Abstract:

Internet Gaming Disorder (IGD) has become one of the most prominent mental health concerns. Although prior studies have examined IGD performance in color-word conflict Stroop tasks, the processing characteristics underlying global-local conflict tasks remain poorly understood. This study investigated interference control capabilities in individuals with IGD using a global-local conflict task combined with fNIRS. Results revealed that in the control group, accuracy was significantly lower in the incongruent condition compared to the congruent condition, whereas no significant difference was observed across conditions in the IGD group. In the dorsolateral prefrontal cortex, the IGD group exhibited greater activation than the control group. Additionally, in the frontopolar and orbitofrontal regions, the control group exhibited greater activation during the incongruent condition than the congruent condition, while the IGD group showed no significant differences. Further correlation analyses revealed significant associations between task performance and brain activation. These findings suggest that IGD may exhibit enhanced processing efficiency in the global-local task. Changes in activation within the frontopolar and orbitofrontal regions may underlie this neural mechanism. Overall, this study provides novel insights into the cognitive mechanisms of individuals with IGD in the context of global-local interference tasks, contributing to a more comprehensive understanding of IGD.

摘要:

网络游戏成瘾(IGD)是当下最受关注的心理健康问题之一。以往研究多关注IGD在Stroop色词冲突任务上的表现,然而其在整体−局部冲突任务上的加工特点尚不清楚。本研究采用整体−局部冲突任务,并结合功能性近红外脑成像技术(fNIRS),考察IGD的干扰控制能力。结果发现,对照组在不一致条件下的正确率低于一致条件,IGD组在两条件下的正确率没有显著差异。IGD组在背外侧前额叶的激活高于对照组。此外,在额极和眶额叶,对照组在不一致条件下的激活大于一致条件,而IGD组在激活上没有显著差异。相关分析发现大脑激活与任务表现显著相关。结果表明,不涉及冲突时,背外侧前额叶的激活介导了IGD更高的认知投入从而促进了任务表现;涉及冲突时,额极和眶额叶的激活强度保持稳定,可能说明IGD对冲突的适应和自动化加工,进而促进了任务表现。
