Abstract:
Differences between the sexes in perception and cognition have been extensively documented and widely accepted as applicable to the majority of humans. Understanding of their aetiology can only be achieved by investigation of both hormonal and social factors. A significant recent advance, supporting the role of hormones, is presented. This study correlated corpus callosum size, sex and handedness. It showed that all females have a significantly larger isthmus (part of the corpus callosum) than consistently right-handed males. The inference is that women tend to use both hemispheres and most males only one. This has important educational and work-deployment implications.
