Fifty-four participants took part in a study to evaluate the effects of the menstrual cycle on mood and the performance of a perceptual-motor task. The task involved tracking a randomly-moving circle on a computer screen with a joystick-controlled dot. Women were tested on three occasions, during the premenstrual, menstrual and ovulatory phases. Each testing session involved completing the Menstrual Distress Questionnaire, the monopolar Profile of Mood States questionnaire and performing five, timed trials on the task. A control group of male participants completed the Profile of Mood States questionnaire on three separate occasions over 28 days according to a pseudo-menstrual cycle experimental protocol. Results revealed that females experienced low energy and impaired cognitive function, both premenstrually and during menstruation. Task performance did not vary with menstrual-cycle phase, suggesting that they either tried to compensate for a lack of well being, or that negative mood was of insufficient magnitude to manifest a performance change. The findings suggest that when the purpose of an assessment is disguised, typically-reported menstrual-cycle and mood-related effects on performance are not observed reliably.
54名参与者参与了一项研究，以评估月经周期对情绪以及一项感知运动任务表现的影响。该任务包括用操纵杆控制的点在电脑屏幕上跟踪一个随机移动的圆圈。女性在经前、经期和排卵期三个阶段接受测试。每次测试都包括完成月经困扰问卷、单极情绪状态剖面图问卷，并在该任务上进行五次定时试验。一组男性参与者作为对照组，根据一个模拟月经周期的实验方案，在28天内分三次单独完成情绪状态剖面图问卷。结果显示，女性在经前和经期都出现精力不足和认知功能受损的情况。任务表现并未随月经周期阶段而变化，这表明她们要么试图弥补身体不适，要么负面情绪的程度不足以导致表现发生变化。研究结果表明，当评估目的被掩饰时，通常所报告的月经周期和情绪对表现的影响并不能被可靠地观察到。
