4. Cognition Flashcards
Info processing model
thinking requires sensation, encoding and storage of stimuli; brain analyzes stimuli to make decisions; decisions can be adjusted to solve new problems aka situational modification; problem solving is based on cognition and complexity of problem
List and explain 4 stages of Piaget’s cognitive development
1) sensorimotor - 0-2 years. child learns to manipulate environment to meet physical needs; consists of circular rxns. ends w/ object permanence and representational thought
2) preoperational - 2-7 years; symbolic thinking (ability to pretend), egocentrism (inability to imagine another person’s feelings), centration (focusing on one aspect of a situation); may be unable to complete conservation task (ex: can’t tell if same amount of liquid in a tall+skinny beaker vs short+wide beaker)
3) concrete operational - 7-11 years; can think logically only w/ concrete objects and info; can complete conservation task (ex: can tell if same amount of liquid in a tall+skinny beaker vs short+wide beaker)
4) formal operational - 11 yrs+; can think logically about abstract ideas and problem solving; can process complex emotions; can do algebraic operations
primary vs secondary circular rxns
repetition of movement occuring by chance (ex: sucking thumb) vs manipulation outside of body (ex: throwing toys)
object permanence vs representational thought
child understands that objects exists not in view vs child creates mental representations of external objects
Piaget’s adaptation of schema (ie. methods to process modify schemas): assimilation vs accommodation
incorporating new info to existing info vs modifying existing info to understand new info
Describe the timeline of language acquisition. Language acquisition device
9-12 mo: babbling 12-18 mo: 1 word/mo 18-20 mo: explosion of random words 2-3 years: 3 word sentences 5 years+: master hypothesized pathway that aids children in ascertaining the rules of a language during their early development; active during childhood, and lost during adulthood
Lev Vgotsky
cognitive development = based on culture
fluid intelligence vs crystallized intelligence
solve problems w/ speed and insight, w/ problem solving and critical thinking; peaks thru early adult yrs to old age vs solve problems w/ learned skills, concrete facts, acquired knowledge; peaks at elderly yrs
Concordance rates
likelihood of twins developing same traits
rooting reflex vs Moro reflex vs Babinski reflex vs grasping reflex
anything touching cheek –> head turns vs any head movements –> arms fan out vs anything touching sole –> toes fan out vs holding something in hands
What’s parallel play?
children playing together w/o influencing e/o
Representative vs availability heuristic
categorizing items based on their stereotypical or prototypical categories vs how likely something is, use info that’s readily available
anchoring bias
using initial piece of info to make subsequent judgments
essentialism
object’s characteristics make up what they are
Aphasia. Broca’s vs Wernicke’s vs conduction aphasia vs anomia vs agraphia
Deficit in language production or comprehension. Loss in word production, aka expressive aphasia or non-fluent aphasia vs loss in word comprehension, aka receptive aphasia or sensory aphasia vs arcuate fasciculus is affected —> word production and comprehension is fine but they can’t repeat what they said vs inability to name objects vs inability to write
