 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 | the developing human organism from about 2 weeks after fertilization through the second month |
| fetus | the developing human organism from 9 weeks after conception to birth |
| teratogens | agents, such as chemicals and viruses, that can reach the embryo/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 |
| 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 |
| schema | a concept or framework that organizes and interprets information |
| assimilation | interpreting our new experiences in terms of our existing schemas |
| accommodation | adapting our current understandings to incorporate new information |
| sensorimotor stage | in Piaget's theory, the stage (from birth to about 2 years) 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) 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 part of concrete 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 preopertional 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 years to 11 years) 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 about 8 months old |
| 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 | our understanding and evaluation of who we are |
| gender | in psychology, the biologically and socially influenced characteristics by which people define male and female |
| aggression | physical or verbal behavior intended to hurt someone |
| X chromosome | the sex chromosome found in both men and women; females have 2, men have 1; one from each parent produces a female child |
| Y chromosome | the sex chromosome found only in males |
| role | a set of expectations (norms) about a social position, defining how those in the position ought to behave |
| gender role | a set of expected behaviors for males or females |
| gender identity | our sense of being male or female |
| 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, dring which a person becomes capable of reproducing |
| primary sex characteristics | the body structures that make sexual reproduction possible |
| secondary sex characteristics | nonreproductive sexual characteristics |
| menarche | the first menstrual period |
| 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 |
| intimacy | in Erikson's theory, the ability to form close, loving relationships; a primary developmental task in late adolescence and early adulthood |
| emerging adulthood | for some people in modern cultures, a period from the late teens to mid-20s, bridging the gap between adolescent dependence and full independence and responsible adulthood |
| menopause | the time of natural cessation of menstruation; also refers to the biological changes a woman experiences as her ability to reproduce declines |
| 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 | our ability to reason speedily and abstractly; tend to decrease during late adulthood |
| social clock | the culturally preferred timing of social events |
| placenta | forms as the zygote's outer cells attach to the uterine wall; transfers nutrients and oxygen from mother to fetus |
| authoritarian | parents impose rules and expect obedience |
| permissive | parents submit to their children's desires |
| authoritative | parents are both demanding and responsive. they exert control by setting rules and enforcing them but they also explain the reasons for the rules and they encourage open discussion when making rules and allow expectation |
| gray matter | the neural bodies |
| white matter | the axons and dendrites |
| preconventional morality | before age 9, most children's morality focuses on self-interest. they object rules either to avoid punishment or to gain concrete rewards |
| conventional morality | by early adolescence, morality focuses on caring for others and on upholding laws and social rules, simply because they are the laws and rules |
| postconventional morality | with the abstract reasoning of formal operational thought, people may reach a third moral level. actions are judged "right" because they flow from people's right or from self-defined, basic ethical principles |
| telomeres | chromosome tips |
| generativity | being productive and supporting future generations |
| integrity | a feeling that one's life has been meaningful and worthwhile |
