Abstract:

The ability of recognizing ambiguous expressions is proposed to be a generally used social skill, which plays a crucial role in human social interaction. Emotion context information as a main factor which affects ambiguous expression recognition, including text description, emotional expression, color background, olfactory signal and personality factors, were reviewed in this paper. We aim to reveal the mechanisms underlying the process of ambiguous expression which was influenced by emotion context information. In the future research, the following topics should be considered: highlighting the dominant research status of ambiguous expression, defining emotional context information clearly, exploring new research paradigms and identifying brain regions that affect the transfer of valance, in order to broaden the research field of ambiguous expression recognition.

Key words: emotional context information, ambiguous expression, transfer of valance
