Firefighters as a profession are required to maintain high levels of attention for prolonged periods. However, total sleep deprivation (TSD) could influence negatively upon performance, particularly when the task is prolonged and repetitive.
The aim of this study is to examine the influence of TSD on cognitive functioning in a group of firefighters.
Sixty volunteers who were active male fire brigade officers were examined with a computerized battery test that consisted of simple reaction time (SRT) (repeated three times), choice reaction time, visual attention test, and delayed matching to sample. Six series of measurements were undertaken over a period of TSD.
Performance in the second attempt in SRT test was significantly worse in terms of increased number of errors and, consequently, decreased number of correct responses during TSD. In contrast, the choice reaction time number of correct responses as well as the visual attention test reaction time for all and correct responses significantly improved compared to initial time points.
The study has confirmed that subjects committed significantly more errors and, consequently, noted a smaller number of correct responses in the second attempt of SRT test. However, the remaining results showed reversed direction of TSD influence. TSD potentially leads to worse performance in a relatively easy task in a group of firefighters. Errors during repetitive tasks in firefighting routines could potentially translate into catastrophic consequences.
消防员这一职业要求长时间保持高度注意力。然而,完全睡眠剥夺(TSD)可能会对工作表现产生负面影响,尤其是当任务持续时间长且具有重复性时。
本研究旨在探讨TSD对一组消防员认知功能的影响。
对60名现役男性消防队官员志愿者进行了一项计算机化成套测试,该测试包括简单反应时间(SRT)(重复三次)、选择反应时间、视觉注意力测试和延迟样本匹配。在TSD期间进行了六组测量。
在TSD期间,SRT测试第二次尝试时的表现明显变差,错误数量增加,相应地,正确反应数量减少。相比之下,与初始时间点相比,选择反应时间的正确反应数量以及所有正确反应的视觉注意力测试反应时间均显著改善。
该研究证实,在SRT测试的第二次尝试中,受试者犯的错误明显更多,相应地,正确反应数量更少。然而,其余结果显示TSD影响的方向相反。TSD可能导致一组消防员在相对简单的任务中表现更差。消防常规中的重复性任务中的错误可能会转化为灾难性后果。
