Abstract

the effects of cognitive fatigue. Despite this, there remain advantages to regularly playing action video games. In Study 1, VGPs were significantly better at multitasking on the MATB-II compared to the NVGPs. Further, VGPs also demonstrated superior multitasking when driving, as they made significantly fewer traffic violations compared to NVGPs when not fatigued. VGPs demonstrated eye-movements similar to those of expert drivers; however, this did not result in any difference in performance between the two groups. There was also some evidence of a positive effect of video game training, although there was no advantage of one training technique over the other. In Study 2, participants experienced the effects of cognitive fatigue to a lesser extent after video game training than compared to before training. Further, there was a significant improvement in multitasking performance after video game training, though as participants continued improving even at the three-month follow up test, it is unknown whether this was due to the video game training or due to practice effects on the MATB-II. Overall, despite improvements in sustained and divided attention performance from regular action video game playing or training, VGPs and trained-NVGPs are just as susceptible to the effects of cognitive fatigue as NVGPs.
