摘　　要：次任务测定技术是心理负荷评定的重要方法之一,它是以“有限无差异加工资源”假设为基础提出的,这一技术存在“侵入性”、“难度不敏感性”及“结构特异性”等问题,在实际情境中进行测评有时有一定的危险,但是,它具有其它测定技术不具备的“诊断性”特点,作者认为,只要次任务选择适当,次任务测定技术在评定心理负荷中的效用仍是十分明显的.The subsidiary task technique is one of the most common techniques in assessing men-tal workload.It is based on the limited-and undifferentiated-capacity resources hypothe-sis.There are some problems associated with it such as intrusiveness,difficulty insensitivity,structural specificity and potential hazard of applicaton to real situation.However,it pos-sessed diagonostic which all other techniques do not.We think that the subsidiary tasktechnique has an evident utility in assessing mental workload so long as we select subsidiarytask properly.
