21 women with spontaneous ovulatory menstrual cycles, and 7 women who were regular users of oral contraceptives were investigated over two consecutive menstrual cycles. There two groups were compared on their two flash threshold performance and on mood ratings. It was found that, for women with ovulatory menstrual cycles, visual sensitivity was enhanced during the late follicular phase of the cycle, as ovulation approached. At other phases of the menstrual cycle (paramenstrual and luteal) visual sensitivity remained constant and comparable to the values found in women who were taking to the values found in women who were taking contraceptives. Women who were taking contraceptives showed no significant variation in visual sensitivity with phase of the menstrual cycle. The overall level of anxiety, as reflected by mood ratings was higher in women with spontaneous cycles compared to those taking contraceptives. Neither group, however, showed significant variation in anxiety with phase of the cycle.
对21名月经周期自然排卵的女性和7名长期服用口服避孕药的女性进行了连续两个月经周期的调查。比较了这两组女性的两个闪光阈值表现和情绪评分。结果发现，对于月经周期自然排卵的女性，在卵泡期晚期，随着排卵临近，视觉敏感度会增强。在月经周期的其他阶段（经前期和黄体期），视觉敏感度保持恒定，与服用避孕药的女性的数值相当。服用避孕药的女性视觉敏感度在月经周期各阶段无显著变化。情绪评分所反映的焦虑总体水平，自然周期的女性高于服用避孕药的女性。然而，两组在焦虑水平上均未随月经周期阶段出现显著变化。
