PSYC317CH2 Flashcards
activation rule
a rule that determines how inhibitory and excitatory connections combine to determine the total activation of a concept
auditory information store
In Sperling’s model this store maintains verbal information in short-term memory through rehearsal.
caricature
an exaggeration of distinctive feartures to make a pattern more distinctive
detection paradigm
a procedure in which observers have to specify which of two possible target patterns is present in a display
distinctive feature
a feature present in one pattern but absent in another, aiding one’s discrimination of the two patterns
excitatory connection
a positive association between concepts that belong together, as when a vertical line provides support for the possibility that a letter is K
feature theory
a theory of pattern recognition that describes patterns in terms of their parts, or features
geons
different three dimensional shapes that combine to form three dimensional patterns
inhibitory connection
a negative association between concepts that do not belong together, as when the presence of a vertical line provides negative evidence that a letter is a C
interactive activation model
a theory that proposes that both feature knowledge and word knowledge combine to provide information about the identity of letters in a word
interstimulus interval
the amount of time between the end of a stimulus and the beginning of another stimulus.
neural network model
a theory in which concepts (nodes) are linked to other concepts through excitatory and inhibitory connections
nodes
the format for representing conepts in semantic network
parallel distributed processing (PDP)
when information is simultaneously collected from different sources and combined to reach a decision
parallel processing
carrying out more than one operation ata time, such as looking at an art exhibit and making conversation
partial-report procedure
a task in which observers are cued to report only certain items in a display of items
pattern recognition
the stage of perception during which a stimulus is identified
perceptual confusion
a measure of the frequency with which two patterns are mistakenly identified as each other
rehersal
repeating verbal information to keep it active in short-term memory or to transfer it into long-term memory
scan component
the attention component of Sperling’s model that determines what is recognized in the visual informaion store
sensory store
the part of memory that hold unanalyzed sensory information for a fraction of a second, providing an opportunity for additinoal analysis following the physcial termination of stimulus
serial processing
carrying out one operatino at a time, such as pronouncing one word at a time
structural theory
a theory that specifies how the features of a pattern are joinded to other features of the pattern
tachistoscope
a box that presents visual stimuli at a specified duration and level of illumination
