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 p...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.
