Previous research has shown that the addition of happy or angry expressions to other-race faces can assist infants in overcoming the perceptual narrowing of face race and reinstating their recognition of other-race faces. In the present study, we examined how different facial expressions (happy, angry, fearful, and neutral) influence the recognition of African faces among Chinese infants aged 8 to 12 months. We employed a visual familiarization task and measured infants' looking time. The results revealed that infants exhibited above-chance discrimination of African faces in the happy and angry conditions, but not in the neutral or fearful conditions. The findings suggest that not all facial expressions have a uniform effect on infants' ability to recognize faces of other races.
先前的研究表明，在其他种族的面孔上添加开心或愤怒的表情可以帮助婴儿克服对面孔种族的感知狭窄，并恢复他们对其他种族面孔的识别能力。在本研究中，我们考察了不同的面部表情（开心、愤怒、恐惧和中性）如何影响8至12个月大的中国婴儿对非洲面孔的识别。我们采用了视觉熟悉任务，并测量了婴儿的注视时间。结果显示，婴儿在开心和愤怒条件下对非洲面孔表现出高于随机水平的辨别能力，但在中性或恐惧条件下则不然。这些发现表明，并非所有面部表情对婴儿识别其他种族面孔的能力都有一致的影响。
