目的探讨奖赏机制的皮层相关性及皮层失衡在网络成瘾易感性中的作用。方法采用网络成瘾量表（IAT）和人格特质量表（行为抑制系统（BIS）、行为激活系统（BAS））对28名被试进行测试。在Go-NoGo任务执行期间，记录了脑电图（EEG，α频段）和响应时间（RT），以响应不同的在线刺激：赌博视频，视频游戏或中性刺激。高IAT（大于50分，中度或重度网络成瘾）和低IAT（
Objective The present research explored the cortical correlates of rewarding mechanisms and cortical unbalance' effect in internet addiction (IA) vulnerability.Methods Internet Addiction Inventory (IAT) and personality trait (Behavioural Inhibition System, BIS; Behavioural Activation System, BAS) were applied to 28 subjects. Electroencephalographic (EEG, alpha frequency band) and response times (RTs) were registered during a Go-NoGo task execution in response to different online stimuli: gambling videos, videogames or neutral stimuli. Higher-IAT (more than 50 score, with moderate or severe internet addiction) and lower-IAT (
