AP Chapter 5 Flashcards
Developmental Psychology
A branch of psychology that studies physical, cognitive, and social change throughout a 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 two week after fertilization through the second month.
Fetus
The developing human organism from 9 weeks after conception to birth.
Teratogens
(Literally,”monster maker”) agents as chemical and viruses that can reach he embryo or fetus during prenatal development and cause harm.
Fetal Alcohol Syndrome (FAS)
Physical and cognitive abnormalities in children caused by a pregnant women’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 behaviour, relatively uninfluenced by experience.
Cognition
All mental activities associated with thinking, knowing, remembering, and communicating.
Schema
A concept or framework that organizes and interprets information.
Assimilation
Interpreting out new experiences in terms of our existing schemas.
Accommodation
Adapting our current understanding (schema) to incorporate new information.
Sensorimotor Stage
In Piaget’s theory, the stage (birth - 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.
Egocentrism
In Piaget’s theory, the preoperational child’s difficulty of taking another’s viewpoint.
Preoperational Stage
In Piaget’s theory, the stage (from age 2 - age 6 or 7) 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 or concrete operational reasoning) that properties such as mass, volume, and number remain the same despite change in the forms of objects.
Theory of Mind
People’s ideas about their own and other’s mental states - about their feelings, perceptions, thoughts, and the behaviours these might predict.
Concrete Operational Stage
In Piaget’s theory, the stage of cognitive development (ages 6/7 - 11) during which children gain the mental operations that enable them to think logically about concrete events.
Autism
A disorder that appears in childhood and is marked by deficient communication, social interaction, and understanding other’s state 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 early in the life of an organism when exposure to certain stimuli or experiences produce normal development.
Imprinting
The process by which certain animals form attachments during a critical period very early in life.
