Shrinking the Skin: Motion Results in Compressive Mislocalization of Stimuli Applied 10 s Post-Motion.

ABSTRACT: Localizing touch on the skin requires integration of multiple spatial signals, including reference landmarks and motion cues. It is well known that motion patterns can bias the perceived endpoint of motion. However, it is unknown whether static touch presented post-motion is also distorted. To investigate this, we presented space-changing motion patterns and tested position perception 1 s and 10 s post-motion. We used a brush moving along the forearm at 15 cm s^-1, brushing 4.5 cm skin patches near the elbow and near the wrist, skipping a 10-cm long metal-shielded patch in the middle ('numb spot'). It accelerated to 100 cm s^-1 across the shielded gap in an attempt to create an illusion of continuous motion between the separate brushed areas. After several such deceptiv
