Naming speed in children with and without cognitive disengagement syndrome and associations with reading comprehension

s = 0.31-0.50). Effects for RAN Numbers, RAN Letters, and RAS 3-Set were robust to control of family income, ADHD medication use, processing speed, and ADHD inattentive symptom severity. RAS 3-Set scores moderated the association between CDS and WIAT-III Reading Comprehension scores such that CDS status was associated with poorer reading comprehension performance only at low (slower) and mean naming speed performance but not at high (faster) performance. This study provides new evidence linking CDS to slower naming speed performance beyond demographic characteristics, processing speed, and ADHD symptoms. Findings suggest that naming speed may be deficient in children with CDS, which may exacerbate reading difficulties. Implications for assessment and intervention as well as recommendations for future research are discussed.
