| Executive function is a comprehensive instruction system and a set of cognitive processes,which help us to accomplish tasks purposefully.Many studies have shown that autistic children have executive dysfunction.Behavioural stereotypes and narrow interests and attention-transfer disorders in autistic children are often associated with low executive function.However,there is noconsistent conclusion on the characteristics of executive function in autistic children,and there is no feasible and effective intervention model for their training.In this study,the executive function characteristics and intervention projects of autistic children were defined by standardized evaluation tools,and the executive function intervention model of autistic children based on robot graphical programming technology was proposed,which was verified by intervention experiments.The findings are as follows:1.The study of executive function characteristics and core project analysis in autistic children:a standardized BRIEF2 assessment tool was used to evaluate executive function in 65 autistic children.compared with 53 ordinary children of matched age,autistic children had executive dysfunction.showed significant backwardness in the fields of transformation,self-monitoring,initiation,planning/organization and working memory,so these five projects were identified as core intervention projects for executive function.2.Research on graphical programming of autistic children based on robot platform: based on the analysis of robot graphical programming at the present stage,six kinds of robot graphic programming structure tasks including sequential structure,parallel structure,conditional structure,cyclic structure,operation structure and function structure are designed.Intervention experiments were carried out on 5 autistic children.The experimental results show that autistic children can program graphically,and the six types of graphical programming structure tasks based on robot platform can be used as graphical programming tasks for autistic children.Based on the experimental results,the six types of structures are divided into three difficulty levels.3.Put forward the intervention mode of executive function in autistic children: the core of the intervention mode is to put forward problems and solve problems.Teachers create life unit theme problems,children follow the fivestep routine,using graphical programming to solve autistic children transformation,self-monitoring,startup,planning /organization and working memory ability enhancement.Based on this core,it is designde into three parts : one is the core goal of five-step routine design to solve the problem,the other is the graphic programming structure design content,the third is the life unit design series theme,at the same time,the goal and principle of intervention are defined,the intervention structure,training environment and evaluation scheme are designed,and a complete and feasible intervention model is constructed。4.A practical study on the mode of executive function intervention in autistic children: this study used a single group of experimental design before and after the intervention of 8 autistic children.The results showed that 8 autistic children had significant improvement in the performance of the core program of executive function intervention,indicating that the model had a good interve ntion effect on the executive function of autistic children.The significance of this study is:1.Overcome the lack of functionality in previous executive function evaluation through standardized BRIEF2 executive function evaluation tools.To clarify the executive function characteristics of autistic children and provide a basis items for intervention.2.Make full use of the Wu Kong robot with cartoon modeling and life sense,and six kinds of graphical programming structures with intuitive operation.The intervention strategies for five core intervention projects of executive function in autistic children were put forward to fully mobilize the participation interest of autistic children.3.Demonstrated the effectiveness of the executive function intervention model in autistic children through a complete cycle of individualized experimental studies. |
