Abstract: Through the comparative experiment of the sensitivity of McCol-lough effect on both cerebral hemispheres, this study explored oneof the latest developments of psychology——a new way of asy-mmetry of brain function. The experiment used normal right-handed people to serve as sub-jects. The technology used in this experiment was one sided fieldof vision by which the director could control the subjects' eyemovement and find out the difference between both cerebal hemis-pheres in the process of forming McCollough effect and other conn-ected problems. Some reliable materials were obtained. The reaults show that:1. The sesitivity of both cerebral hemispheres to McCollough effect is different. The sensitivity of the right hemisphere is higher than that of the left one(P<0.05).2. The different values of McCollough effect hue of two-side field of vision of the subjects is remarkably different in conditions of two-eye adaptation and one-eye adaptation(p 0.05).3. The different values between left and right visual fields of the male subjects is higher than that of the female subjects with no remarkable difference (0.05 P 0.10).4. Under same conditions, female subjects produce stronger McColl- ?ugh effect more easily than male subjects
