Abstract:
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.
