This study investigated the effects of the menstrual cycle phase on certain components of autonomic arousal and task performance. Premenstrual syndrome (PMS) women and matched controls (non-PMS) were tested both premenstrually and postmenstrually. The conditions selected were a) the presentation of 10 tones, b) a proofreading performance task, and c) a word-association learning task. Skin conductance and heart rate were continuously monitored. No significant effects were found on baseline physiological measures, or on proofreading or word-association performance. A significant point in cycle effect for skin conductance and HR orienting response to the tones was found showing smaller HR and skin conductance responses postmenstrually. Several significant PMS classifications by point in menstrual cycle interactions were found. These indicated that, paradoxically, the non-PMS subjects showed higher spontaneous skin conductance responding during the word association task and higher skin conductance responses to tones prior to menses. While in contrast, PMS subjects yielded higher responding on the same measures postmenstrually. On stress ratings, PMS subjects reported experiencing more stress postmenstrually. Results are discussed in terms of the possible role of expectancy factors and inaccurate self-monitoring.
本研究调查了月经周期阶段对自主神经唤醒的某些成分及任务表现的影响。经前综合征（PMS）女性和匹配的对照组（非PMS）在月经前和月经后均接受了测试。所选择的条件包括：a）呈现10个音调；b）一项校对表现任务；c）一项词语联想学习任务。持续监测皮肤电导和心率。未发现对基线生理指标、校对或词语联想表现有显著影响。发现了月经周期效应在皮肤电导和对音调的心率定向反应方面的一个显著点，表明月经后心率和皮肤电导反应较小。发现了月经周期交互作用中几个显著的经前综合征分类。这些表明，矛盾的是，非PMS受试者在词语联想任务期间表现出较高的自发皮肤电导反应，且在月经前对音调的皮肤电导反应较高。而相比之下，PMS受试者在月经后在相同指标上表现出较高的反应。在压力评分方面，PMS受试者报告在月经后经历了更多压力。从预期因素和不准确的自我监测的可能作用方面对结果进行了讨论。
