母乳喂养行为可以显著改变母亲的生理和心理状态。荷尔蒙催产素可能调节母乳喂养和母亲的情绪识别。本研究考察了51位初产母亲在母乳喂养过程中内源性催产素波动对情绪识别的影响。在操作（母乳喂养或抱着婴儿）前后评估唾液催产素，并进行情绪识别任务。在每天母乳喂养的母亲中，母乳喂养后催产素水平增加的母亲对成人面部表情的负面识别能力更低，积极识别能力更强。这些伴随着母乳喂养的催产素功能可能支持持续的养育行为，也会影响其他成年人的一般社会认知，而不是对婴儿的任何特定影响。
Breastfeeding behaviours can significantly change mothers' physiological and psychological states. The hormone oxytocin may mediate breastfeeding and mothers' emotion recognition. This study examined the effects of endogenous oxytocin fluctuation via breastfeeding on emotion recognition in 51 primiparous mothers. Saliva oxytocin was assessed before and after the manipulation (breastfeeding or holding an infant), and emotion recognition tasks were conducted. Among mothers who breastfed daily, mothers with more increased levels of oxytocin after breastfeeding showed more reduced negative recognition and enhanced positive recognition of adult facial expressions. These oxytocin functions accompanying breastfeeding may support continued nurturing behaviours and also affect the general social cognition of other adults beyond any specific effect on infants.
