Examination of verbal memory and recall time in children with attention deficit hyperactivity disorder.

In this study 22 7- to 11-year-old children diagnosed with attention deficit hyperactivity disorder (ADHD) and 44 age-matched controls recruited from the same classrooms were given a 4-item delayed serial recall task using numbers or phrases. Although both groups showed similar recall accuracy rates, ADHD children required significantly longer times to retrieve and articulate their answers than children from the control group, regardless of age. The findings are discussed in relation to theories of executive function deficits in ADHD.
