Sex-related differences in hemispheric asymmetries in processing simple geomerical figures

16 (8 men, 8 women) subjects were required to respond same or different to pairs of geometrical figures. Same responses were given to physical identity pairs, to analog identity pairs, and to name identity pairs. Male subjects showed a left visual-field advantage regardless of the level of processing, whereas female subjects did not show a clear-cut hemispheric asymmetry. These results were discussed in terms of different processing strategies employed by the two sexes.
