在协作问题解决(CPS)过程中,协调发生在不同的空间和时间尺度上。这种多尺度协调应该在促进有效协作方面发挥功能性作用。为了评估这一点,我们对 42 个双团队进行了一项基于计算机的 CPS 研究。我们使用交叉小波相干性来检查从视频中提取的多个尺度的运动协调,并测试观察到的协调是否由于偶然和任务要求而大于预期。我们发现,在小于 2s 的尺度上,协调大于偶然,并且在大多数尺度(16s、1m 和 2m 除外)下,由于任务需求,协调大于预期。最后,我们观察到 0.25 秒和 1 秒尺度的一致性可以预测性能。然而,当包括相对相位时,我们的结果表明 1s 尺度上较高的同相运动协调是 CPS 性能的最强预测因子。此外,我们使用生长曲线模型来检查运动协调在任务持续时间内如何变化,以及这是否受到 CPS 表现的调节。我们发现,CPS 任务持续时间内的协调是二次的(U 形),表现较好的团队具有较高的协调性,且曲线较浅。我们讨论这些发现及其与理解低水平运动协调如何促进 CPS 的相关性。
During collaborative problem solving (CPS), coordination occurs at different spatial and temporal scales. This multiscale coordination should play a functional role in facilitating effective collaboration. To evaluate this, we conducted a study of computer-based CPS with 42 dyadic teams. We used cross-wavelet coherence to examine movement coordination, extracted from videos, at several scales, and tested whether the observed coordination was greater than expected due to chance and due to task demands. We found that coordination at scales less than 2s was greater than chance and at most scales (except 16s, 1m, and 2m), was greater than expected due to task demands. Lastly, we observed that coherence at .25s and 1s scales was predictive of performance. However, when including relative phase, our results suggest that higher in-phase movement coordination at the 1s scale was the strongest predictor of CPS performance. Further, we used growth curve modeling to examine how movement coordination changes across the duration of the task and whether this is moderated by CPS performance. We found that coordination over the duration of the CPS task is quadratic (a U shape) and that better performing teams have higher coordination with a shallower curve. We discuss these findings and their relevance to understanding how low-level movement coordination facilitates CPS.
