What is the key to successful interaction? Is it sufficient to represent a common goal, or does the way our partner achieves that goal count as well? How do we react when our partner misbehaves? We used a turn-taking music-like task requiring participants to play sequences of notes together with a partner, and we investigated how people adapt to a partner's error that violates their expectations. Errors consisted of either playing a wrong note of a sequence that the agents were playing together (thus preventing the achievement of the joint goal) or playing the expected note with an unexpected action. In both cases, we found post-error slowing and inaccuracy suggesting the participants' implicit tendency to correct the partner's error and produce the action that the partner should have done. We argue that these "joint" monitoring processes depend on the motor predictions made within a (dyadic) motor plan and may represent a basic mechanism for mutual support in motor interactions.
成功互动的关键是什么？仅仅代表共同目标就足够了，还是我们的合作伙伴实现目标的方式也很重要？当我们的合作伙伴行为不当时，我们会作何反应？我们使用了一种类似于轮流的音乐任务，要求参与者与合作伙伴一起演奏音符序列，并研究了人们如何适应违反他们期望的合作伙伴的错误。错误要么是演奏了参与者一起演奏的序列中的错误音符（从而阻止了共同目标的实现），要么是用意外的动作演奏了预期的音符。在这两种情况下，我们都发现了错误后减速和不准确，这表明参与者有内在的倾向来纠正合作伙伴的错误，并做出合作伙伴应该做的动作。我们认为，这些“共同”监测过程取决于（对偶）运动计划内的运动预测，并且可能代表了运动相互作用中相互支持的基本机制。
