Title Portable devices for measuring performance in the field: the effects of sleep deprivation and night shift on the performance of computer operators.
Bibliographic information Aug. 1979, Vol.22, No.8, p.927-933. Illus. 9 ref.
Abstract The performance of 12 computer operators was measured on the job, on 2 new portable tests of reaction time, during the first night of the night shift at 4 a.m. and at the beginning day shift (8 a.m.), over 3 successive 3-week comparisons. Results: mean reaction time increased significantly on the night shift as compared with the day; the adverse effect of the night shift was absent during the first comparison and became increasingly apparent on the second and third replications. Night shift performance was poorer than the day shift and previous studies of sleep deprivation in the laboratory are able to provide a good indication of what was to be expected in the field. The need for longitudinal studies in order to assess the true effects of stressors is emphasised.
