CPRA在自闭症儿童声母发音干预中应用的个案研究

A Case Study on the Application of CPRA to Intervening Initial Consonant Articulation of Autistic Child

采用跨行为多基线实验设计,以周期语音修复法程序为干预过程,通过"练习-产出"模式的游戏为媒介,对一名自闭症儿童的3种发音方式(塞音、擦音、塞擦音)的9个声母发音进行干预,结果显示:被试的3种发音方式具有显著提高,目标声母的模仿正确率显著增加;干预效果具有良好的维持作用,且具有良好的社会效度。

A multiple-baseline design across behaviors was employed to test the efficacy of cycles phonological remediation approach(CPRA)on improving the initial consonant articulation ability of one autistic child.In this study,the"production-practice"game was adopted as a medium by CPRA to intervene 9 consonants of 3 articulation modes(stop,fricative and fricative)of the participant.The results showed that:the targeted articulation modes were significantly improved,and the imitation accuracy of target consonant was significantly increased;the intervention effect was found to be maintained well after the intervention and showed a high social validity.
