1

a rule that determines how inhibitory and excitatory connections combine to determine the total activation of a concept

activation rule

2

In Sperling's model this store maintains verbal information in short-term memory through rehearsal.

auditory information store

3

an exaggeration of distinctive feartures to make a pattern more distinctive

caricature

4

a procedure in which observers have to specify which of two possible target patterns is present in a display

detection paradigm

5

a feature present in one pattern but absent in another, aiding one's discrimination of the two patterns

distinctive feature

6

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

7

a theory of pattern recognition that describes patterns in terms of their parts, or features

feature theory

8

different three dimensional shapes that combine to form three dimensional patterns

geons

9

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

10

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

11

the amount of time between the end of a stimulus and the beginning of another stimulus.

interstimulus interval

12

a theory in which concepts (nodes) are linked to other concepts through excitatory and inhibitory connections

neural network model

13

the format for representing conepts in semantic network

nodes

14

when information is simultaneously collected from different sources and combined to reach a decision

parallel distributed processing (PDP)

15

carrying out more than one operation ata time, such as looking at an art exhibit and making conversation

parallel processing

16

a task in which observers are cued to report only certain items in a display of items

partial-report procedure

17

the stage of perception during which a stimulus is identified

pattern recognition

18

a measure of the frequency with which two patterns are mistakenly identified as each other

perceptual confusion

19

repeating verbal information to keep it active in short-term memory or to transfer it into long-term memory

rehersal

20

the attention component of Sperling's model that determines what is recognized in the visual informaion store

scan component

21

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

22

carrying out one operatino at a time, such as pronouncing one word at a time

serial processing

23

a theory that specifies how the features of a pattern are joinded to other features of the pattern

structural theory

24

a box that presents visual stimuli at a specified duration and level of illumination

tachistoscope

25

an unanalyzed pattern that is matched against alternative patterns by using the degrees of overlap as a measure of similarity

template

26

a sensory store that maintains visual infomration for approximately one-quarter of a second

visual information store (VIS)

27

a task that requires observers to report everything they see ina display of items.

whole-report procedure

28

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

29

when limited amount of capacity is distributed to various task.

allocation of capacity

30

a physiological state that influences the distribution of mentally capacity to various tasks.

arousal
