Chapter 4 Flashcards
A branch of psychology that studies physical, cognitive, and social development throughout the life span
Developmental Psychology
Research that compares people of different ages at the same point in time.
Cross-sectional Studies
Research that follows and retests the same people over time.
Longitudinal Studies
The fertilized egg; it enters a 2-week period of rapid cell division and develops into an embryo.
Zygotes
The developing human organism from about 2 weeks after fertilization through the second month (8 weeks)
Embryo
The developing human organism from 9 weeks after conception to birth
Fetus
Agents, such as chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause harm.
Teratogens
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.
Fetal Alcohol Syndrome
Decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a stimulus, their interest wanes and they look away sooner.
Habituation
Biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience.
Maturation
An optimal period in the life of an organism when exposure to certain stimuli or experiences produces normal development.
Critical Period
All the mental activities associated with thinking, knowing, remembering, and communicating.
Cognition
A concept of framework that organizes and interprets information.
Schemas
Interpreting our new experiences in terms of our existing schemas
Assimilation
Adapting our current schemas (understanding) to incorporate new information
Accomodation
In Piaget’s theory, the stage from birth to nearly 2 years at which infants know the works mostly in terms of their sensory impressions and motor activities. Milestones include object permanence and stranger anxiety.
Sensorimotor Stage
The awareness that things continue to exist even when not perceived, develops during the sensorimotor stage.
Object Permanence
In Piaget’s theory, the stage from about 2 to 6 or 7 years at which a child learns to use language but does not yet comprehend the mental operations of concrete logic. Milestones include pretend play and egocentrism.
Pre-operational Stage
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.
Conservation
In Piaget’s theory, the preoperational child’s difficulty taking another’s point of view
Egocentrism
In Piaget’s theory, the stage of cognitive development from about 7 to 11 years of age at which children gain the mental operations that enable them to think logically about concrete events. Milestones include conservation and mathematical transformations.
Concrete Operational Stage
In Piaget’s theory, the stage of cognitive development (normally beginning about age 12) at which people begin to think logically about abstract concepts. Milestones include abstract logic and the potential for mature moral reasoning.
Formal Operational Stage
