Abstract：
Motor contagions refer to implicit effects induced by the observation of actions made by others on one\'s own actions. A plethora of studies conducted over the last two decades have demonstrated that both observed and predicted actions can induce various kinds of motor contagions in a human observer. However, motor contagions have always been investigated with regard to different features of an observed action, and it remains unclear whether the background environment in which an observed action takes place modulates motor contagions as well. Here, we investigated participant movements in an empirical hand steering task during which the participants were required to move a cursor through a visual channel after being presented with videos of an actor performing the same task. We manipulated the congruency between the actions shown in the video and the background channels and examined whether and how they affected the participants\' own movements. We observed a clear interaction between the observed action and its background. The movement time of the participants\' actions tended to increase or decrease depending on whether they observed a faster or slower movement, respectively, and these changes were amplified if the background was not congruent with the action contained within it. These results suggest that background information can modulate motor contagions in humans.
摘要：
运动传染是指通过观察他人对自己行为的行为而引起的内隐效应。在过去的二十年中进行的大量研究表明，观察到的和预测的动作都可以在人类观察者中引起各种运动传染。然而,运动传染一直是针对观察到的动作的不同特征进行研究的，目前尚不清楚观察到的动作发生的背景环境是否也能调节运动传染。这里,我们调查了一项经验性手动转向任务中参与者的动作,在该任务期间,参与者在被呈现了执行相同任务的演员的视频后,被要求通过视觉通道移动光标.我们操纵了视频中显示的动作和背景频道之间的一致性，并检查了它们是否以及如何影响参与者自己的动作。我们观察到观察到的作用与其背景之间存在明显的相互作用。参与者动作的运动时间倾向于增加或减少，取决于他们观察到的运动是更快还是更慢，分别,如果背景与其中包含的动作不一致，这些变化就会被放大。这些结果表明，背景信息可以调节人类的运动传染病。
