Neuroscience. Video game images persist despite amnesia.

On page 350, researchers report the results of new work in which they used the computer game Tetris--which involves using spatial reasoning to slot falling blocks strategically into place--to study how the brain reviews what it has learned. The researchers found that people who have just learned to play Tetris have vivid images of the game pieces floating before their eyes as they fall asleep, a phenomenon the researchers say is critical for building memories. Much more surprisingly, the team also found that the images appear to people with amnesia who have played the game--even though they have no recollection of having done so.

Effect of action video games on the spatial distribution of visuospatial attention.

The authors investigated the effect of action gaming on the spatial distribution of attention. The authors used the flanker compatibility effect to separately assess center and peripheral attentional resources in gamers versus nongamers. Gamers exhibited an enhancement in attentional resources compared with nongamers, not only in the periphery but also in central vision. The authors then used a target localization task to unambiguously establish that gaming enhances the spatial distribution of visual attention over a wide field of view. Gamers were more accurate than nongamers at all eccentricities tested, and the advantage held even when a concurrent center task was added, ruling out a trade-off between central and peripheral attention. By establishing the causal role of gaming through training studies, the authors demonstrate that action gaming enhances visuospatial attention throughout the visual field.

Video game epilepsy in the twentieth century: a review.

INTRODUCTION: Visually evoked seizures have been reported for almost 2,000 years. This source of seizure activity, however, seems to have increased recently with the advent of new technologies used for television and computer games. METHODS: The present paper reviews the literature regarding this interesting phenomenon. RESULTS: After our review, it does appear that visually evoked seizures have increased in frequency during the twentieth century. CONCLUSIONS: We believe that knowledge of visually evoked seizures may aid neuroscientists in further exploration of the pathophysiology of seizure activity and its related preventive measures. Further studies are necessary to prove the etiology of such seizure activity.

Media ratings for movies, music, video games, and television: a review of the research and recommendations for improvements.

This article review is organized by studies that are relevant for testing the reliability and validity of ratings systems. Specifically, the interrater reliability, consistency, temporal stability, content validity, construct validity, and criterion validity of media ratings systems are reviewed. Data that are related to testing the "forbidden fruit" and "tainted fruit" hypotheses also are reviewed. Several changes are recommended to improve the ratings systems, including the creation of a universal ratings system that could be applied equally to all media. The research reviewed here can provide a guide for how to construct a reliable, valid, and more useful ratings system. This is important because the decisions that parents make regarding their children's media use can be only as good as the information to which the parents have access.

Use of a video-game/stripe presentation for amblyopia therapy.

A variation of "stripe therapy" for amblyopia is described, using a composite video presentation of a television game with horizontal or vertical moving stripe backgrounds. The initial study has been carried out with two groups of amblyopic subjects, one group exposed to stripe backgrounds while playing the television games, and a small control group playing the games without any striped backgrounds. A wide range of results was obtained over several weekly exposure sessions, from possibly significant improvement to essentially no change in visual acuity. The results obtained from the group exposed to striped backgrounds do not appear to be markedly better than those obtained from the control group.
