Chapter 7 Flashcards
(14 cards)
Biological motion
The ability to detect whether a stimulus is animate or not from movement cues alone
Structural descriptions
A memory representation of the three-dimensional structure of objects
Apperceptive agnosia
A failure to understand the meaning of objects due to a deficit at the level of object perception
Associative agnosia
A failure to understand the meaning of objects due to a deficit at the level of semantic memory
Figure–ground segregation
The process of segmenting a visual display into objects versus background surfaces
Integrative agnosia
A failure to integrate parts into wholes in visual perception
Object constancy
An understanding that objects remain the same, irrespective of differences in viewing condition
Adaptation (or repetition suppression)
A reduced neural response to a stimulus, or stimulus feature, that is repeated
Category specificity
The notion that the brain represents different categories in different ways (and/or different regions)
Face recognition units (FRUs)
Stored knowledge of the three-dimensional structure of familiar faces
Person identity nodes (PINs)
An abstract description of people that links together perceptual knowledge (e.g. faces) with semantic knowledge
Fusiform face area (FFA)
An area in the inferior temporal lobes that responds more to faces than other visual objects, and is implicated in processing facial identity
Prosopagnosia
Impairments of face processing that do not reflect difficulties in early visual analysis (also used to refer to an inability to recognize previously familiar faces)
Categorical perception
The tendency to perceive ambiguous or hybrid stimuli as either one thing or the other (rather than as both simultaneously or as a blend)
