Abstract:
Objective:To investigate the characteristics of executive function of preschool children with high functioning autism spectrum disorder (HFA) and with global developmental delay (GDD), and the differences among HFA, GDD and typically developmental (TD) children.Methods:From January 2020 to January 2021, 20 male HFA, 20 male GDD and 20 male TD children aged 4-6 years who visited the Psychological Behavior Clinic of the Child Health Department of Guiyang Maternal and Child Health Hospital and the Developmental Behavior Clinic of the Children Health Department of the Ninth People's Hospital in Chongqing were selected for comparative study.The executive function of HFA, GDD and TD children was assessed with the behavior rating scale of executive function-preschool version(BRIEF-P) and the executive function task program (EF-TOUCH). SPSS 26.0 software was used for statistical analysis, including variance test, independent sample t-test, χ2 test, Kruskal Wallis test and Mann-Whitney U test. Results:In the EF-TOUCH program task, the accuracy of the three groups of children's performance in the pig task (Pig), the silly sounds game (SSG), the working memory task (pick the picture, PTP) and the task of cognitive flexibility (something's the same, STS) were statistically different(Pig: HFA group: 0.87(0.76, 0.99), GDD group: 0.97(0.85, 0.99), TD group: 1.00(0.98, 1.00), χ2=15.646, P<0.001; SSG: HFA group: 0.76(0.53, 0.91), GDD group: 0.76(0.65, 0.99), TD group: 0.94(0.76, 1.00), χ2=6.448, P=0.040; PTP: HFA group: 0.66±0.18, GDD group: 0.66±0.19, TD group: 0.78±0.11; F=3.221, P=0.048; STS: HFA group: 0.67(0.63, 0.70), GDD group: 0.72(0.46, 0.78), TD group: 0.87(0.83, 0.90), χ2=26.898, P<0.001). The accuracies of Pig, SSG, PTP and STS in HFA group were significantly lower than those in TD group(all P<0.05), and the accuracies of Pig and STS in GDD group were significantly lower than those in TD group(both P<0.05). In inhibition control, there were statistically differences in response time of Pig and SSG among the three groups (Pig: HFA group: (1 694.36±222.83)ms, GDD group: (1 513.46±244.91)ms, TD group: (1 444.84±197.95)ms, F=5.810, P=0.005; SSG: HFA group: (2 202.42±195.58)ms, GDD group: (2 116.52±323.27)ms, TD group: (1 937.17±252.74)ms, Z=4.610, P=0.014). There were no significant differences in the reaction time of Arrows task ( P>0.05). There were significant differences in BRIEF-P inhibition control, organizational planning, inhibition self-regulation, cognitive flexibility and total scores among the three groups ( P<0.05), while there were no significant differences in the scores of other factors and dimensions ( P>0.05). Conclusion:The executive function of pre-school children with high functioning autism spectrum disorder and children with global developmental delay is impaired.The executive function of children with high functioning autism spectrum disorder and children with global developmental delay is significantly different from that of typically developmental children of the same age.Moreover, the executive function of children with HFA is more severely damaged from all components than that of children with GDD.
