面孔可信任度评价的研究回顾

摘要

面孔可信任度评价是人际交往中一种重要的特质推断，它直接决定个体在人际互动中采取接近还是回避的反应，是社会互动的门控机制，具有重要的生存适应和个体保护意义。研究表明，面孔可信任度评价类似于效价判断，发生在刺激呈现后100 ms以内。近年来，研究者采用功能性磁共振成像技术发现，当让被试对面孔进行可信任度评价时，杏仁核、眶额叶、右侧脑岛等脑区被激活。既往研究在研究内容、研究材料等方面尚存不足，这正是今后的研究方向。%Face trustworthiness e valuation is an important interpersonal quality inference , which directly determines an individual to approach or take evasive responses in human interaction. It is the gating mechanism of social interaction, which has important survival adaptation and significance of individual protection. Studies have shown that trustworthiness judgments from facial appearance approximate general valence evaluation of faces and are made after 100 ms exposure to novel faces. In recent years, researchers have discovered that the amygdale, the orbit frontal cortex, the right insula and other brain regions are activated when subjects are asked to rate the trustworthiness of faces by adopting functional magnetic resonance imaging. Several limitations exist in the previous studies’ content and material, which leaves room for future research.
