本文介绍了第一项研究，最近报道的多式联运知觉错觉称为橡胶手错觉的实验研究介导的条件下。当一个人自己的手被放在视线之外，一只看得见的假手与看不见的手同步地反复抚摸和敲击时，受试者报告说，假手被体验为自己身体的一部分的强烈感觉。在我们的实验中，我们在三种条件下研究了这种错觉：（i）无中介条件，复制原始范例，（ii）虚拟现实（VR）条件，其中假手及其刺激都投射在参与者面前的桌子上，以及（iii）混合现实（MR）条件，其中假手被投射，但其刺激是无中介的。依赖性测量包括自我报告（开放式和基于问卷的）和漂移，即隐藏的手的感觉位置与其实际位置之间的偏移。正如预期的那样，无中介条件产生了最强烈的错觉，正如自我报告和向橡胶手漂移所示。VR条件产生了一个更令人信服的主观错觉比MR条件，虽然没有差异的漂移被发现之间的调解条件。结果进行了讨论的感知机制橡胶手错觉，和错觉的相关性，以了解远程呈现。
This paper presents a first study in which a recently reported intermodal perceptual illusion known as the rubber hand illusion is experimentally investigated under mediated conditions. When one's own hand is placed out of view and a visible fake hand is repeatedly stroked and tapped in synchrony with the unseen hand, subjects report a strong sense in which the fake hand is experienced as part of their own body. In our experiment, we investigated this illusion under three conditions: ( i) unmediated condition, replicating the original paradigm, ( ii) virtual reality ( VR) condition, where both the fake hand and its stimulation were projected on the table in front of the participant, and ( iii) mixed reality ( MR) condition, where the fake hand was projected, but its stimulation was unmediated. Dependent measures included self- report ( open- ended and questionnaire- based) and drift, that is, the offset between the felt position of the hidden hand and its actual position. As expected, the unmediated condition produced the strongest illusion, as indicated both by self-report and drift towards the rubber hand. The VR condition produced a more convincing subjective illusion than the MR condition, although no difference in drift was found between the mediated conditions. Results are discussed in terms of perceptual mechanisms underlying the rubber hand illusion, and the illusion's relevance to understanding telepresence.
