| Abstract(in English) | In visual processing, lower visual field superiority has been reported in various studies. In the present study, we investigated whether a similar lower visual field advantage is observed in the discrimination threshold of left or right heading direction by optic flow. In Experiment 1, we examined whether the location of the focus of expansion/contraction of the optic flow in the upper or lower visual field caused a difference in the vertical eccentricity conditions. The optic flow stimuli were presented in both the upper and lower visual fields in Experiment 1, but in Experiment 2, we limited the optic flow to the upper or lower visual fields and examined the same direction discrimination thresholds as in Experiment 1. The results showed that the lower visual field was not superior in either experiment, suggesting that there is no clear upper/lower visual field difference in the discrimination sensitivity between the left and right heading directions. |
