Valence-specific effects of oxytocin have been revealed in a selection of preceding studies, while others report that oxytocin could improve facial recognition, regardless of emotion valence. The reported effect was mediated by increased eye gaze during face processing, and attachment style proved to moderate the effect of oxytocin administration on social behavior and cognition. In this study, we used eye tracking to test whether attachment style moderates the effect of oxytocin on negative emotion recognition, which is crucial for social cognition. We employed a placebo-controlled, double-blind, within-participants design. The participants were 73 healthy individuals (41 men) who received a single dose of intranasal oxytocin (24 IU) on one occasion and a placebo dose on another occasion. Visual attention to the eye region was assessed on both occasions, through the completion of an emotion recognition task. Our results showed that oxytocin increased participants' eye gaze towards facial expressions. Among participants who received oxytocin, as opposed to a placebo, only individuals with high attachment anxiety displayed more eye gaze and less mouth gaze towards facial expression, regardless of emotion valence. Our findings confirmed that oxytocin increases gaze to the eye region, thus improving facial recognition, regardless of emotion valence, this relationship was moderated by attachment anxiety. Further, our results highlighted the importance of considering individual differences when evaluating the effects of oxytocin on emotion recognition.

依恋焦虑减轻了催产素对消极情绪识别的影响:来自眼动数据的证据。

一系列先前的研究已经揭示了催产素对价的特异作用,而另一些研究报道说,不论情绪化合价如何,催产素都能改善面部识别。报道的效果是由面部加工过程中视线增加引起的,依恋方式被证明可减轻催产素管理对社交行为和认知的影响。在这项研究中,我们使用眼动追踪测试了依恋风格是否会减轻催产素对负面情绪识别的影响,这对于社会认知至关重要。我们采用了安慰剂控制的双盲参与者内部设计。参与者为73名健康个体(41名男性),他们一次接受一次鼻内催产素(24 IU),另一次接受安慰剂。通过完成情感识别任务,在两种情况下都评估了对眼睛区域的视觉注意力。我们的结果表明催产素增加了参与者对面部表情的视线。在接受催产素(而不是安慰剂)的参与者中,只有情感依恋程度高的人,依恋焦虑高的人对面部表情表现出更多的视线和嘴角。我们的研究结果证实,催产素增加了对眼睛区域的注视,从而改善了面部识别能力,而不论情绪的效价如何,这种关系都因依恋焦虑而得到缓解。此外,我们的结果强调了在评估催产素对情绪识别的影响时考虑个体差异的重要性。我们的结果表明催产素增加了参与者对面部表情的视线。在接受催产素(而不是安慰剂)的参与者中,只有情感依恋程度高的人,依恋焦虑高的人对面部表情表现出更多的视线和嘴角。我们的研究结果证实,催产素增加了对眼睛区域的注视,从而改善了面部识别能力,而不论情绪的效价如何,这种关系都因依恋焦虑而得到缓解。此外,我们的结果强调了在评估催产素对情绪识别的影响时考虑个体差异的重要性。我们的结果表明催产素增加了参与者对面部表情的视线。在接受催产素(而不是安慰剂)的参与者中,只有情感依恋程度高的人,依恋焦虑高的人对面部表情表现出更多的视线和嘴角。我们的研究结果证实,催产素增加了对眼睛区域的注视,从而改善了面部识别能力,而不论情绪的效价如何,这种关系都因依恋焦虑而得到缓解。此外,我们的结果突出了评估催产素对情绪识别的影响时考虑个体差异的重要性。无论情感的效价如何,只有具有高度依恋焦虑的人才会表现出更多的目光凝视和更少的嘴巴凝视面部表情。我们的研究结果证实,催产素增加了对眼睛区域的注视,从而改善了面部识别,无论情感的效价如何,这种关系都因附件焦虑而得到缓解。此外,我们的结果强调了在评估催产素对情绪识别的影响时考虑个体差异的重要性。无论情感的效价如何,只有具有高度依恋焦虑的人才会表现出更多的目光凝视和更少的嘴巴凝视面部表情。我们的研究结果证实,催产素增加了对眼睛区域的注视,从而改善了面部识别能力,而不论情绪的效价如何,这种关系都因依恋焦虑而得到缓解。此外,我们的结果强调了在评估催产素对情绪识别的影响时考虑个体差异的重要性。
