Determine the most effective rapid automatized naming tasks (RAN) for discrimination of Persian language students with and without dyslexia

The purpose of the present study was determining the most effective speed naming tasks for discrimination of Persian language students with and without dyslexia. In a causal-comparative design, all 77 students with dyslexia who had the criteria to enter the study were selected, and 77 normal students who were similar with the dyslexic group in terms of age, gender, and intelligence were also selected as available. Data was collected using a diagnostic Reading Test (Shirazi, & Nilipour, 2005), Raven Intelligence Test (Raven, 1956) and Rapid Automatized Naming Tasks (Denckla, & Rudel, 1976). To analyze the data, the independent T test and discriminative analysis method were used. Results show that students with dyslexia perform significantly less than normal students in rapid automatized naming tasks (p <0.0001); also, the coloring shape rapid automatized naming tasks was the most effective in distinctive students with and without dyslexia; therefore, rapid automatized naming tasks, especially coloring shape rapid automatized naming tasks, could be used to discrimination students with and without dyslexia.
