| Sentence with "Arrive" is a dynamic azimuth sentence that children learn first and use most frequently in their early life.It can emphasize the end point of displacement,with displacement purpose and displacement mode attached.At present,there is a lack of research on the characteristics and intervention of dynamic orientation sentence acquisition in children with normal development and autism.Therefore,this study takes the most typical dynamic orientation sentence as the breakthrough point,comprehensively considers the mastery of autistic children from the two ability dimensions of comprehension and expression,summarizes the common errors of autistic children when they express different types of sentence with "arrive" and analyzes the causes.In addition,this study also designed a stepped sentence intervention course in line with the understanding and expression characteristics of autistic children,and verified its effectiveness through individualized intervention.1.A study on the development of comprehensible and expressive ability of sentence with “arrive” in the ordinary developing childrenIn this study,the comprehension and expression ability of sentence with "arrive" of 30 ordinary developing children aged 3-4 years were investigated.The results showed that :(1)the comprehension ability of sentence with "arrive" of ordinary developing children was mature and stable at the age of 3 years;(2)The expression ability of sentence with "arrive" in the average developing children develops continuously during 3-4 years old,and the difficulty of sentences with conjunction predicate structure is significantly higher than that of sentence with basic structure(p< 0.001),but the difference of difficulty between them decreases with age.2.A study on the characteristics of autistic children’s comprehension and expression ability of sentence with "arrive"In this study,17 autistic children and 17 ordinary developing children with matching PPVT-R scores were compared in terms of understanding and expression of sentence with "arrive".The results showed that :(1)the understanding and expression of sentence with "arrive" in autistic children were significantly lower than those in ordinary developing children with matching PPVT-R scores(p < 0.05);(2)Autistic children acquire different types of "arrive" sentences in the same way as the normal children.They first acquire the basic structure of sentence,and then acquire the sentences with a conjunction predicate structure.(3)Autistic children have a variety of error types when expressing the sentence with "arrive".In the sentence of the basic structure,the phenomenon of "autonomous sentence pattern" is the most prominent,and in the sentence with the connected structure,the phenomenon of "missing components" is the most prominent.3.A study on the intervention of comprehension and expression ability of sentence with "arrive" in autistic childrenBased on the results of the feature study,this study designed a stepped intervention course for the comprehension and expression ability of the sentence with "arrive",and adopted the form of individualized intervention to intervene 4 autistic children.The results showed that :(1)After the intervention,the correct understanding rate of sentence and expression rate of autistic children increased by 25% ~ 43.75%and 45.74% ~ 81.25%;(2)After intervention,the types of errors in the expression of the sentence with "arrive" in autistic children are significantly reduced,the grammatical structure is more complete and the semantic expression is more accurate. |
