Behavioral consequences of brain damage associated with homonymous visual field defects.

Abstract

Nonbrain-damaged Ss performed better than either brain-damaged Ss with homonymous field defects, or brain-damaged Ss without field defects on a group of Halstead's tests and the Trail Making Test. Ss with left field defects were inferior to those with right field defects on several measures, although brain-damaged Ss without field defects were not superior to both groups with field defects on any of the measures. It is concluded that constriction of fields did not impair performance, but that some of the tests are more dependent upon the right hemisphere than upon the left hemisphere.
