与月经周期相关的雌激素变化预计会对各种认知测试产生不同的影响。具体而言，雌激素峰值发生在排卵期妇女的中期，预计将促进高度实践的自动化任务的性能和损害性能的感知重建任务，与这些任务的性能在排卵后阶段的周期时，孕激素被认为是抵消雌激素的作用。感知重构任务是指对明显刺激属性的初始感知是错误的，必须将其放在一边，以利于对不太明显的刺激属性的感知。我们研究了87名定期进修的女大学生。奇数受试者首先在其周期的第10天或第10天左右进行测试，然后在第20天再次进行测试;偶数受试者以相反的顺序进行测试。每日记录基础体温。这些体温记录表明，21例或24%的受试者在研究的周期中没有排卵。在66名确实出现排卵的妇女中，任何任务都没有发生第10天与第20天的主要影响。预测的性能变化的幅度与接近第10天测试日的基础体温记录的热最低点，推测排卵前雌激素峰值;和第20天接近基础体温热峰值，推测孕酮峰值显着相关。受试者在热最低点前3天或更短时间内以及在热峰值时或之后进行测试，在4项管理任务中的3项上具有预测的显著变化。没有其他时间定义的组产生显著变化。精确的计时对于演示这些现象至关重要。
Menstrual-cycle-related changes in estrogen were expected to differentially affect various cognitive tests. Specifically, the estrogen peak occurring at midcycle in ovulatory women was expected to facilitate performance of highly practiced automatized tasks and to impair performance of perceptual-restructuring tasks, compared with performance of these tasks in the postovulatory phase of the cycle when progesterone is thought to counteract the action of estrogen. Perceptual-restructuring tasks are defined as tasks in which the initial percepts to obvious stimulus attributes are wrong and must be set aside in favor of percepts to less obvious stimulus attributes. Regularly menstruating undergraduate women (87) wre studied. Odd-numbered subjects were tested first on or about day 10 of their cycle and then again on day 20; even-numbered subjects, in the reverse sequence. Daily basal body temperature records were obtained. These temperature records suggested that 21, or 24%, of the subjects did not ovulate in the cycle studied. No main effect of day 10 vs. day 20 occurred for any task in the 66 women who did appear to ovulate. The magnitude of predicted shifts in performance was significantly correlated with proximity of the day 10 testing day to the thermal nadir of the basal body temperature record, the presumed preovulatory estrogen peak; and to the day 20 proximity to the basal body temperature thermal peak, the presumed progesterone peak. Subjects tested 3 or fewer days before the thermal nadir and on or after the thermal peak had the predicted significant changes on 3 of the 4 administered tasks. No other temporally defined group produced significant changes. Precise timing is essential to demonstrate the phenomena.
