Abstract

According to Demand and Capacity Model (DCM), external and internal environments influence the disfluency of children who stutter (CWS). This study investigated the effects of simultaneous changes in motoric and linguistic demands on CWS and children who do not stutter (CWNS). Participants were 4-6 years old CWS and CWNS. A sentence imitation task with changes in speech rate, utterance length, and sentence complexity was used to examine their effects on children's disfluency. When the utterance length changed, CWS showed more disfluency regardless of utterance length and as the speech rate changed, CWS showed more disfluency at fast speech rate than CWNS. When the utterance length and speech rate changed, at fast speech rate, CWS showed more disfluency in both utterances than CWNS. When sentence complexity changed, CWS showed more disfluency than CWNS in complex sentences. Changes in linguistic elements such as speech rate, utterance length, and sentence complexity affect disfluency in CWS, especially when they were exposed to faster, longer, and more complex sentences. This indicates that CWS are vulnerable to fast and complex speech motor control and language processing ability than CWNS. Thus, this study suggests that parents and therapists consider both the speech rate and the utterance length when talking with CWS.

요구용량 모델에 의하면 말더듬 아동의 비유창성은 외적, 내적 환경에 영향을 받아 나타나는 것으로 알려져 있다. 본 연구의 목적은 외적 환경 중 언어적인 환경(말속도, 발화길이 및 통사적 복잡성)의 변화에 따른 말더듬 아동과 일반아동의 비유창성 차이를 비교 분석하려고 한다. 연구대상은 4-6세 말더듬 아동 9명, 일반아동 9명이었다. 연구 과제로 문장 따라말하기 과제를 실시하여 말더듬 아동과 일반 아동의 비유창성 빈도를 구하였다. 두 그룹의 비유창성 차이를 분석한 결과, 발화길이를 조절했을 때 평균 말속도에서 말더듬 아동은 발화길이와 상관없이 일반 아동보다 비유창성이 더 많이 나타났다. 말속도를 조절 때 말더듬 아동은 빠른 말속도에서 일반아동보다 많은 비유창성을 보였다. 그리고 말속도와 발화길이를 조절했을 시 빠른 말속도에서 말더듬 아동은 발화길이와 상관없이 일반아동보다 높은 비유창성을 보였다. 통사적 복잡성을 조절했을 때는 복문에서 말더듬 아동이 일반아동보다 더 많은 비유창성을 보였다. 말더듬 아동은 말속도, 발화길이 그리고 통사적 복잡성에 따라 비유창성에 영향을 받는 것으로 나타났다. 이는 말더듬 아동은 말운동 조절 그리고 언어처리 능력이 일반아동보다 취약한 것으로 보인다. 따라서 임상에서 말더듬 아동 치료 시 치료사와 부모가 말속도와 발화길이를 아동의 수준에 맞춰 진행하는 것이 중요한 것으로 확인되었다.
