The origin of the NASA Task Load Index, the most widely used subjective workload instrument. Reports a multi-year NASA-Ames program (247 subjects, 16 experiments) that reduced ten candidate workload factors to six subscales — Mental Demand, Physical Demand, Temporal Demand, Performance, Effort, Frustration — combined into an overall score via importance weights obtained by pairwise comparison. Already cited as a secondary reference in the existing `mental-workload` article (Hancock et al. 2021 chapter); now held in RAW.
