Working Memory Training in College Students With Attention-Deficit Hyperactivity Disorder/Learning Disabilities

Study Overview
=================
Brief Summary
-----------------
The overall objective of the current study is to determine whether computerized Working Memory (WM) training will enhance WM capacity in college students with Attention Deficit Hyperactivity Disorder (ADHD)/Learning Disabilities (LD). There are also three additional objectives. The first is to determine whether improvements in WM will generalize to secondary outcome tasks, such as inhibitory control and planning. The second objective is to examine whether WM training will also ameliorate ADHD symptoms of inattention and hyperactivity. The last objective is to investigate whether improvements will be maintained at a two month follow-up period. It is expected that the computerized WM training program will enhance WM capacity in college students with ADHD. In addition, it is believed that these increases in WM capacity will also lead to improvements in other executive functions. It is also hypothesized that WM training will lead to a reduction in ADHD symptomology. Lastly, these improvements should be maintained at three month follow-up.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Behavioral: Cogmed|The Cogmed Working Memory Training Program will be used as the experimental program because of preliminary evidence indicating its effectiveness in enhancing WM and reducing behavioural symptoms of inattention/hyperactivity in children. This software-based training program was designed to improve WM abilities, particularly in children with ADHD or severe attention problems. Training is implemented with a software program (RoboMemo©). It includes a set of auditory verbal and visual-spatial WM tasks presented via computer. All tasks involve: maintenance of simultaneous mental representations of multiple stimuli, unique sequencing of stimulus order in each trial and progressive adaptation of difficulty level as a function of individual performance.|
