摘要
目的分析连续驾驶任务构建的脑力疲劳状态下的情绪变化特点,以期为军队驾驶员今后合理的工作和休息制度提供理论基础,从而预防工作中负性情绪所导致的各种不良事件的出现。方法应用疲劳量表(Fatigue scale-14)、简明心境量表(Profile of Mood States,POMS)以及视觉类比量表(Visual Analogue Scales,VAS)对120名连续7 h驾驶的被试者进行测试,以评价任务前后被试的疲劳状态,及探讨脑力疲劳对于情绪的影响。结果疲劳量表结果表明被试表现出疲劳状态,疲劳总分、躯体疲劳和脑力疲劳因子分均在任务后明显增高。从POMS量表结果可见,被试组在驾驶后有三个因子即紧张-焦虑(T)、愤怒-敌意(A)和疲乏-惰性(F)分值增高。VAS测验的结果表明被试疲劳前后,在"警觉/能够集中注意"、"焦虑"和"易怒"这三类指标上,分数可见明显差异。结论持续的驾驶操作使得驾驶人员产生疲劳,从而影响任务操作者的情绪。在连续工作一定时间后,不良情绪可能会影响到驾驶员的工作状态,适时休息是缓解军队驾驶人员疲劳状态及保证情绪稳定的重要措施。
Objective To analyze the characteristics of emotion changes with driving fatigue,provide theoretical basis of reasonable work and rest schedules,and thus to prevent adverse events caused by negative emotions in army drivers.Methods Fatigue Scale- 14,Profile of Mood States（ POMS） and Visual Analogue Scale（ VAS） were used to investigate120 subjects,who completed continuing driving for 7 hours. The mental fatigue states before and after the tasks,as well as the influences on emotion caused by mind fatigue were evaluated and discussed. Results The total fatigue score,mental fatigue score and physical fatigue all were statistically higher after task than that before the task（ all P〈 0. 05）.The scores of three factors of POMS,namely Anxiety- Tension（ T）,Anger- Hostility（ A） and Fatigue- Inertia（ F）,were all statistically increased after continuing driving. So was the case in the scores of three factors in VAS,including＂alertness/ability to focus＂,＂anxiety＂,and＂irritability＂. Conclusion Fatigue could be generated in drivers after continuing tasks,and their emotions could be affected. When worked continually for some time,negative emotions may influence work efficiency. Reasonable rest can be an important way to reduce the fatigue,and ensure emotions＇ stability.
