月经周期、产后和更年期期间的生理荷尔蒙波动与情绪、认知和情感障碍的调节有关。考虑到女性在记忆任务中的表现也会随着月经周期中循环激素水平的变化而波动，因此使用六种基本情绪作为延迟匹配样本的刺激，评估了年轻女性在月经周期不同阶段的情绪面部表情工作记忆任务中的认知表现。我们的研究结果表明，卵泡期高水平的雌二醇可能会对使用情绪效价刺激的延迟匹配样本工作记忆任务产生负面影响。此外，在卵泡期，与月经期相比，悲伤和厌恶等情感面部表情的错误百分比明显更高。对每种具有情绪效价的面部表情的反应时间（用于回答的时间）的评估显示，在涉及悲伤的情绪面部表情方面，卵泡和黄体之间存在显着差异。我们的结果表明，卵泡期高水平的雌二醇可能会损害工作记忆的表现。然而，这种效应特定于选择性面部表情，表明在怀孕风险较高的月经周期阶段，女性可能不太重视对悲伤和厌恶等情感面部表情的识别。这项研究与对非人类灵长类动物进行的研究一致，表明月经周期中卵巢激素的波动会影响各种社会和认知行为。此外，我们的数据也可以代表一个有用的工具。用于调查与女性月经周期阶段和更年期有关的情绪障碍。 (c) 2008 Elsevier Ltd. 保留所有权利。
Physiological hormonal fluctuations during the menstrual cycle, postpartum, and menopause have been implicated in the modulation of mood, cognition, and affective disorders. Taking into account that women's performance in memory tasks can also fluctuate with circulating hormones levels across the menstrual cycle, the cognitive performance in a working memory task for emotional facial expressions, using the six basic emotions as stimuli in the delayed matching-to-sample, was evaluated in young women in different phases of the menstrual cycle. Our findings suggest that high levels of estradiol in the follicular phase could have a negative effect on delayed matching-to-sample working memory task, using stimuli with emotional valence. Moreover, in the follicular phase, compared to the menstrual phase, the percent of errors was significantly higher for the emotional facial expressions of sadness and disgust. The evaluation of the response times (time employed to answer) for each facial expression with emotional valence showed a significant difference between follicular and luteal in reference to the emotional facial expression of sadness. Our results show that high levels of estradiol in the follicular phase could impair the performance of working memory. However, this effect is specific to selective facial expressions suggesting that, across the phases of the menstrual cycle, in which conception risk is high, women could give less importance to the recognition of the emotional facial expressions of sadness and disgust. This study is in agreement with research conducted on non-human primates, showing that fluctuations of ovarian hormones across the menstrual cycle influence a variety of social and cognitive behaviors. Moreover, our data could also represent a useful tool. for investigating emotional disturbances Linked to menstrual cycle phases and menopause in women. (c) 2008 Elsevier Ltd. All rights reserved.
