chap13 Flashcards
what led to the cognitive revolution?
increasing interest in complex mental processes -> interdisciplinary (experiemtnal psyc, lingustics, ai, neuroscience) work post ww2, growing criticism of behaviorism, mind model based on COMPUTER
whats cognitive psychology
explains STRUCTURE & OPERATIONS/func/s of mental processes
3 research approaches from outside psych that influenced cognitive psych
1 communications research & info processing 2 computer model 3 generative linguistics
1 research approach w/in psyh that influenced development of cognitive psych
gestalt
when was communications research & info processing approach (cr&ip)? impactful?
ww2
what guided the cr&ip approach?
information theory
explain information theory
info communicated by sending signal thru sequence of stages
why was weaver’s info sequene model significant?
human perception & memory seen similarly
cognition -> flow of info - dominating cognitive psych today
cr&ip: filter model
1st major theoretical effort at cognitive theory presented in form of flowchart
filter model of attention
computer model approach
compares human intelligence to computer system
newell, shaw & simon computer program that solves logic problems like humans
established field of AI
&
interaction bw computer model & info processing approaches
related computer model to info processing psych
human info processing = sequences of computational processes operating on mental representations
eg: img / goal @ given pt,
plan a,b,c / response
tote - test operatetest exit - work or not, if not then go back to plan for next plan
general linguistics approach: universal grammar
human biologically programmed to learn language, innate mental capacity to generate sentences w unconscious knowloedge of language
impact of generative linguistics approach in behavriorism and cognitive psych?
bad for behaviorism
propelled cognitive psych
gestalt application to higher mental processes challenged behaviorism further: bruner, goodnow, austin
pple learn thru STRATEGIES not just associations
matched w info processing approach
cognitive studies @ havard: bruner & miller
mind similar to computer
cognitive psych makes comeback in previously neglected ideas
pattern recognition, atention
cateogrization
memory
reasoning
decision making
problem solving
language
what does cognition involve
all processes by which sensory input is transfomred, reduced, elaborated, stored, recovered, used even in absence of relevant physical stimuli like hallucinations
growth of ocgnitive psych : pattern recognition: how pple perceive and recognize objects -> 2 stages of recognition
1 describe input object primitively
eg 2 diagonal lines n 1 horizontal line connecting em
2 match primitive description to stored object descriptions in memory to retrieve whatever best matches letter A
ie see smthg as individual parts then holistically in memory
growth in cognitive psych: memory models: multi store model
uses rxn time to identify problems @ diff stages of memory
growth of cognitive psych subfield: new psycholinguistics: collins quillian
semantic knowledge organized in hierarchy
how does collins & quillian semantic hierarchy worl
pp asked simple question bout meaning of word,
the greater the categorical diff bw defintions - the longer it took to answer
memory n language: anderson n bower : intersection of memory n language
network models of memory for linguistics
HAM
whats the ham model
combine info processing w linguistics and AI
how r concepts represented in mind
early models: in terms of language
mental imgs
new directions in relating mental processes to brain structures: connectionist modeling
neuroscience
newer directions: cognitive neuroscience: link mental processes w physical brain structures
what 3 factors contributed to cognitive neuroscience
1 connectionist models
2 new neurological research of role of formation of memories and dual system visual perception (ategorizing brain location w func/)
3 methodological advancements, neuroimging- arouse brain to see where func/ - structures heavily involved w func/s
neuroimging seen as …
new age phrenologists?
consciousness redefined as…
cognition bcc sounds more scientific lol
cognitive revolution consists of cellular explanation of…
consciousness
neuropsychologists interested in…
brain anatomy n structure
cognitive psychologists focus on…
abstract models of mind as info processor
cognitive psychologist + neuropsychologist =
cognitive neuroscience : localizing brain function
