The primary intent of this investigation was to determine if stabilizing complexity (postural control) influenced lower limb selection while performing a bilateral footedness task. Right- and left-footed subjects (as determined by a bilateral preference inventory) were asked to stand on one foot and tap a telegraph key with the opposite foot repeatedly. The bilateral task was conducted in two conditions of stabilizing complexity, with the intent to augment focus of attention between stabilizing and mobilizing limb: simple (lights on) and complex (limitation of visual cues). Results indicated that in both simple and complex conditions, 50% or more of subjects switched stabilizing limbs or showed no preference when comparing preference inventory behavior to experimental conditions, suggesting, in general, that foot preference may be in part dependent on the context of the task and not tied predominantly to biological theory.
本研究的主要目的是确定在执行双侧惯用脚任务时，稳定复杂性（姿势控制）是否会影响下肢的选择。右利脚和左利脚的受试者（通过双侧偏好量表确定）被要求单脚站立，并用另一只脚反复敲击电键。双侧任务在两种稳定复杂性条件下进行，目的是增强对稳定和移动肢体之间注意力的关注：简单条件（灯亮）和复杂条件（视觉线索受限）。结果表明，在简单和复杂条件下，当将偏好量表行为与实验条件进行比较时，50%或更多的受试者更换了稳定肢体或没有表现出偏好，这总体上表明，脚的偏好可能部分取决于任务背景，而不是主要与生物学理论相关。
