Effect of Feedback and Practice on Probabilistic Decision Making in Attention Deficit and Hyperactivity Disorder

November 16, 2015 updated by: Dr. Yehuda Pollak, Shaare Zedek Medical Center

The purpose of this study is to determine how feedback and practice affect decision making in adolescents with attention deficit and hyperactivity disorder.

Participants will have to choose between low and certain outcome and a higher but uncertain outcome, with or without serial feedback after each trial. Participants will perform the task twice to examine practice effects.
