摘　　要：本研究通过两个实验,分别对被试从事监控任务和追踪任务时的心理负荷进行测量,从而考察了几种测量指标的变化规律,结果发现,把主观任务难度作为联系两个不同任务的因子,对两个任务各心理负荷测量作综合分析,多数指标变化随负荷程度呈有规律的趋势。(1)主任务测量评价主任务是否超负荷较为有效,而对于非超负荷任务的负荷变化,辅助作业测量较为敏感。(2)心率和血压变化与心理负荷呈近似倒 U 型关系。A 型行为模式个体的心率变化与别的个体的心率变化存在着实质性的模式差异。The operators' mental workload in monitoring and tracking tasks was measured in two experiments to compare different indices for evaluating mental workload.The results indicated that primary task performance was a sensitive measurement for task overload.For non-overload task,secondary task measurement was a sensitive index for evaluating operator's mental workload.The curves reflecting the relations between heart rate and mental workload,and between blood pressure and mental work load were in appro- ximately invert-U forms.The pattern of heart rate change of subjects with Type A Behavior was significantly different from others.
