Figure 1.

Contrasting performance of patients with viewer-centered and stimulus-centered neglect on the gap-detection test [24] (in this task the patient is asked to circle all the complete circles and put an X over circles that have a gap on the left or right side). (a) Performance by a patient with a right frontoparietal stroke and viewer-centered neglect on the gap-detection test. Note that he misses all of the stimuli on the left side of the view but detects left gaps in circles on the right view. (b) Performance by a patient with a right temporal stroke and stimulus-centered neglect on the gap-detection test. Note that he fails to detect the left gaps in circles on the right and left sides of the view.
