PSYC317 CH2-5 Rev. Flashcards
a rule that determines how inhibitory and excitatory connections combine to determine the total activation of a concept
activation rule
In Sperling’s model this store maintains verbal information in short-term memory through rehearsal.
auditory information store
an exaggeration of distinctive feartures to make a pattern more distinctive
caricature
a procedure in which observers have to specify which of two possible target patterns is present in a display
detection paradigm
a feature present in one pattern but absent in another, aiding one’s discrimination of the two patterns
distinctive feature
a positive association between concepts that belong together, as when a vertical line provides support for the possibility that a letter is K
excitatory connection
a theory of pattern recognition that describes patterns in terms of their parts, or features
feature theory
different three dimensional shapes that combine to form three dimensional patterns
geons
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
inhibitory connection
a theory that proposes that both feature knowledge and word knowledge combine to provide information about the identity of letters in a word
interactive activation model
the amount of time between the end of a stimulus and the beginning of another stimulus.
interstimulus interval
a theory in which concepts (nodes) are linked to other concepts through excitatory and inhibitory connections
neural network model
the format for representing conepts in semantic network
nodes
when information is simultaneously collected from different sources and combined to reach a decision
parallel distributed processing (PDP)
carrying out more than one operation ata time, such as looking at an art exhibit and making conversation
parallel processing
a task in which observers are cued to report only certain items in a display of items
partial-report procedure
the stage of perception during which a stimulus is identified
pattern recognition
a measure of the frequency with which two patterns are mistakenly identified as each other
perceptual confusion
repeating verbal information to keep it active in short-term memory or to transfer it into long-term memory
rehersal
the attention component of Sperling’s model that determines what is recognized in the visual informaion store
scan component
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
sensory store
carrying out one operatino at a time, such as pronouncing one word at a time
serial processing
a theory that specifies how the features of a pattern are joinded to other features of the pattern
structural theory
a box that presents visual stimuli at a specified duration and level of illumination
tachistoscope
an unanalyzed pattern that is matched against alternative patterns by using the degrees of overlap as a measure of similarity
template
a sensory store that maintains visual infomration for approximately one-quarter of a second
visual information store (VIS)
a task that requires observers to report everything they see ina display of items.
whole-report procedure
the finding that accuracy in recognizing a letter is higher when the letter isin a owrd than when it appears alone or isn a nonword
word superiority effect
when limited amount of capacity is distributed to various task.
allocation of capacity
a physiological state that influences the distribution of mentally capacity to various tasks.
arousal
a decrease in the perceived loudness of an unattended message.
attenuation
performing mental operations that require very little mental effort.
automatic processing
a theory that attempts to explain how people select information when some information processing stage become overloaded with too much information.
bottleneck theory
a theory that proposes that we have a limited amount of mental effort to distribute across tasks, so there are limitations on the number of tasks we can perfomr at the same time.
capacity theory
investing mental effort in one or mor task.
concentration
the influence of the surrounding context on the recognition of patterns.
contextual effect
an automatic influence where people direct their attention
enduring disposition
the proposition that bottleneck occurs at the pattern recognition stage and that attention determines what information reaches the pattern recognition stage.
filter model
learning that occurs when we do not make a conscious effort to learn
incidental learning
proposal that the bottleneck occurs when information is selected for memory
late-selection model
the pattern recognition stage of Broadbent’s model, which protected by the filter (attention) from becoming overloaded with too much perceptual information.
limited-capacity perceptual channel
