Abstract

It is noted that the perceptual experience of body and space can be modulated by changing the action capabilities or by manipulating the perceived body dimensions through a multisensory stimulation. This study adds to pre-existing literature by investigating the alterations in bodily experience following embodiment to both enlarged and shrunked bodies, while participants actively navigated in a virtual environment. A normal-sized body served as a reference condition. After each embodied navigation, participants estimated the height and width of three different body parts. Results revealed that the embodiment over shrunked body induced a significant reduction in participants' body image, while no changes were reported after the embodiment over the enlarged body. Findings were discussed in terms of previous literature exploring the constraints implicated in the ownership over different bodies.

摘要

值得注意的是，身体和空间的感知体验可以通过改变行动能力或通过多感官刺激来操纵所感知的身体维度进行调节。本研究通过调查参与者在虚拟环境中积极导航时，在与放大和缩小的身体融合后身体体验的变化，为先前的文献增添了内容。正常大小的身体作为参照条件。在每次融合导航后，参与者估计三个不同身体部位的高度和宽度。结果显示，与缩小的身体融合会导致参与者身体意象显著降低，而与放大的身体融合后则未报告有变化。根据先前探索与不同身体所有权相关的限制因素的文献对研究结果进行了讨论。
