Action video gaming can promote neural plasticity. Short-term monocular patching drives neural plasticity in the visual system of human adults. For instance, short-term monocular patching of 0.5-5 h briefly enhances the patched eye's contribution in binocular vision (i.e., short-term ocular dominance plasticity). In this study, we investigate whether action video gaming can influence this plasticity in adults with normal vision. We measured participants' eye dominance using a binocular phase combination task before and after 2.5 h of monocular patching. Participants were asked to play action video games, watch action video game movies, or play non-action video games during the period of monocular patching. We found that participants' change of ocular dominance after monocular patching was not significantly different either for playing action video games versus watching action video game movies (Comparison 1) or for playing action video games versus playing non-action video games (Comparison 2). These results suggest that action video gaming does not either boost or eliminate short-term ocular dominance plasticity, and that the neural site for this type of plasticity might be in the early visual pathway.
动作视频游戏可以促进神经可塑性。短期单眼遮盖可促进成人视觉系统的神经可塑性。例如，短期单眼遮盖 0.5-5 小时可短暂增强被遮盖眼在双眼视觉中的贡献（即短期眼优势可塑性）。在这项研究中，我们研究了动作视频游戏是否会影响正常视力的成年人的这种可塑性。我们在单眼遮盖 2.5 小时前后使用双眼相位组合任务测量参与者的眼优势。参与者被要求在单眼遮盖期间玩动作视频游戏、观看动作视频游戏电影或玩非动作视频游戏。我们发现，参与者在单眼遮盖后的眼优势变化在玩动作视频游戏与观看动作视频游戏电影之间（比较 1）或玩动作视频游戏与玩非动作视频游戏之间（比较 2）均无显著差异。这些结果表明，动作视频游戏既不会增强也不会消除短期眼优势可塑性，并且这种可塑性的神经部位可能在早期视觉通路中。
