Özet:
It has been proposed that postural movements can be controlled so as to facilitate visual performance. Tasks that require more precise visual fixations should result in a decrease in postural sway variability. Three experiments were conducted that focused on (1) differences in postural behavior when tracking a moving versus stationary target, and (2) differences in postural behavior under constraints on visual performance theoretically unrelated to eye movements in a target detection task. In the first two experiments, sway variability was reduced when tracking a moving target relative to a stationary one. In the third experiment, sway variability was reduced when performing a more difficult target detection task, but only towards the latter part of the experiment. It seems that the functional relation between body sway and task demands developed over trials. Overall results suggest that postural behavior can be used to facilitate the achievement of other tasks. Results also suggest potential postural learning for more complex tasks to achieve adequate visual performance. Implications for the design of human-machine systems were discussed.
