With multiple tasks to complete throughout the day, it would be helpful to know the peak circadian timing for performance on each task. However, the literature on task dependence in circadian rhythms of performance is mixed. We investigated this issue by comparing three neurobehavioral tests administered every 2 hours through a 24-hour constant routine protocol, which was preceded by 3 days of either a night shift or a day shift schedule—a design that separated the homeostatic and circadian processes and exposed the endogenous circadian rhythm of neurobehavioral functioning. Accounting also for individual differences, we found that the circadian peak time did not differ significantly between tests. Thus, we found no evidence that a person’s endogenous circadian timing for optimal neurobehavioral functioning is inherently task-dependent.
