배경 및 목적: 어머니의 의사소통 행동 유형은 영유아의 의사소통 및 언어 발달에 영향을 미치는 요인 중 하나이다. 본 연구는 언어발달지체 영유아-어머니 상호작용 중에 어머니와 영유아의 의사소통행동 유형을 살펴봄으로써 어머니의 의사소통행동 유형이 언어발달지체에 미치는 영향을 살펴보고자 하였다. 방법: 언어발달지체 영유아-어머니 15쌍과 생활연령을 일치시킨 일반 영유아-어머니 15쌍 그리고 언어연령을 일치시킨 일반 영유아-어머니 15쌍, 총 45쌍의 영유아-어머니를 대상으로 하였다. 영유아와 어머니가 자유놀이와 책읽기를 하는 동안 자료를 수집하였으며, 녹화된 자료 중 10분을 발췌하여 분석하였다. 어머니의 의사소통행동은 주의환기, 설명하기, 지시하기, 질문하기, 피드백의 다섯 가지로, 영유아의 의사소통 행동은 요구하기, 언급하기, 모방하기, 질문하기, 반응하기, 무반응의 여섯 가지로 측정하였다. 결과: (1) 언어발달지체 어머니들은 생활연령 일치집단의 어머니들에 비해 설명하기는 유의하게 높은 빈도로, 그리고 피드백은 유의하게 낮은 빈도로 산출하였다. 언어연령 일치집단의 어머니들과는 유의한 차이가 없었다. (2) 언어발달지체 영유아가 생활연령 일치 영유아들에 비해 언급하기와 반응하기는 유의하게 낮은 빈도를 보였으며, 무반응 빈도는 생활연령 및 언어연령 일치 영유아에 비해 유의하게 많았다. (3) 영유아와 양육자간 의사소통 행동의 상관분석 결과, 세 집단 모두 양육자의 피드백과 영유아의 의사소통행동 간에 유의한 상관을 보였으며, 특히 언어연령일치 집단에서 유의한 상관이 많이 나타났다. 논의 및 결론: 본 연구는 언어발달지체 영유아 어머니의 의사소통행동 유형이 또래 영유아 어머니와 차이가 있으며, 어머니의 의사소통행동 유형이 영유아의 의사소통행동과의 관련됨을 제시하였다. 이러한 결과는 영유아 의사소통 평가 및 중재 시 어머니의 의사소통행동 유형도 함께 고려해야 함을 시사한다. Background & Objectives: It was reported that the communicative style of mothers affected communication development of their child. This study aimed to examine the communicative style of toddlers with developmental language delay and their mothers during play interaction. Methods: A total of forty-five toddlers ranging in age from 18 to 36 months and their mothers participated in this study including fifteen toddlers with developmental language delay (DLD) and their mothers, fifteen typical development toddlers matched for chronological age with the DLD individuals (CA controls) and their mothers, and fifteen typical development toddlers matched for language age with the DLD individuals (LA controls) and their mothers. Language samples of the toddlers and their mothers were collected during play interaction for 30 minutes. The mothers’ communicative behaviors were categorized into calling to attention, explaining, instructing, asking, and feedback, while the toddlers’ communicative behaviors were categorized into demanding, commenting, imitating, questioning, responding, and no response. Results: The mothers of the DLD individuals used more of the explaining function and less feedback than the mothers of the CA controls. The DLD toddlers produced less commenting and responding and more no response behaviors than CA controls. The feedback of the mothers in all of the groups were significantly related to the response of their toddlers. Discussion & Conclusion: The results of this study indicated that the communication style of mothers of DLD toddlers was slightly different than that of mothers of typical development toddlers.

소득수준과 언어수준에 따른 초등생의 읽기유창성 비교

This study explores reading fluency among elementary school students considering language level and family income(low SES). Forty eight students from 1st to 3rd grades participated in two paragraph reading tasks. Half of the children were from low income family and half of the children had low lexical knowledge. Reading fluency as in the number of correctly read syllables per minute, the total error frequency and error types were used to compare group differences. There were significant differences in the number of correctly read syllables per minute between two income groups and two language groups. There was a significant difference between low income group and non-low income group in total number of errors only when children"s lexical knowledge were low. There were no group differences in error types of repetition and omission. Substitution and insertion error seemed to reflect the total error pattern. These results imply the importance of early screening and early involvement for children with low lexical knowledge from low income family. Monitoring and early intervention will support these children"s reading development.

