Characteristics Of Pre-school Autism Children’s Hand Movement Imitation Under Different Model Conditions

Imitation is a way of getting information in observational learning and effectively enabling the observer to acquire motor skills.Imitation is also the essential basic skills of children before developing language.Recent studies on the movement have shown that autism children have a more prominent physical imitation of defects,and affect their ability of daily living and social communication.With the application of modern science and technology in imitation training of autism,the study on the influence of model conditions on motor imitation has gradually become an important subject in the clinical work of education and rehabilitation.Based on the overview of domestic and foreign research,this paper uses self-made meaningless hand movement materials to do the test,the material is designed from four dimensions,one is the action steps,divided into one step and two steps;second is the type of action,divided into object action and non-object action;third is the demonstration of the form of action,divided into video and picture;four is the model perspective,divided into the first person perspective and the third person perspective.Because of the differences in cognitive and imitation abilities of children with different degrees of autism,different characteristics may be presented in the motor imitation.In this paper,autism children are divided into two groups:severe autism and mild to moderate autism,and explores the imitation characteristics of two group children in different model forms and model perspectives.Based on the findings of the study for the preschool children with autism to prepare for the training of targeted rehabilitation recommendations,in order to promote the development of speech in children with autism.1.Characteristics of autism children’s imitation in different model perspectives.Through the behavioral observation experiment,the children of severe autism children,mild to moderate autism children and children with typical development were tested for one-step object action and one-step non-object action.Analyze the impact of two different model perspectives(first person perspective,third person perspective)on one-step action imitation.The results of the study found that autism children in one-step and two-steps action task were significantly associated with normal children(p<0.01).The mild to moderate autism showed a first person perspective of view better than the third perspective(p<0.01;0.01<p<0.05).The first perspective of view was better than that of the third perspective(0.01<p<0.05)in the two-step imitation,and the effect of the perspective view of normal children and severe autistic children was not significant in one-step action(p>0.05).The results suggest that autistic children with mental reading and social information attention deficiencies,select the first perspective is more conducive to the autistic children to imitate.2.Characteristics of autism children’s imitation in different model forms.According to the model perspective on the impact of action imitation results concluded that the first perspective is the most conducive to promoting the movement of autistic children to imitate.Through the behavioral experiment,the author analyzes the results of the severe autism,mild to moderate autism and normal children in the first person perspective picture and video.The experimental results show that,regardless of the type of model the ability of autism children to imitate the ability to fall behind normal children(p<0.001);in one-step task,the normal children’s test results by the model form of the impact is not significant(p>0.05),but imaging modality of the children with severe and mild to moderate autism is affected by the demonstration form,which video is better than the picture form(0.01<p<0.05;p<0.001).In the two-step task,the imitate performance of severe autism and children with typical development was not significantly affected by the model forms(p>0.05),regardless of whether the order of action was imitated.However the mild to moderate autism show better results in video task(p=0.001),suggesting that there is a lack of internalization of autistic children,the form of video can better promote the autistic children on the action content and sequence of actions memory and imitation.Based on the above findings,this paper discussed the characteristics of preschool children with different degrees of autism,which are modeled under different model conditions.According to this,the author puts forward some suggestions on the training sequence and the selection of demonstration conditions in the clinical rehabilitation application.How to make better use of the results of this study to carry out intervention training for autistic children’s speech language rehabilitation to lay a good preparation skill,which is still need to continue to explore in the future.
