The storage and/or automatic and accurate access of basic facts of addition from the long term memory seem to be impaired in children with Attention Deficit/Hyperactivity Disorder (ADHD). As a result, such group of students ultimately uses more immature counting procedures than their peers without the disorder. The aim of this study is to identify and describe the counting procedures and memory processes used by a group of 28 students, aged between 8 and 14 years old, with ADHD predominantly inattentive type (ADHD-PI) or combined type (ADHD-C). The results indicated that students with ADHD were still using counting procedures considered immature for the expected grade and that, among the memory processes, the decomposition was the most used one.
