The effects of alterations of the organism's internal state, attributable to the menstrual cycle, upon heart-rate responsivity and conditioning are 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 a conditioning procedure in which a small blue light was the CS and white noise the UCS. Subjects tested premenstrually were significantly differentiated from those tested intermenstrually respecting HR responsivity to the first UCS. Significant differences were also found in conditioned responses following three acquisition trials. The type of reactions observed are similar to those which have been called defensive reactions. Subjects taking the oral contraceptives showed increased susceptibility to acquisition of conditioned responses.
报告了归因于月经周期的机体内部状态改变对心率反应性和条件作用的影响。对两组各24名女性恐惧症患者（一组有自然月经周期，另一组服用口服避孕药）在经前或月经间期进行测试，采用一种条件作用程序，其中小蓝光为条件刺激（CS），白噪声为非条件刺激（UCS）。在对第一个非条件刺激的心率反应性方面，经前测试的受试者与月经间期测试的受试者有显著差异。在三次习得试验后的条件反应中也发现了显著差异。观察到的反应类型与那些被称为防御反应的反应相似。服用口服避孕药的受试者对条件反应的习得表现出更高的易感性。
