cognitive science
|
study of relationships among cognitive psych, biology, etc.
|
|
structuralism
|
describes elemental components of consciousness , sensations, images, and feelings
based on method of introspection |
|
functionalism
|
addresses what the mind is for instead of its components
|
|
cognitive psychology
|
study of human mental processes and their role in thinking, feeling, and behaving
|
|
mental representation
|
unobservable internal code for information; provide the basis for all cognitive abilities
|
|
stages of processing
|
steps required to form, modify, and use mental representations
|
|
serial processing
|
cognitive operations occur one at a time
|
|
parallel processing
|
cognitive operations occur simultaneously
|
|
cognitive architecture
|
organization of the information-processing components and systems
|
|
architectural distinction
|
distinction between working memory system and LTM system
|
|
module
|
automatic and fast set of processes
|
|
symbolic model
|
class of cognitive architecture that assumes mental representations are symbols that are serially processed by a set of rules
|
|
connectionist model
|
class of cognitive architecture that assumes mental representations are distributed and massively connected and simultaneously processed
|
|
sensory memory
|
very brief storage of visual or auditory information
|
|
self-knowledge
|
capacity to represent the self mentally
|
|
informational access
|
capacity to be able to report on mental representations and their processes
|
|
sentience
|
basic capacity for raw sensations, feelings, or subjective experiences
|
|
reaction time |
number of milliseconds needed to perform a task |
|
proportion of errors |
measure of errors made in a cognitive task |
|
verbal protocols |
tape-recordings of people thinking aloud while carrying out a task provides record of conscious processing |
|
EEG (Electroencephalogram) |
multichannel recording of continuous electrical brain activity detects voltage changes generated by large numbers of neurons |
|
ERP (event-related potential) |
EEG signal reflects brain response to onset of specific stimulus |
|
neuroimaging |
measures the location of neural activation |
|
PET (positron emission tomography) |
uses radioactively labeled water to detect areas of high metabolic brain activity detects increases in blood flow |
|
fMRI (functional magnetic resonance imaging) |
uses magnetic field to reveal detailed images of neuronal tissue and metabolic changes detects changes in oxygen concentration in the blood |
|
method of subtraction |
used to isolate properties of a single stage of cognitive processing assumes SOP used in a simple task aren't modified when a choice is added |
|
double dissociation |
independent variable affects task A but not B a different variable affects task B but not A |
|
default network |
multiple brain regions are active when people are left free to think for themselves without external demands |
