FPS players’ parietal responses to the ignored 3 Hz flicker were predictive of hit rate and were positively correlated with it, indicating distractor suppression. The following are the most significant results: RPG players’ parietal responses to the attended 8.6 Hz flicker were predictive of hit rate and were positively correlated with it, indicating attentional signal enhancement. We computed signal-to-noise ratio (SNR) of SSVEPs and used partial least squares regression to model hit rates, SNRs and their relationship at 3 Hz and 8.6 Hz. The largest differences in hit rate, between groups, occurred when four regions were simultaneously attended. Hit rates decreased with increasing presentation rates and number of regions, with the FPS players performing on average better than the RPG players. ![]() Search difficulty was varied along two dimensions: number of adjacent attended and ignored regions (1, 2 and 4), and presentation rate of novel search arrays (3, 8.6 and 20 Hz). ![]() ![]() We measured both successful detections (hit rates) and steady-state visually evoked EEG potentials (SSVEPs). We investigated the psychophysical and neurophysiological differences between fast-action video game players (specifically first person shooter players, FPS) and non-action players (role-playing game players, RPG) in a visual search task.
