Abstract

Recent research indicates that awareness of the prosodic information present in spoken language could be an important factor for literacy development, and that adults with developmental dyslexia show impaired awareness of lexical prosodic information, while the phonological representations remain intact. We investigated lexical prosodic representation and awareness in Japanese children with and without developmental dyslexia. Lexical prosodic representation was investigated using a cross-modal fragment priming task, and awareness was examined using a fragment identification task. The task was modified for children by selecting words with higher familiarity and fewer trials. As a result, the same pattern of prosodic priming effects was observed between groups; lexical decision time was faster in the prosodic congruent condition than in the incongruent condition. In addition, accuracy and reaction time did not show group differences in the fragment identification task. Relationship between prosody and literacy development may differ between languages but the sample size were small in both groups. Further investigation with larger sample size is required.

日本发展性阅读障碍儿童的词汇韵律表征与获取
最近的研究表明,对口语中存在的韵律信息的认识可能是识字发展的一个重要因素,患有发展性阅读障碍的成年人对词汇韵律信息的意识受损,而语音表征保持不变。我们调查了有和没有发展性阅读障碍的日本儿童的词汇韵律表征和意识。使用跨模态片段启动任务研究词汇韵律表征,并使用片段识别任务检查意识。该任务针对儿童进行了修改,选择了熟悉度较高、试验次数较少的单词。结果,在各组之间观察到相同的韵律启动效应模式;韵律一致条件下的词汇决策时间比不一致条件下快。此外,准确度和反应时间在片段鉴定任务中没有显示出组间差异。韵律和识字发展之间的关系可能因语言而异,但两组的样本量都很小。需要进行更大样本量的进一步调查。

期刊介绍: DYSLEXIA provides reviews and reports of research, assessment and intervention practice. In many fields of enquiry theoretical advances often occur in response to practical needs; and a central aim of the journal is to bring together researchers and practitioners in the field of dyslexia, so that each can learn from the other. Interesting developments, both theoretical and practical, are being reported in many different countries: DYSLEXIA is a forum in which a knowledge of these developments can be shared by readers in all parts of the world. The scope of the journal includes relevant aspects of Cognitive, Educational, Developmental and Clinical Psychology Child and Adult Special Education and Remedial Education Therapy and Counselling Neuroscience, Psychiatry and General Medicine The scope of the journal includes relevant aspects of: - Cognitive, Educational, Developmental and Clinical Psychology - Child and Adult Special Education and Remedial Education - Therapy and Counselling - Neuroscience, Psychiatry and General Medicine
