In our life, reaching movements in peripheral vision are common. However, there are few studies about motor planning in peripheral vision. The purpose of this study was to examine the effect of visual field on motor planning in central vision and peripheral vision during reaching movements. In this experiment, ten right-handed subjects participated in 240 trials of reaching task. They were instructed to reach the cork cube. The cork cube was randomly placed in four different positions; high or low position in central vision, high or low position in peripheral vision. During the experiment, behavior and electroencephalographic signals were recorded. The finding showed that people can easy to plan movement in central vision rather than in peripheral vision. Moreover, we suggested that the factors which affect the perceived affordance may include not only external environments but also the internal processing that is affected by visual fields.
