Objective:To explore the emotional effect on social perception of faces by comparing happy expression and neutral expression in young adults.Methods:Thirty-two college students were recruited through advertisements to watch a series of pictures of young adults ’ happy and neutral faces and rate their 13 personality traits(trustworthiness,emotional stability,responsibility,sociability,attractiveness,likeability,confidence,intelligence,aggressiveness,dominance,competence,warmth,tenacity) on 7 points scales.The score of each personality trait evaluation and the response time(ms) for evaluation were taken as the dependent variables to conduct the repeated measurement ANOVA with expression type,picture gender and personality trait type as within independent variables,and bonferroni correction was used for multiple comparisons.Results:The results showed that the young adults ’ happy expression got higher scores than their neutral expression(Ps <0.0038) on trustworthiness,sociability,attractiveness,likeability,confidence,warmth.As for dominance and aggressiveness,the young adults ’happy expression got lower scores than their neutral expression(Ps <0.0038).In terms of reaction time,it took less time to evaluate the personality for the young adults’ happy faces than the young adults’ neutral faces [(1675.2±493.5) ms vs.(1742.3±547.7) ms,P <0.05].Conclusion:Compared with the young adults’ neutral expression,their happy expression may lead to the perceptual outcome of the positive personality traits,and reduce the perceptual outcome of dominance and negative personality traits,and promote the processing speed of social perception of faces.

Objective: To explore the characteristics of the social cognition in patients with high/low functioning early onset schizophrenia (HF-EOS). Methods: Eighty-four 13-18 years old patients with early onset schizophrenia and 45 gender-, age-, and level of education-matched healthy controls (HC) were selected. The diagnosis was made according to the criteria of the International Statistical Classification of Diseases and Related Health Problem, Tenth Revision (ICD-10) for schizophrenia. All patients were divided into HF-EOS group (total score >7, n=41) and LF-EOS group (total score <4, n=43) in the three aspects total score of social attachment, social competence and functional capacity. All patients were assessed with the Eye Basic Emotion Discrimination Task, Reading the Mind in the eyes, Yoni task and Faux Pas Recognition task. Results: Compared with healthy controls, LF-EOS patients performed poorer on Reading the Mind in the eyes task [(７１±１８) vs. (８３±１３), Ｐ＜０.０1] and Recognizing Faux pas [(８±２) vs. (９±２), Ｐ＜０.０５]. HF-EOS and LF-EOS patients performed worse than the controls on second-order affective condition of the Yoni task [(８０±１４), (７５±１５) vs. (８６.５±１０.０), Ｐ＜０.０１] and understanding paux pas (１７±５), (１４±５) vs. (２１±６), Ｐ＜０.０１]. Conclusion: It suggests that HF-EOS have preserved social perceptual abilities compared to LF-EOS patients. HF-EOS patients and LF-EOS patients both have impaired theory of mind compared to controls.
