Abstract:
Objective To comprehensively investigate the subcomponent characteristics of inhibitory control for children with autism spectrum disorder(ASD)aged 4-5 years under experimental and natural environments.Methods Thirty children with ASD aged 4-5 years and 30 chronological-age and intellectual level-matched typically developing children were recruited.The Simon task,Go/nogo task,and Stroop task were used to examine the conflict response inhibition,prepotent response inhibition,and interference control subcomponents of inhibitory control,respectively.The inhibit subscale of the behavior rating inventory of executive function-preschool version was employed to assess children's inhibition in daily natural situations.Results Under the incongruent condition of the Simon task,there were no significant differences in mean reaction time and accuracy between ASD group and the control group(P>0.05).In the Go/nogo task,the ASD group demonstrated elevated false positive errors compared to the controls[3.10%(0,6.20%)vs.0(0,0.78%),P=0.005].However,there were no significant differences in mean reaction time and false alarm error between ASD group and the control group(P>0.05).In the Stroop task,there were no significant differences in the accuracy and mean reaction time between ASD group and the control group(P>0.05).Additionally,the ASD group scored significantly worse than the controls in the inhibit subscale of BRIEF-P[(60.47±9.63)vs.(54.23±7.45),P=0.007].Conclusions The inhibitory control of children with ASD aged 4-5 years are partially impaired in a structural experimental setting while severely deficient in a natural environment.
