This study examined between-group differences in planning of 9 grade 6 children with attention deficit hyperactivity disorder (ADHD) who were on stimulant medication and a matched comparison group of 9 without ADHD on a complex problem solving task. Both computer and verbal protocol data was analyzed to obtain information both about the participants' global performance indicators (accuracy and speed of performance) and their planning process. Consistent with existing literature on medication effects, no between-group differences in performance accuracy and speed were observed. Protocol analyses, however, indicated that planning processes were not identical for the two groups. More particularly, children with ADHD favoured a planning-in-action approach whereas the comparison group favoured a local advance planning approach. Implications of these findings for the current discussion about the medication effects are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
