Abstract
The stage at which processing of tactile distance occurs is still debated. We addressed this issue by implementing a new adaptation-aftereffect paradigm with passive touch. We demonstrated the presence of a strong aftereffect, induced by the simultaneous presentation of pairs of tactile stimuli. After adaptation to two different distances, one on each hand, participants systematically perceived a subsequent stimulus delivered to the hand adapted to the smaller distance as being larger. We further investigated the nature of the aftereffects, demonstrating that they are orientation and skin-region specific, occur even when just one hand is adapted, do not transfer either contralaterally or across palm and dorsum, and are defined in a skin-centred, rather than an external, reference frame. These characteristics of tactile distance aftereffects are similar to those of low-level visual aftereffects, supporting the idea that distance perception arises at early stages of tactile processing.
