Recommendations for Mental Workload Measurement in a Test and Evaluation Environment

Abstract

Research performed during the last decade on estimation of mental workload has resulted in a subset of techniques exhibiting global sensitivity. Other techniques have also been demonstrated to have sensitivity in particular applications and can be used for diagnostic purposes. This paper reviews techniques that have shown sufficient sensitivity and robustness to be used in test and evaluation. Topics such as time scale considerations, available documentation, and appropriate procedures are also discussed. Recommendations are then made for workload estimation in test and evaluation situations.