This study investigated changes in the prelinguistic vocal production of typically developing infants aged 5-20 months based on Stark Assessment of Early Vocal Development-Revised (SAEVD-R). Fifty-eight typically developing infants participated in the study, and they were divided into four age groups, 5-8 months, 9-12 months, 13-16 months, and 17-20 months of age. Vocalization samples were collected from infants" play activities and were classified into 5 levels and 23 types using SAEVD-R. The results revealed that the four age groups showed significant differences in production proportion of vocalization levels. Level 1, 2, 4, and 5 vocalizations exhibited significantly different across the four age groups. Level 3 was predominantly produced across every age group. Therefore, the vocalization level was not significantly different across the four age groups. Especially, vowels in Level 3 vocalization predominantly produced across all ages during a long period. Also, significant increases in the proportion of Levels 4 and 5 occurred after 9 months, which suggested that the production of cannonical syllables is a key indicator of advancement in prelinguistic vocal development. The results have clinical implication in early identification and speech-language intervention for young children with speech delays or at risk.

본 연구는 자발화 분석을 통해 음운, 의미, 구문, 형태론을 나타내는 객관적인 지표를 구해 월령집단과 성별에 따라 다른지 살펴보면서 2세 한국아동의 말-언어발달 특성을 자세히 살펴보았다. 또한 아동의 자발화 분석을 용이하게 하기 위해 개발된 한국어 발화 분석기(Korean Language Analysis, KLA) 프로그램을 이용해서 객관적인 측정치를 제시하면서 프로그램의 효율성을 소개하고자 하였다. 방법: 출생과 발달상의 특이사항이 없는 생후 24-30개월 된 일반아동 21명, 생후 31-36개월 된 일반아동 23명으로부터 50 발화를 수집하여 분석하였다. 객관적인 말 지표로서 자음목록, 음절구조 유형 수, 평균음운길이, 단어단위 근접률, 단어단위 정확률, 자음정확도를 분석하였다. 언어지표는 한국어 발화 분석 프로그램을 이용하여 서로 다른 낱말 수, 총 사용 낱말 수, 평균형태소길이, 평균낱말길이를 분석하였다. 결과: 2세 전반과 후반의 월령집단과 성별에 따라 말 특징을 살펴본 결과 평균음운길이를 제외한 모든 측정치에서 2세 전반과 후반 아동이 유의미한 차이를 보였다. 언어 특징을 나타내는 측정치인 서로 다른 낱말 수와 총 낱말 수, 평균낱말길이 면에서 월령집단별 유의미한 차이가 관찰되었다. 성별 간 차이는 모든 말-언어 측정치에서 유의하지 않았다. 논의 및 결론: 본 연구결과, 자발화 분석을 통한 2세 아동의 객관적인 자료는 말-언어발달지연 및 의사소통장애 여부를 평가할 때 기초자료로 활용될 수 있을 것이다. Objectives: This study obtained quantitative measures reflecting phonological, semantic, syntactic, and morphological aspects of language in Korean two-year-old children from analysis of spontaneous utterances. The study investigated whether there were differences of speech-language development patterns between children age 24-30 months and 31-36 months and between boys and girls based on the aforementioned measures. Methods: Twenty-one typically developing children age 24-30 months and 23 typically developing children age 31-36 months participated in the study. Fifty utterances were collected from the children’s interaction with their mothers and analyzed. Consonant inventory, syllable structure, phonological mean length of utterance (PMLU), phonological word proximity (PWP), phonological word correction (PWC), and percentage correct consonants (PCC) were obtained as speech measures. The number of different words (NDW), number of total words (NTW), mean length of utterances in morphemes (MLUm), and mean length of ut¬terances in words (MLUw) were analyzed as language measures using the Korean Lan¬guage Analysis program. Results: All the speech measures except for PMLU showed signifi¬cant differences between the children age 24-30 months and 31-36 months. NDW, NTW, and MLUw exhibited significant differences between the two age groups, but MLUm did not show a significant difference. There were no significant differences among any of the speech and language measures between boys and girls. Conclusion: These speech and language measures from analysis of spontaneous utterances can be used as references in identifying speech-language development delay and communication disorders in two-year-old children.
