Object Processing

Question 1

Apperceptive

Answer 1

• Right hemisphere posterior lesions
• Low level of agnosia
• L-junction
• Not able to guess what something is

Question 2

Integrative

Answer 2

• right/left hemisphere
• More anterior lesions
• Intermediate levels of agnosia
  (ex: identifying T’s)
  (features are detached)

Question 3

associative

Answer 3

Left hemisphere
More anterior lesions
High level of agnosia
Best type of agnosia to guess what something is

Question 4

Figure Copying Test

Answer 4

Apperceptive → junk drawing
Integrative → able to draw but outline is awkward and not in real shapes
Associative → able to draw it similar

Question 5

CK experiment

Answer 5

Able to copy sentences (not able to read)
His parietal cortex in intact (okay)
Just has an inability to recognize things
Able to produce drawing of guitar and england but not identify them

Question 6

Tanaka & Farah, 1993

Answer 6

Showed subjects specific parts of the face (nose, mouth, eyes) → subject were less accurate to identify specific parts rather than identifying whole faces
Isolated parts lower rate than whole face
Concluded that faces are represented holistically (altogether): parts not represented on their own, only in context of whole face

Question 7

Faces Represented Holistically - View #1

Answer 7

Area of the brain devoted specifically to recognizing faces, so not processed like other objects
Faces are evolutionarily important to primates (social cues)

Question 8

Faces Represented Holistically - View #2

Answer 8

Faces are different from other objects → subordinate level
–> We say “oh, michael jordan” not “oh, a face”
We are all “face experts” → fine distinctions among many faces
Faces are represented holistically just like experts represent their objects of expertise

Question 9

Answer 9

focus on: STIMULUS TYPE
- holds that FFA is aface processing module
- the area is involved selectively recognizing faces, its purpose is to recognize faces
