Infant cognitive development Flashcards
piaget’s theory
sensorimotor, preoperational, concrete, formal
sensorimotor
first stage, 0-2 years, 6 substages
vygotsky’s socialcultural theory
cognitive development occurs when interacting with others
language development stages
intentional vocalization (cooing, vowels), babbling (consonants and vowels), understanding, holophrastic speech, under extensions, first word, vocab growth spurt, telegraphic speech
holophrastic
word expressions when saying first words, “ju” for juice
underextention
a word is only that word for under certain category, “doggy” for just the neighbors dog but not other dogs
first word and cultural differences
nouns in English, verbs in Chinese, influenced by emphasis on object in culture
telegraphic speech
two word sentences, “doggie pretty”
child directed speech
baby talk
theories of language development
Chomsky language acquisition, social pragmatics
chomsky language acquisition
infants equipped with neurological construct of language, universal language
social pragmatics
info, terms, and imitates speech to communicate
two theories of cognitive development
classical and operant conditioning
classical conditioning
learning through association, cs related to ucs to produce cr, ucr stems from ucs from the start
pavlovs study
ucr= salivation, usc= sight of food, cs=bell, cr=salivation after bell
operant conditioning
learning through behavior
shaping
training a behavior
positive reinforcement
adding to encourage (adding alarm to wake up)
negative reinforcement
removing to encourage (turning off alarm to get up)
positive punishment
adding to decrease behavior (scolding child for doing something wrong)
negative punishment
removing to decrease behavior (turning off alarm for it to not be loud)
reinforcers
encourages behavior
punishments
decreases behavior
behaviorism
by watson, little albert experiment where a rat was shown at first not being scared to albert but everytime before showing albert the rat, a loud noise occured, at the end albert was scared of the rat because of the loud noise
social learning theory
actions learned through observation and imitation, bobo doll experiment
long term memory
final stage of memory, infinite capacity, must refer to info when performing task, broken into implicit and explicit
explicit memory
facts, semantic memory (episodic memory)
implicit memory
procedures, how to tie shoe
short term memory storage
short duration to hold info, if info is forgotten after encoding it won’t go into short term memory, capacity is 7 items plus or minus two
long term memory storage
holds semantic infor for long time, needs to be recalled
anterograde amnesia
can’t store new memories
retrograde amnesia
can’t retrieve old memories
