Developmental Psychology Overview 
Developmental psychologists study the life cycle, from conception to death, examining how we develop physically, cognitively, and socially.  This unit covers prenatal, infant, and childhood development and introduces three major issues in developmental psychology: (1) the relative impact of genes and experience on behavior, (2) whether development is best described as gradual and continuous or as a discontinuous sequence of stages, and (3) whether the individual’s personality remains stable or changes over the life span.

Research and theoretical issues introduced in this unit are the foundation of the overarching developmental unit.  Pay particular attention to the research of Piaget on cognitive development, Harlow and others on attachment and social deprivation, and to the studies of twins and adopted children.

A key assumption of modern developmental psychology is that development is lifelong.  The Development unit explores physical, cognitive, and social development during adolescence and adulthood.  On the basis of this discussion, this unit will revisit the issue of continuity in development.  Although there are not too many terms to learn in this chapter, there are a number of important research findings to remember.  Pay particular attention to the discussions regarding intellectual stability or decline and social changes during adulthood.  A major challenge in this unit is to become familiar with two stage theories: Kohlberg’s theory of moral development and Erikson’s theory of psychosocial development.
