Individuals who are high in rejection sensitivity are vigilant toward social cues that signal rejection, and they exhibit attention biases towards information that confirms expectations of rejection. Little is known, however, about the neural correlates of rejection sensitivity. The present study examined whether rejection sensitivity is associated with individuals' neural responses to rejection-relevant information. Female participants, classified as high or average in rejection sensitivity, completed a modified dot-probe task in which a neutral face was paired with either another neutral face or a gaze-averted ("rejecting") face while EEG was collected and ERP components were computed. Behavioral results indicated that average rejection sensitive participants showed an attention bias away from rejecting faces, while high rejection sensitive participants were equally vigilant to neutral and rejecting faces. High rejection sensitivity was associated with ERP components signaling elevated attention and arousal to faces. These findings suggest that rejection sensitivity shapes behavioral and neurocognitive responses to faces.
拒绝敏感性高的个体对表明被拒绝的社交线索保持警惕,并且他们对证实被拒绝预期的信息表现出注意偏向。然而,关于拒绝敏感性的神经关联却知之甚少。本研究考察了拒绝敏感性是否与个体对与拒绝相关信息的神经反应有关。将女性参与者分为拒绝敏感性高或平均水平,她们完成了一项改良的点探测任务,在收集脑电图(EEG)并计算事件相关电位(ERP)成分时,一张中性面孔与另一张中性面孔或一张目光回避(“拒绝”)的面孔配对。行为结果表明,平均拒绝敏感性参与者表现出远离拒绝面孔的注意偏向,而高拒绝敏感性参与者对中性面孔和拒绝面孔同样警惕。高拒绝敏感性与ERP成分相关,这些成分表明对面孔的注意力增强和唤醒水平提高。这些发现表明,拒绝敏感性塑造了对面孔的行为和神经认知反应。
