Abstract

This paper argues that tactile distance is categorically perceived as the human body constitutes a landscape of well-defined contours and segments. Two experiments are conducted in order to investigate the degree to which increased tactile distance reflects categorical perception. Moreover, the study attempts to test two accounts: 1) “categorical account” according to which tactile distance traversing the wrist reflects categorical perception of body parts and 2) “localised acuity account” according to which tactile distance increases while perceiving distance in the vicinity of the wrist. Results have shown that body part categories are constructed from a variety of corresponding modes of information. Categorization can be consolidated because “action provides non-arbitrary boundaries in parallel to the way we segment the body in thought and speech” (260).
