我们能否根据自我报告的经历来评估一个人感知橡皮手错觉的程度的个体差异？在这项研究中，我们使用 Rasch 型模型开发了这样一种仪器。在我们的概念中，将一个物体（例如，橡胶手）融入一个人的身体形象需要各种感觉运动和认知过程。因此，人们能够满足这些要求的程度决定了人们体验并同时描述幻觉的强度。因此，人们对橡皮手错觉的敏感性的个体差异可以通过检查他们的个人经历报告来确定。所提出的模型被证明是有效的，它能够预测人们的经历的自我报告，并可靠地评估对错觉的易感性的个体差异。关于有效性，我们发现个体易感性和本体感觉漂移之间存在微小但显着的相关性。此外，我们发现异步和敲击而不是抚摸手指会限制幻觉的体验。 (C) 2012 Elsevier B.V. 保留所有权利。
Can we assess individual differences in the extent to which a person perceives the rubber-hand illusion on the basis of self-reported experiences? In this research, we develop such an instrument using Rasch-type models. In our conception, incorporating an object (e.g., a rubber hand) into one's body image requires various sensorimotor and cognitive processes. The extent to which people can meet these requirements thus determines how intensely people experience and, simultaneously, describe the illusion. As a consequence, individual differences in people's susceptibility to the rubber-hand illusion can be determined by inspecting reports of their personal experiences. The proposed model turned out to be functional in its capability to predict self-reports of people's experiences and to reliably assess individual differences in susceptibility to the illusion. Regarding validity, we found a small, but significant, correlation between individual susceptibility and proprioceptive drift. Additionally, we found that asynchrony, and tapping rather than stroking the fingers constrain the experience of the illusion. (C) 2012 Elsevier B.V. All rights reserved.
