Cogmed is a computer-based cognitive training program that consists of rotating exercises that train attention and working memory. The exercises are presented in a child-friendly, game-like format. Training is completed at home in 25 sessions for 15-30 minutes each weekday for 5-9 weeks. A research team member serves as a coach who monitors progress and provides support through weekly phone calls with study participants and their parents/guardians. Information regarding compliance and performance is tracked over the internet and used to tailor feedback during weekly telephone coaching.
