Complex partial epileptic-like signs and differential visual search times for normal men and normal women: Implications for functional lateralization

In order to evaluate the construct validity of a subjective experience inventory that has been employed to infer complex partial epileptic-like signs (CPELS), specific tasks such as the Seashore Rhythm. Speech-sounds, Immediate and Delayed Verbal and Figural Memory, Digit Span, Corsi block and Visual Search Tasks, were administered to 50 men and 50 women. The strongest correlation (0.57) occurred between the numbers of CPELS and search times for the upper relative to the lower right visual field for the men but not for the women. The results support the existence of sexual mosaicism and balanced human polymorphism within brain-behavioral correlates. Normative data for the neuropsychological tasks are also presented.
