Note. ADHD = attention-deficit/hyperactivity disorder; CV = coefficient of variation (SD/mean); MPT = mean pause time (ms); SD = standard deviation; TD = typically developing. All group comparisons are made after covarying for the Wechsler Intelligence Scale for Children – Fourth Edition (WISC-IV) Verbal Comprehension Index (VCI) and age.
