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

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

2. 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

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 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

5. What happens to the size of the receptive fields of ventral stream neurons across the stream?

  • Each receptive field is differentially sensitive to specific stimuli
  • The receptive field size increases and responses shift towards more complex features
  • There is no change in receptive field size across the stream
  • The receptive field size decreases and responses shift towards less complex features
