The hypothesis that the left and right hemispheres of the human cerebral cortex differ in their psychological functions. For most people (most right-handed people and some left-handers) the left hemisphere is dominant for language functions and the right hemisphere is dominant for visual-spatial tasks and nonverbal communication. The right hemisphere processes the left visual field and tends to produce an attentional bias to the left (though reading direction also plays a part in this). Males tend to have more lateralized, less coordinated, brain functions than females, leading some to suggest that this may help to account for greater nonverbal sensitivity among females.
