Sex and hemispheric differences in the recall of verbal and spatial information.

Arrays of four digits were presented in a 3 X 3 matrix for 80 msec to either the left or right visual field. Women recalled digits presented to the left and right visual fields equally well, while men recalled digits more accurately after presentation to the right visual field. Both men and women recalled the positions of the digits presented to the left and right visual fields equally well. Overall, men's recall of positions was superior to that of women. Handedness correlated only with recall of positions presented to the right visual field, positively for women and negatively for men.
