RESUMEN
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

RESUMEN
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.
