We investigated the contribution of haptic and visual information about object size to both perception and action. Kinematics of the right hand were measured while participants performed grasping actions or manual estimations under the guidance of haptic information from the left hand, binocular visual information, or both haptics and vision. The greatest uncertainty was observed with haptic information alone. Moreover, when visual and haptic sizes were congruent, performance was no different… CONTINUE READING
