摘要

有大量证据表明,接触暴力媒体会增加攻击性思维和行为,部分原因可能是前额叶皮层介导的抑制机制发生了改变。过去的研究表明,短时间玩暴力电子游戏会减少抑制过程中随后的前额叶活动,但长期玩游戏的影响尚不清楚。为了评估广泛的电子游戏对大脑活动的影响,具有有限电子游戏经验的年轻成年男性(n=49;18-29岁)在功能磁共振成像中连续3周执行了一项允许/不允许的任务。基线扫描后,这些男性被随机分配在接下来的一周内广泛玩暴力视频游戏(VG)或避免所有视频游戏(对照)。1周后,与对照样本相比,VG组右额下回和右小脑的抑制相关活动减少,自我报告的执行功能问题更高。与对照组相比,被分配进行第二周游戏的VG参与者在抑制过程中双侧前额叶活动也同样减少。然而,被分配在第二周避免游戏或进行认知训练游戏的VG参与者与对照组相比,表现出了类似的总体变化。这项研究提供了初步证据,表明长期玩电子游戏可能会在抑制过程中影响大脑功能,从而削弱对攻击行为的控制。

Decreased Prefrontal Activity During a Cognitive Inhibition Task Following Violent Video Game Play: A Multi-Week Randomized Trial
There is substantial evidence that exposure to violent media increases aggressive thoughts and behaviors, potentially due in part to alterations to inhibitory mechanisms mediated by prefrontal cortex. Past research has demonstrated that playing a violent video game for short periods decreases subsequent prefrontal activity during inhibition, yet the impact of long-term game play is unclear. To assess how extensive video game play impacts brain activity, young adult males (n = 49; ages 18–29) with limited video game experience performed a go/no-go task during fMRI for 3 consecutive weeks. Following a baseline scan, these men were randomly assigned to extensively play a violent video game (VG) or avoid all video game play (control) during the subsequent week. After 1 week, inhibition-related activity decreased in right inferior frontal gyrus and right cerebellum in the VG group, compared to the control sample, and self-reported executive functioning problems were higher. VG participants assigned to a second week of game play had similarly reduced bilateral prefrontal activity during inhibition, relative to the control group. However, VG participants assigned to avoid game play or play a cognitive training game during the second week demonstrated similar overall changes from baseline as the control group. This research provides preliminary evidence indicating how long-term video game play may impact brain function during inhibition, which may impair control of aggressive behavior.

期刊介绍: Psychology of Popular Media Culture ® is a scholarly journal dedicated to publishing empirical research and papers on how popular culture and general media influence individual, group, and system behavior. The journal publishes rigorous research studies, as well as data-driven theoretical papers on constructs, consequences, program evaluations, and trends related to popular culture and various media sources. Although the journal welcomes and encourages submissions from a wide variety of disciplines, topics should be linked to psychological theory and research.
