Experimental Intervention I: The Pathfinder training protocol will include supervised attentional regulation training sessions, either in-person or via the VA's video tele-health (VTEL) system, and home play of a computer game. Trainers will also call subjects between each supervised session to (i) check that patients are initiating home play (and help problem-solve or provide motivation, if necessary), and (ii) encourage transfer and generalization of learning, as per protocol. Home play will be configured to allow for about 35 minutes of play each day between supervised sessions. After the end of home game play, some additional time will be allowed for continued practice and application of trained skills in personal life.
