Inhibitory Control in Problemat-ic-Internet-Inappropriate Content-Use under Negative Emotional Priming

采用问题性色情消费量表从623名异性恋男性被试中筛选出问题性网络色情使用(Problematic Internet Pornography Use, PPU)个体30名，健康对照组30名，利用情绪启动结合双选择Oddball任务诱导行为抑制控制的产生，比较两组被试对成瘾线索的抑制控制差异。结果：(1) PPU个体在负性情绪启动下有着更强烈的负性情绪体验，负性情绪启动后PPU组的负性情绪得分显著高于HCs组；(2) 两组被试偏差刺激下反应时均长于标准刺激，在两种刺激类型下，PPU组的反应时均大于HCs组，但差异不显著；(3) 两组被试负性情绪启动后偏差刺激的正确率均低于正性情绪启动。结论：PPU组在负性情绪启动下偏差刺激反应时和正确率表现均弱于正常对照组。此外，PPU组还表现出较高的焦虑和抑郁水平。这些发现揭示了PPU个体在负性情绪下存在抑制控制减弱，可能反映了他们使用色情内容作为应对负性情绪的策略。A Problematic Internet Pornography Use (PPU) scale was used to screen 30 individuals with PPU and 30 healthy controls (HCs) from 623 heterosexual male participants. An emotional priming task combined with a two-choice Oddball task was employed to induce behavioral inhibitory control, and the differences in inhibitory control over addiction cues between the two groups were compared. Results: (1) PPU individuals experienced more intense negative emotions under negative emotional priming, with the PPU group scoring significantly higher on negative emotions than the HCs group after negative emotional priming; (2) The response times of both groups to deviant stimuli were longer than those to standard stimuli. Under both stimulus types, the response times of the PPU group were longer than those of the HCs group, but the difference was not significant; (3) The accuracy rates for deviant stimuli were lower after negative emotional priming than after positive emotional priming in both groups. Conclusion: The PPU group exhibited weaker performance in response time and accuracy rate for deviant stimuli under negative emotional priming compared to the normal control group. In addition, the PPU group also showed higher levels of anxiety and depression. These findings reveal that PPU individuals exhibit weakened inhibitory control under negative emotions, possibly reflecting their use of pornographic content as a coping strategy for negative emotions.
