Abstract
Flash suppression is a phenomenon of interocular suppression where a monocular prime is immediately followed by dichoptic rival targets, inducing dominance of the contralateral view. Studies examining flash suppression have shown that a prime with visual features provokes feature-selective suppression. This study employed a prime lacking any features and examined the effects on visibility of the dichoptic targets. The prime (homogeneous grey field; luminance, 3.0 cd/m2) was presented to one eye alone for 1000 ms, followed immediately by dichoptic rival targets (blue vs. red squares) for durations of 10–200 ms. Visible colors were contralateral to the prime for targets < 50 ms, and ipsilateral for those > 50 ms. The results suggest that the net effect of flash suppression might be eye-specific and different from feature-selective suppression.
