摘要
对飞行员心理负荷主观评定方法的特点及局限性进行了总结。认为主观评定比较直接,直显效度高,使用简易,不干扰作业,适用面广,但也存在一些诸如个体差异大、易受生理负荷和短时记忆消退影响等问题。只要选用谨慎,主观评定无疑是飞行员心理负荷评定的重要方法之一。介绍了三种较典型的心理负荷主观评定量表(CH、SWAT、NASA-TLX)。
This paper summarized the advantages and limitations of subjective workload assessmenttechnique for pilots. It is believed that,in comparison with other techniques,subjective assessment tech-nique is somewhat more direct,easier to use,non-intrusive to task,and generally applicable. Neverthe-less,there are some problems in its application such as high variability,liable to be confused with physi-cal workload,and effect by short-term memory decay. It is pointed out that subjective workload assess-poent technique is one of the most important techniques if it is used carefully. Moreover,in this paperthree kinds of subjective workload assessment technique were introduced.
