PSY 220 Lecture 16: Chapter 16
Document Summary
Theme 1:nature and nurture:all interactions, all the time: nature and nurture begin interacting before birth: A host of environmental factors, including teratogens, influence prenatal development. Their effects depend in part on maternal and fetal genetic characteristics and the interactions among them. Even qualities that are present at birth, such as taste preferences and maternal voice recognition, may be affected by experience as well as by nature: infants" nature elicits nurture: Nature equips babies with a host of qualities that elicit appropriate nurture from parents and other caregivers: timing matters: The effects of a given kind of nurture depend on the nature of the organism at the time of the experience, both before and after birth. For example, infants born with strabismus (i. e. , cross- eyed) develop normal depth perception only if the surgery is done very early in life. Such sensitive periods influence perception, language, emotions, and social behavior: nature does not reveal itself all at once.
