Developmental Psychology

Developmental Psychology

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

Zygote

the fertilized egg; it enters a 2-week period of rapid cell division and develops into an embryo.

Embryo

Fetus

the developing human organism from 9 weeks after conception to birth.

Teratogens

agents, such as chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause harm.

Fetal Alcohol Syndrome (FAS)

physical and cognitive abnormalities in children caused by a pregnant woman's heavy drinking. In severe cases, symptoms include noticeable facial misproportions.

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.

Maturation

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

Cognition

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

Schema

a concept or framework that organizes and interprets information.

Assimilation

interpreting our new experience in terms of our existing schemas.

Accommodation

Development - adapting our current understandings (schemas) to incorporate new information.

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.

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.

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.

Egocentrism

in Piaget's theory, the preoperational child's difficulty taking another's point of view.

Theory of Mind

people's ideas about their own and others' mental states—about their feelings, perceptions, and thoughts, and the behaviors these might predict.

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.

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.

Autism

a disorder that appears in childhood and is marked by deficient communication, social interaction, and understanding of others' states of mind.

Stranger Anxiety

the fear of strangers that infants commonly display, beginning by about 8 months of age.

Attachment

an emotional tie with another person; shown in young children by their seeking closeness to the caregiver and showing distress on separation.

Critical Period

an optimal period shortly after birth when an organism's exposure to certain stimuli or experiences produces proper development.

Imprinting

the process by which certain animals form attachments during a critical period very early in life.

Temperament

a person's characteristic emotional reactivity and intensity.

Basic Trust

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.

Self-Concept

Gender

in psychology, the biologically and socially influenced characteristics by which people define male and female.

X Chromosome

the sex chromosome found in both men and women. Females have two of these; males have one. One chromosome from each parent produces a female child.

Y Chromosome

the sex chromosome found only in males. When paired with an X chromosome from the mother, it produces a male child.

Testosterone

the most important of the male sex hormones. Both males and females have it, but the additional levels in males stimulates the growth of the male sex organs in the fetus and the development of the male sex characteristics during puberty.

Role

a set of expectations (norms) about a social position, defining how those in the position ought to behave.

Gender Typing

the acquisition of a traditional masculine or feminine role.

Social Learning Theory

the theory that we learn social behavior by observing and imitating and by being rewarded or punished.

Adolescence

the transition period from childhood to adulthood, extending from puberty to independence.

Puberty

the period of sexual maturation, during which a person becomes capable of reproducing.

Primary Sex Characteristics

the body structures (ovaries, testes, and external genitalia) that make sexual reproduction possible.

Secondary Sex Characteristics

nonreproductive sexual characteristics, such as female breasts and hips, male voice quality, and body hair.

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.

Social Identity

the "we" aspect of our self-concept; the part of our answer to "Who am I?" that comes from our group memberships.

Cross-Sectional Study

a study in which people of different ages are compared with one another.

Longitudinal Study

research in which the same people are restudied and retested over a long period.

Crystallized Intelligence

our accumulated knowledge and verbal skills; tends to increase with age.

Fluid Intelligence
