Abstract

Purpose. How demands of precision influence the performance during alternated discrete touching is not well established in the literature. Hence, we compared both hands performance during alternated touching, manipulating the precision demand. Methods. Overall, 23 right-handed adults participated in this study. the first task consisted of alternated touching with a pencil on both sides of a blank paper, performing as fast as possible, considering the first touch as reference for the next ones. Subsequently, touch dispersion and width were measured, and circular targets were drawn with those proportions. the second task consisted of performing as many hits as possible inside those targets. Apart from the delimitated target, increasing precision demand, the task parameters were equal. Results. Movement time increased and the number of touches decreased from the first to the second task. However, the preferred hand displayed greater reductions in performance. Conclusions. the perceptual constraint of adding a visual target affects motor control parameters in alternated touching, causing decrements in performance in both hands, but more evidently in the preferred right hand.
在交替的离散触摸过程中,对精度的要求对手的影响是不同的
目的。在文献中,精度要求如何影响交替离散接触时的性能尚未得到很好的确定。因此,我们比较了双手在交替触摸时的表现,操纵精度需求。方法。总共有23名惯用右手的成年人参与了这项研究。第一项任务是用铅笔在空白纸的两面交替触碰,动作要尽可能快,并将第一次触碰作为下一次触碰的参考。随后,测量触摸分散和宽度,并根据这些比例绘制圆形目标。第二个任务包括在这些目标内执行尽可能多的命中。除了分割目标,提高精度要求外,任务参数相等。结果。从第一个任务到第二个任务,移动时间增加,触摸次数减少。然而,惯用手表现出更大的性能下降。结论。增加视觉目标的知觉约束会影响交替触摸时的运动控制参数,导致双手动作性能下降,但对首选右手的影响更为明显。
