Hancock, P.A., Vercruyssen, M., & Rodenberg, G. (1992). The effect of gender and time-of-day on time perception and mental workload. Current Psychology: Research and Reviews, 11, 203-225.

Two experiments investigated how S gender and time of day influenced the estimation of duration and the perception of task-related mental workload. In Exp 1, 24 Ss (aged 21–40 yrs) performed a filled time-estimation task (TTK) in a constant blacked-out, noise-reduced environment at 0800, 1200, 1600, and 2000 hr. In Exp 2, 12 different Ss performed an unfilled TTK in similar conditions at 0900, 1400, and 1900 hr. All participants completed a workload assessment questionnaire as a measure of perceived mental workload. Results indicated that physiological response, reflected in body temperature change, followed an expected pattern of sequential increase with time of day. In each of the experiments there were significant differences in time estimation and mental workload response contingent on the gender of the participant.
