Objective
Deficits in working memory tasks have been widely documented in Attention Deficit Hyperactivity Disorder (ADHD) studies. The aim of this study is to evaluate the effects of working memory load in impulsivity during decision-making processes. A delayed discounting (DD) paradigm was used, comparing children with ADHD and age matched controls.
Method
Thirty-two children equally divided with typical development or ADHD between 8 and 10 years of age were assigned to sessions of a dual-task paradigm. The first task was a forced dual choice between different amount of moneys at different time delay, while the second task was the repetition of a random series of digits with different lengths.
Results
Compared to peers with typical development, delayed discounting was significantly stronger in children with ADHD and for heavier memory load conditions. Furthermore, the memory load impact was stronger in children with ADHD compared to children with typical development.
Discussion
Results are discussed in terms of the relation between working memory load and decision-making processes.
