1) A) In what way might the dissociations between the ‘what’ pathway and the ‘where-action’ pathway influence a clinician’s approach to rehabilitation? B) Comment on one proposed reason for the conflict between early (physical) and late (semantic) filtering theories of attention. C) The term ‘selective attention’ is used in the attention literature. What does this term mean considering past theoretical evidence?

2) A) Is it reasonable to assess a patient with a disorder of accurately directing movement by asking the patient to judge the position of a black dot, using a multiple choice test in which the person has to judge which picture represents the position of the spot? B) Describe two mechanisms of depth perception. C) What kinds of tests might differentiate types of topographical disorientation? Could the differentiation between the ‘what’ and ‘where-action’ pathway influence an approach to rehabilitation?

3) A) The most common complaint for healthy and brain-damaged persons is that they can recognise the face but forget the name. What are some possible reasons for this? B) While evolution is clearly important in modifying brain mechanism some functions are placed in brain areas that allow connections to other functionally similar or related areas. Discuss in relationship to recognition of expression, emotion and movement.

4) A) Persons with form agnosia find it easier to recognise a line drawing of an object than a silhouette, while this is not the case for the integrative agnosic. Give a possible explanation for the differences between these two perceptual disorders. B) The more information you know about a person, the more likely it is that you will remember their name. Explain why this might be the case in terms of Bruce and Young’s model. How would you change the model to make this prediction more likely?
