Abstract:
Objective Inhibitory ability plays an important role in individuals' development process.It has close relationship with intelligence and other cognitive ability.This study aims to explore the development of inhibitory ability on 7- to 12-year-old children.Methods A sample of 187 children aged from 7 to 12 were divided into three age-groups:7- to 8-year-old,9- to 10-year-old and 11-to 12-year-old.They perfonned the Stroop Color and Word Test and their reaction time and accuracy were recorded.Results Compared with incongruent trials ( ( 801.88 ± 344.05 ) ms ),the reaction time on congruent trials ( ( 743.16 ± 227.20ms ) of all the children was shorter( F ( 1,181 ) =7.29,P ＜ 0.0 1 ).The accuracy of congruent trials (0.94 ± 0.11 ) was higher than that of incongruent trials (0.90 ± 0.13 ) (F ( 1,181 ) =28.41,P ＜ 0.001 ).The reaction time difference of 7- to 8 -year-old children ( 117.81 ± 396.68 ) ms was longer than that of 9- to 10-year-old children ( ( 24.70 ± 177.65 ) ms) (P ＜0.05).There was no significant difference between the reaction time of difference 9- to 10-year-old children and 11- to 12-year-old children ( (32.44 ± 120.07 ) ms) (P ＞ 0.05 ).The gender effect was not significant (F ( 1,181 )=1.69,P＞ 0.05).Condusion The inhibitory ability increases from 7 to 12-year-old.The ability of 9-to 12-year-old children is reasonably stable.There is no gender effect on children's inhibitory ability.
