Week 4/Ch 7: Flashcards
The ability to detect whether a stimulus is animate or not from movement cues alone
Biological motion
A memory representation of the three-dimensional structure of objects
Structural descriptions
A failure to understand the meaning of objects due to a deficit at the level of object perception
Apperceptive agnosia
A failure to understand the meaning of objects due to a deficit at the level of semantic memory
Associative agnosia
The process of segmenting a visual display into objects versus background surfaces
Figure–ground segregation
A failure to integrate parts into wholes in visual perception
Integrative agnosia
An understanding that objects remain the same, irrespective of differences in viewing condition
Object constancy
A reduced neural response to a stimulus, or stimulus feature, that is repeated
Adaptation (or repetition suppression)
The notion that the brain represents different categories in different ways (and/or different regions)
Category specificity
Stored knowledge of the three-dimensional structure of familiar faces
Face recognition units (FRUs)
An abstract description of people that links together perceptual knowledge (e.g. faces) with semantic knowledge
Person identity nodes (PINs)
An area in the inferior temporal lobes that responds more to faces than other visual objects, and is implicated in processing facial identity
Fusiform face area (FFA)
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)
Prosopagnosia
The tendency to perceive ambiguous or hybrid stimuli as either one thing or the other (rather than as both simultaneously or as a blend)
Categorical perception
