当我们感知到环境中的运动时，即使我们对这种运动没有感觉运动体验，运动系统也会参与其中。有人认为，这种能力依赖于内部模型，包括特定的外感受性表征，如听觉和视觉。研究表明，对于人类的动作，感知的质量取决于感知到的动作和感知者自己再现动作的能力之间的接近程度，因此，如果我们能够再现一个动作，我们也就拥有了内感受运动记忆，使我们能够运行内部模型，并在仅仅观察时更准确地感知相同的动作。在一项行为研究中，我们调查了参与者是否能够从先前记录的跨栏表演中区分自己产生的和他人产生的运动声音。我们还分析了参与者的辨别能力是否会随着特定声音特征的变化而变化，检查节奏步骤结构和幅度范围。结果显示，参与者能够区分自己和他人的运动声音。然而，改变节奏的步骤结构或幅度范围的声音并不影响这种自我他者的歧视。我们认为，一个人自己的运动声音的识别是作为一个听觉完形整体实现的。
The motor system is engaged when we perceive movement in the environment, even when we have no sensorimotor experience of that movement. It has been suggested that this ability relies on internal models that comprise specific exteroceptive representations, such as audition and vision. It has been shown that, for human movements, the quality of perception depends on the closeness between the perceived movement and the perceiver's own capability of reproducing it. Thus, if we are able to reproduce a movement, we also have the interoceptive motor memories that enable us to run internal models and perceive the same movements more accurately when merely observed. In a behavioral study we investigated if participants would be able to distinguish between self-produced and other-produced movement sounds from a previously recorded hurdling performance. We also analyzed if participants' discriminative ability would vary as a function of specific sound features, examining rhythmic step structure and amplitude range. The results reveal that participants were able to distinguish between their own and others' movement sounds. However, changing either rhythmic step structure or amplitude range of the sounds did not influence this self other discrimination. We suggest that identification of one's own movement sounds is holistically achieved as an auditory gestalt.
