The present electrophysiological study investigated the role of the need for cognitive closure (NFC) in emotional processing. The NFC is conceptualized as an epistemic motive that is related to how and why people seek out information in social environments. Event-related potentials were recorded while individuals with high NFC (i.e., low epistemic motivation) or low NFC (i.e., high epistemic motivation) performed a modified Ultimatum Game, in which the emotions of happy or angry game agents were employed to predict their most likely offer. High-NFC participants more closely adhered to the decisions rules of the game than low-NFC individuals did. The electrophysiological results showed that the dispositional NFC modified early perceptual components (N170, N200, and P200). The potentials showed that high-NFC subjects had a processing bias to angry faces, whereas low-NFC individuals exhibited no such effects. These findings indicated that high-NFC individuals were more sensitive to negative emotional stimuli than low-NFC individuals in an interpersonal decision-making task.
本电生理研究调查了认知闭合需求（NFC）在情绪加工中的作用。NFC被概念化为一种认知动机，它与人们在社会环境中寻求信息的方式和原因有关。在高NFC（即低认知动机）或低NFC（即高认知动机）个体进行改良版最后通牒博弈时记录事件相关电位，其中利用快乐或愤怒的博弈参与者的情绪来预测他们最可能给出的提议。高NFC参与者比低NFC个体更严格地遵守博弈的决策规则。电生理结果表明，特质性NFC改变了早期感知成分（N170、N200和P200）。这些电位显示，高NFC受试者对愤怒面孔存在加工偏向，而低NFC个体则未表现出此类效应。这些发现表明，在人际决策任务中，高NFC个体比低NFC个体对负面情绪刺激更敏感。
