초록

본 연구는 말처리 과정에서 나타날 수 있는 조음장애의 원인 또는 관련 요소를 파악하기 위하여 연령과 성별을 통제한 조음장애아동 35명과 정상아동 35명을 대상으로 말운동 프로그래밍 능력을 비교하고 그 특성을 파악 하였다. 이를 위하여 피험자에게 2음절과 3음절의 단어와 비단어를 제시하고 빠르게 반복하는 과제를 수행하게 하였다. 그 결과, 정상아동에 비하여 조음장애아동이 더 큰 단어와 비단어의 반복 소요시간 변화를 보였으며, 더 많은 조음오류수 변화를 보였다. 그러나 조음장애아동은 자음정확도와 소요시간 변화 및 조음오류수 변화에서 유의미한 상관을 보이지 않았다. 이러한 연구결과는 조음장애아동이 정상아동에 비하여 말운동 프로그래밍 능력에서 취약성을 보였지만, 자음정확도의 정도에 따라서 그 취약성이 어떤 경향을 보이는 것이 아님을 시사한다.

This study attempted to reveal the physiologic etiology or related factors associated with speech processing by comparing the ability of speech motor programming of children group with functional articulation disorders with that of children group without articulation disorders. For the purpose, subjects were 35 children with articulation disorder and 35 children without articulation disorder whose age ranged from 5 to 6 years. They were asked to repeat each words and nonwords rapidly. Task words were consisted of 2 syllable or 3 syllables and were familiar to 5 to 6 year old children. Nonwords were formed from previously selected words by vowel modification maintaining the phonetically balance. Required time in each repetition with words and nonwords was measured by using spectrograph and number of articulation error also were measured. To compare the group performance, independent t - test was used.
The results showed that children with articulation disorder revealed significantly greater differences in required time of repeating words and nonwords in both 2 syllables and 3 syllables. And children with articulation disorder showed larger difference in the number of articulation error of repeating words and nonwords as compared to the children without articulation disorder. But, the correlation between the percentage of consonants correct and the two parameters in the articulation disorder group was irrelevant. These results point out to the fact that children with articulation disorder have a poor ability of speech motor programming compared to the children without articulation disorder. On the other hand, the poor ability does not have any relation with the severity of articulation disorder. These results suggest either general or individual characteristics of children with articulation disorder.
