Video game play has been suggested to improve visual and attention processing. Nevertheless, while action video game play is highly dynamic, there is scarce research on how information is temporally discriminated at the millisecond level. This cross-sectional study investigates whether temporal discrimination at the millisecond level in vision varies across action video game players (VGPs; N = 23) and non-video game players (NVGPs; N = 23). Participants discriminated synchronous from asynchronous onsets of two visual targets in virtual reality, while their EEG and oculomotor movements were recorded. Results show an increased sensitivity to short asynchronies (11, 33 and 66 ms) in VGPs compared with NVGPs, which was especially marked at the start of the task, suggesting better temporal discrimination abilities. Pre-targets oculomotor freezing - the inhibition of small fixational saccades - was associated with correct temporal discrimination, probably revealing attentional preparation. However, this parameter did not differ between groups. EEG and reconstruction analyses suggest that the enhancement of temporal discrimination in VGPs during temporal discrimination is related to parieto-occipital processing, and a reduction of alpha-band (8-14 Hz) power and inter-trial phase coherence. Overall, the study reveals an enhanced ability in action video game players to discriminate in time visual events in close temporal proximity combined with reduced alpha-band oscillatory activities. Consequently, playing action video games is associated with an improved temporal resolution of vision.
视频游戏被认为可以改善视觉和注意力处理能力。然而，虽然动作视频游戏的玩法非常具有动态性，但对于毫秒级的信息如何进行时间分辨的研究却很少。本横断面研究调查了毫秒级的视觉时间分辨能力是否在动作视频游戏玩家（VGPs；N=23）和非视频游戏玩家（NVGPs；N=23）之间存在差异。参与者在虚拟现实中辨别两个视觉目标的同步和异步起始，同时记录他们的脑电图和眼动运动。结果表明，与 NVGPs 相比，VGPs 对短异步（11、33 和 66ms）的敏感性更高，这在任务开始时尤为明显，表明其具有更好的时间分辨能力。预目标眼动冻结——小注视性眼跳的抑制——与正确的时间分辨相关，可能揭示了注意力的准备。然而，该参数在两组之间没有差异。脑电图和重建分析表明，在时间分辨任务中，VGPs 中时间分辨的增强与顶枕叶处理有关，并且 alpha 波段（8-14Hz）功率和试验间相位相干性降低。总体而言，该研究揭示了动作视频游戏玩家在接近时间的视觉事件中进行时间分辨的能力增强，同时减少了 alpha 波段的振荡活动。因此，玩动作视频游戏与视觉的时间分辨率提高有关。
