Development of NASA-TLX (Task Load Index): Results of empirical and theoretical research
SG Hart, LE Staveland - Advances in psychology, 1988 - Elsevier
The results of a multi-year research program to identify the factors associated with variations
in subjective workload within and between different types of tasks are reviewed. Subjective
evaluations of 10 workload-related factors were obtained from 16 different experiments. The
experimental tasks included simple cognitive and manual control tasks, complex laboratory
and supervisory control tasks, and aircraft simulation. Task-, behavior-, and subject-related
correlates of subjective workload experiences varied as a function of difficulty manipulations …
