On indexes of intelligence , the ARND group obtained lower Verbal Comprehension, Freedom from Distractibility and Processing Speed scores than non-ARND, while only Verbal Comprehension was significant nce parent intelligence was considered as a covariate.

These findings suggest that weaker verbal abilities are a defining characteristic of the ARND group for both the preschool and school-aged children.
