The current study examined the effects of brief video game exposure on cognitive control using event-related potentials (ERPs). Cognitive control was assessed by ERP components associated with the ability to detect (N2) and resolve (SP) conflict when the conflict was either expected or unexpected. After playing either an action or strategy video game, participants completed a counting Stroop task while ERPs were recorded. The proportion of congruent to incongruent trials was manipulated across blocks to create conditions where conflict was expected or unexpected. While visual inspection of the behavioral and neural data revealed interesting patterns by video game, none of those effects were statistically significant. This is consistent with some previous work and inconsistent with other published data, suggesting that there is still much to learn about the relationship between cognitive control and video game experience.
本研究采用事件相关电位（ERP）考察了短暂视频游戏暴露对认知控制的影响。通过与检测（N2）和解决（SP）冲突的能力相关的 ERP 成分来评估认知控制，当冲突可预期或不可预期时，都会产生这种能力。在玩动作或策略视频游戏之后，参与者在记录 ERP 的同时完成了计数斯特鲁普任务。通过在各块中改变一致和不一致试验的比例，创建了可预期或不可预期冲突的条件。虽然对行为和神经数据的直观检查显示出了视频游戏的有趣模式，但这些效果都没有统计学意义。这与一些先前的工作一致，与其他已发表的数据不一致，表明在认知控制和视频游戏经验之间的关系方面仍有许多需要了解。
