according to Erik Erikson, a sense that the world is predictable and trustworthy; said to be formed during infancy by appropriate experiences with responsive caregivers.
Carol Gilligan
developmental psychologist who believed that females tend to differ from males both in being less concerned with viewing themselves as separate individuals and in being more concerned with "making connections"
Cognition
all mental activities associated with thinking, knowing, remembering, and communicating.
concrete operational stage
in Piaget's theory, the stage of cognitive development (from about 6 or 7 to 11 years of age) during which children gain the mental operations that enable them to think logically about concrete events.
conservation
the principle (which Piaget believed to be a part of concrete operational reasoning) that properties such as mass, volume, and number remain the same despite changes in the forms of objects.
Critical Period
an optimal period early in the life of an organism when exposure to certain stimuli or experiences produces normal development.
Cross-Sectional Study
a study in which people of different ages are compared with one another.
Developmental Psychology
a branch of psychology that studies physical, cognitive, and social change throughout the life span
Diana Baumrid
pioneering parenting-style researcher, who conducted research on the different styles of parenting; contributed to research that finds that children with highest self-esteem/capability are those with parents who are warm, concerned, and authoritative
egocentrism
In Piaget's theory, the preoperational child's difficulty taking another's point of view.
embryo
the developing human organism from about 2 weeks after fertilization through the second month.
emerging adulthood
for some people in modern cultures, a period from the late teens to mid-twenties, bridging the gap between adolescent dependence and full independence and responsible adulthood.
Erik Erikson
theories who contended that each stage of life has its own psychosocial task, a crisis that needs resolution
Fetal Alcohol Syndrome (FAS)
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.

Gender Identity
our sense of being male or female
Gender Role
a set of unexpected behaviors for males or for females.
Gender Typing
the acquisition of a traditional masculine or feminine role.
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.
Harry Harlow
along with Margaret Harlow, bred monkeys for learning studies; discovered that baby monkeys will prefer a fake mother who is soft and fuzzy over one that is cold and wiry, even if the wiry one is the one that is providing the nourishment
identity
our sense of self; according to Erikson, the adolescent's task is to solidify a sense of self by testing and integrating various roles.
Imprinting
the process by which certain animals form strong attachments during an early-life critical period.
intimacy
in Erikson's theory, the ability to form close, loving relationships; a primary developmental task in late adolescence and early adulthood.
Jean Piaget
development psychologist who studied children's cognitive development (all the mental activities associated with thinking, knowing, remembering, and communicating); he came up with the four-stage theory of cognitive development
Konrad Lorenz
explored the rigid attachment process (called imprinting) that occurs during the "critical period"
Lawrence Kohlberg
along with Jean Piaget, proposed that moral reasoning (the thinking that occurs as we considering right and wrong) guides moral actions

longitudinal study
research in which the same people are restudied and retested over a long period.
Margaret Harlow
along with Harry Harlow, bred monkeys for learning studies; discovered that baby monkeys will prefer a fake mother who is soft and fuzzy over one that is cold and wiry, even if the wiry one is the one that is providing the nourishment
Mary Ainsworth
designed the strange situation experiment; found that about 60 percent of infants display secure attachment (in their mother's presence they play comfortably, even in a strange new environment, but when she leaves, they become distressed and seek contact with her)
maturation
biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience.
menarche

menopause
the time of natural cessation of menstruation; also refers to the biological changes a woman experiences as her ability to reproduce declines.
object permanence
the awareness that things continue to exist even when not perceived
preoperational stage
in Piaget's theory, the stage (from 2 to about 6 or 7 years of age) during which a child learns to use language but does not yet comprehend the mental operations of concrete logic.

Role
a set of expectations (norms) about a social position, defining how those in the position ought to behave.
Schema
a concept or framework that organizes and interprets information.
secondary sex characteristics
nonreproductive sexual characteristics, such as female breasts and hips, male voice quality, and body hair.

sensorimotor stage
in Piaget's theory, the stage (from birth to about 2 years of age) during which infants know the world mostly in terms of their sensory impressions and motor activities.
Sexual Orientation
an enduring sexual attraction toward members of either one's own sex (homosexual orientation), the other sex (heterosexual orientation), or both sexes (bisexual orientation).

Stranger Anxiety
the fear of strangers that infants commonly display, beginning by about 8 months of age.
temperament
a person's characteristic emotional reactivity and intensity.
teratogens
agents, such as chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause harm (literally means "monster maker")
