New cards
Developmental Psychology
a branch of psychology that studies physical, cognitive, and social change throughout the life span.

fetal alcohol syndrome
physical and cognitive abnormalities in children caused by a pregnant woman’s heavy drinking. In severe cases, signs include a small, out-of-proportion head and abnormal facial features.
7

habituation
decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a visual stimulus, their interest wanes and they look away sooner.
8

cognition
all the mental activities associated with thinking, knowing, remembering, and communicating.

maturation
biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience.

object permanence
the awareness that things continue to exist even when not perceived.

formal operational stage
in Piaget’s theory, the stage of cognitive development (normally beginning about age 12) during which people begin to think logically about abstract concepts.

parents impose rules and expect obedience: “Don’t interrupt.” “Keep your room clean.” “Don’t stay out late or you’ll be grounded.” “Why? Because I said so.”
31
New cards
permissive
parents submit to their children’s desires. They make few demands and use little punishment.
