| Research Abstract |
To clarify the mechanisms of Rapid Automatized Naming (RAN) in the Japanese native speaker, we investigated the possibilities and limitations of RAN results in preschool 6-year-old Japanese children to estimate whether reading difficulties will be encountered after school entry. Also, to investigate the influence of speech-motor control and the automaticity of the phonological processing for RAN, we examined whether response latency until naming on the individual stimulus within RAN and the time required for oral-diadochokinesis by /pataka/ in 6-year-old preschool children differed between a control group (elementary school children in lower grades) and a disturbance group (children with developmental dyslexia). Results showed that the RAN result in 6-year-old preschool children was predictive of Kanji reading difficulty the lower grades of elementary school, especially in the third grade of elementary school with a probability of 83%. As the reason for the relatively high rate of prediction of a child being at risk of a reading disturbance, speech-motor control could not explain the RAN result. However, it was suggested RAN reflects the strength of automaticity of word recognition using multiple regression analysis.
