視野と周辺視反応時間の関係について

Abstract

From this study we got the relationship between the visual field and the peripheral visual reaction time (RT) about the fixation target as follows. When we indicate the extensive of the visual field : V°, the stimulus loci : S° 1 In comparison with the same stimulus loci (visual angle) of the fixation target, the smaller the ratio of S°/V°is the faster the RT is. 2 In comparison with the different stimulus loci (visual angle) of the fixation target, where the ratio of S°/V°is same, the RT becomes same. 3 IT comes from the fact that the same brightness stimulus can be percepted as the different brightness according to the difference of the visual field of the fixation target.
