Long Workdays versus Restdays: Assessing Fatigue and Alertness with a Portable Performance Battery
研究用一套便携式心理行为测试组比较了连续五天每天12小时的数据录入工作与休息日，发现工作期间语法推理变快但准确率下降、数字加法变慢、反应时变长、手部稳定性降低，表明该测试能有效检测长时间工作的疲劳效应。
A test battery designed to assess psychological/behavioral fatigue was used to compare restdays to a workweek of five 12-hr days at a data entry job simulation. Across both workdays and restdays, the battery was presented at regular intervals to test for fatigue effects and diurnal variations. Increased data entry errors across the workday and the workweek as well as subjective reports of increased tiredness on workdays indicated that the work regimen was fatiguing. Test battery performance paralleled those results. On workdays, as compared with restdays, grammatical reasoning was faster but less accurate; digit addition was slower; simple, dual, and choice reaction times were slower; and hand steadiness decreased. The results demonstrated the sensitivity of the battery to long hours of work. The results are discussed in terms of work-rest differences, changes across the workweek, diurnal variations, and cognitive demand.
