当受试者看向被刺激的身体部位时，对触觉刺激的感知是容易的：这种促进甚至发生在视觉信息不可用的时候，比如在黑暗中定向时。目前尚不清楚这种促进作用是否完全归因于眼睛和头部的这种本体感觉定向，或者身体部位的视觉信息是否也可以促进触摸。据报道，一项将视觉和本体感觉分离的实验首次证明，身体某个部位的视觉与本体感觉定向无关，确实可以影响躯体感觉。
THE perception of tactile stimuli is facilitated when subjects look towards the stimulated body site: this facilitation even takes place when visual information is unavailable, as when orienting in the dark. It is not known whether the facilitation is due entirely to such proprioceptive orienting of eye and head, or whether visual information of the body site can also facilitate touch. An experiment is reported which dissociates vision and proprioception, and demonstrates for the first time that vision of a body part, independent of proprioceptive orienting, can indeed effect somatosensation.
