Developmental Flashcards
Cognition
The mental processes by which we acquire information and use it
Cross-sectional study
Studying participants across different age ranges simultaneously
What was Piaget first to experimentally study?
Genetic epistemology - intellectual growth
Piaget’s antidote to behaviourism?
Constructivist theory - children are active and construct knowledge of the world - important to have rich environment
Equilibrium - cognitive development
Minds tend to equilibrium - Disequilibria stimulates activity and encourages growth
Schemas
Patterns of thought or action that outline what the world is like
How are schemas developed? (2)
Organisation - existing schemas help build new ones - reflexes become visually-directed
Adaptation - assimilation and accomodation
What is meant by assimilation and adaptation (schemas)?
Interpreting incoming information using existing schemas and modifying existing schemas to account for new experiences
Stage theory of development
Unbypassed stages that represent qualitatively different levels of functioning
What are piaget’s stages of cognitive development?
Sensorimotor (0-2), preoperation (2-6), concrete operational (7-12) and formal operational (12+)
6 substages of sensorimotor stage
Simple reflexes
Primary circular reactions
Secondary circular reactions
Coordination of secondary circular reactions
Tertiary circular reactions
Beginning of representational thought
Substage 1
Reflexes - innate - 0-1 months
Substage 2
Primary circular reactions - repetitive - 1-4 months
Substage 3
Secondary circular reactions - more aware of events beyond their body - 4-8 months
Substage 4
Coordination of secondary circular reactions - truly planned behaviour/problem solving - 8-12 months
Substage 5
Tertiary circular reactions - trial and error exploratory schemas - 12-18 months
Substage 6
Beginning of representational thought - problem solving occurs internally - 18-24 months
Deferred imitation
Ability to reproduce behaviour of someone absent - development of mental imagery
When is object permanence developed?
Throughout the sensorimotor stage - achieved in stage 6
Violation of expectation
Habituation study - look longer at new or unexpected situations - suggests they know how something should behave
Renée Baillargeon - op
Infant’s failure to search for hidden object may stem from inability to perform coordinated actions - instead searched for cues that a child understood solidity principle
A not B explainations
Memory, control of action (immature frontal cortex - motor planning), previous behaviour
How do babies aquire knowledge?
Piaget - constructivist
Spelke & Wynn - nativist - innate principles
What is the preoperational stage characterised by?
Development of internalised representations - imitation, pretend play and imagery
Egocentrism
Centration
Reversibility
