3 Flashcards
Mental imagery
Visualization on information including other senses and things you haven’t experienced
Imageless thought debate
Does thought exist independent of imagery
Conceptual peg hypothesis
Pavio
Boat hat vs truth justice
Imagery creates ability to hang on info
Mental scanning
Create mental images then scan in mind
Treat images like we treat physical things
Kosslyn
Spatial representation
Accompanies real mechanism
Epiphenomenon
Propositional representation
Abstract symbols can represent relationships
Equations
Statement
Depective representation
Realistic pictures
Tacit knowledge
Individuals use real world knowledge to unconsciously affect behavior
Size in visual field if spatial, representation should be very similar to how we look
Real things
Mental walk task
Asked to imagine walking and see how far away until animal overflows visual field
Imagery neurons
Respond to specific items when seeing and imagining
Transcranial magnetic stimulation
Decreases brain activity in a specific located area
Behavior disrupted
Kosslyn
Tms visual cortex
Slowed perception and visualation
Removing part of visual cortex decreases
Image size
Unilateral neglect
Patient ignores objects in 1/2 of visual field
Damage to parietal lobes
Imagery and perception are separate but may have same mechanisms
Perception: automatic, bottom up
Imagery: effortful, top down
Method of loci
Things placed in spatial layout to help remember
Pegword technique
Associating items with words
Mental stimulation
Operation mentally represented/imagines
Rule based approach
Applies rule
Language
System of communicating using sounds or symbols
All humans have language
Developmental trajectory similar for all cultures
Skinner
Language learned through reinforcements
Chomsky
Language is innate, children produce sentences they have never heard before
Psycholinguistics
Psychological study of how humans acquire and process language
Lexicon
All words a person knows
Phoneme
Shortest segments of speech that if changed changes meaning of word
Morpheme
Smallest part of speech that has meaning
Truck vs bedroom
S
Ed
Phonemic restoration effect
Perceptual system fills in for missing phonemes based on context
Top down
Speech segmentation
Using individual words
Statistical learning
Higher likelihood that certain phoneme follows others to make valid word
Word superiority effect
Letters are recognized faster when in a word than when alone
Word frequency effect
More common words recognized and understood faster
Lexical ambiguity
Words can have multiple meanings usually resolved through context, some evidence shows multiple meanings active until resolved through context
Meaning dominances : biased vs balanced
Understanding sentences
Words not often alone
Combinations to provide more complex communication
Semantics: meaning
Syntax: rules
Brock’s aphasia
Can’t produce
Slow labored speech
Wrinkles aphasia
Fluid but makes no sense
