论文摘要
对象介导的联合作用被认为可以通过使用其相互作用力中微妙的触觉信号之间的互动个体之间的隐式信息交换来实现。但是，这些触觉信号的特征尚不清楚。在这里，我们使用Granger-Geweke因果关系分析分析了经验二元相互作用任务中的相互作用力，这使我们能够量化每个人的力量对伴侣的因果影响。我们观察到，在每个频率下，伴侣的影响都不相同。具体而言，在[2.15-7] Hz的频带中，我们观察到了因果影响的互间差异，这些因素是任务中运动频率不变的，并且仅在信息交换对于任务执行必不可少的情况下才出现。此外，观察到该频带中的内部差异与二元组与任务性能相关。我们的结果表明，[2.15-7] Hz频段中的力构成了身体相互作用期间个体之间与任务相关的信息交换。
Object-mediated joint action is believed to be enabled by implicit information exchange between interacting individuals using subtle haptic signals within their interaction forces. The characteristics of these haptic signals have, however, remained unclear. Here we analyzed the interaction forces during an empirical dyadic interaction task using Granger-Geweke causality analysis, which allowed us to quantify the causal influence of each individual's forces on their partner's. We observed that the inter-partner influence was not the same at every frequency. Specifically, in the frequency band of [2.15-7] Hz, we observed inter-partner differences of causal influence that were invariant of the movement frequencies in the task and present only when information exchange was indispensable for task performance. Moreover, the interpartner difference in this frequency band was observed to be correlated with the task performance by the dyad. Our results suggest that forces in the [2.15-7] Hz band constitute task related information exchange between individuals during physical interactions.
