whether video game experience led to greater task improvement, and whether the tasks affected by game experience differed depending on the type of video game. These questions were tested by examining whether expert and non-gamer performance differed on the tasks in the assessment battery, and second by testing within the game practice groups whether performance on the assessment battery tasks interacted with group (CONTROL, MOH, TETRIS, RON) and assessment session (Session1, Session 2, Session 3). To reduce the influence of within-participant outliers, we analyzed median rather than mean response times unless otherwise noted.
