大脑两半球对McCollough效应敏感性的比较研究

THE COMPARATIVE STUDY OF THE SENSITIVITY OF McCOLLOUGH EFFECT ON BOTH CEREBRAL HEMISPHERES

本实验通过对大脑两半球对McCollough效应敏感性的比较研究,探索了心理科学的最新发展之一——大脑两半球不对称性研究的新途径。 实验以正常右利手人为被试。采用单侧视野呈现技术,在控制眼动的情况下,探索了大脑两半球在McCollough效应形成过程中的差异问题及有关问题,并取得了较为可靠的实验材料。实验结果表明:1.大脑两半球对McCollo-ugh效应的敏感性是不同的,大脑右半球对McCollough效应的敏感性高于左半球。2.在双眼适应与单眼适应条件下的比较,被试两侧视野所见的McColl-ough效应彩度值的差值有显著差异。3.男性被试两侧视野所见的McCollou-gh效应彩度值的差值略高于女性被试。4.在同等条件下,女性被试较之于男性被试容易产生更大的McCollough效应。

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
