In an upright stance, individuals sway in unpredictable ways. Their eyes also move in unpredictable ways in fixation tasks. The objective of this study was to analyze visual functions, postural control, and cognitive involvement in stationary gaze. A total of 14 healthy young adults performed a fixation task and a free-viewing task (three trials per task, 45 s per trial). As expected, the results showed many (n = 32) significant positive Pearson correlation coefficients between the eye and center of pressure/body (head, neck, and lower back) movements in the fixation task. In the free-viewing task, the correlations were nonsignificant. Only 3 of the 32 significant correlations (9.4%) were significantly related to cognitive involvement (measured with a subjective questionnaire). These results indirectly strengthened the validity of the synergistic model of postural control.

垂直执行固定任务时视力与姿势之间的正向关系。

在直立的立场上，个人以不可预测的方式摇摆。在注视任务中，他们的眼睛也以无法预测的方式移动。这项研究的目的是分析视觉功能，姿势控制和固定视线中的认知参与。总共14位健康的年轻人执行了固定任务和自由观看任务（每个任务3次试验，每次试验45 s）。正如预期的那样，在固定任务中，眼睛与压力中心/身体（头部，颈部和下背部）运动之间存在许多（n = 32）显着的Pearson正相关系数。在自由观看任务中，相关性不显着。在32个显着相关中，只有3个（9.4％）与认知受累显着相关（使用主观问卷进行测量）。
