How do we map joint actions we participate in onto joint actions we observe others performing, such as when a couple dancing tango observes another couple dancing tango? We investigated this question using a task in which participants were instructed to perform individual or joint movements in synchrony with individual or joint movements observed on a computer screen. The observed movements started slowly and then continuously increased in tempo (from 1.75 Hz to 3 Hz). The results showed that, with regard to spatial parameters, joint performance was more accurate when observing joint action than when observing individual action (Experiments 1, 1a, and 1b). Individual performance was more accurate when observing individual action than when observing joint action (Experiments 3 and 4). There were no systematic differences with regard to timing parameters. These results suggest that mechanisms of temporal coordination may be less susceptible to differences between individual and joint action than mechanisms of spatial matching.
我们如何将自己参与的联合动作映射到我们观察他人执行的联合动作上，比如当一对跳探戈的舞伴观察另一对跳探戈的舞伴时？我们使用一项任务来研究这个问题，在该任务中，参与者被指示与在电脑屏幕上观察到的个体或联合动作同步执行个体或联合动作。观察到的动作开始时较慢，然后节奏持续加快（从1.75赫兹到3赫兹）。结果表明，在空间参数方面，观察联合动作时的联合表现比观察个体动作时更准确（实验1、1a和1b）。观察个体动作时的个体表现比观察联合动作时更准确（实验3和4）。在时间参数方面没有系统差异。这些结果表明，与空间匹配机制相比，时间协调机制可能不太容易受到个体动作和联合动作之间差异的影响。
