表情对婴儿面孔图式效应的调节及其机制

婴儿面孔图式效应是促进早期亲子关系形成的一种先天本能反应, 该效应一直被认为主要是受婴儿面孔结构的影响。但近年来表情对该效应的影响开始得到关注, 在以成人面孔为基线的条件下, 婴儿面孔图式效应量会因表情不同而有所变化, 表现出中性婴儿面孔图式效应最强的现象。鉴于目前对该现象的成因及其神经机制知之甚少, 所以本项目拟先建立一套婴儿与成人同面孔多表情图片系统; 然后以此为基础, 分别考察面孔表情不确定性是否会调节成人对不同表情婴儿面孔的偏好和注意偏向, 并探究其相应神经机制, 促进养育脑研究在我国的开展。

Moderating effects of facial expression on the babyface schema and its neural mechanism

The effect of the babyface schema is an innate instinct that promotes the formation of early parent-child relationships; this has been thought to be primarily influenced by the baby's face structure. However, in recent years, the influence of facial expression on this effect has begun to attract attention. With the adult face as the baseline, the size of the babyface schema’s effect will change with different facial expressions, and the effect of a neutral babyface schema becomes the strongest. Because the cause of this phenomenon and its neurological mechanism are still unclear, this project first plans to establish a set of standardized facial pictures of an infant and adult displaying various affective faces. Then, based on this, the researchers will investigate whether facial expression uncertainty can moderate adults’ preferences and attention biases for infants with different facial expressions, and they will furthermore explore the corresponding neurological mechanism to promote research on the parental brain in China.
