The rubber hand illusion is a perceptual illusion in which participants experience an inanimate rubber hand as their own when they observe this model hand being stroked in synchrony with strokes applied to the person’s real hand, which is hidden. Earlier studies have focused on the factors that determine the elicitation of this illusion, the relative contribution of vision, touch and other sensory modalities involved and the best ways to quantify this perceptual phenomenon. Questionnaires serve to assess the subjective feeling of ownership, whereas proprioceptive drift is a measure of the recalibration of hand position sense towards the rubber hand when the illusion is induced. Proprioceptive drift has been widely used and thought of as an objective measure of the illusion, although the relationship between this measure and the subjective illusion is not fully understood. Here, we examined how long the illusion is maintained after the synchronous visuotactile stimulation stops with the specific aim of clarifying the temporal relationship in the reduction of both subjective ownership and proprioceptive drift. Our results show that both the feeling of ownership and proprioceptive drift are sustained for tens of seconds after visuotactile stroking has ceased. Furthermore, our results indicate that the reduction of proprioceptive drift and the feeling of ownership follow similar time courses in their reduction, suggesting that the two phenomena are temporally correlated. Collectively, these findings help us better understand the relationships of multisensory stimulation, subjective ownership, and proprioceptive drift in the rubber hand illusion.

橡胶手错觉是一种感知错觉，当参与者观察到这个模型手与应用于隐藏的人的真实手的笔划同步时，他们会体验到一个没有生命的橡胶手作为他们自己的手。早期的研究集中在决定引发这种错觉的因素、视觉、触觉和其他相关感官模式的相对贡献以及量化这种感知现象的最佳方法上。问卷用于评估所有权的主观感觉，而本体感觉漂移是在诱发错觉时测量手位置感对橡胶手的重新校准的量度。本体感觉漂移已被广泛使用，并被认为是对错觉的客观测量，尽管这一措施与主观错觉之间的关系尚不完全清楚。在这里，我们检查了在同步视觉触觉刺激停止后幻觉保持多长时间，具体目的是澄清减少主观所有权和本体感受漂移的时间关系。我们的研究结果表明，在视觉触觉抚摸停止后，所有权感和本体感受漂移都会持续数十秒。此外，我们的结果表明，本体感觉漂移的减少和所有权感的减少遵循相似的时间过程，这表明这两种现象在时间上是相关的。总的来说，这些发现有助于我们更好地理解多感官刺激、主观所有权、
