Dyslexia speed problems in a transparent orthography.

This study was intended to help clarify the nature of dyslexia in Spanish. A sample of 30 children, 8 to 16 years old, participated in this study. Dyslexic children were compared to two control groups, a chronological age-matched control group and a reading level-matched control group. Measures included nonword and pseudohomophone reading (phonological procedure), homophone choice (orthographic procedure), and phonological awareness tasks (syllabic, intrasyllabic, and phonemic level). For each task, accuracy (error percentage) and performance time were measured. Results showed a deficit in the dyslexic group on all the tasks, which was more evident when time was considered. With the results consistent with studies in other transparent orthographies such as Italian and German, speed problems seem to be more evident and relevant than accuracy problems in Spanish dyslexic children.
