Your text describes imagery performance of a patient with unilateral neglect. This patient was asked to imagine himself standing at one end of a familiar plaza and to report the objects he saw. His behavior shows
 
  a. neglect manifests itself in perception only, not in imagery.
  b. neglect occurred in imagery such that some objects in the plaza were never reported.
  c. neglect involved both the left and right sides of the visual field, with an apparently random agnosia ofdifferent components of the fields.
 d. neglect always occurred on the left side of the image, with left side being determined by the direction in which the patient imagined he was positioned.

Question 2

Your text describes the case of M.G.S. who underwent brain surgery as treatment for severe epilepsy. Testing of M.G.S. pre- and post-surgery revealed that the right visual cortex is involved in the
 
  a. size of the field of view.
  b. recognition of objects in the left side of space.
  c. ability to visually recognize objects.
  d. ability to draw objects from memory.

Question 3

Kosslyn's transcranial magnetic stimulation experiment on brain activation that occurs in response to imagery found that the brain activity in the visual cortex
 
  a. is an epiphenomenon.
  b. can be inferred using mental chronometry.
  c. supports the idea that the mechanism responsible for imagery involves propositional representations.
  d. plays a causal role in both perception and imagery.
