A static figure called “rotating snake” was a kind of “Fraser-Wilcox illusion” (Fraser and Wilcox, 1979) which produced strong illusory motion by the static arrangement of regions in different colors (http://www.ritsumei.ac.jp/~akitaoka/index-j.html). This stimulus was invented by Kitaoka and recently investigated psychophysically (Backus and Oruc 2005, Journal of Vision 5, 1055–1069.) and neurophysiologically (Conway et al.,2005. The Journal of Neuroscience, 25, 5651–5656.). In this study, we use this “rotating snake” as a stimulus and investigated the illusory perception in infants. 41 6- to 8-month-old infants participated in this study. We prepared original “rotating snake” and control stimulus which was very similar in appearance to the original one but did not produce illusory motion. We presented these original and control stimuli side by side in the monitor and measured the infants’ looking time to the original “rotating snake”. In each trial the stimuli were presented 15 seconds and four trials were conducted for each infant. Results of the ratio of looking time showed that infants looked the “rotating snake” significantly longer (58.97 % t(22)=4.21, p<.001). These results suggest that 6- to 8 month-old infants perceive the illusory motion produce by the specific arrangement of four-color regions.
