Key Elements of Piaget’s Theory Action = Knowledge Four universal stages in fixed order Development = physical maturation and exposure to relevant experiences Schemes adapt and change 107

Discovering the Lifespan - Robert S. Feldman Copyright © 2009 Pearson Education, Inc., Upper Saddle River, NJ 07458. All rights reserved. At each stage, child’s mind develops in a new way from simple to complex Organization: tendency to create increasingly complex cognitive structures (system of knowledge; ways of thinking that incorporate more and more accurate images of reality Schemas: organized patterns of behavior that a person uses to think about and act in a situation.

Discovering the Lifespan - Robert S. Feldman Copyright © 2009 Pearson Education, Inc., Upper Saddle River, NJ 07458. All rights reserved. What principles underlie this cognitive growth? Assimilation Accommodation 108

Discovering the Lifespan - Robert S. Feldman Copyright © 2009 Pearson Education, Inc., Upper Saddle River, NJ 07458. All rights reserved. Adaptation: how children handle new information in light of what they already know Assimilation: taking new information and incorporating it into existing cognitive structures (sucking on sippie cup versus breats) Accommodation: adjusting one’s cognitive structures to fit new information (sipping from cup/glass, changes how uses tongue/mouth)

A Closer Look Substage 1: Simple Reflexes First month of life –Various various inborn reflexes At center of a baby’s physical and cognitive life Determine nature of infant’s interactions with world –At the same time, some of reflexes begin to accommodate the infant’s experiences 109

Discovering the Lifespan - Robert S. Feldman Copyright © 2009 Pearson Education, Inc., Upper Saddle River, NJ 07458. All rights reserved. A Closer Look Substage 2: First Habits and Primary Circular Reactions 1 to 4 months of age Beginning of coordination of what were separate actions into single, integrated activities. Activities that engage baby’s interests are repeated simply for sake of continuing to experience it –Circular reaction –Primary circular reaction 109

Discovering the Lifespan - Robert S. Feldman Copyright © 2009 Pearson Education, Inc., Upper Saddle River, NJ 07458. All rights reserved. Substage 3: Secondary Circular Reactions 4 to 8 months of age Child begins to act upon outside world Infants now seek to repeat enjoyable events in their environments that are produced through chance activities Secondary circular reactions A Closer Look 110

Discovering the Lifespan - Robert S. Feldman Copyright © 2009 Pearson Education, Inc., Upper Saddle River, NJ 07458. All rights reserved. Assessing Piagetian Theory PROS Descriptions of child cognitive development accurate in many ways –Piaget was pioneering figure in field of development –Children learn by acting on environment –Broad outlines of sequence of cognitive development and increasing cognitive accomplishments are generally accurate CONS Substantial disagreement over validity of theory and many of its specific predictions –Stage conception questioned –Connection between motor development and cognitive development exaggerated –Object permanence can occur earlier under certain conditions –Onset of age of imitation questioned –Cultural variations not considered 111

Discovering the Lifespan - Robert S. Feldman Copyright © 2009 Pearson Education, Inc., Upper Saddle River, NJ 07458. All rights reserved. Review and Apply REVIEW Piaget’s theory of human cognitive development involves a succession of stages through which children progress from birth to adolescence. As infants move from one stage to another, the way they understand the world changes. 113

Discovering the Lifespan - Robert S. Feldman Copyright © 2009 Pearson Education, Inc., Upper Saddle River, NJ 07458. All rights reserved. Review and Apply REVIEW The sensorimotor stage, from birth to about 2 years, involves a gradual progression through simple reflexes, single coordinated activities, interest in the outside world, purposeful combinations of activities, manipulation of actions to produce desired outcomes, and symbolic thought. The sensorimotor stage has six substages. 113

Discovering the Lifespan - Robert S. Feldman Copyright © 2009 Pearson Education, Inc., Upper Saddle River, NJ 07458. All rights reserved. Review and Apply REVIEW Information processing approaches consider quantitative changes in children’s abilities to organize and use information. Cognitive growth is regarded as the increasing sophistication of encoding, storage, and retrieval. Infants clearly have memory capabilities from a very early age, although the duration and accuracy of such memories are unresolved questions. Traditional measures of infant intelligence focus on behavioral attainments, which can help identify developmental delays or advances. 120

Discovering the Lifespan - Robert S. Feldman Copyright © 2009 Pearson Education, Inc., Upper Saddle River, NJ 07458. All rights reserved. Origins of Language Development Interactionist Approaches: Language as a Social Device Specific course of language development is determined by the language to which children are exposed and reinforcement they receive for using language in particular ways Social factors are key to development 125

One of you is a 8-month-old infant; the other is a parent. As the parent, ask your “infant” classmate: “Would you like a cookie?”

Discovering the Lifespan - Robert S. Feldman Copyright © 2009 Pearson Education, Inc., Upper Saddle River, NJ 07458. All rights reserved. How does this speech change? Infant-directed speech changes as children become older –Around the end of the first year, takes on more adult- like qualities –Sentences become longer and more complex, although individual words are still spoken slowly and deliberately –Pitch used to focus attention on important words 126

Infant-directed speech plays an important role in infants’ acquisition of language –Occurs all over the world, though there are cultural variations –Preferred by newborns –Babies who are exposed to a infant-directed speech early in life seem to begin to use words and exhibit other forms of linguistic competence earlier 126

Developmental Diversity Do people everywhere say “ba-ba-boo” to their infants?

Becoming an Informed Consumer of Development Based upon findings of developmental researchers, infant cognitive development may be promoted by: Providing infants the opportunity to explore the world Being responsive to infants on both a verbal and a nonverbal level Asking questions, listening to their responses, and providing further communication Reading to infants Keeping in mind that you don’t have to be with an infant 24 hours a day Not pushing infants and don’t expect too much too soon 127

Discovering the Lifespan - Robert S. Feldman Copyright © 2009 Pearson Education, Inc., Upper Saddle River, NJ 07458. All rights reserved. Review and Apply REVIEW Before they speak, infants understand many adult utterances and engage in several forms of prelinguistic communication. Children typically produce their first words between 10 and 14 months, and rapidly increase their vocabularies from that point on, especially during a spurt at about 18 months. 128

Discovering the Lifespan - Robert S. Feldman Copyright © 2009 Pearson Education, Inc., Upper Saddle River, NJ 07458. All rights reserved. Review and Apply REVIEW Learning theorists believe that basic learning processes account for language development, whereas nativists like Noam Chomsky and his followers argue that humans have an innate language capacity. The interactionists suggest that language is a consequence of both environmental and innate factors. 128
