Pre-coincidence brain activity predicts the perceptual outcome of streaming/bouncing motion display

Abstract When two identical visual discs move toward each other on a two-dimensional visual display, they can be perceived as either “streaming through” or “bouncing off” each other after their coincidence. Previous studies have observed a strong bias toward the streaming percept. Additionally, the...
