Successful early reading and spelling acquisition depends on a number of different skills. Of considerable importance is phonological processing, which is the processing of acoustic signals with linguistic content. Three areas of phonological processing have been found to be most important for reading and writing competence: phonological awareness, naming speed, and phonological working memory. Research on these components suggests that specific interventions tailored to individual phonological processing deficits may prevent later dyslexia. Therefore, it appears mandatory that ear-nose-throat physicians have at least a basic knowledge of the theory of phonological processing. This will enable proper consultation with parents of affected children.
