When we speak and sing we not only produce sounds, but also hear the sounds we produce. The importance of monitoring our own sounds is dramatized by the speech of deaf persons, or the difficulty experienced when singing the national anthem in a large, reverberating hall. However, puzzling evidence from past research would suggest that perceptual feedback plays a limited role in the execution of actions. Dr. Peter Q. Pfordresher will further explore this puzzle with support from the National Science Foundation. The key question of his research is to what extent does fluency in action rely on perceiving the results of one's actions? The funded research focuses on the sounds people hear while they play melodies on the piano. In this research, participants perform short melodies from memory while listening to themselves over headphones. During certain performances, the sounds the performer hears deviate in various ways from the produced actions. For example, one might hear the wrong musical pitch when a key is pressed, might hear the correct pitch after a delay, or hear nothing at all. Past research of this sort has revealed that some deviations are more disruptive than others, and different kinds of deviations disrupt different characteristics of performance. The Broader Impacts of the funded research will ultimately include understanding the way coordination goes awry in certain disorders such as stuttering.

当我们说话和唱歌时，我们不仅发出声音，而且还听到我们发出的声音。 聋人的讲话，或者在一个巨大的、回荡的大厅里唱国歌时所经历的困难，都突出了监控我们自己声音的重要性。 然而，令人困惑的证据从过去的研究表明，知觉反馈在执行行动中发挥的作用有限。 Peter Q.博士Pfordresher将在国家科学基金会的支持下进一步探索这个难题。 他研究的关键问题是，行动的流畅性在多大程度上依赖于对行动结果的感知？ 这项研究的重点是人们在钢琴上演奏旋律时听到的声音。 在这项研究中，参与者在通过耳机听自己说话的同时，根据记忆演奏简短的旋律。 在某些表演中，表演者听到的声音以各种方式偏离所产生的动作。 例如，当按下一个键时，可能会听到错误的音高，可能会在延迟后听到正确的音高，或者根本听不到。 过去的这类研究表明，有些偏差比其他偏差更具破坏性，不同类型的偏差会破坏不同的绩效特征。 资助研究的更广泛影响最终将包括理解在某些疾病（如口吃）中协调出错的方式。
