Introduction: The purpose of this study was to investigate the auditory selective attention in regular and dyslexic primary students.Methods: Research sample comprised 40 students from second, third and fourth grades of elementary school who were selected using cluster random sampling. Groups were matched in terms of age and sex. Research method was causal-comparative. Auditory attention test of competitive sentences was used as a tool of data collection. Besides, three objects (like watch) were used to determine the dominance of left or right ear.Results: The results of the test showed that auditory selective attention scores (right ear) in dyslexic students was significantly lower than regular students. Auditory selective attention scores (left ear) in dyslexic students was significantly lower than regular students as well. There was no difference between the groups in hearing dominance and both used right ear.Conclusion: Findings of this study are in line with those of the previous researches which showed dyslexic students had poor auditory selective attention and required an appropriate educational program to address their attention and educational problems.
