这项研究调查了对面部表情的敏感性和评价是否会随着短时间重复接触非典型面部表情而发生变化。一种变形的面部表情被重复呈现500ms，参与者被要求指出每个面部表情是高兴还是愤怒。我们操纵了每个面部刺激的变形面部表情的呈现分布。在面部刺激中描绘的一些人经常表达愤怒(即，容易生气的人)，而另一些人经常表达快乐(即，倾向于快乐的人)。在接触到容易发怒的人的脸后，参与者对这些人的愤怒脸变得不那么敏感。此外，在接触到有快乐倾向的人的脸后，参与者对这些人的快乐脸变得不那么敏感。我们还发现，在接触面部刺激后，倾向于快乐的人的社交愿望相对增加。
This study investigated whether sensitivity to and evaluation of facial expressions varied with repeated exposure to non-prototypical facial expressions for a short presentation time. A morphed facial expression was presented for 500 ms repeatedly, and participants were required to indicate whether each facial expression was happy or angry. We manipulated the distribution of presentations of the morphed facial expressions for each facial stimulus. Some of the individuals depicted in the facial stimuli expressed anger frequently (i.e., anger-prone individuals), while the others expressed happiness frequently (i.e., happiness-prone individuals). After being exposed to the faces of anger-prone individuals, the participants became less sensitive to those individuals' angry faces. Further, after being exposed to the faces of happiness-prone individuals, the participants became less sensitive to those individuals' happy faces. We also found a relative increase in the social desirability of happiness-prone individuals after exposure to the facial stimuli.
