Abstract:

This monograph examines the magnitude of circadian effects on selected information processing tasks. The monograph begins with a brief discussion of the statistical and methodological problems associated with assessing circadian effects. The remainder of the monograph reviews the pertinent literature. Each study is described briefly first and critically examined from a methodological standpoint. Then, the maximum and minimum circadian effects are presented as a percentage of mean performance to allow the results to be compared across studies. Approximately half of the statistical tests conducted to detect circadian effects were nonsignificant. The majority of circadian effects, regardless of their statistical significance, showed less than a 10 difference between mean performance and either the maximum or minimum performance.
