Deck 9: Visual Object Recognition and Knowledge

Question 1

MVPA of visual processing has revealed that the fusiform face area is implicated in the following:

A)The processing of face information, but not information from other visual categories (e.g., tools, houses, shoes)
B)The processing of face information, and of information from other visual categories (e.g., tools, houses, shoes)
C)The processing of information about many visual categories (e.g., tools, houses, shoes), but not faces

Answer 1

B

Question 2

The rationale behind training subjects to become experts at individuating among "Greeble" stimuli is to demonstrate that:

A)Developing perceptual expertise through training can produce a new Greeble-specific area in ventral temporal cortex
B)Developing perceptual expertise through training has no apparent effect on the functional organization of the ventral temporal cortex
C)Developing perceptual expertise through training results in the FFA now also responding preferentially to Greeble discrimination, as well as to face discrimination

Answer 2

C

Question 3

A patient who could recognize a cat if viewed from straight ahead but not from above would suffer from:

A)Apperceptive agnosia
B)Prosopagnosia
C)Associative agnosia

Answer 3

A

Question 4

Patients with semantic dementia suffer from visual agnosia.

Question 5

Which type of agnosia would affect people's recognition of faces?

A)Apperceptive agnosia
B)Prosopagnosia
C)Associative agnosia

Question 6

What distinguishes apperceptive agnosia from associative agnosia?

Question 7

What are the two main criticisms of cognitive neuropsychology-influenced models?

Question 8

List three categories of visual stimuli that have been used to argue for category specificity in visual processing.

Question 9

Difficulty recognizing faces is a hallmark of what type of visual agnosia?

Question 10

How have "Greebles" challenged the claims about functional specialization of the fusiform face area (FFA)?

Question 11

Box and arrow diagrams and symbolic manipulation of elements are hallmarks of what type of modeling?

Question 12

What properties of parallel distributed processing (PDP) models make them "neurally plausible"?

Question 13

What has stimulation with electrocorticography electrodes demonstrated about the role of the fusiform face area (FFA) in visual processing?

A)FFA may be necessary for normal face perception, but not for word reading
B)FFA does not seem to be necessary for normal face perception, but is for normal word reading
C)FFA may be necessary for normal face perception and for normal word reading
