2. What is visual agnosia?

  • A deficit in visual recognition in the absence of deficits in sensory functions (e.g vision), can be modality-specific
  • A deficit in unfamiliar visual recognition in the absence of deficits in sensory functions (e.g vision), can be modality-specific
  • Objects are not recognised because patients no longer know what they are
  • The names of objects cannot be recognised although the object itself can be recognised and used normally

3. What did Newcombe's (1987) double dissassociation finding show?

  • Pps with right parietal lobe lesions could not perform either the spatial or object recognition tasks, whereas the pps with right temporal lobe lesions could
  • Pps with right parietal lobe lesions performed poorly on spatial tasks (maze) and well on face/object recognition, whereas pps with right temporal lobe lesions performed opposite
  • Pps with right temporal lobe lesions performed poorly on spatial tasks (maze) and well on face/object recognition, whereas pps with right parietal lobe lesions performed opposite
  • Neither groups of lesioned pps could perform at control level on both face/object recognition and spatial (maze) tasks

4. 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 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
  • 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

5. 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
