Cognitive Development in Infancy Flashcards
Piaget
theory of cognitive development, unifies biology and experience
adaptation
adjusting to new environmental demands
schemes
actions or mental representations that organize knowledge
assimilation
children use their existing schemes to deal with new info or experiences, like incorporating “bike” and “motorcycle” into the category of “car” heard from a caregiver
accommodation
children adjust their schemes to take new info and experiences into account, like removing “bike” and “motorcycle” from the category of “car”
organization
grouping of isolated behaviors and thoughts into a higher-order system to make sense of the world
disequilibrium
cognitive conflict when counterexamples to existing schemes present themselves, necessitating assimilation or accommodation
equilibrium
mechanism by which children shift from one stage of thought to the next, maintaining balance of understanding through assimilation and accommodation
sensorimotor stage
birth to about 2 years old
substages of sensorimotor stage
1-Simple reflexes-1 month
sensation and action coordinated primarily through
reflexive behaviors such as rooting and sucking
2-First habits & primary circular reactions-1-4 months
infant coordinates sensation & 2 types of schemes
3-Secondary circular reactions-4-8 months
more object-oriented, moves beyond preoccupation with
self, imitates simple actions but only those s/he is
already able to produce
4-coordination of secondary circular reactions-8-12 mo.
hand-eye coordination, actions become more outward
directed, coordinate schemes and intentionality
5-tertiary circular reactions, novelty, and curiosity-12-18
mo.
6-internalization of schemes-18-24 months
ability to use primitive symbols
habit
scheme based on a reflex that has become completely separated from its eliciting stimulus, like sucking even when no bottle is present
circular reaction
repetitive action
primary circular reaction
scheme based on the attempt to reproduce an event that initially occurred by chance
secondary circular reaction
scheme that is not intentional or goal-directed, but is repeated because of consequences, like shaking a rattle because of fascination
coordination of secondary circular reaction
infants coordinate schemes with intentional action, like manipulating a stick in order to bring a desired toy within reach
tertiary circular reactions
schemes in which infant purposely explores new possibilities with objects, continually doing new things to them and exploring the results
primitive symbol
internalized sensory image or word that represents an event, so that the infant can think about concrete events w/out directly acting them out or perceiving them
object permanence
understanding that objects continue to exist even when they cannot be seen, heard, or touched, achieved by the end of the sensorimotor period
the A-not-B error
when a toy is hidden at A and later at B, the child still looks for the toy at location A, not consistent and sensitive to the delay between hidings
core knowledge approach
Spelke, infants are born with domain-specific innate knowledge systems involving space, number sense, object permanence, and language
attention
focusing of mental resources on select info, improving cognitive processing, happens by 4 months old
orienting/investigative process
directing attention to potentially important locations in the environment (where) and recognizing objects and their features (what)
sustained attention
focused attention, new stimuli elicits orienting response followed by sustained attention
habituation
decreased responsiveness to a stimulus after repeated presentations of the stimulus
dishabituation
increase in responsiveness after a change in stimulation
