Abstract : In order to evaluate the impact of thermal and physical stress on mission-related performance in a quantifiable fashion, and to develop a technology to minimize the effects of such stresses, it has become important to develop standardized measures of mission-related performance. The present report presents fundamental information relating to the selection of measures to assess the impact of operational stressors on cognitive performance. The initial cognitive performance abilities presently considered and adopted for standardized measurement in thermally and physically stressful operational environments are: memory, reaction time, vigilance, calculations, logical reasoning, and learning. The six currently adopted measures of cognitive performance are matching-to-sample, complex reaction time, visual vigilance, serial addition-subtraction, logical reasoning, and repeated acquisition. The measures have been implemented in a standardized manner on portable battery-operated computers for use in both laboratory and field settings. The report provides detailed documentation for each of the measures, including computer code listings.
