Objective To compare eye expression recognition in stable outpatients with schizophrenia with that in normal controls and to explore the relationships between eye expression recognition and social functioning.Methods 107 schizophrenic outpatients and 66 normal controls matched in age,sex and years of education were assessed with Eye Basic Emotion Discrimination Task(EBEDT) and Eye Complex Emotion Discrimination Task(ECEDT).The patients were also assessed with Social Disability Screening Schedule (SDSS).Results The correct numbers were significantly lower for patients to identify basic emotions of eye expressions(13.2±3.8 vs16.0±2.6,P<0.01) and complex emotions of eye expressions(17.9±4.3 vs 20.6±3.5,P<0.01)than those for controls respectively;the correct numbers to identify anger(3.1±1.0 vs.2.1±1.2,P<0.01),fear(1.8±1.0 vs 1.3±1.0,P<0.01) and disgust(1.8±1.1 vs 1.4±1.2,P<0.05)for controls were higher than those for patients significantly.The correct numbers to identify total basic emotions(r=-0.335,P<0.05)and total complex emotions (r=-0.374,P<0.05)in eye expressions showed negatively correlated with the total scores of SDSS in the patients after controlling age and total score of PANSS.Conclusions The ability to recognize basic and complicated emotions in eye expressions in the outpatients with schizophrenia is lower than that in the controls. It shows positively correlated with social functioning moderately in the patients.

Objective:To investigate the attention deployment emotion regulation disorder and its neural mechanisms in major depressive disorder(MDD).Methods:Twenty-six MDD patients(MDD group) and twenty-nine healthy control individuals(control group) were enrolled in this study.The accuracy and reaction time were recorded in the attention deployment behavioral paradigm.Neuroscan 64 Brain Evoked Potentiometer was used to detect the N1 and P3 components of the above two groups of subjects.SPSS 16.0 software were used to analyze the data.Results:(1)In the accuracy of attention deployment paradigm, the group main effect was significant ( F=11.626, P=0.001), indicating that the MDD group (0.82±0.01) was significantly lower than the control group(0.89±0.01)( P=0.001). In the reaction time of attention deployment paradigm, the group main effect was significant( F=16.55, P<0.01), indicating that the MDD group (1 460.82±41.86)ms)was significantly higher than the control group(1 226.31±39.63)ms)( P<0.01). (2)In the event-related potential of attention deployment paradigm, the group main effect of N1 was not significant ( F=2.949, P=0.092), and the interaction between task and group was significant ( F=4.756, P=0.034), indicating that the N1 amplitude induced by the MDD group in the calculation task(-3.699±0.441)μV) was significantly smaller than that of the control group (-5.055±0.418)μV)( P=0.030). The group main effect of P3 was not significant ( F=1.165, P=0.285), and the interaction between task and image attributes was significant ( F=11.602, P=0.001), indicating that the P3 amplitude induced by negative images(2.757±0.438)μV) was significantly higher than that of neutral images (1.963±0.460)μV)( P=0.002). Conclusion:Patients with MDD have difficulty transferring attention in emotional strategies, and it occurs in the early stages.
