Pearson correlations were calculated between the overall mean RT (using the physical- and the name-identity task) and the ADHD index, inattention, hyperactivity, impulsivity, depression, anxiety, and stress. Only the ADHD index showed a positive trend with the overall mean RT (r = 0.17, p = 0.07). The finding indicates the higher the ADHD index score, the slower the RT performance. This was especially the case in the name-identity task (r = 0.20, p = 0.03) and more specifically for within hemisphere trials (r = 0.22, p = 0.01).
