警觉性光环境对飞行认知任务表现的影响

从飞行认知任务的主客观表现测试了单色蓝光和3组富蓝多色光对飞行认知任务警觉性水平变化的影响。客观实验评测包括飞行主辅任务测量和信息检视任务测量，分别从计算力及记忆力水平，判断力、寻错力及逻辑力水平，获取4组警觉性光环境下飞行认知任务表现水平的变化情况；主观综合评测通过多维指标的警觉性主观自评量表，运用熵权TOPSIS法建立主观综合评价模型，得到各组光环境下的主观综合评价排序。将主客观的测量结果进行综合分析，结果表明:单色蓝光在飞行主辅任务测量中计算力水平成绩明显高于其他组，4组光环境对记忆力水平均无显著影响；在信息检视任务测量中单色蓝光与富蓝白光对认知表现的提升效应持平，明显高于其他组；整体主观感受方面，富蓝白光综合评价最高。结果可以对驾驶舱警觉性照明设计提供指导。 

Effect of alertness light environment on flight cognitive task performance

The effects of monochromatic blue light and three groups of blue-enriched light on the change of alert level of flight cognitive tasks were tested from the subjective and objective performance of flight cognitive tasks. Objective experimental evaluation, including the measurement of flight main and secondary tasks and information inspection tasks, obtains the changes of the performance level of flight cognitive tasks in four alert light environments from the level of calculation and memory, judgment, error finding and logic. Subjective comprehensive evaluation is based on the alertness subjective evaluation scale of multi-dimensional indicators, the subjective comprehensive evaluation model is established using entropy weight TOPSIS method, and the subjective comprehensive evaluation ranking under each group of light environment is obtained. The results of the subjective and objective measurement were analyzed. The results show that the calculation force level of monochromatic blue light is significantly higher than that of other groups in the measurement of main and secondary missions, and the four groups of light environment have no significant influence on memory level. In the information inspection task measurement, the enhancement effects of monochromatic blue light and blue-enriched white light on cognitive performance are the same, which are significantly higher than those of other groups. In terms of overall subjective feeling, the comprehensive evaluation of blue-enriched white light is the highest, and the results can provide guidance for the design of cockpit warning lighting.
