Members of Mercy LIFE West Philadelphia are provided with transportation to the center for their normal activities. The members will participate in cognitive training sessions (computerized cognitive training vs. pencil-and-paper traditional cognitive training) 30-60 minutes per session, to total 480 minutes of training, within 12 weeks, at times that the participant has available throughout the day and week at the center. The researchers will keep a coded, detailed log of the session length to total the minutes completed throughout the 12 weeks. This flexibility of dosing (length, frequency, and duration) is at the request of Mercy LIFE West Philadelphia's Research Committee, to respect the members' medical and activity schedules.
