AP Psychology: Topic 3.4 - Cognitive Development Across the Lifespan

Schema

a concept or framework that helps organiz and interpret information

Assimilation

interpreting new experiences according to existing schemas and adapting them into one's collection of schemas

Accommodation

when new information causes a person to modify their current understandings (schemas)

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

Preoperational stage

in Piaget's theory, the stage (from about 2 to 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

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

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

Object permanence

the understanding that objects continue to exist even when out of view

Mental symbols

mental concepts that represent real objects

Pretend play

make-believe activities in which children create new symbolic relations, acting as if they were in a situation different from their actual one

Conservation

a principle of concrete operational reasoning that properties such as mass, volume, and number remain the same despite changes in form

Reversibility

the understanding that some things that have been changed can be returned to their original state (e.g., water → to ice → to water)

Animism

the belief that objects have lifelike qualities and are therefore capable of having feelings, intentions and emotions

Egocentrism

a characteristic of the preoperational stage in which a child has difficulty taking another person's point of view

Systematic thinking

approaching problems in a rational, step-by-step, and analytical fashion

Abstract thinking

thinking in terms of symbols, ideas, and concepts

Hypothetical thinking

thinking that is based on what is possible and not just what is real even when this conflicts with what is accepted as true

Scaffolding

support structures used by teachers that help a learner get to the next level (breaking down new information or skills into pieces that are digestible for a learner)

Zone of proximal development

the difference between what a learner can do without help and what they can do with guidance and encouragement from a skilled coach or partner

Crystallized intelligence

a person's general knowledge, vocabulary, and reasoning based on acquired information

Fluid intelligence

reasoning ability and the use of new information for learning and problem solving

Dementia

a slowly progressive decline in cognitive function, including memory, thinking, and judgment, that is often accompanied by personality changes
