Many anatomical and brain mapping studies show a higher bilateral symmetry of female brains and a higher asymmetry of male brains so correlations between simple visual and auditory, left- and right-hand reaction times were examined for such sex differences. 20 healthy women and 20 men were tested in two sessions. For women all six response times correlated with each other significantly in Session A, but in Session B there were only two significant interhemispheric correlations. This represented different changes in visual and auditory reaction times between Sessions A and B. Men showed the same pattern in both sessions: a significant correlation between the interhemispheric visual reaction times and one between auditory reaction times. Women showed a total correlation pattern in Session A and an interhemispheric correlation pattern in Session B. This was interpreted as a transition between a holistic information-processing strategy in Session A and an analytic strategy in Session B. Men showed an analytic strategy in both sessions.
