飞机着陆是一项复杂的任务，需要有效的注意力控制才能成功。本研究探讨了如何焦虑可能会影响凝视行为在模拟着陆的性能。参加者在低能见度条件下进行了模拟着陆，需要使用驾驶舱仪表以获得制导信息。着陆是在焦虑或控制条件下进行的，焦虑是通过自我威胁指令和金钱激励的组合来操纵的。结果显示，在焦虑条件下，对外界的停留时间百分比增加。视觉扫描熵是视觉扫描行为的预测性指标，在焦虑状态下，视觉扫描行为的随机性增加。此外，扫描随机性从预测试到焦虑条件的变化与认知焦虑的变化和表现错误的变化呈正相关。这些结果支持了焦虑会对注意控制产生负面影响的观点。(c)2014年学会在记忆和认知应用研究。爱思唯尔公司出版All rights reserved.
Landing an aircraft is a complex task that requires effective attentional control in order to be successful. The present study examined how anxiety may influence gaze behavior during the performance of simulated landings. Participants undertook simulated landings in low visibility conditions which required the use of cockpit instruments in order to obtain guidance information. Landings were performed in either anxiety or control conditions, with anxiety being manipulated using a combination of ego-threatening instructions and monetary incentives. Results showed an increase in percentage dwell time toward the outside world in the anxiety conditions. Visual scanning entropy, which is the predictability of visual scanning behavior, showed an increase in the randomness of scanning behavior when anxious. Furthermore, change in scanning randomness from the pre-test to anxiety conditions positively correlated with both the change in cognitive anxiety and change in performance error. These results support the view point that anxiety can negatively affect attentional control. (c) 2014 Society for Applied Research in Memory and Cognition. Published by Elsevier Inc.
