Cognitive Development during the First Three Years Chapter 5 © 2012 by the McGraw-Hill Companies, Inc Guideposts for Study 1) What are the six approaches to the study of cognitive development? 2) How do infants learn, and how long can they remember? 3) Can infants’ and toddlers’ intelligence be measured, and how can it be improved? 4) How did Piaget explain early cognitive development, and how well have his claims stood up? © 2012 by the McGraw-Hill Companies, Inc Guideposts for Study 5) How can we measure infants’ ability to process information, and when do infants begin to understand characteristics of the physical world? 6) What can brain research reveal about the development of cognitive skills? 7) How does social interaction with adults advance cognitive competence? 8) How do babies develop language, and what influences contribute to linguistic progress? © 2012 by the McGraw-Hill Companies, Inc Behaviorist Approach l Babies are born with the ability to learn l Classical
