Behavioral and ERP results from the spatial and verbal WM test, computed for the entire sample at the median MRT  =  11.40.

<p>Although males were again faster at the spatial task than at the verbal task, there was no significant sex difference in RT in either task. Females were more accurate at the verbal task than males and were more accurate than their own performance at the spatial task. Males had a larger P300 during encoding in the verbal task than in the spatial task.
