Parental use of love withdrawal is thought to affect children's later psychological functioning because it creates a link between children's performance and relational consequences. To investigate whether love withdrawal is also associated with the underlying level of basic information processing in the brain, we studied event-related potentials to feedback stimuli that combined performance feedback with emotional facial expressions. We focused on the VPP (face processing) and N400 (incongruence processing). More maternal use of love withdrawal was related to more positive VPP amplitudes, larger effects of the emotional facial expression on VPP amplitude, and more negative N400 responses to incongruent combinations of feedback and facial expressions. Our findings suggest a heightened processing of faces with emotional expressions and greater sensitivity to incongruence between feedback and facial expression in individuals who experienced more love withdrawal.
父母使用爱撤回被认为会影响孩子以后的心理功能，因为它在孩子的表现和关系后果之间建立了联系。为了研究爱撤回是否也与大脑中基本信息处理的基础水平有关，我们研究了与反馈刺激相关的事件相关电位，这些刺激将表现反馈与情绪面部表情结合起来。我们专注于 VPP（面部处理）和 N400（不一致处理）。母亲更多地使用爱撤回与 VPP 振幅的更积极振幅、情绪面部表情对 VPP 振幅的更大影响以及反馈和面部表情不一致组合的更负 N400 反应有关。我们的研究结果表明，在经历更多爱撤回的个体中，对面部表情的处理能力增强，并且对反馈和面部表情之间的不一致性更加敏感。
