| 摘 要： | 从人的信息处理方式着手探讨脑力负荷产生原因,提取可反映脑力负荷的4个方面指标,然后对分析的工作任务进行逐层分析和归类,用视觉、听觉、认知和运动反应4个信息处理源下的28种行为要素序列进行描述;继而分别从同时进行的行为数、任务难度、同信息源冲突、同处理阶段冲突4个方面指标对行为序列进行评价,以得到操作任务的工作负荷.并以地铁二号线司机宣武门到长椿街段驾驶任务为例研究验证方法的有效性.结果表明,本方法能够描述整个工作过程中脑力负荷的变化情况,并寻找出致使负荷高的原因.

| Abstract: | Research is based on the mental workload multi-resource model of information processing,first picks up four indicators which can reflect the level of mental workload;Then deals with the hierarchical analysis of the tasks carrying out and classifying into 28 behavior parameters of four information resources（Visual、Auditory、Cognitive and Psychomotor）;Further,checks four indicators of task number task difficultconflict of the same information resourceconflict of the same proceeding to evaluation mental workload of the behavior sequence.Finally,validates the effectiveness of this method from evaluating subway operators driving task.Analysis showed that this method can describe the mental workload changes of whole process and find out what cause the high mental workload. |
