身体错觉通常使用视觉和/或触觉输入来产生一个人的身体改变大小的生动体验。自然主义听觉输入（反映刺激的自然声音的输入）已被用于增加橡胶手错觉期间的错觉体验，而非自然主义听觉输入可能会影响手指长度的估计。我们的目的是使用非自然的听觉输入在基于手的视觉错觉使用增强现实，以评估是否增加听觉输入会增加主观错觉强度和基于性能的任务的措施。44名参与者完成了以下三个条件：没有手指伸展，没有触觉反馈的手指伸展和有触觉反馈的手指伸展。一半的参与者在所有条件下都有听觉输入，而另一半则没有。在每个条件下，参与者被给予以下三个性能任务之一：刺激（右）手点触摸任务，非刺激（左）手点触摸任务，和一个标尺判断任务。点任务涉及参与者达到一个虚拟点的位置，而标尺任务涉及参与者自己的手指在标尺上的估计，而手从视图中隐藏。在所有的试验之后，参与者完成了一份问卷，以捕捉主观错觉的强度。除了听觉输入增加主观错觉强度的操作没有触觉反馈，但不是那些与触觉反馈。没有发现任何性能任务的音频的促进作用。我们的结论是，在没有触觉反馈的情况下，将听觉输入添加到虚幻的手指伸展中会增加主观的虚幻体验，但不会影响基于性能的测量。在线版本包含补充材料，可通过10.1007/s 00221 -023-06759-7获得。
Bodily resizing illusions typically use visual and/or tactile inputs to produce a vivid experience of one’s body changing size. Naturalistic auditory input (an input that reflects the natural sounds of a stimulus) has been used to increase illusory experience during the rubber hand illusion, whilst non-naturalistic auditory input can influence estimations of finger length. We aimed to use a non-naturalistic auditory input during a hand-based resizing illusion using augmented reality, to assess whether the addition of an auditory input would increase both subjective illusion strength and measures of performance-based tasks. Forty-four participants completed the following three conditions: no finger stretching, finger stretching without tactile feedback and finger stretching with tactile feedback. Half of the participants had an auditory input throughout all the conditions, whilst the other half did not. After each condition, the participants were given one of the following three performance tasks: stimulated (right) hand dot touch task, non-stimulated (left) hand dot touch task, and a ruler judgement task. Dot tasks involved participants reaching for the location of a virtual dot, whereas the ruler task concerned estimates of the participant’s own finger on a ruler whilst the hand was hidden from view. After all trials, the participants completed a questionnaire capturing subjective illusion strength. The addition of auditory input increased subjective illusion strength for manipulations without tactile feedback but not those with tactile feedback. No facilitatory effects of audio were found for any performance task. We conclude that adding auditory input to illusory finger stretching increased subjective illusory experience in the absence of tactile feedback but did not affect performance-based measures.
