stranger anxiety

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

attachment

an emotional tie with others; shown in young children by their seeking closeness to caregivers and showing distress on separation.

imprinting

the process by which certain animals form strong attachments during early life

strange situation

a procedure for studying child-caregiver attachment; a child is placed in an unfamiliar environment while their caregiver leaves and then returns, and the child's reactions are observed.

secure attachment

demonstrated by infants who comfortably explore environments in the presence of their caregiver, show only temporary distress when the caregiver leaves, and find comfort in the caregiver's return.

insecure attachment

demonstrated by infants who display either a clinging, anxious attachment or an avoidant attachment that resists closeness.

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

all our thoughts and feelings about ourselves in answer to the question, "Who am I?"

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 young adulthood.

emerging childhood

a period from about age 18 to the mid-twenties, when many persons in Western cultures are no longer adolescents but have not yet achieved full independence as adults.

social clock

the culturally preferred timing of social events such as marriage, parenthood, and retirement.
