心理身体表征是高度可塑性的，在短暂接触意想不到的感觉反馈后可以修改。虽然视觉、触觉和本体感觉在塑造身体表征中的作用已经被许多研究所强调，但听觉对心理身体表征的影响仍然知之甚少。最近有证据表明，当一个人的身体撞击表面时，通过操纵自然声音产生的身体表征的变化。但这些变化也会发生在非自然主义的声音上吗？非自然主义的声音没有提供关于身体产生或对身体产生影响的信息。我们让受试者在没有手部视觉信息的情况下，用左手拉动右手食指尖端，同时听到短暂的上升、下降或恒定的音调，利用音调的动态变化来引发垂直平面上的运动和物体大小变化的印象。结果显示了一种“听觉皮诺曹”效应，参与者感觉并估计他们的手指在上升音调后会更长。这些结果提供了第一个证据，表明不代表真实运动的声音，如非自然主义的声音，当与身体动作任意配对时，可以诱导身体表征的匹诺曹样变化。
Mental body-representations are highly plastic and can be modified after brief exposure to unexpected sensory feedback. While the role of vision, touch and proprioception in shaping body-representations has been highlighted by many studies, the auditory influences on mental body-representations remain poorly understood. Changes in body-representations by the manipulation of natural sounds produced when one’s body impacts on surfaces have recently been evidenced. But will these changes also occur with non-naturalistic sounds, which provide no information about the impact produced by or on the body? Drawing on the well-documented capacity of dynamic changes in pitch to elicit impressions of motion along the vertical plane and of changes in object size, we asked participants to pull on their right index fingertip with their left hand while they were presented with brief sounds of rising, falling or constant pitches, and in the absence of visual information of their hands. Results show an “auditory Pinocchio” effect, with participants feeling and estimating their finger to be longer after the rising pitch condition. These results provide the first evidence that sounds that are not indicative of veridical movement, such as non-naturalistic sounds, can induce a Pinocchio-like change in body-representation when arbitrarily paired with a bodily action.
