infant cognitive development Flashcards
constructivist theory of development
children play an active role in learning and development
- child is an active agent in their development unlike operant condition theories where they were passive
schemas
- cognitive representations of the world
- determine how children of different ages organize and understand informations
assimilation
incorporation of new experiences into existing schemas
accomodation
modifying schema to fit new information
stages
- sensorimotor
- peoperational
- concrete
- formal
sensorimotor
- birth to 2 years
- schemas are limited sensory experiences and motor skills
- has 6 substages: reflexes, primary circular reactions, secondary circular reactions, coordination of secondary, tertiary circular reactions and mental representation
object permanence
understanding that an object continues to exist independent of one immediate perceptual experiences
- stages that help object permanence grow, not just one day they dont get it and the next they do
mental representation
the ability to hold and manipulate objects and events in one’s mind
- 18-24 months
- pretend play
- language
challenges to piaget
- underestimated infants cognitive abilities
- neglected in the moment contextual influences
- development is more gradual then his idea
core capacities
innate, mental capacities that are building blocks to cognitive development
nativist
claims that infants are born with core capacities in areas such as number, object properties
- evolutionary history has shaped our understanding
- thought that piaget was focusing too much on motor skills and not cognition
violation of expectation paradigm
compares infants looking at expected or possible events compared to unexpected events
- show babies a possible and impossible event and they look longer at the impossible because they find it suprising
- this shows that they have some understanding
principle of persistence
an innate understanding that objects retain their physical properties (like height)
ex: understand that when tall carrots are behind a shorter box, the leafs should be visible
infant understanding of gravity and support
in the floating box study, infants tended to expect a box to fall as it did not have support
approximate number sense (ANS)
infants ability to estimate the approximate magnitude of items in a set without relying on counting
- develops over first year
- will understand that if they are shown one doll and then that another is being added, they will be surprised to see 3
challenges to nativism
infant looking time patterns may be explained by attention to perceptual features
- dont test babies in the first few days even though they are getting a lot of experience then
developmental systems theory
human behaviour is the product of a complex, ever changing system, and many factores create developmental change
- rejection of the nativist idea of innate, core capacities
modifying a not b task
- performance on any cognitive task is affected by the surrounding context and repeated sensory feedback
- in a not b, repeated reaching intensifies a simple motor habit (perseveration)
recognition memory
recognition that a specific stimulus had been experienced in the past
- infant pays more attention to a new stimulus vs a familiar stimulus
memory and conjugate mobile studies
- infant memory for action on the environment
- a kids leg is tied to a mobile so he kicks his legs, and will kick even when not tied. but if never tied, wont ever kick
deferred imitation tasks
even 6 months old can later recall a sequence of actions
- older infants can recall more complex sequences for longer periods of time
HOME
a gold standard instrument, using a checklist to measure infant home experiences
context of cognitive development
- poverty places infants at risk for later cognitive delays
- interventions for 0-3 y/os and their families living in poverty
example intervention: carolina abcedarian project
poor children between infancy and 5 attended a full time day care with activities focused on cognitive stimulation, language development and social growth and showed sustained academic and cognitive achievements compared to those who didnt get intervention
