Abstract: Previous studies have identified that individuals with Internet Gaming Disorder (IGD) exhibit abnormal processing biases toward negative emotional stimuli, especially those associated with anger, in contrast to their healthy counterparts. Additionally, negative stimuli elicit excessive emotional arousal in individuals with IGD, yet they encounter challenges in effectively regulating negative emotions. These abnormalities in emotion processing capabilities play a pivotal role in the maintenance and development of IGD. Simultaneously, anomalies have been observed in brain regions linked with emotional processing in individuals with IGD, including the amygdala, anterior cingulate gyrus, insula, and portions of the prefrontal lobe. Future investigations could focus more on the group emotion processing in IGD, the temporal dynamics of emotion processing in IGD, strategies to enhance the emotional regulation abilities of individuals with IGD, and the emotional processing challenges faced by adolescents with IGD. Furthermore, designing and presenting emotional stimuli in diverse ways can be employed to achieve various research purposes. Meanwhile, the effects of the gender ratio of participants, as well as both long-term and short-term emotional states, on the results of emotional processing studies should also be taken into consideration.
