title: Is interhemispheric transfer related to handedness and gender?
abstract: Interhemispheric transfer was assessed by five motor, tactile and visual tasks which required the 48 subjects to compare stimuli presented simultaneously on both sides of the body midline. Non-right-handers performed significantly better than consistent right-handers on one motor and one tactile task. Females out-performed males on the visual task and on one tactile task. Better interhemispheric transfer performance by non-right-handers and by females may be related to the reportedly larger corpus callosum regions in these groups and also to the reportedly less strong lateralization of function.
