Parenting is an essential factor within a child's development, yet the impact of normative variations of parenting on neural emotion processing has not been studied to date. The present study investigated 83 healthy adolescents using functional magnetic resonance imaging and an emotional face-matching paradigm. The faces paradigm elicited an increased amygdala response towards negative facial expressions (fearful and angry each compared to neutral faces) and a significant activation of fusiform gyrus to all emotions separately (fearful, happy, angry faces) compared to neutral faces. Moreover, we investigated associations between neural responses towards emotional faces and mother's parenting behavior (maternal warmth and support, psychological pressure and control behavior). High maternal warmth and support correlated with lower activation to fearful faces in the amygdala. Maternal supportive rather than control behavior seems to have an impact on neural emotion processing, which could also be the key factor for brain functional abnormalities in maltreated children. These results expand existent findings in maltreated children to healthy populations.
养育子女是儿童成长过程中的一个重要因素，但迄今为止，养育方式的规范差异对神经情绪处理的影响尚未得到研究。本研究使用功能磁共振成像和情绪面孔匹配范式对83名健康青少年进行了调查。面孔范式引发杏仁核对负面面部表情（恐惧和愤怒表情分别与中性表情相比）的反应增强，以及梭状回对所有情绪（恐惧、快乐、愤怒表情）与中性表情相比分别有显著激活。此外，我们研究了对情绪面孔的神经反应与母亲养育行为（母亲的温暖与支持、心理压力和控制行为）之间的关联。母亲的高温暖与支持与杏仁核中对恐惧面孔的较低激活相关。母亲的支持性而非控制性的行为似乎对神经情绪处理有影响，这也可能是受虐待儿童脑功能异常的关键因素。这些结果将受虐待儿童的现有研究结果扩展到了健康人群。
