Abstract : The objective of this paper is to provide information about circadian rhythms and their relevance to the development of models of human cognitive performance. Circadian rhythms are well-established characteristics of human performance. However, to date, models of human performance generally have not taken them into account. The general effects of circadian rhythms will be reviewed, followed by a discussion of the interaction of sustained operations (SUSOPS) and jet lag with these rhythms. Individual differences in circadian rhythms will be addressed, and some published circadian rhythm models will be discussed. While physiological aspects of performance also show circadian rhythms, fluctuations in cognitive performance are more pronounced and will be the focus of this report.
