简要总结
The primary aim of this study is to evaluate the therapeutic potential of real-time functional magnetic resonance imaging (MRI) neurofeedback in alleviating internet gaming disorder (IGD) symptoms by training individuals with such symptoms to down-regulate the activity in their reward-processing-related midbrain regions.

研究组 & 干预措施
Experimental neurofeedback intervention
In an approximately 30-minute training session, participants receive activity feedback from a midbrain region involved in reward processing and gaming addiction. Feedback will be presented in the form of a thermometer/bar in the middle of the screen and updated every two seconds. They will be trained to down-regulate the activity in this region with the help of this feedback using cognitive strategies. This down-regulation training is believed to be beneficial to addictive behaviors by the investigators.
干预措施: Neurofeedback training (Device)
Sham feedback intervention
In an approximately 30-minute training session, participants receive activity feedback from a brain region irrelevant to reward processing or gaming addictive behavior. The feedback presentation form and task instructions will be the same as for the experimental group. Based on the functional role of the feedback region, the investigators do not believe this feedback training will change the addictive behaviors of the participants who receive this intervention.
干预措施: Sham feedback training (Device)
