Abstract：Face trustworthiness evaluation 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.
