Participants were randomly assigned to either the music therapy group (n = 15) or a control group (n = 15). The music therapy intervention consisted of 12 weekly sessions, each lasting 45 minutes, focusing on active music-making and improvisation. The control group received no intervention. Processing speed was assessed using standardized cognitive tasks, including the Stroop Test and the Digit Symbol Substitution Test (DSST), administered before and after the intervention. Data analysis was conducted using paired t-tests and repeated measures analysis of variance (ANOVA).</p> <p><strong>Findings: </strong>Results indicated that children in the music therapy group showed significant improvements in processing speed compared to the control group, as measured by the DSST and Stroop Test. The music therapy group demonstrated faster reaction times and improved accuracy in cognitive tasks, with a medium to large effect size (Cohen’s d = 0.65). No significant changes were observed in the control group. Additionally, improvements in social skills and emotional regulation were reported by caregivers and teachers, suggesting that music therapy had broader benefits beyond cognitive performance.</p> <p><strong>Conclusion: </strong>The findings suggest that music therapy can significantly enhance processing speed in children with mathematical disorder. These results support the potential of music therapy as an effective intervention for improving cognitive functions and overall emotional well-being in this population.</p> https://www.maherpub.com/index.php/jndd/article/download/292/233
