【摘要】 目的 探讨网络游戏成瘾对情绪面孔效价及强度识别的影响。方法 采用情绪面孔识别范式分别从标准情绪识别和微表情识别考察网络游戏成瘾个体是否存在情绪面孔识别偏差。实验一：采用情绪面孔效价识别范式，比较网络游戏成瘾被试与非网络游戏成瘾被试在识别不同情绪效价下的差异。实验二：借助情绪面孔强度识别范式，比较被试群体在不同情绪强度下的差异。结果 被试识别正性情绪的反应时显著小于识别中性和负性情绪，识别正性和负性情绪的正确率显著高于识别中性情绪；随着情绪强度的变化，被试依然表现出了对正性情绪识别的偏好；相较于非网络游戏成瘾被试，网络游戏成瘾被试对正性情绪的识别正确率更高。结论 网络游戏成瘾个体在识别标准情绪刺激时并没有表现出明显的损伤，但该个体在识别微表情时表现出了更为强烈的对于寻求奖赏刺激的偏向。更多还原

【Abstract】 Objective To explore the effects of internet gaming disorder on emotional face valence and intensity recognition. Methods An emotional face recognition paradigm was used to examine whether there was emotional face recognition bias in internet gaming disorder individuals from standard emotion recognition and micro-expression recognition, respectively. For experiment 1, the differences between internet gaming disorder subjects and non-internet gaming disorder subjects in recognizing different emotional valences were compared by using emotional face valence recognition paradigm. For the experiment 2, the differences between the two groups under different emotional intensities were compared by using emotional face intensity recognition paradigm. Results The reaction time of the subjects for recognizing positive emotions was significantly shorter than those for recognizing neutral and negative emotions, and the correct rates for recognizing positive and negative emotions were significantly higher than those for neutral emotions. As the intensity of the emotions changed, the subjects still showed a preference for recognizing positive emotions. The internet gaming disorder subjects had a higher accuracy in recognizing positive emotions compared to non-internet gaming disorder subjects. Conclusion Internet gaming disorder individuals do not show significant impairments in recognizing standard emotional stimuli, but the individuals show a stronger bias toward reward-seeking stimuli in recognizing micro-expressions.更多还原
