Abstract

When two lights were presented in a dark room and one light made to move while the other was stationary, it was found that: One light was perceived as more mobile than the other when it was smaller or fixated. One light was increasingly more mobile when it was smaller and the speed was decreased, or when it was smaller and the difference in size increased, or when it was fixated and the speed decreased, or when it was both a fixated light and a small light. There was no change in relative mobility of one light when it was fixated and there was an increase or decrease of difference in size, or when it was fixated and fixation was varied to the right or to the left, or when the light was a right light or a left light.
