Abstract

Two experiments were conducted to investigate the impact of color, spatial frequency and shape on chromatic induction. In experiment 1, the effects of inducing colors and test colors were examined. Stimuli were S-cone patterns and L-cone patterns of concentric circles. The result of experiment 1 showed that chromatic induction occurred both with S-cone and L-cone patterns. In particular, chromatic induction was strong when inducing colors in the S-cone patterns were purple. Test colors also affected chromatic induction. In experiments 2, the effect of spatial frequency and shape of the stimulus were tested. Three types of shape were used as stimuli; concentric circle like in experiment 1, straight line and arc. The result of experiment 2 showed that, if spatial frequency was higher chromatic induction was strong in all shape of stimuli. These results imply that chromatic induction is concerned with early stage of visual information process.
