The effects of luminance and color on vection
When observers view a large visual stimulus that moves uniformly, they often perceive illusory selfmotion (vection). In the present study, we investigated the effects of luminance and color of vectioninducing stimulus on vection. In an experiment, participants viewed moving random dots simulating optical flow during forward locomotion. The dots were presented on a black or white background in one of equiluminant colors, namely white (or gray), red, green, or blue. The participants pressed a key whenever they felt vection. After each trial, they also rated vection magnitude (from 0 to 100). Vection onset latency and duration, calculated from the key press data, and rating showed that, irrespective of the luminance of dots and background, red and blue dots produced stronger vection as compared with that induced by achromatic dots. Vection induced by green dots was weaker as compared with that induced by achromatic dots. When a black background was used, vection was induced more strongly by blue dots than by red dots. When a white background was used, vection was induced more strongly by red dots than by blue dots. These results indicated that the background luminance effects on strength of vection.
