Seventy-nine 3-year olds and their mothers participated in a laboratory-based task to assess maternal hostility. Mothers also reported their behavioral regulation of their child. Seven years later, functional magnetic resonance imaging data were acquired while viewing emotional faces and completing a reward processing task. Maternal hostility predicted more negative amygdala connectivity during exposure to sad relative to neutral faces with frontal and parietal regions as well as more negative left ventral striatal connectivity during monetary gain relative to loss feedback with the right posterior orbital frontal cortex and right inferior frontal gyrus. In contrast, maternal regulation predicted enhanced cingulo-frontal connectivity during monetary gain relative to loss feedback. Results suggest parenting is associated with alterations in emotion and reward processing circuitry 7-8 years later.
79 名 3 岁儿童及其母亲参与了一项基于实验室的任务,以评估母亲的敌意。母亲们还报告了他们对孩子的行为调节情况。七年后,当他们观看情绪面孔并完成奖励处理任务时,采集了功能性磁共振成像数据。与观看中性面孔相比,母亲的敌意预测了在观看悲伤面孔时杏仁核连接的负性增加,与损失反馈相比,在获得金钱奖励时预测了左侧腹侧纹状体连接的负性增加,这种连接涉及额叶和顶叶区域以及眶额后皮质和下额前回的右侧。相反,母亲的调节预测了在获得金钱奖励时与损失反馈相比扣带回-前额叶连接的增强。结果表明,养育方式与 7-8 年后的情绪和奖励处理回路的改变有关。
