The Personality Influence Factors of Ecological Microexpressions Recognition and Natural Exposure Training Effect: Openness, Depression and Gender

With the in-depth exploration of emotion, criminal investigation and other fields, the research on microexpressions has become one of the hot topics. In the current study, it was the first time to explore the influence factors of the recognition and natural exposure training of ecological microexpressions (i.e. microexpressions under different expressions backgrounds). A total of 87 (45 males and 42 female) undergraduates and postgraduates from Soochow University were randomly selected to participate in the research. This study used the microexpressions data of EMERT, except that the openness subscale and the Beck Depression Inventory was measured for the same participants. It was found that: (1) Openness was positively correlated with some ecological micro-expression recognition, and was positively or negatively correlated with the natural exposure training effect, but was not correlated with the training effect of any micro-expression recognition under neutral backgrounds. (2) The Baker's depression degree was positively correlated with some negative microexpressions recognition, and was positively correlated with disgust under fear training, and was negatively correlated with some fear microexpressions recognition training. (3) The recognition of disgust under sadness and training effect of fear under surprise of women were significantly higher than those of men, but the recognition of surprise under sadness and training effect of disgust under neutral of women were less than those of men.
