Takashima (2008) proposed the sumi painting effect in the Japanese Journal of Psychology. <November 26, 2008>

(A) Watercolor illusion (Pinna, Brelstaff and Spillmann, 2001). Although the whole area except waving borders is homogeneously white, the corridor part appears to be tinted green in the upper panel while the outer and inner parts appear to be tinted so in the lower panel. (B) Achromatic watercolor illusion. Although the whole area except waving borders is homogeneously white, the corridor part appears to be tinted gray in the upper panel while the outer and inner parts appear to be tinted so in the lower panel (Noguchi, Kitaoka and Takashima, 2008). (C) Sumi painting effect. Although the whole area except waving borders is homogeneously gray, the corridor part appears to be tinted lighter in the upper panel while the outer and inner parts appear to be tinted so in the lower pane (Takashima, 2008). These figures are drawn by Akiyoshi Kitaoka.

Do babies see color illusion? This question was examined using the illusion as shown left (see Color illusion 1) (Okumura, Kanazawa and Yamaguchi, 2007). The result demonstrates that seven-month-old infants see this illusion. On the other hand, five-month-old babies showed positive evidence in Experiment 1 but not in Experiment 2. <September 25, 2008>
