Dodd(2005)의 말소리장애 감별 진단 분류법에 따르면, 조음장애(speech disorder, SD), 음운지연(phonological delay, PD), 일관적 음운장애(consistent phonological disorder, CPD), 비일관적 음운장애(inconsistent phonological disorder, IPD)로 분류하였다. 말소리장애는 아동마다 말 산출시 나타나는 오류패턴이 다양하고, 언어능력 및 심각도 등 다양한 차이를 보인다. 대게 정상 말소리 발달 아동의 경우, 5-6세가 되면 말소리 오류 패턴이 사라지나, 지속적으로 말 산출에 어려움이 있는 말소리장애 아동의 경우, 언어, 인지 및 의사소통에서 어려움을 겪는다. 말소리장애 아동의 음운기억과 관련된 기존의 많은 연구는 음운정보에 초점이 맞춰져 있으며 의미정보 보유능력을 함께 살펴보는 연구는 미흡하다. 따라서 본 연구에서는 말소리장애 아동의 음운 정보를 기억하는 능력과 함께 어휘-의미정보를 보유하는 능력을 함께 살펴보고자 한다.
연구대상은 말소리장애 아동 17명과 일반아동 15명으로 하였다. 검사 순서는 선별검사로 PRES, U-TAP검사를 실시한 다음 연구 과제를 실시하였다. Roberts 등(2023) 연구진들이 사용한 음운작업기억과제를 참고하여 새로 제작하였다. 어휘 선정 및 그림 자료는 안진아(2016)를 참고하였으며, 숫자 배열은 음운유사성을 고려하여 과제를 제작하였다. 배열 수는 3배열, 4배열, 5배열로 구성하였고, 각 배열 수마다 10개의 항목을 제작하여 시각적 자극과 청각적 자극으로 과제를 제시하였다. 자료처리는 말소리장애 아동은 배열에서 어려움을 보인다는 여러 선행연구를 토대로 음운작업기억 과제의 점수는 류은주와 하지완(2018)의 배열점수를 참고하여 채점하였고, 의미정보 보유능력은 정오반응으로 점수를 채점하였다.

According to Dodd’s (2005) differential diagnostic classification of speech sound disorders (SSD), children with SSD are classified into articulation disorder (speech disorder, SD), phonological delay (PD), consistent phonological disorder (CPD), and inconsistent phonological disorder (IPD). Speech sound disorders are characterized by heterogeneous error patterns in speech production, as well as variability in language ability and severity across children. Typically developing children show a resolution of speech sound error patterns by the age of 5 to 6 years; however, children with persistent speech sound disorders continue to experience difficulties in speech production, which may extend to language, cognitive, and communicative domains. Previous studies on children with SSD have primarily focused on phonological memory, while relatively little attention has been paid to their ability to retain lexical–semantic information. Therefore, the present study aimed to examine both phonological working memory and lexical–semantic information retention in children with SSD.
Participants consisted of 17 children with speech sound disorders and 15 typically developing children. The assessment procedure included screening tests (PRES and U-TAP), followed by experimental tasks. The phonological working memory task was newly developed based on the task used by Roberts et al. (2023). Lexical selection and pictorial stimuli were adapted from Ahn (2016), and digit sequences were constructed with consideration of phonological similarity. The tasks consisted of three-, four-, and five-item sequences, with 10 items per sequence length, presented under both visual and auditory modalities. Data scoring for the phonological working memory task was conducted using sequence scoring criteria adapted from Ryu and Ha (2018), based on previous findings that children with SSD experience greater difficulty as sequence length increases. Lexical–semantic information retention was scored using accuracy-based responses.
The results were as follows. First, although mean performance differences were observed between groups across stimulus modalities, these differences were not statistically significant. Performance differed significantly according to sequence length, and a significant interaction effect between stimulus modality and sequence length was found. Children with SSD showed a marked decline in performance as sequence length increased. Second, although mean differences in lexical–semantic information retention were observed between the two groups, these differences were not statistically significant. Third, correlation analyses revealed that consonant accuracy was significantly correlated with lexical–semantic information retention (both visual and auditory) and with the visual working memory task. Language ability was significantly correlated with both visual and auditory working memory tasks. A significant correlation was also found between visual and auditory working memory tasks.
This study extends previous research by examining not only phonological working memory but also lexical–semantic information retention in children with speech sound disorders. The findings suggest that comprehensive assessment of both speech sound and broader speech–language domains may provide clinically useful information for identifying individual strengths and weaknesses in children with SSD.
