In this narrated video, cognitive psychologist C. Shawn Green walks us through the astounding range of abilities, from contrast sensitivity to task-switching, that can improve as a function of playing first-person-shooter video games. If you already know something about perceptual decision making, particularly its modeling from a signal detection theory framework, think about whether the effects of action video-game playing that are illustrated here are best understood as boosting “momentary evidence”, “accumulated evidence”, both, or neither.
