We investigated whether body-scaled action is influenced by awareness of task performance. Participants walked through apertures varying in size. Awareness of performing the action was manipulated by asking half of the participants to concurrently perform a haptic memory task. Distracted participants showed a smaller maximum amount of shoulder rotation at A/S(crit). Walking through apertures thus seems a rather automatic/uniform process regarding action planning, but being distracted from performing the action appears to influence how the action is performed, and may increase its efficiency.
我们研究了身体尺度的动作是否受任务执行意识的影响。参与者穿过大小各异的孔洞。通过要求一半的参与者同时执行一项触觉记忆任务来操纵动作执行的意识。分心的参与者在A/S（临界值）处的肩部最大旋转量较小。因此，就动作规划而言，穿过孔洞似乎是一个相当自动/统一的过程，但因执行动作而分心似乎会影响动作的执行方式，并可能提高其效率。
