Abstract:
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.
