项目摘要

The standing posture is maintained by the integration of sensory functions with different modalities, i.e. visual, vestibular, and somatosensory functions. We have previously found that anxiety influences the frequency component of body sway (BS) of the antero-posterior axis in college students during orthostatic standing while gazing at a visual cue in front of them (Wada et al., 2001). The influence of anxiety on BS is observed in participants standing with their eyes open, but diminished with eyes closed. Therefore, we have hypothesized that the degree of anxiety affects the processing of visual information and/or the interaction between visual input and other two sensory inputs in standing humans. Furthermore, the possibility has been raised that humans with higher anxiety perceive the spacial distance, including the cognition of interpersonal distance, in a different manner from that of humans with lower anxiety. Our experiment employing the within-subject design has shown that the degree of anxiety positively correlates with the maximum length of the antero-posterior BS and thus the total area of BS in the same persons (Ohno et al., 2004, 2005). These influences of anxiety on the performance of BS are also diminished when eyes are closed. In 2004, we have examined the effect of exchanging the visual cue from external landmark to internal one. Mental arithmetic is carried out by viewing the internal tables. Therefore, we have observed the effects of anxiety on BS during mental arithmetic with eyes open. No influence of anxiety has been observed in BS with mental arithmetic. This result shows that the processing of visual input from the external milieu is essential for anxiety to influence the postural balance. Our experiment in 2005 has shown that anxiety does not influence the antero-posterior BS induced by an electrical stimulation of the vestibular organs.

站立姿势是通过整合不同形式的感觉功能来维持的，即视觉、前庭和躯体感觉功能。我们先前已经发现，焦虑会影响大学生在直立时凝视前方视觉线索时的前后轴体摆动频率(BS)(Wada et al.，2001)。焦虑对BS的影响在参与者中观察到，他们睁着眼睛站着，但闭着眼睛时焦虑的影响会减弱。因此，我们假设焦虑程度会影响站立人类视觉信息的加工和/或视觉输入与其他两种感觉输入之间的相互作用。此外，还提出了一种可能性，即焦虑程度较高的人感知空间距离的方式与焦虑程度较低的人不同，包括对人际距离的认知。我们采用被试内部设计的实验表明，焦虑程度与前后脑BS的最大长度正相关，从而与同一人的BS总面积呈正相关(Ohno等，2004,2005)。当闭上眼睛时，焦虑对BS表现的影响也会减弱。2004年，我们考察了从外部地标到内部地标的视觉线索交换的效果。通过查看内部表格来执行心算。因此，我们在睁开眼睛进行心算的过程中观察了焦虑对BS的影响。没有观察到焦虑对心算能力的影响。这一结果表明，来自外部环境的视觉输入的加工对于焦虑影响姿势平衡是必不可少的。我们在2005年的实验表明，焦虑并不影响前庭器官电刺激所引起的前后部BS。
