The authors determined the effects of changes in task demands on interpersonal and intrapersonal coordination. Participants performed a joint task in which one participant held a stick to which a circle was attached at the top (holding role), while the other held a pointer through the circle without touching its borders (pointing role). Experiment 1 investigated whether interpersonal and intrapersonal coordination varied depending on task difficulty. Results showed that interpersonal and intrapersonal coordination increased in degree and stability with increments in task difficulty. Experiment 2 explored the effects of individual constraints by increasing the balance demands of the task (one or both members of the pair stood in a less stable tandem stance). Results showed that interpersonal coordination increased in degree and stability as joint task demands increased and that coupling strength varied depending on joint and individual task constraints. In all, results suggest that interpersonal and intrapersonal coordination are affected by the nature of the task performed and the constraints it places on joint and individual performance.
作者研究了任务需求变化对人际和内省协调的影响。参与者完成了一个联合任务，其中一名参与者拿着一根顶部附有圆圈的棍子（握持角色），而另一名参与者拿着一个指针穿过圆圈但不触及其边界（指向角色）。实验 1 研究了人际和内省协调是否取决于任务难度。结果表明，随着任务难度的增加，人际和内省协调在程度和稳定性上都有所增加。实验 2 通过增加任务的平衡需求（对或双方成员站在不太稳定的串联姿势）来探索个体约束的影响。结果表明，随着联合任务需求的增加，人际协调在程度和稳定性上都有所增加，并且耦合强度取决于联合和个体任务约束。总的来说，结果表明人际和内省协调受到所执行任务的性质以及它对联合和个体表现的限制的影响。
