Playing a first-person shooter (FPS) video game alters the neural processes that support spatial selective attention. Our experiment establishes a causal relationship between playing an FPS game and neuroplastic change. Twenty-five participants completed an attentional visual field task while we measured ERPs before and after playing an FPS video game for a cumulative total of 10 hr. Early visual ERPs sensitive to bottom-up attentional processes were little affected by video game playing for only 10 hr. However, participants who played the FPS video game and also showed the greatest improvement on the attentional visual field task displayed increased amplitudes in the later visual ERPs. These potentials are thought to index top-down enhancement of spatial selective attention via increased inhibition of distractors. Individual variations in learning were observed, and these differences show that not all video game players benefit equally, either behaviorally or in terms of neural change.
玩第一人称射击(FPS)视频游戏会改变支持空间选择性注意的神经过程。我们的实验在因果关系上确立了玩 FPS 游戏和神经可塑性变化之间的联系。25 名参与者在玩 FPS 视频游戏 10 小时的累积时间内完成了一个注意视野任务,同时我们测量了 ERPs 在游戏前后的变化。对自上而下注意过程敏感的早期视觉 ERP 受视频游戏影响很小,仅 10 小时。然而,玩 FPS 视频游戏且在注意力视野任务上表现出最大改善的参与者显示出后期视觉 ERP 振幅增加。这些电位被认为通过增加对干扰物的抑制来指示空间选择性注意的自上而下增强。观察到个体学习的差异,并且这些差异表明并非所有视频游戏玩家都能同等受益,无论是在行为上还是在神经变化方面。
