Developing Through the Life Span Flashcards
embryo
the developing human organism from about 2 weeks after fertilization through the second month.
assimilation
interpreting our new experiences in terms of our existing schemas.
preoperational stage
in Piaget’s theory, the stage (from about 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.
developmental psychology
a branch of psychology that studies physical, cognitive, and social change throughout the life span.
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.
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.
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.
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.
menarche
the first menstrual period.
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.
longitudinal study
research in which the same people are restudied and retested over a long period.
teratogens
(literally, “monster maker”) agents, such as chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause harm.
autism
a disorder that appears in childhood and is marked by deficient communication, social interaction, and understanding of others’ states of mind.
accommodation
adapting our current understandings (schemas) to incorporate new information.
fetus
the developing human organism from 9 weeks after conception to birth.
secondary sex characteristics
nonreproductive sexual characteristics, such as female breasts and hips, male voice quality, and body hair.
cross-sectional study
a study in which people of different ages are compared with one another.
imprinting
the process by which certain animals form attachments during a critical period very early in life.
attachment
an emotional tie with another person; shown in young children by their seeking closeness to the caregiver and showing distress on separation.
intimacy
in Erikson’s theory, the ability to form close, loving relationships; a primary developmental task in late adolescence and early adulthood.
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.
critical period
an optimal period early in the life of an organism when exposure to certain stimuli or experiences produces normal development.
zygote
the fertilized egg; it enters a 2-week period of rapid cell division and develops into an embryo.
cognition
all the mental activities associated with thinking, knowing, remembering, and communicating.
