1

activation rule

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

2

auditory information store

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

3

caricature

an exaggeration of distinctive feartures to make a pattern more distinctive

4

detection paradigm

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

5

distinctive feature

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

6

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

7

feature theory

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

8

geons

different three dimensional shapes that combine to form three dimensional patterns

9

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

10

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

11

interstimulus interval

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

12

neural network model

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

13

nodes

the format for representing conepts in semantic network

14

parallel distributed processing (PDP)

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

15

parallel processing

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

16

partial-report procedure

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

17

pattern recognition

the stage of perception during which a stimulus is identified

18

perceptual confusion

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

19

rehersal

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

20

scan component

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

21

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

22

serial processing

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

23

structural theory

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

24

tachistoscope

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

25

template

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

26

visual information store (VIS)

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

27

whole-report procedure

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

28

word superiority effect

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
