Abstract

Five experiments were performed to compare the effects of inner and outer segments on the neon color spreading using the modified Redies-Spillmann figure. Experiment 1 examined the effect of collinearity of inner and outer segments on neon color spreading and experiment 2 compared the effect of continuity. Experiment 3-1 and 3-2, investigated the effects of same space and length of colored segments and outer segments on neon color spreading. Experiment 4 tested how the degree of neon color spreading changed when inner and outer segments were added. The result showed that the impact of outer segments was stronger than inner segments on neon color spreading in collineartity and continuity. However, the effects of identical spaces and lengths were less important than collinearity and continuity on color spreading. In contrast with addition of inner segments, when outer segments were added color spreading were reduced significantly. These results suggest that the centrifugal color spreading is stronger than centripetal spreading and that the subjective contours and the color spreading are caused by separate mechanisms.
