月经周期和神经质对高兴和恐惧表情识别的影响(英文)

Effect of the Menstrual Cycle and Neuroticism on Fearful and Happy Faces Recognition

目的:探索不同神经质水平女性在月经周期中对高兴和恐惧面孔的识别绩效及其与卵巢激素之间的关系。方法:让高、低神经质两组女性在卵泡早期,卵泡晚期和黄体期对不同强度的恐惧和高兴面孔进行识别,并对卵巢激素进行检测。结果:面孔表情识别的正确率在晚卵泡期高于卵泡早期或黄体期,但是没有达到统计显著性。高低神经质组之间没有发现显著差异。此外,男性和高兴面孔识别的正确率更高,反应速度也更快。面孔表情与性别交互作用表明只有在女性面孔上,高兴识别的正确率显著高于恐惧识别的正确率。而男性高兴面孔识别的正确率与雌激素和黄体酮水平均显著负相关,睾酮与面孔识别的反应时相关显著,泌乳素仅与高兴面孔识别的正确率显著负相关。结论:月经周期中面孔表情识别绩效与卵巢激素相关,尤其是雌激素、黄体酮、睾酮和泌乳素可能是影响面孔表情加工的潜在内分泌机制。

Objective： To assess the effect of the menstrual cycle and neuroticism on fearful and happy faces recognition. Methods： High and low neuroticism females were asked to recognize fearful and happy faces with different intensity during early follicular phase, late follicular phase and the luteal phase, with the ovarian hormones tested meanwhile. Results： More accuracy and faster responses for male and happy faces were found. The interaction between emotion and gender of faces showed only for female faces, better accuracy were found in happiness recognition than in fear recognition.More importantly, estrogen and progesterone levels were both negatively correlated with perception of male happy faces, and prolactin was also negatively correlatd with happy faces. Furthermore, significant correlations between reaction time for all faces and testosterone were found. Conclusion： The results suggest emotion face recognition performances are associated with ovarian hormones, especially estrogen, progesterone, testosterone and prolactin, which may be the potential endocrine mechanism to affect face expression recognition.
