Participants who are randomized to the COG-AM intervention group will be asked to complete 30-minute computerized cognitive training (Lumosity cognitive training program) sessions during morning hours (between 09:00-12:00), for a total of 7 days or until hospital discharge, whichever comes first. Participants will complete cognitive training sessions in each of the following subdomains: memory, attention, problem solving, cognitive flexibility, and processing speed.
