The effects of target fixation on induced visual motion were examined in two experiments. In Exp. 1, induced motion was generated by a moving frame, and fixation was disrupted by temporarily extinguishing the target and by requiring subjects temporarily to look at a distractor. Relative to a continuous fixation control, both manipulations increased the perceived latency of induced motion. These effects were confirmed and extended in Exp. 2. Results indicate that target fixation should be carefully controlled in research on induced motion.
