Cutaneous and Kinaesthetic Perception of Traversed Distance

Abstract

Discrimination thresholds for tactually perceived traversed distance were measured in three conditions: cutaneous-only, kinaestheticonly and combined information. The results were 25 mm (32 %) in the first and 11 mm (14 %) in the latter two conditions. Although cutaneous length perception was shown to be possible, perception in the combined condition was found to be mainly based on kinaesthetic information. The maximum-likelihood estimation model of cue combination was not supported.
