| 摘 要： | 为揭示认知任务对直立姿势的视觉控制的影响, 本研究采用双重任务的方法, 要求18名健康的成年被试在4种条件(2认知条件×2视觉条件)下尽力保持直立姿势的稳定。姿势动摇的测量采用头顶拍摄的方法并计算误差均方根、平均速度以及Romberg商数。研究结果显示认知任务和视觉条件之间的交互作用显著, 而且当有认知任务时姿势动摇的Romberg商数显著降低。这些结果说明认知任务抑制了直立姿势控制过程中的视觉加工。

| Abstract: | Normal postural control has traditionally been considered an automatic or reflex process using minimal attentional resources. Recent research has provided evidence against this assumption and shown that postural control could be influenced by posture-unrelated cognitive activity. However, it was not clear whether posture-cognition interferences were due to limited central information-processing capacity, or the U-shaped relationship between physiological arousal and postural control. The purpose of the pres... |
