The goal of this study was to identify the control mechanism used for locomotion pointing regulation under different external temporal constraints. Subjects ( n=8) had to walk on a treadmill through a number of virtual hallways and cross a pair of gliding doors that opened and closed at a constant preset frequency (0.5 Hz or 1 Hz). Crossing performance, step durations, and step lengths were used as dependent measures. The results revealed the regulation of locomotion occurred earlier and was more pronounced at 0.5 Hz than at 1 Hz, making performance better at 0.5 Hz. Nevertheless at the two frequencies the control mechanism appears similar; it is grounded on information movement coupling. This control mechanism allows for the production of specific behavior according to the task constraints.
本研究的目的是确定在不同外部时间限制下用于运动指向调节的控制机制。受试者（n = 8）必须在跑步机上走过多个虚拟走廊，并穿过一对以恒定预设频率（0.5赫兹或1赫兹）打开和关闭的滑动门。通过性能、步长和步幅作为因变量进行测量。结果显示，与1赫兹相比，运动调节在0.5赫兹时出现得更早且更明显，使得在0.5赫兹时的表现更好。然而，在这两个频率下，控制机制似乎相似；它基于信息运动耦合。这种控制机制允许根据任务限制产生特定行为。
