Abstract

Developmental dyslexia is traditionally defined as a discrepancy between reading ability and intelligence in children receiving adequate reading tuition. The possible existence of dyslexic subtypes has intrigued the researchers and practitioners for nearly a century. The aim of this research was to study the classification of subtypes of developmental dyslexia in Persian speakers.
This research was cross-sectional study: which multi stage sampling method was used. (I)
The subjects were selected from Persian speaking second graders of elementary schools in Tehran through using Diagnostic Reading Test (Shirazi & Nilipour,1381). The randomly selected subjects were given reading and writing tasks to determine the subtype of dyslexia in each case. Based on the results of the statistical analysis of the data (Independent T-test, Pearson correlation and Partial correlation) the dyslexic features of each subtype were determined. The results of this study indicated that most errors in word writing were visual and in text reading were rejection errors. These findings are consistent with theories that consider dyslexia as a syndrome which has different varieties and not different categories.
