ABSTRACT
Objective:To explore the difference of perceptual processing in ERP between cartoon faces and real faces.Methods:Thirty college students were selected and adopted the face recognition paradigm.The independent variables were face type (real, cartoon) and emotional type (positive, neutral, negative). The dependent variables were response time and the amplitude and latency of ERP data.SPSS 22.0 software was used for repeated measurement analysis of variance.Results:The reaction time of cartoon expression ((455.58±55.18)ms) was shorter than that of real face ((471.49±63.02)ms) of college students.There was no significant difference in N170 amplitude and latency among different faces and expressions(all P>0.05). The vertex positive potential VPP latency of positive real faces ((159.89±13.93)ms) was shorter than that of positive cartoon faces ((165.68±14.35)ms) ( PVPP<0.05). It was easily affected by perceptual load, but negative emotion was not affected by it.In the late processing stage of late positive potential(LPP), the amplitude of positive emotional real face ((10.4±1.22)μV) was higher than that of cartoon ((4.26±0.53)μV), and that of negative emotional cartoon face ((3.84±0.36)μV) was higher than that of real face ((1.9±0.24)μV) ( PLPP<0.05). Conclusion:There are no differences in early stage N170, and the late processing stage, the real faces have an overall advantageous effect on positive emotion, and the local characteristics of negative emotional cartridge wells are more superior.
ABSTRACT
Objective:The study seeks to explore the factors influencing the psychological status and sleep quality of medical workers amid the ongoing COVID-19 pandemic, in order to provide data sources and theoretical basis for the development of relevant psychological intervention programs.Methods:Employing the convenience sampling method, general information questionnaire (age, gender, marital status, educational background, job status, etc.), Generalized Anxiety Disorder-7 and Patient Health Questionnaire, epidemic stress index scale, and sleep quality questionnaire were distributed to medical staff between February 18 and April 3, 2020, using the PEM mental health care platform of by ZhongShengKaiXin for medical staff issued. Descriptive, single factor, and correlation analyses, as well as multiple linear regression analysis were used to analyze the data.Results:Overall, 24, 845 questionnaires were collected from 23 provinces, of which 24, 687 were valid, with a recovery rate of 99.36%. The findings showed that the proportion of medical personnel with symptoms of anxiety and depression was 50.58% and 51.37%, respectively; 16.11% had poor or very poor anti-stress ability; and 71.78% reported poor or very poor sleep quality. There was a positive correlation between anxiety, depression, anti-stress ability, and sleep quality ( P<0.05). Anxiety was positively correlated with depression, stress tolerance, and sleep quality( r=0.787, 0.667, and 0.486, all P<0.001); depression was positively correlated with stress tolerance and sleep quality ( r=0.709 and 0.586, both P<0.001); and stress tolerance was positively correlated with sleep quality ( r=0.452, P<0.001). Multiple linear regression analysis results showed that age, gender, marital status, educational background, professional title, job status, and participation influenced the anxiety levels of medical personnel in the backdrop of the pandemic ( P<0.001). Depression levels of medical staff were influenced by gender, educational background, job position, and participation ( P<0.001), while gender, marital status, educational background, job position, and participation influenced the stress tolerance levels ( P<0.001). The sleep quality of medical workers was influenced by age, gender, job position, participation in the fight against the pandemic, and professional title ( P<0.001). Conclusions:Amid the ongoing COVID-19 pandemic, medical staff reported poor mental health status and sleep quality, which can be attributed to diverse factors. The research findings can be useful for assisting medical staff to strengthen their self-cognition, while also providing certain psychological counseling data and theoretical basis for management departments.
ABSTRACT
In order to optimize the teaching process, improve the teaching quality, and cultivate military psychologists with high practical skills, this study explored the training model of military psychologists based on flipped classroom. First of all, the content of "psychological publicity education, psychological assessment, psychological counseling, mental illness diagnosis, psychological training and psychological service" was introduced for training military psychologists. Secondly, theoretical basis based on flipped classroom was analyzed, and coherence between students' realistic needs and student-centered learning theories was elaborated. Finally, requirements for implementing flipped classroom in the training of military psychologists were analyzed. Teachers should thoroughly understand students' actual needs, formulate targeted curriculum standards and teaching objectives, and utilize team strength to provide better service for teaching. Students should improve their study initiatives and learn actively. Teaching media should not only be the carrier of teaching content, but also meet requirements of students' self-study and teacher-guided teaching.

ABSTRACT
Objective To explore the time course of response inhibition function in juvenile delin-quents with antisocial personality characteristics.Methods The healthy control group ( n=21),juvenile delinquents with antisocial personality characteristics ( CD +AP ) ( n=18) and juvenile delinquents ( CD) ( n=18) were selected in current study by recording the event-related potentials in a Go/Nogo task.N2 and P3 components of event-related potentials were analyzed.Results Behavioral results showed that Nogo cor-rection rate of control group ((93.13±2.71)%) were significantly higher than CD group ((87.51±2.82)%, P<0.01) and CD +AP group((85.63±2.45)%, P<0.01).In CD+AP group,the amplitude of the N2nogo ( (-1.82±1.64)μV) was significantly lower than control group ( (-6.36±2.93)μV, P<0.01) ,and the am-plitude of the P3nogo ((5.52±2.79)μV) was significantly decreased than healthy control ((11.26±4.92)μV, P<0.01).In CD group,the amplitude of P3nogo ((5.20±3.17)μV) was significantly reduced than healthy control ((11.26±4.92)μV, P<0.01).Conclusion N2nogo and N2d are associated with the early phases of response inhibition and reflected response conflict.P3nogo and P3d are associated with the late phases of response inhibition and monitored inhibitory control.These data suggest that CD+AP participants exhibited im-paired response conflict and inhibitory control.This may be associated with persistent antisocial behavior.
