Lexical prosodic representation and access in Japanese children with developmental dyslexia.

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.

Development of a reading difficulty questionnaire for adolescents in Japanese.

Background: Dyslexia is a neurodevelopmental disorder which occurs in childhood but continues to influence academic and occupational function in adulthood. Recently, a Japanese dyslexia questionnaire and diagnostic procedure was established for primary school children. However, there is currently no procedure for the diagnosis or screening of dyslexia in individuals at or above junior high school age; accordingly, we aimed to develop a questionnaire to screen for reading difficulties in those individuals.
