The present study investigated the brain-behavior relationships between cerebellar vermal volume, phonological processing, and verbal working memory in children with Reading Disability (RD) and Attention-Deficit/Hyperactivity Disorder (ADHD). It was hypothesized that there would be differences in inferior posterior vermal volume between those with and without ADHD. Individuals with and without RD were not expected to differ in posterior inferior vermal volume and an interaction in the RD/ADHD group was expected. Children with RD/ADHD were expected to have similar volumes to children who have ADHD. It also was hypothesized that inferior posterior vermal volumes would be correlated with verbal working and phonological short-term memory; anterior vermal volumes were hypothesized to be correlated with elision, and superior posterior vermal volumes were hypothesized to be correlated with rapid object and rapid letter naming. Results indicated that there were no group differences in posterior inferior vermal volume between children with and without RD as well as with and without ADHD. There were also no relationships between phonological processing and verbal working memory. The findings in this study were unexpected and suggest the need for further study between phonological processing, verbal working memory, and vermal volume in children with ADHD and RD.
