Description:

participants have to complete the picture assessment task ; Approach-avoidance Task(AAT) and cue-induced task in the fMRI；data on game-craving level, game hours, the ability of self-control and emotion regulation are also collected. Half of the participants will be random-assigned into the CBM training group; Each participant will do these task twice( e.g. Before training and after training)

Treatment:

Procedure: CBM training

Sham training
