초기 단계의 읽기 및 음운 능력과 청각 시간처리 능력의 관계 = The Relation of Auditory Temporal Processing and Early Reading Ability and Phonological Awareness

다국어 초록 (Multilingual Abstract)

The present study was designed to explore the relationship of auditory temporal processing and early reading ability and phonological processing in 123 preschoolers who were 4 to 6 year old. Auditory temporal processing was measured by administering ‘frequency modulation(FM) detection’ and ‘auditory temporal order judgment(ATOJ)’ tasks. Also, non-verbal IQ, phonological awareness and reading accuracy were administered. The results showed that preschooler's FM detection threshold and ATOJ score were significantly correlated with reading accuracy and phonological awareness. Multiple regression analysis revealed that FM detection threshold significantly predicted reading accuracy and phonological awareness even after controlling for the effects of age and nonverbal intelligence. These results suggested that the auditory temporal processing is a contributing factor in early reading and phonological development.

본 연구는 미취학 아동에서 청각 시간처리 능력과 읽기 능력, 음운처리 능력간의 관련성을 밝혀보고자 수행되었다. 만 4, 5, 6세 유치원 아동 123명을 대상으로 청각 시간처리 능력을 측정하기 위해서 청각 시간순서 판단과제와 2Hz 청각 주파수변조 과제를 실시하였고, 레이븐 지능검사, 음운인식 검사, 단어읽기 검사를 실시하였다. 분석결과, 청각 시간순서 판단과제와 2Hz 청각 주파수변조 탐지역치는 읽기정확성과 음운인식과 유의한 상관을 보였다. 또한 2Hz 청각 주파수변조 탐지역치는 지능과 월령의 영향을 통제하여도 읽기 능력의 발달에 유의한 설명력을 가졌다. 청각 시간처리 능력과 음운처리 능력간의 관계를 분석한 결과, 2Hz 청각 주파수변조 탐지역치와 청각 시간순서 판단과제는 음운인식과 유의한 상관을 보였다. 청각 주파수변조 탐지역치는 연령과 읽기를 통제하여도 음운인식에 대해 유의한 설명력을 지녔다. 이러한 결과들은 청각 시간처리 능력이 읽기발달과 음운처리의 발달에 중요한 변인으로서 영향을 미친다는 것을 지지해주며, 읽기 발달에 대한 청각 시간처리 능력의 영향에 대한 가설이 한글과 같은 비서구권의 언어에도 일반화될 수 있음을 제안해준다. 또한 청각 시간처리 능력은 미취학 아동에서 읽기문제를 조기에 탐지하는데 중요한 변인으로서 앞으로의 읽기연구에서 좀 더 탐색되어야 할 필요성을 시사해주고 있다.
