Thinking, Language, and Intelligence 1 Flashcards
thinking
aka cognition
mental activity that goes on in the brain when a person is processing information—organizing it, understanding it, and communicating it to others
includes memory
more than stream of consciousness, also images
mental images
representations that stand in for objects or events and have a picture like quality
used in thought process
kosslyn study
participants look at map of desert island, then start at one place and look for another place
greater physical distance on map between two locations, longer it took participants to scan image for second location
kosslyn second study
ask if frogs have lips and stubby tail, most people visualize frog then rotate image and zoom in
important research thing
tend to engage mental images in our mind much like we engage or interact with physical objects, rotating object in mind takes time not instantaneous
actual image vs mental image brain
actual: info goes from eyes to visual cortex of occipital lobe, processed by other areas of the cortex that compare info to info already in memory
mental: areas of cortex associated with stored knowledge send info to visual cortex, where image is perceived in mind’s eye
PET scans show
areas of visual cortex activated during process of forming image, evidence for role of visual cortex in mental imagery
fMRI scans show
overlap occurs in brain areas activated during visual mental imagery tasks as compared to actual tasks involving visual perception
activity in frontal cortex, temporal lobes, parietal lobes, occipital lobes
frontal cortex, temporal lobe, parietal lobe, occipital lobe, for fMRI card
cognitive control, memory, attention and spatial memory, visual processing
activity for mental vs visual imagery
more activity in visual cortex during perception than in imagery, sensory input activates area more strongly than memory input
areas activated during visual imagery subset of those activated during visual perception
most similarity in frontal and parietal regions rather than temporal and occipital regions
overlap
not in temporal and occipital regions (memory and vision functions) but more overlap in visual nature of tasks
concepts
ideas that represent a class or category of objects, events, or activities
use concepts to think about objects or events without having to think about all the specific examples of the category
tool in problem solving
concepts can also
contain identification of new objects
formal concepts
rigid/strict definitions
concepts defined by specific rules or features
math full of these, ex square
concept must fit very specific features to be considered true example
natural concept
fuzzy concepts that people form not as a result of a strict set of rules, but rather as the result of experiences with these concepts in the real world
important in helping people understand their surroundings in a less structured manner than school-taught formal concepts, form basis for interpreting those surroundings and the events that may occur in everyday life
prototype
concept that closely matches the defining characteristics of the concept
ex apple for fruit
different prototypes for different exposure, experiences, cultures, places
how do prototypes affect thinking
people look at potential examples of a concept and and compare them to the prototype to see how well they match
how identify objects
combination of cognitive processes including concepts, prototypes, and mental images
