Abstract
Although much research has been done on the role of hysteresis in apparent motion displays, no research has investigated the effects of hysteresis for rotary motion. The present experiment sought to determine and quantify the effects of hysteresis on the rotation percept. Participants viewed two types of apparent motion stimuli, which consisted of tokens appearing to move in a clockwise, counterclockwise, or chaotic fashion. One of the displays slowly changed from favoring a percept of rotation to a percept of non-rotation and vice versa. We fit the data using a logistic function and compared the point at which the direction of motion appeared to switch between chaos and rotation. Our research suggests that hysteresis only had a significant effect on type of motion perceived when the stimulus was moving from “chaos” to rotation. Based on these findings, we conclude that our visual system does not contain low-level motion receptors coded for rotary motion and thus, the percept of rotation is not subject to hysteresis.
