摘要主观工作量评价在人机系统评价中变得越来越重要。比较了两种流行的方法：(1)主观工作负荷评估技术(SWAT)，它使用联合测量程序来赋予工作负荷评级区间量表属性；(2)NASA正在开发的一种使用单独加权工作负荷得分的技术。这两种方法都被应用于实验室实验，该实验需要对一些单轨和双轨以及空间转换任务进行评级。两种主观评估技术对不同的任务操作表现出相似的敏感性。然而，这两种方法都未能检测到资源竞争对双任务绩效的影响，而且总体上对响应执行加工需求不敏感。这两种技术之间的一个显著区别是，NASA-Bipolal评级始终比SWAT评级的受试者之间的变异性更小。铁饼...
Abstract Assessment of subjective workload is becoming increasingly important in the evaluation of human-machine systems. Two popular methods were compared: (1) the Subjective Workload Assessment Technique (SWAT) that employed a conjoint measurement procedure to confer interval scale properties on the workload ratings, and (2) a technique under development at NASA that used an individually weighted workload score. Both methods were applied in a laboratory experiment that required the rating of a number of single- and dual-tracking and spatial transformation tasks. Both subjective assessment techniques displayed similar sensitivity to the different task manipulations. However, both techniques failed to detect the resource competition effects in the dual-task performance, and were in general insensitive to response execution processing demands. A notable difference between the two techniques was that the NASA-Bipolar ratings consistently had a smaller between-subject variability than the SWAT ratings. Discu...
