Working Memory Training in ADHD (The Engage Study)

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). There are also four additional objectives. The first is to investigate whether the program's efficacy is impacted by the duration of the daily training sessions. The second is to determine whether improvements in WM will generalize to secondary outcome tasks, such as inhibitory control and planning. The third 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. The investigators will also be assessing healthy control participants,who will not be receiving treatment, but will be used as a basis of comparison with the ADHD participants, 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.
