An action video game modifies visual processing

In this editorial, the author discusses the article by Green and Bavelier on action video games modifying visual processing. Indeed, it has been emphasized that playing a video game markedly improves subject performance on a range of visual skills related to detecting objects in briefly flashed displays (such as baggage screeners to pick out suspicious objects from cluttered suitcases). Green and Bavelier have provided evidence that habitual video game players exhibit superior performance relative to non video game players on a set of benchmark visual task that tested the ability to process cluttered visual scenes and rapid stimulus sequences. These results suggest that action-video-game playing is capable of altering a range of visual skills. They also demonstrated that this advantage is not a result of self-selection (i.e. not because subjects with superior visual abilities tend to prefer playing video games). Subjects with little or no video gaming experience showed significant improvement in the benchmark task after playing just ten hours of a video game. In this editorial, the author attempts to explain why video game playing modifies visual processing. Increased attentional resources and changes in preattentive processing are among the theories suggested.—Valérie Biousse</P> http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png American Journal of Ophthalmology Elsevier
