自发侵入性回忆（SIRS）是已知的临床和非临床人群中的情绪事件。我们实验室以前的工作发现，女性在接触情感电影后比男性报告更多的SIR，并且这种影响完全是由处于月经周期黄体期的女性驱动的。为了复制和扩展这一发现，参与者观看了情感电影，提供了唾液样本进行性激素浓度分析，并估计了电影观看后的SIR频率。在黄体期的妇女比在卵泡期的妇女报告了更多的SIR，SIR频率与唾液孕酮水平显著相关。研究结果与文献中的一种新模式一致，表明女性参与者的月经周期位置可以有力地影响许多认知领域的研究结果。这些结果的潜在影响，为特征的入侵，如创伤后应激障碍，也进行了讨论。(C)2011 Elsevier Inc.

Spontaneous intrusive recollections (SIRS) are known to follow emotional events in clinical and non-clinical populations. Previous work in our lab has found that women report more SIRs than men after exposure to emotional films, and that this effect is driven entirely by women in the luteal phase of the menstrual cycle. To replicate and extend this finding, participants viewed emotional films, provided saliva samples for sex hormone concentration analysis, and estimated SIR frequency following film viewing. Women in the luteal phase reported significantly more SIRs than did women in the follicular phase, and SIR frequency significantly correlated with salivary progesterone levels. The results are consistent with an emerging pattern in the literature suggesting that menstrual cycle position of female participants can potently influence findings in numerous cognitive domains. The potential implications of these results for disorders characterized by intrusions, such as post-traumatic stress disorder, are also discussed. (C) 2011 Elsevier Inc. All rights reserved.
