Characteristic analysis of inhibitory control and cognitive flexibility in hearing-impaired children
Objective To analyze the characteristics of inhibitory control and cognitive flexibility in hearing-impaired children.Methods From March to April 2023,a convenience sampling method was used to select 33 hearing-impaired children from a special education school in Meizhou City,Guangdong Province,and 35 normal-hearing children from two ordinary schools as participants.Inhibitory control and cognitive flexibility of the participants were assessed by the Flanker task and the dimensional change card sorting(DCCS)task.Statistical analysis was conducted using SPSS 26.0 software,and independent sample t-test was used to compare the differences in reaction time and accuracy rate between two groups of participants.Results There were no significant differences in the Flanker task reaction time((558.39±123.65)ms vs(566.11±118.20)ms)and accuracy rate((0.93±0.10)vs(0.96±0.04))between hearing-impaired chil-dren and normal-hearing children(t=-0.295,-1.645,both P＞0.05).The hearing-impaired children had significantly longer reaction time((1 019.60±131.08)ms)than the normal-hearing children((857.85±129.19)ms)(t=4.046,P=0.001)in the DCCS task,while there was no statistically significant difference in the accuracy rate between hearing-impaired children(0.62±0.16)and normal-hearing children(0.57±0.15)(t=-1.602,P＞0.05).Conclusion There is no difference in inhibitory control ability between hearing-impaired children and normal-hearing children,but the hearing-impaired children have a lag in cog-nitive flexibility.
