Abstract： 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: Sternberg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<0.05). 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据. 通过难度等级不同的行为作业可以作为情绪的诱导情境.
