在这项研究中，涉及触摸橡胶手的空间限制进行了调查。当橡胶手放置在六个不同空间位置之一时（距离参与者自己的手水平距离17.5-67.5厘米），参与者对感知错觉的强度进行评级。结果显示，错觉的强度存在显著的非线性关系，当两只手距离最近时，评级最高;距离30厘米后，评级显著下降。引发错觉所需的时间也有类似的趋势。这些结果可能反映了双峰视觉触觉细胞编码周围的手空间的响应特性。(C)2006年爱思唯尔公司All rights reserved.
In this study, the spatial limits of referred touch to a rubber hand were investigated. Participants rated the strength of the perceived illusion when the rubber hand was placed in one of six different spatial positions (at a distance of 17.5-67.5 cm horizontal from the participant's own hand). The results revealed a significant nonlinear relationship in the strength of the illusion, with the strongest ratings given when the two hands were closest; decaying significantly after a distance of 30 cm. The time taken to elicit the illusion followed a similar trend. These results may reflect the response properties of bimodal visuo-tactile cells encoding peripersonal space around the hand.
