It is generally believed that, when information from different sensory modalities is in conflict, vision typically dominates touch. In contrast, it has been shown that haptics can play an important role in the development of visual spatial perception in congenitally blind or early blinded people with restored sight. In the present study, the relationship between touch and vision was investigated by examining the effects of haptics on the appearance of the Hering and Wundt optical illusions in sighted individuals. Participants judged the apparent curvature of two lines in Hering‐ and Wundt‐type figures, while they actively explored a wooden board that was shaped concave, convex, or parallel. They were asked to choose a comparison figure whose shape matched the apparent curvature of the two test lines. The results revealed that the participants’ responses were biased towards the curvature obtained by actively touching the haptic stimuli.
