Video game addiction (VGA) is associated with cognitive problems, particularly deficits in inhibitory control. The present study aimed to investigate behavioural responses and event-related potential associated with specific response inhibition using the cued Go/NoGo task to examine the effects of VGA on brain activity related to response inhibition. Twenty-five individuals addicted to video games (action video games) and 25 matched healthy controls participated in the study. The results showed that the VGA group had significantly more commission error in the NoGo trials and faster reaction time in the Go trials compared with the control group. The event-related potential analyses revealed significant reductions in amplitudes of N2 cue and N2 NoGo in the VGA group. While there was no significant difference between the N2 amplitudes of the Go and NoGo trials in the VGA group, the control group had a larger N2 amplitude in the NoGo trials. These results indicate that VGA subjects have difficulties in the early stages of response inhibition, as well as some level of impairment in proactive cognitive control.
视频游戏成瘾（VGA）与认知问题有关，特别是在抑制控制方面存在缺陷。本研究旨在使用线索 Go/NoGo 任务来研究与特定反应抑制相关的行为反应和事件相关电位，以探讨 VGA 对与反应抑制相关的大脑活动的影响。25 名沉迷于视频游戏（动作视频游戏）的个体和 25 名匹配的健康对照组参加了研究。结果表明，与对照组相比，VGA 组在 NoGo 试验中出现更多的错误反应，在 Go 试验中的反应时间更快。事件相关电位分析显示，VGA 组的 N2 线索和 N2 NoGo 的振幅显著降低。虽然 VGA 组的 Go 和 NoGo 试验的 N2 振幅之间没有显著差异，但对照组在 NoGo 试验中具有更大的 N2 振幅。这些结果表明，VGA 受试者在反应抑制的早期阶段存在困难，以及在主动认知控制方面存在一定程度的损伤。
