1. What is apperceptive agnosia?

  • Deficits at a perceptual level. Patients often are better at drawing from memory rather than copying an object's form directly and have preserved colour/brightness perception
  • Deficits at the attribution level, where the percept is given meaning by being linked to previous experience. There is accurate copying from vision, but poor drawing from memory

2. From Humphrey & Riddoch (1987), what were patient HJAs neural deficits?

  • Bilateral damage to dorsal visual stream. Could poorly recognise faces. Very poor OR, but could be achieved with feature-by-feature analysis. Could segment/group features
  • Bilateral damage to ventral visual stream. Achromatopsia. Could not recognise faces. Very poor OR even with feature-by-feature analysis. Could segment/group features
  • Bilateral damage to ventral visual stream. Achromatopsia. Could not recognise faces. Very poor OR, but could be achieved with feature-by-feature analysis. Could not segment/group features
  • Bilateral damage to dorsal visual stream. Could not recognise faces. Very poor OR, but could be achieved with feature-by-feature analysis. Could not segment/group features

3. What is associative/integrative agnosia?

  • Deficits at the attribution level, where the percept is given meaning by being linked to previous experience. There is accurate copying from vision, but poor drawing from memory
  • Deficits at a perceptual level. Patients often are better at drawing from memory rather than copying an object's form directly and have preserved colour/brightness perception

4. What did Kourtzi & Kanwishers fMR adaptation study find specifically for the (bi)lateral occipital cortex?

  • Responses were contrasted to scrambled v.s intact object images. The LOC showed to adapt to the same shape with different occluding contours
  • Responses were contrasted to scrambled v.s intact object images. The LOC showed to adapt to the same shape with the same occluding contours
  • Scrambled objects elicited more of a response than intact objects in the LOC
  • Intact objects elicited more of a response than scrambled objects in the LOC

5. What was the double dissassociation finding from Goodale et al (1994) with patient RV and case DF?

  • Case RV (damage to dorsal) could tell the shape of objects apart but could not correctly grasp them. DF (ventral damage) performed at chance at form discrim but could successfully grasp
  • Case RV (damage to ventral) could tell the shape of objects apart but could not correctly grasp them. DF (dorsal damage) performed at chance at form discrim but could successfully grasp
  • Case DF (damage to dorsal) could tell the shape of objects apart but could not correctly grasp them. RV (ventral damage) performed at chance at form discrim but could successfully grasp
  • Both participants performed at chance at the grasping task and correctly in form discrimination
