본 연구는 음운인식 훈련이 읽기장애 아동의 결손된 뇌 영역의 활성화 정도를 회복시키는가에 대한 사례를 제시하기 위해 이루어졌다. 본 연구를 위해 1명의 읽기장애 아동을 대상으로 음운인식 훈련을 실시하기 전과 후에 기능적 자기공명 영상 장비를 이용하여 단어와 비단어 읽기 과제를 수행하는 동안의 뇌영상을 촬영하여 비교하였다. 실험 결과 음운인식 훈련을 받은 후 단어 음독 과제를 수행할 때는 좌반구는 하전두회의 판개부, 중측두회, 하전두회의 삼각부, 중심후회가 우반구는 소뇌 제 2다리가 사전 검사에 비해 더 많이 활성화되었다. 비단어 음독시는 좌반구의 중측두회와 전대상다발, 중전두회의 안와부, 그리고 중후두회와 우반구의 중후두회가 사전 검사의 뇌 영상에 비해 더 많이 활성화되었다. 이와 같은 연구 결과는 음운인식 훈련이 읽기에 관여하는 뇌영역의 활성화에 영향을 미쳤음을 보여주는 것이다.
The purpose of this study was to investigate the effects of Phonological Awareness Training on brain activation profiles of a child with RD. A child with RD was tested on two reading tasks (words vs. pseudo-words) and re-tested on the same tasks after 24 sessions of Phonological Awareness Training. The child's brain profiles were then compared. The results measured after Phonological Awareness Training are as follows: (1) In word reading tasks, the test subject showed increased activation of left inferior frontal (pars opercularis), middle temporal, inferior frontal (pars triangularis), postcental, and right cerebellum crus 2. (2) In pseudo-word reading tasks, the test subject showed increased activation of left middle temporal, anterior cingulum, middle frontal (pars orbitalis), middle occipital, and right middle occipital. These results suggest that phonological awareness training might affect the development of neural systems in key reading areas.
