The size-speed illusion may be due to observer’s eye movements. Manipulation of eye movements has been effective in reducing this illusion. We tested observers perceived speed of vehicles (trains and cars), while requiring them to fixate on a static object (square) in the foreground. Placing the fixation square around the front region of the moving train reduced the size-speed illusion. However the illusion persisted when the square was placed around the train’s visual centroid region. Our findings are robust and we suggest that interventions based on this strategy should be designed and tested in future studies.
