Abstract:

Facial trustworthiness plays a key role in how we express and understand social signals. During social interactions, people quickly judge the trustworthiness of others through subtle facial cues in order to make choices in daily life. The researchers delved into behavioral and ERP studies related to the time course of facial trustworthiness processing, and explored the life-span development of facial trustworthiness, as well as the influence of face emotions and face gender on the evaluation of facial trustworthiness. Further research is needed to improve the ecological validity of stimuli used in facial trustworthiness studies, to expand the study of facial trustworthiness in adolescents and aging population, and to consider the contextual effects on facial trustworthiness assessment.

Key words: facial trustworthiness, life-span development, emotion, gender, ERP
