我们调查了人们在共同执行联合行动时是否会监控自己和伴侣的个人行动的结果以及联合行动的结果。两位钢琴家背诵了钢琴二重奏的两个部分。然后，每位钢琴家演奏一个部分，而他们的搭档则演奏另一部分；记录两者的脑电图。与钢琴家产生的击键相关的听觉结果（音高）偶尔会以影响或不影响联合听觉结果（即，由两位钢琴家“组合音高”产生的和弦的和声）的方式改变。改变的听觉结果会引起与反馈相关的消极性，无论它们发生在钢琴家自己的部分还是合作伙伴的部分，也无论它们是否影响个人或联合行动的结果。改变的听觉结果还引发了 P300，当改变影响联合结果时（与个体结果相比），以及当改变影响钢琴家自己的部分（与合作伙伴的部分相比）时，其幅度更大。因此，参与联合行动的音乐家监控他们自己和他们的合作伙伴的行动以及他们的联合行动结果，同时保持他们自己和他人的行动之间以及个人和联合结果之间的区别。
We investigated whether people monitor the outcomes of their own and their partners 'individual actions as well as the outcome of their combined actions when performing joint actions together. Pairs of pianists memorized both parts of a piano duet. Each pianist then performed one part while their partner performed the other; EEG was recorded from both. Auditory outcomes (pitches) associated with keystrokes produced by the pianists were occasionally altered in a way that either did or did not affect the joint auditory outcome (i.e., the harmony of a chord produced by the two pianists 'combined pitches). Altered auditory outcomes elicited a feedback-related negativity whether they occurred in the pianist's own part or the partner's part, and whether they affected individual or joint action outcomes. Altered auditory outcomes also elicited a P300 whose amplitude was larger when the alteration affected the joint outcome compared with individual outcomes and when the alteration affected the pianist's own part compared with the partner's part. Thus, musicians engaged in joint actions monitor their own and their partner's actions as well as their combined action outcomes, while at the same time maintaining a distinction between their own and others' actions and between individual and joint outcomes.
