: Empty nest, menopause The Aged Adult OLD AGE/LATE ADULTHOOD • Gerontology: the study of old age • Later adulthood: Erickson’s Integrity vs despair; the challenge is to see a life with meaning and continued satisfaction Causes of Aging • Aging is partly a biological process but is a psychological process as well • Staying engaged in life’s activities and refusing to accept myths about aging are two keys to happy aging • Aging as a biological process may be genetically solved toward the end of your lifetime Evaluation of stage theories of adulthood • Psychologists disagree as to whether the changes in adulthood can be thought of as a series or stages or just a continuation of a single process • This is a “continuity vs discontinuity” debate that often occurs in developmental psychology • What do you think? Death and dying: The final stage Death and dying • According to Elisabeth Kubler-Ross, the stages in the acceptance of impending death are describes as the Grief Cycle: – – – – – denial anger bargaining depression acceptance Types of Death • Social death: loss of socialization and interaction with outside world • Psychological death: loss of autonomy and decision making, confused or disoriented • Biological death: actual physical death: problems with biological death: artificial means of sustaining life, technological advancements preventing natural death Death and Dying • One step beyond? – what happens at the point of death? – what happens after death? – the “near death experience” and the commonalities in these reports • rushing down a tunnel which, at the end, has an intensely brilliant light • reports of seeing dead loved ones and experiences with angelic beings and/or God Practice Test 1.
