钢琴演奏中的自我与他人：定时扰动的可检测性取决于个人演奏风格

与其他人的运动的重复之间的差异相比，更容易检测到自己的运动的记录重复之间的差异，这表明由于观察者的动作系统中的增强的共振和/或相对准确的内部动作模拟而改善的视觉辨别（Daprati等人，Conscious Cogn 16：178-188，2007）。在实验1中，我们试图在听觉通道中复制这一发现。钢琴家被录下三次演奏音乐摘录，然后判断成对的录音是同一段还是同一段的不同段。他们并不善于区分自己演奏的不同片段，也不善于区分其他钢琴家演奏的不同片段，尽管他们的辨别力和自我认知远远超出了偶然性。在实验2中，同样的钢琴家试图检测人为引入的小的局部时间偏差。他们在自己的演奏中比在另一位钢琴家的演奏中更善于发现这种偏差，但前提是这些偏差被放置在预先存在的自我-他人局部计时差异的点上。在这种情况下，钢琴家预测自己特有动作模式的能力确实有助于他们对时间不规则性的感知。这些结果并不支持Daprati等人在音乐领域的知觉锐化假设，但它们确实表明，钢琴家在聆听演奏时产生了特殊的时间期望，可能是通过内部动作模拟。
Differences between recorded repetitions of one’s own movements are detected more readily than are differences between repetitions of others’ movements, suggesting improved visual discrimination due to heightened resonance in the observer’s action system and/or relatively accurate internal action simulation (Daprati et al. in Conscious Cogn 16:178–188, 2007). In Experiment 1, we attempted to replicate this finding in the auditory modality. Pianists were recorded playing musical excerpts three times and later judged whether pairs of recordings were the same take or different takes of the same excerpt. They were no better at distinguishing different takes of their own playing than those of other pianists’ playing, even though discrimination and self-recognition were well above chance. In Experiment 2, the same pianists tried to detect small local timing deviations that had been introduced artificially. They were better at detecting such deviations in their own performances than in those of another pianist, but only if the deviations were placed at points of a pre-existing self-other difference in local timing. In that case, pianists’ ability to predict their own characteristic action pattern did aid their perception of temporal irregularity. These results do not support the perceptual sharpening hypothesis of Daprati et al. in the musical domain, but they do suggest that pianists listening to performances generate idiosyncratic temporal expectations, probably through internal action simulation.
