He believed that their learning starts through accidental encounters with the world, and that infants gradually develop deliberate or intentional behavior as they learn about cause and effect, and construct mental “schemes” about how the world works. He divided the Sensorimotor period into 6 sub-stages. New research suggests that Piaget underestimated the cognitive abilities of young infants. For example, it is possible that awareness of object permanence begins around three months, instead of eight months as Piaget said. A theory based on the new research is called core knowledge perspective; it holds that infants have more prewired or built-in understanding than Piaget realized. The new research and theory are still controversial. We do know that infants learn through observation and imitation as well as through active exploration, and that experiences (with people objects, language, etc.) are essential for learning. Over the first two years of life, changes in infants’ memory and attention (which result from changes in the brain combined with appropriate external stimulation), contribute to their increasing cognitive and language ability. Infant learning does not take place in a vacuum. It is enhanced by the support and guidance of the people in their lives. Infants whose parents are loving and encouraging, talk to them and play with them, score higher on mental tests. Early intervention and enrichment can increase the abilities of children from deprived backgrounds. Since a stimulating and responsive environment has been shown to be important, infant and toddler child care should be required to meet high standards. Standards for quality vary widely from state to state in the U.S. Developmentally appropriate programs best meet the needs of infants and toddlers. There are several theories about how young children first learn language. The interactionist view holds that both built-in language ability in the human brain and imitation of spoken language are responsible. A language rich environment promotes strong language and cognitive development. That is an environment in which infants and toddlers hear language frequently, are warmly spoken to and encouraged to respond, and are played with in an interactive turn-taking manner. Television is not an effective part of a rich language or learning environment for infants and toddlers. The American Academy of Pediatrics discourages all forms of screen time for children two or younger.

It happens 2 ways. 1. When we use our current schemes to interpret the world, that’s ______________________________________________________ . 2. When we make new schemes, or change old ones to fit new information, that’s _______________________________________________________ . There are six sub stages of the Sensorimotor period.

List 3 of these aspects: ___________________, ___________________, ____________________________ Habituation / recovery research studies show that infants also learn and remember a wide variety of information just by watching objects and events. Infants do not always have to be ___________________ _____________ to acquire new information. Distinguish between recognition memory and recall memory: Recognition:____________________________________________________________ Recall:_________________________________________________________________ SOCIAL CONTEXT OF EARLY COGNITIVE DEVELOPMENT Lev Vygotsky suggested that which skills we learn and how we learn them reflect the values of the societies in which we live. He theorized that complex mental activities, such as voluntary attention, deliberate memory, categorization and problem solving have their origins in ________ _____________. Think of an example in which a more mature member of the child’s society (say an older sibling or parent) helps a child master an activity: _____________________________________________________________________ INDIVIDUAL DIFFERENCES IN EARLY MENTAL DEVELOPMENT The goal of mental tests is to 1. measure __________________________________________________________ 2. predict ___________________________________________________________ IQ tests for any age individual compute scores by comparing the individual’s performance to ________________________________________________________. Despite careful construction, infant IQ tests are poor predictors of intelligence. Infants performance on tests do not always reflect their true abilities – why? (3 reasons) ______________________________________________________________________ These tests can be useful for screening – briefly explain why that is valuable: _______________________________________________________________________ _______________________________________________________________________ Look at the “Features of a High Quality Home Life” table on page 229 in the Berk text. What 6 home factors were shown to have a significant positive impact on infant IQ? 1. 2. 3. 4. 5. 6. When these 6 features are studied in the home environment, how does heredity (inherited intelligence) also become a factor that needs to be considered? ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ How should Vanessa, the mother of Timmy in the textbook story (pages 227 and 229), change her child rearing practices to better support Timmy’s mental development? ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ Think about this: What kinds of programs could our society offer to make sure that all parents learn about effective child rearing practices? ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ Many American children are in full time child care from infancy.

The process through which the child acquires and uses knowledge of the world. Their state of alertness and their well being affects their ability to respond to the world. A well-fed child in the quiet alert state is the most attentive. The 3 facets of cognitive development are perception, memory and problem solving. I. Perception is the cognitive process of receiving and analyzing information provided by the 5 senses. All infants attend to some kinds of stimuli more than others. These preferences are called perceptual biases. Name one infant perceptual bias for each of the 5 senses: Hearing – prefer sounds with variety Vision – prefer high contrast, black/white or red Touch – prefer gentle touch; do feel pain Smell – prefer smell of own mother Taste – prefer sweet; can also taste salty, sour and bitter Infants actively seek stimulation, and try to regulate the amount of stimulation they receive. Too little: they actively seek more Too much: they turn away, lower their eyes. Stages of Learning About a New Object: 1. random manipulation 2. gross exploration 3. minute examination 4. practice making object move 5. experiment 6. use this information for exploring new things Schemata = perceptual representation of the events and objects around them Discrepancy principle= once a child has developed a schema for an object, she will pay most attention to a new object that is moderately different from what she is already familiar with. Habituation= waning of a response to a stimulus Recovery (Dishabituation) = rekindled interest in a new or different stimulus Physiological indicators of an infant’s recovered interest include: looking, motor behavior (like foot jiggling), sucking, increased respiration and heart rate Habituation tells us that infants can: 4. detect changes in their environment 5. discriminate between stimuli 6. remember a stimulus What is object permanence? The infant’s understanding that objects and people continue to exist when out of sight. At what age did Piaget believe that infants develop object permanence? 8- 9 months – but new research suggests it begins much younger. II. Memory Recognition or receptive memory: child remembers (recognizes) an object when he sees it again. Recall or expressive memory: child can conjure up a mental image of an object, person or event III. Problem Solving Infant problem solving is influenced by 1. perception 2. memory 3. child’s maturation Jean Piaget believed that as infants mature, they move toward a more efficient solving of real world problems.
