Objective To explore the mediating role of intelligence in the relationship between in-formation processing speed and numerical magnitude processing of hearing-impaired children. Methods A survey was conducted among 249 hearing-impaired children by using tests of Choice Reaction Time,Numero-sity Comparison,and Raven's Progressive Matrices( simplified version). Results (1) The accurate rate of information processing speed(0. 89±0. 18)of hearing-impaired children was positively correlated with that of numerical magnitude processing(0. 65±0. 15)and intelligence(11. 83±10. 34)(r=0. 165,0. 263,both P<0. 01). The reaction time of information processing speed was negatively correlated with those of numerical mag-nitude processing and intelligence(r=-0. 164,-0. 197,both P<0. 05). And there was significant positive correlation between intelligence and numerical magnitude processing (accurate rate and reaction time ) (r=0. 269,0. 140,both P<0. 05). ( 2) The accurate rate of information processing speed significantly predicted that of numerical magnitude processing in hearing-impaired children( β=0. 17,t=2. 64,both P<0. 01). The reaction time of information processing speed significantly predicted that of numerical magnitude processing in hearing-impaired children(β=-0. 16,t=-2. 61,both P<0. 05). And intelligence played a complete medi-ating role in this relationship and the moderating effect were 36. 71% and 31. 25%. Conclusion Information processing speed has indirect effects on numerical magnitude processing through intelligence in hearing-im-paired children.

Objective: To examine attentional bias in relation to body image problems among adolescents. Methods: A total of 61 adolescent students from a junior high school in Qionghai City were selected as the research objects and divided into body image problems group( n =30) and non body image problems group( n =31). A 2×2 mixed design was employed to examine adolescents with body image problems and adolescents with no body image problems, as well as body images depicting high and low attractiveness. Point detection experiments were conducted to measure the participants responses to the detection point. Two types of behavioral data were used including the reaction time bias index and the attentional disengagement index. Results: A significant difference was observed in the group main effect of the reaction time bias score ( F =175.64, P <0.05). The response bias scores of adolescents with body image problems [The picture was high medium(39.39±15.13)ms;The picture is low medium(28.40±26.07)ms] were greater than those of adolescents with no body image concerns [(-18.31±16.57)(-17.83±9.19)ms], which indicated that the subject had a body image picture attention maintenance; the main effect of the attentional detachment index group was significantly different ( F =38.21, P <0.05). The attentional detachment indexwas higher among adolescents with a disordered attentional body image [Attention disengagement index of high volume image(18.42±13.95)ms;Attention disengagement index of low body image(15.84±19.62)ms] than among those who had no body image concerns [(-4.05±13.49)(-1.83±9.72)ms], indicating that the subject has a body image. When attending to the images, these participants had difficulties in disengaging their attention. Conclusion Adolescents with body image problems show an attentional bias towards body image pictures, and the results indicated an attentional alert maintenance mode.

Abstract There are four typical potential protective and risk factors in the context of campus bullying:social support, role choice of bystander, moral disengagement, and ethnic/racial differences. Adolescent victims of bullying can improve their mental health by obtaining different social support to maintain their sense of self worth. The role selection of bystander should consider both the psychological factors of social information processing theory and the situational evaluation factors of transactional model of appraisal and coping. Moral disengagement is the cognitive distortion mechanism that leads to individual bullying behavior. Ethnic/Racial differences seem to have less impact on bullying in Chinese schools. Future research should consider the influence of frequency and intensity of bullying and being bullied, attach importance to the collection and analysis of multi party data, interpret the results of cross sectional and longitudinal studies in conjunction, explore the construction of an integrated model of the impact of multiple factors on bullying, and further verify and explore the possible causal relationship in the situation of campus bullying.

Objective: To explore the mediating role of intelligence in the relationship between information processing speed and numerical magnitude processing of hearing-impaired children. Methods: A survey was conducted among 249 hearing-impaired children by using tests of Choice Reaction Time, Numerosity Comparison, and Raven's Progressive Matrices(simplified version). Results: (1)The accurate rate of information processing speed(0.89±0.18)of hearing-impaired children was positively correlated with that of numerical magnitude processing(0.65±0.15)and intelligence(11.83±10.34)(r=0.165, 0.263, both P<0.01). The reaction time of information processing speed was negatively correlated with those of numerical magnitude processing and intelligence(r=-0.164, -0.197, both P<0.05). And there was significant positive correlation between intelligence and numerical magnitude processing (accurate rate and reaction time ) (r=0.269, 0.140, both P<0.05). (2)The accurate rate of information processing speed significantly predicted that of numerical magnitude processing in hearing-impaired children(β=0.17, t=2.64, both P<0.01). The reaction time of information processing speed significantly predicted that of numerical magnitude processing in hearing-impaired children(β=-0.16, t=-2.61, both P<0.05). And intelligence played a complete mediating role in this relationship and the moderating effect were 36.71% and 31.25%. Conclusion Information processing speed has indirect effects on numerical magnitude processing through intelligence in hearing-impaired children.

Exploring neural markers that predict trust behavior may help us to identify the cognitive process underlying trust decisions and to develop a new approach to promote interpersonal trust. It remains unknown how trust behavior may be predicted early in the decision process. We used electrophysiology to sample the brain activity while participants played the role of trustor in an iterative trust game. The results showed that during the trust generation stage, the trust condition led to higher frontocentral beta band activity related to cognitive inhibition compared to the distrust condition (item level). Moreover, individuals with higher frontocentral beta band activity were more likely to perform trust choices at the single-trial level (individual level). Furthermore, after receiving reciprocity feedback on trial
