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. 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

3. From Humphrey & Riddoch (1987), what were patient HJAs behavioural abilities?

  • Can copy drawings of objects (feature by feature), can draw from memory + can recognise from other modalities. Cannot recognise pictures even though can describe features, cannot use gestalt grouping principles, cant decide if novel objects are real
  • Can copy drawings of objects, cant draw from memory + cant recognise from other modalities. Can recognise pictures even though cant describe features, can use gestalt grouping principles, can decide if novel objects are real

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

  • 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 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 dorsal visual stream. Could poorly recognise faces. Very poor OR, but could be achieved with feature-by-feature analysis. Could segment/group features

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

  • Both participants performed at chance at the grasping task and correctly in form discrimination
  • 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 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 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
