The relation between verticality perception and body balance as influenced by perceptual style, age, and sex was investigated in 100 subjects. Perceptual style was measured by the Rod and Frame Test. Body balance data were obtained by two electromechanical force plates. The results of the measurements of perceptual style indicated that the younger groups were more accurate in estimating verticality than the older groups and that men were more accurate than women. With regard to the body balance shift data, however, no significant differences relative to age, sex, or perceptual style were found. The rejection of the hypothesis concerning body balance shift was interpreted in terms of the dominant influence of proprioceptive cues over visual cues in maintaining body balance. In normal standing activities, as long as the neuromuscular system is intact, conflicting stimuli from the visual field appear to have little effect on modifying body balance.
在100名受试者中研究了感知方式、年龄和性别对垂直感知与身体平衡之间关系的影响。通过杆框测验测量感知方式。通过两个机电测力板获取身体平衡数据。感知方式测量结果表明，较年轻组在估计垂直方向上比较年长组更准确，且男性比女性更准确。然而，关于身体平衡偏移数据，未发现与年龄、性别或感知方式相关的显著差异。关于身体平衡偏移的假设被否定，这被解释为本体感觉线索在维持身体平衡方面比视觉线索具有主导影响。在正常站立活动中，只要神经肌肉系统完好无损，来自视野的冲突刺激似乎对改变身体平衡影响很小。
