Abstract

According to the predictive coding account, the attenuation of tactile perception on the hand exposed to the visuo-tactile Rubber Hand Illusion (vtRHI) relies on a weight increase of visual information deriving from the fake hand and a weight decrease of tactile information deriving from the individual’s hand. To explore if this diametrical modulation persists in the absence of vision when adopting the somatic RHI (sRHI), we recorded tactile acuity measures before and after both RHI paradigms in 31 healthy individuals, hypothesizing a weight decrease for somatosensory information deriving from the hand undergoing the illusion and a weight increase for those deriving from the contralateral hand in the sRHI. Our results showed a significant overall decrease in tactile acuity on the hand undergoing the illusion whilst no changes emerged on the contralateral hand during sRHI. Since the sRHI was not accompanied by the hand spatial remapping, despite the generation of the feeling of ownership toward the fake hand, we hypothesized spatial remapping might play a pivotal role in determining sensory information weight attribution.

主人感对触觉的影响:预测编码理论是否适用于体感橡胶手幻觉?
根据预测编码理论,视觉-触觉橡胶手幻觉(vtRHI)中手部触觉感知的衰减依赖于来自假手的视觉信息权重的增加和来自个人手部的触觉信息权重的减少。为了探索在采用体感橡皮手幻觉(sRHI)时,这种对偶调节是否会在没有视觉的情况下持续存在,我们记录了 31 名健康人在两种橡皮手幻觉范式前后的触觉敏锐度测量结果。我们的研究结果表明,发生幻觉的那只手的触觉敏锐度总体上明显下降,而对侧手的触觉敏锐度在 sRHI 期间没有变化。由于sRHI并不伴随手的空间重映射,尽管对假手产生了拥有感,我们推测空间重映射可能在决定感觉信息权重归属方面起着关键作用。

期刊介绍: Consciousness and Cognition: An International Journal provides a forum for a natural-science approach to the issues of consciousness, voluntary control, and self. The journal features empirical research (in the form of regular articles and short reports) and theoretical articles. Integrative theoretical and critical literature reviews, and tutorial reviews are also published. The journal aims to be both scientifically rigorous and open to novel contributions.
