Pattern Recognition
The stage of perception during which a stimulus is identified
An unanalyzed pattern that is matched against alternative patterns by using the degrees of overlap as a measure of similarity
Problems With Template Theory
1) The comparison requires that the template be in the same position & orientation & be the same size as the pattern you are trying to identify
2) Great variability of patterns
3) A template theory doesn't reveal how 2 patterns differ
4) Doesn't allow for alternative descriptions of a pattern
Feature Theory
Theory of pattern recognition that describes patterns in terms of their parts or features
Structural Theory
Specifies how the features of a pattern are joined to other features of the pattern
(NOT Finished)
Different 3-Dimensional shapes that combine to form 3-D patterns
Partial-Report Procedure
A task in which observers are cued to report only certain items in a display of items
Visual Information Store (VIS)
A sensory store that maintains visual info for approximately 1/4 of a second
Serial Processing
Carrying out 1 operation at a time, such as pronouncing 1 word at a time
Parallel Processing
Carrying out more than 1 operation at a time, such as looking at an art exhibit & making conversation
Word Superiority Effect
The finding that accuracy in recognizing a letter is higher when the letter is in a word than when it appears alone or is in a nonword
Excitatory Connection
A reaction to positive evidence for a concept, as when the presence of a vertical line provides support for the possibility that a letter is a K
Inhibitory Connection
A reaction to negative evidence for a concept, as when the presence of a vertical line provides negative evidence that a letter is a C
Parallel Distributed Processing
When info is simultaneously collected from different sources & combined to reach a decision
Neural Network Model
Theory that uses a neural network as a metaphor in which concepts (nodes) are linked to other concepts through excitatory & inhibitory connections
