Abstract:

Trust behavior is mainly influenced by biological and environmental factors. Through quantitative or molecular genetic studies, researchers found that genes associated with trust include oxytocin receptor genes, serotonin transporter genes, and AVPR1A gene. From a biological perspective, genes affect the production and release of hormones, while the activities of hormones and specific brain regions affect trust. From gene-environment interaction theory, genes may play a moderating role between the environment and trust behaviors. An important direction for future research is to investigate the mechanism of the occurrence and development of trust from a more integrated and systematic perspective, and to further confirm the genetic role in the genetic mechanism of trust.

Key words: trust, oxytocin receptor gene, serotonin transporter gene, AVPR1A gene
