Abstract
Evaluated differences in performance between adult males and females with respect to Halstead's Neuropsychological Battery, additional tests employed by Reitan (Trail Making Test, Aphasia Screening Test, Perceptual Examination, dynamometer), and other neuropsychological measures (Seashore Tonal Memory Test, Logical Memory and Visual Reproduction portions of the Wechsler Memory Scale). In evaluating differences, 47 matched pairs of non-neurologic males and females were employed. as well as 47 pairs of neurologic patients. A small number of statistically significant differences were found, all of which favored males. Some of these differences occurred with respect to tasks that have very strong motor components, and these differences were shown to be related to hand size. Others pertained to tasks that have strong visual-spatial components. In general, the differences were less prominent with the neurologic than the non-neurologic samples. The question was raised as to possible over-representation of male-superior components in these tests.
