网络游戏成瘾 认知功能损害 P300 N1
網絡遊戲成癮 認知功能損害 P300 N1
망락유희성은 인지공능손해 P300 N1
Internet-Game Addiction, Cognition deficit, P300, N1
许多研究证明，网络成瘾具有和物质依赖成瘾相同的成瘾症状：不仅有明显的社会功能损害，而且表现出抑郁、强迫、焦虑等精神症状。本研究采用事件相关电位技术．以网络游戏成瘾大学生为被试，探索了网络游戏成瘾者脑认知功能的变化。结果发现：①成瘾者听觉P300的波幅显著低于非成瘾者，说明网络成瘾者可能存在认知功能的损害；②成瘾者听觉N1的波幅显著高于非成瘾者．提示成瘾者可能存在感觉功能的易化．或者受到感觉寻求人格特质的影响。
許多研究證明，網絡成癮具有和物質依賴成癮相同的成癮癥狀：不僅有明顯的社會功能損害，而且錶現齣抑鬱、彊迫、焦慮等精神癥狀。本研究採用事件相關電位技術．以網絡遊戲成癮大學生為被試，探索瞭網絡遊戲成癮者腦認知功能的變化。結果髮現：①成癮者聽覺P300的波幅顯著低于非成癮者，說明網絡成癮者可能存在認知功能的損害；②成癮者聽覺N1的波幅顯著高于非成癮者．提示成癮者可能存在感覺功能的易化．或者受到感覺尋求人格特質的影響。

There is ample evidence that Internet addicts suffer from not only some obvious harms of social functions but also some psychopathic syptomic syptoms such as depression, compulsiveness, and anxiety, which are similar to the substance dependent addicts. Using the event-related potentials, the current study explored the brain function of college student internet-games addicts. The results showed that the amplitude of P300 was significantly smaller in the Internet addicts group than the normal group, which reflected that there was cognition dysfunction in the Internet addicts. Moreover, it was found that the amplitude of N1 related to the early auditory perception was remarkably larger in the Internet addicts than the normal group, which showed that the easy perception and/or the sensory seeking related to the personality might play an important role for the mechanism of Internet addiction.
