Alpha hemispheric asymmetry of males and females on verbal and non-verbal tasks: some preliminary results.

The present study gathered preliminary data from males and females for verbal and non-verbal tasks to explore differences in alpha hemispheric asymmetry. Results indicated a significant task by hemispheric interaction effect which revealed significantly less alpha for the left hemisphere, as compared to the right hemisphere, for the verbal task. Significantly less alpha was found for the right hemisphere during the non-verbal task as compared to the right hemisphere on the verbal task. While significant differences between males and females were not revealed, task, subject, and stimuli differences are discussed as variables which may contribute to results obtained from hemispheric processing research.
