大多数关于人类运动的研究只倾向于考虑单个受试者在静止环境中独自行走。然而，人类受试者往往计划和产生他们的运动轨迹根据彼此的位移。因此，在本研究中，我们解决的问题，人际协调时，对受试者同时行走。在我们的实验中，六对受试者在8 m x 2 m的轨道上面对面、前后行走。在每一对中，领导者（L）被要求打破最初的人际距离，而追随者（F）必须保持这个距离不变（1，2或3米）。我们测量了它们的位置，并分析了它们的行程，它们的线性位移的时间过程，和它们的步骤的运动学参数。我们的研究结果表明，F旅行的距离小于L，即使它们是高度相关的，一些时间延迟之间的位移L和F的值更大时，人际距离增加（从1到3米）。这些结果进行了讨论，在高层次的模仿，即双向互动与相互影响的每个主题对彼此。(C)2005爱思唯尔爱尔兰有限公司保留所有权利。
Most studies about human locomotion only tend to consider single subjects walking alone in a stationary environment. Nevertheless, human subjects have often to plan and generate their locomotor trajectories according to one another's displacements. Therefore, in the present study we address the question of the interpersonal coordination when pairs of subjects walk simultaneously. Six pairs of subjects walking face to face, backwards and forwards on a 8 m x 2 m track were involved in our experiment. Within each pair, the leader (L) was required to break the initial interpersonal distance whereas the follower (F) had to maintain this distance constant (1, 2 or 3 m). We measured their position and analyzed their travelled distance, the time course of their linear displacement, and the kinematics parameters of their steps. Our results show that F travels smaller distances than L and that even if they are highly correlated, some temporal delays exist between displacements of L and F with greater values when the interpersonal distance increases (from 1 to 3 m). These results are discussed in terms of high level imitation, i.e. bidirectional interactions with mutual influences of each subject on one another. (C) 2005 Elsevier Ireland Ltd. All rights reserved.
