Comparison of verbal IQ, Tactual Performance, Seashore Rhythm and Finger Oscillation Tests in the blind and brain-damaged.

Abstract

Presented a brief clinical report that compared the performance of blind patients (N = 60) with and without neurologic disorder on verbal subtests of the WAIS, Tactual Performance Test, Seashore Rhythm Test and Finger Oscillation Test. Results suggest that the tactual performance test is the most useful neuropsychologic measure in differentiating non-brain-damaged and brain-damaged blind patients. Results also suggest the possibility of limited recovery of right hemisphere functioning in blind, brain-damaged patients because of loss of visual input.
