Effects of a Seen Hand on Visuo-Haptic Motion Processing
It has been shown that adaptation to tactile motion across the observer's hand induces a visual motion aftereffect (MAE). This crossmodal aftereffect supports the view that MAEs originate from adaptation in neural substrates underlying multisensory integration, challenging the conventional view...

It has been shown that adaptation to tactile motion across the observer's hand induces a visual motion aftereffect (MAE). This crossmodal aftereffect supports the view that MAEs originate from adaptation in neural substrates underlying multisensory integration, challenging the conventional view that MAEs reflect modality-specific processing in early cortical areas. However, it is not clear how information about a seen hand influences visuo-haptic motion processing. We measured the strength of the visual MAE after visuo-haptic adaptation to the rotation of a radial grating presented with a realistic virtual hand. During the adaptation period, observers moved the arm of a force-feedback device with the right hand, and the grating and the virtual hand moved in synchrony with the observer's hand movements. We found that, after adaptation to visuo-haptic movements, the visual MAE was enhanced when the orientation of the virtual hand was aligned with the unseen observer's own hand. Our results suggest the presence of a visual motion system that is sensitive to both to visual and haptic information about one's own hand. |
