【摘要】：目的 :通过难度递增式Sternberg双重任务作业诱导被试的情绪反应 ,考查不同难度测验中个体作业绩效与情绪稳定性和心率变异性 (HRV)的关系 ,探讨情绪情境诱导方式 .方法 :89名飞行学员分别完成 3个不同难度等级的Sternberg双重任务作业 ,同时记录心电信号 ,分析时域及频域HRV .Sternberg双重任务作业主任务为跟踪作业 ,副任务为选择反应时作业 .根据选择反应的难度 ,副任务分为 3个等级 .在被试者进行飞行训练时 ,由飞行教员用“飞行学员情绪稳定性效标评价量表”对其情绪稳定性进行评价 .此外 ,用招飞基本能力成绩作为飞行基本能力 .分析Sternberg双重任务作业成绩、飞行基本能力、情绪稳定性以及HRV的关系 .结果 :Stern berg双重任务作业成绩好组与作业成绩差组基本能力无显著性差别 .无论是何种难度水平 ,作业成绩好组较作业成绩差组在效标评定得分上均较小 ,在难度 3水平上 ,两组效标达到统计学显著水平 (P 0 .0 5 ) .在 3种难度等级上 ,作业成绩好组均表现为较小的HRV低频功率、高频功率、RR间期标准差、RR间期差值均方根、低高频功率比及心率 ,指标的变化趋势有着较好的一致性 .结论 :作业成绩与个体情绪稳定性间有着某种内在联系 ,个体情绪的稳定程度影响着认知作业的成绩 ,且具有一定的生理依
[Abstract]:Objective: to investigate the relationship between individual task performance and emotional stability and heart rate variability (HRV) in different difficulty tests by inducing emotional response in subjects with increasing difficulty of Sternberg task. Methods #number0# flight cadets completed three Sternberg tasks of different degree of difficulty, and recorded ECG signals at the same time. The dual task of HRV Sternberg in time domain and frequency domain was analyzed. The owner's task was tracking, and the secondary task was selective reaction time. According to the difficulty of selecting reaction, the secondary task was divided into three grades. The students' emotional stability was evaluated by flight instructor with the scale of evaluation of emotional stability of flight cadets. In addition, the basic ability of recruiting and flying was used as the basic ability of flight. The results of Sternberg dual task operation were analyzed. Results there was no significant difference in basic abilities between the two task performance groups: the basic abilities of the two groups. No matter the level of difficulty, there was no significant difference between the two groups. In the difficulty level 3, the two groups reached the statistical significant level (P 0. 05). In the 3 difficulty levels, the scores of the two groups were lower than those of the poor group. The scores of the two groups reached the level of statistical significance (P 0. 0. 05), and the scores of the two groups were significantly lower than those of the poor group. The low HRV low frequency power, high frequency power and RR interval difference mean square root, low high frequency power ratio and heart rate were all shown in the good performance group. Conclusion: there is some internal relation between the achievement of work and the stability of individual emotion. The degree of stability of individual emotion affects the achievement of cognitive work and has certain physiological dependence.
