조음점 지시법과 짝자극 훈련 프로그램이 인공 와우 아동의 치경음 개선에 미치는 효과

Abstract

The purpose of this study is to examine th effect on alveolar sound /ㄷ/ production by applying the phonetic placement procedure and paired-stimulus treatment program in the children with cochlear implant. The subjects of this study were three lower-grade students with cochlear implant attending I school in Gwangju. Their K-WISC-Ⅲintelligence test showed their normal range and they had no emotional or sensory disability, but they had in common in phonetic error in alveolar sound /ㄷ/. This study used the multiple baseline design across subjects in single subject study, and the experimental procedure consisted of three steps: baseline, mediation, and maintenance. Also, pretest and posttest were conducted in order to find out the effect of phonetic intelligibility by syllable. The results are as follows. First, the use of the phonetic placement procedure and paired-stimulation treatment program suggests the increase in correct alveolar sound production with all subject children. Finally, the use of the phonetic placement procedure and paired-stimulation treatment program suggests the increase in correct phonetic production of alveolar sound in the level of word and phrase by syllable with all subject children. Based on the results and discussion of this study, the phonetic placement procedure and paired-stimulation treatment program may improve the error of alveolar sound, /ㄷ/, and may be very effective in maintaining phonetic patterns after closing a treatment.
