Blindfolding candidates when testing their tactile performance may increase their anxiety. This study examined whether different visual barriers would influence tactile performance on timed tasks. It was hypothesised that candidates using a blindfold would be more anxious, but that they would benefit by the potentially positive effects of arousal on performance and not differ from candidates using a screen to limit visual access to task material. 200 participants (ages 19 to 30 years), randomly assigned to the two conditions, completed a tactile perception task, as well as an anxiety scale. In contrast to the expected outcome, the screen sample took significantly longer to complete the task. This was hypothesised to be the result of increased distraction given competing cross-modal attentional demands and the consequent visual and tactile attention switching. Practitioners may need to consider the influences of visual interference when assessing tactile performance.
在测试触觉表现时对考生进行蒙眼可能会增加他们的焦虑。本研究旨在检验不同的视觉障碍是否会影响限时任务中的触觉表现。研究假设使用眼罩的考生会更加焦虑，但他们可能会受益于唤醒对表现的积极影响，与使用屏幕限制任务材料视觉接触的考生并无差异。200 名参与者（年龄 19 至 30 岁）被随机分配到两种条件下，完成了一项触觉感知任务以及一份焦虑量表。与预期结果相反，使用屏幕的样本完成任务的时间明显更长。这被假设是由于竞争的跨模态注意力需求以及随之而来的视觉和触觉注意力转换，导致注意力分散增加的结果。评估触觉表现时，从业者可能需要考虑视觉干扰的影响。
