先前的研究表明，催产素改善了面部表情的编码和识别，这被认为是通过在面部处理过程中增加对眼睛区域的探索来介导的。在本研究中，我们使用眼动追踪来评估眼睛区域的视觉注意力，而参与者进行动态面部情绪识别任务。在一项双盲、安慰剂对照的受试者间设计中，参与者接受24 IU鼻内催产素（n = 23）或安慰剂（n = 24）。虽然催产素对参与者对情绪面孔的视觉扫描没有影响，但它通常会增强识别性能，因为催产素组在较低强度水平下识别情绪表达。这些研究结果表明，催产素诱导的面部情绪识别的改善是独立的调制在公开的视觉注意。(C)2011爱思唯尔有限公司保留所有权利。
Previous studies have shown that oxytocin improves the encoding and recognition of facial expressions, which has been proposed to be mediated by an increased exploration of the eye region during face processing. In the present study, we used eye tracking to assess visual attention to the eye region while participants performed a dynamic facial emotion recognition task. In a double-blind, placebo-controlled between-subjects design participants received 24 IU intranasal oxytocin (n = 23) or a placebo (n = 24). Although oxytocin administration had no effect on participants' visual scanning of emotional faces, it generally enhanced recognition performance, as the oxytocin group recognized emotional expressions at lower intensity levels. These findings suggest that oxytocin-induced improvement of facial emotion recognition is independent of modulations in overt visual attention. (C) 2011 Elsevier Ltd. All rights reserved.