ABSTRACT
Objective To explore the effect of weightlessness simulation on processing speed of mental rotation of males in 72 h head-down tilt,in order to further reveal human performance changes caused by weightlessness.Methods During 72 h weightlessness simulation (9 am day 1 to 9 pm day 4,head-down tilt started from 9 pm day 1),16 male subjects were processed speed of rotation data byhand picture mental rotation (test 8 times),using self cross-references design,and the variation of processing speed of mental rotation by duration was analyzed.Results The linear regression analysis showed,the reaction time of each time point for each subject as the independent variable,the angle of rotation as the dependent variable,with the extension of simulated weightlessness time.The intercept(constant term of the regression equation),indicating the processing speed of non-rotation,were gradually increased with HDT time,but didn(t) reached significantly difference (F(3,14) =0.551,P =0.650) ;the slope(Regression coefficient of the regression equation),indicating the processing speed of rotation.were gradually increased with HDT time,and reached the significantly difference (F(3,14) =4.338,P =0.009).The value of intercept and slope was like upside-down U in three days,and reached the highest value at day 2.Conclusion Weightlessness simulation have affection on the speed of mental rotation,especially on the rotation speed.
ABSTRACT
Objective To explore the differences between the minority nationality and Han recruits in army occupational adaptability.Methods 3 213 recruited youths coming from 29 autonomous counties of minority nationalities,Yunnan Province were tested by 2011 Chinese enrollment psychological test system to explore the differences of the intelligence adaptability and character trait adaptability between the minority nationality and Han recruits.Results There were obvious differences in the eligible rates of intelligence and character trait between minority nationality and Han recruits ( x2 =13.3,9.0; P ＜ 0.01 ).The intelligence eligible rates of Yi,Hani,Wa recruits (78.1％,76.8％,68.2％,respectively) were significantly lower than those of Han recruits (84.0％) (P＜0.01 ),and time used in three intelligence test was all significantly longer than Han recruits(P ＜ 0.05 ).Naxi and Dai recruits' time used in word reasoning ( ( 109.2 ± 20.9) s; ( 123.9 ± 32.5 ) s,respectively) was both longer than Han recruits' (P＜0.01).In the fact of character trait,the eligible rates of Hani,Wa recruits (67.8％,64.3％,respectively) were significantly lower than that of Han recruits (78.1％) (P ＜ 0.01 ).The Hani average score of T dimension (57.9 ± 17.5) was obviously higher than the Han's score (52.2 ± 16.5) (P ＜ 0.05 ).All dimensions average scores except T and D dimension of Wa recruits were all significantly higher than those in Han recruits(P ＜ 0.05 ).Conclusion Every minority nationality has its unique differences in armyoccupational adaptability from Han.Ethnic factor may be an important reference for new recruits' selection,education and management.
ABSTRACT
Objective To explore the relationship between schizotypal personality proneness and intelligence .Methods 1905 subjects were tested by Chinese Soldier Personality Questionnaire(CSPQ).According to the results of CSPQ,the subjects were divided into high-risk subjects and normal ones.The Words Reasoning Test, the Arithmetic Reasoning Test and the Assembling Test were used to evaluate the intelligence,and the scores of these tests were compared between the two groups.Correlation coefficient between schizotypal personality proneness and intelligence was calculated.Results The scores of the Words Reasoning Test,the Arithmetic Reasoning Test and the Assembling Test in high-risk subjects were significantly lower than those in normal ones((87.83±18.42)VS(101.37±13.48),P<0.01;(91.74±14.26)vs(101.65±14.62),P<0.01;(87.70±18.82)VS (101.73±14.26),P<0.01).Schizotypal personality proneness was significantly correlated with the scores of intelligence(r=-0.39,P<0.01).Conclusion Lower intelligence level is found in the group with schizotypal personality proneness.Intelligence is correlated with schizotypal personality proneness.
ABSTRACT
Objective To explore the structure of violent attitude and the predictive character of the passionate criminal and recidivist. Methods This study used FMMU-Abnormal Personality Risk Factors Inventory (FMMU-APRI) for measuring explicit violent attitude of the passionate criminal and recidivist in prison; while used the picture Attitude Activation paradigm (AAP) for assessing implicit violent attitude. Results The AAP results showed that parts of passionate criminal and recidivist had reversed priming effect, according to whether reversed, there were divided into four types: no-reversal passionate criminals, reversal passionate criminals, no-reversal recidivists and reversal recidivists, VIO scores of no-reversal passionate criminals and recidivists recidivist were significantly higher than the norm, as reversal passionate criminals and recidivists had no significance; in noreversal passionate criminals, compatible response rate was 1.104, incompatible response rate was 1.053; in reversal passionate criminals, compatible response rate was 1.042, incompatible response rate was 0.997; in no-reversal recidivists, compatible response rate was 1.059, incompatible response rate was 1.097; in reversal recidivists , compatible response rate was 1.039, incompatible response rate was 0.998, as each group had strong priming effect, and each group had a dissociation of implicit and explicit violent attitude. Conclusion The results suggest that offenders who have committed a crime in the same category also had a different violent attitude; and integrating indirect methods with direct methods would predict a crime more accurately.
