摘要
目的：探讨虚证网瘾交往障碍者与正常人的情绪图片加工的差异以及虚证网瘾交往障碍者对于不同情绪性图片的注意偏向。方法：网瘾交往障碍者与正常对照组各12例。采用ERP技术,通过Go/Nogo研究范式检测两组被试者的情绪加工和抑制能力,分析ERP成分差异。结果：（1）网瘾交往障碍组的N2幅值显著降低,且潜伏期明显延迟,且网瘾交往障碍组不存在显著的N2Nogo刺激效应。（2）网瘾交往障碍组的P3幅值显著增强,却未表现出与正常组类似的Nogo刺激效应,中性和负性情绪刺激却使网瘾交往障碍组被试者诱发出比正性情绪刺激更大的P3。结论：网瘾交往障碍组被试者对于刺激的抑制反应和冲突监控能力与正常组相比较低。虚证网瘾交往障碍者对于负性情绪有较为显著的注意监测和反应抑制能力。
Objective：To explore the differences between people of deficient syndrome with communicating obstacle caused by internet addictions and the normal in emotional image processing,and the attention bias of people with communicating obstacle caused by internet addiction in different emotional images. Methods：Both the communicating obstacle group and the normal control group contained 12 cases. Using ERP technology,through the Go/Nogo paradigm,the emotional processing and rejection functions of the two groups were tested and the differences of ERP component were analyzed. Results：（1）The N2 amplitude in the communicating obstacle group was significantly reduced and the latency was significantly delayed. There was no significant N2 Nogo-stimulating effect in the communicating obstacle group.（2）The P3 amplitude in the communicating obstacle group is significantly enhanced,but did not exhibit the Nogo-stimulating effect which was similar to that of the normal control group. The P3 stimulated by the neutral and negative emotion in the communicating obstacle group was more obvious than that stimulated by the positive emotion. Conclusion：Faced with stimulations,the inhibition response ability and conflict monitoring capability of the communicating obstacle were lower than those of the normal control group,and people of deficient syndrome with communicating obstacle caused by internet addiction have more significant attention to monitoring and response suppression for negative emotions.
