in physiological psychology, the development of specialized functioning in each hemisphere of the brain or in the side of the body which each controls. The most obvious example of laterality is handedness, the tendency to use one hand or the other to perform activities. It is the usual practice to classify persons as right-handed, left-handed, or ambidextrous (two-handed). People differ considerably in the range of activities for which they prefer a given hand as well as in the degree of disparity in skill between their two hands. Probably no one favours his right or left hand exclusively.
