Abstract

Psychophysical studies reveal distortions in perception of distance and shape. Are reaches calibrated to eliminate distortions? Participants reached to the front side. or back of a target sphere. In Experiment 1, feedforwardreaches yielded distortions and outward drift. In Experiment 2, haptic feedback corrected distortions and instability. In Experiment 3, feedforward caches with only haptic experience of targets replicated the shape distortions but drifted inward. This showed that outward drift in Experiment 1 was visually driven. In Experiment 4, visually guided reaches were accurate whenparticipants used binocular vision but when they used monocular vision, reaches were distorted. Haptic feedback corrected inaccuracy and instability of distance but did not correct monocular shape distortions. Dynamic binocular vision is representative and accurate and merits further study.
