- What was Berhamann and Colleagues study?
- Task to study objects and their parts:
Row A: study
Row B: change in parts
Row C: Change among relation of original parts
- How did pt SM perform on Berhamann and colleagues study?
- SM: can do part change but could not tell the change among the relation of parts
- What did pt SM show about integrative agnosia?
- Can be domain specific: inability to encode the relation among parts - tell the diff among parts
- What could pt CK do?
- could recognize faces but nothing else - could not tell the parts/ objects that made up a face - spared face processing
- impaired face processing, impairment recognizing faces, can recognize person non visuall, person memory intact, only deficit may be fae processing
- what is the typical lesion for prosopagnosia?
- bilateral ventral path lesions
- Double dissociation: CK and prosopganosia?
- CK: only recognize faces
prosopagnosia: cannot recognize faces but other objects
- fusiform face area - part of the fusiform face gyrus
- Arguement that FFA is learned (experince):
- FFA is a region that can be recruited for anything that person becomes an expert at making fine discrimination w/
- Arguement that FFA is innate (natural)
- born w/ an FFA that becomes more finely tuned for faces as we develop
- What did the Greeble study show about the FFA?
- People who were experts at greebles had the FFA light up, but novices did not suggesting that FFA may be for expertise/fine distinctions
- Greeble study suggests that prosopagnosia may have problems ___ something there were ___ experts at (farmer and sheep)
- recognizing once
- What is the PPA:
- parahippocampal place area
- What is the PPA used of?
- percieving environment, scenes, buildings, and landmarks, in the ventral stream
- What does damage to the PPA lead to?
- inability to learn/recognize new places/poor recognition of landmarks
- 4 brain areas involved in visual recognition:
- 1. FFA
2. Loc: lateral occipital complex
3. body area
- lateral occipital complex: recognize diff kinds of objects living and man made
- 3 ventral stream major concepts:
- 1. object processing occurs in a series of stages
2. visual agnosia can be explained by damage at diff stages in object recog
3. domain specific recognition processors can operate indept and become impaired by damage
