An experiment on mood changes in relation to the premenstrual phase of the cycle is reported. Two groups of 24 female phobic patients (one with natural cycles and the other taking the oral contraceptive) were tested either premenstrually or intermenstrually using concurrent and retrospective methods of mood assessment. Although subjects retrospectively reported experiencing negative mood changes during the premenstrual phase as compared to the intermenstrual phase, no such differences were found when subjects were tested at these particular phases when the purpose of the study was disguised. The implication of this finding, together with those reported previously concerning conditionability and defensive reactions, are discussed.
本文报告了一项关于月经周期前阶段情绪变化的实验。两组各24名女性恐惧症患者（一组月经周期正常，另一组服用口服避孕药），分别在经前或经间期使用同步和回顾性情绪评估方法进行测试。尽管受试者回顾性报告称，与经间期相比，经前阶段经历了负面情绪变化，但当研究目的被掩盖时，在这些特定阶段对受试者进行测试时，未发现此类差异。本文讨论了这一发现的意义，以及先前报道的关于条件反射和防御反应的研究结果。
