Here, we review the impact of three different ways of measuring technology use—total hours of media consumed, hours of video game play and number of media used concurrently—in a study surveying 156 eight-to-twelve year-old children. At stake is the question of whether different technology uses may have different effects, which could explain some of the past mixed findings.
