Conditions
Summary
This study aims to investigate the intervention effects of navigated repetitive transcranial magnetic stimulation (rTMS) on craving regulation in individuals with internet gaming disorder (IGD). The primary objectives include: (1) examining the impact of navigated rTMS over the dorsolateral prefrontal cortex (DLPFC) on the gaming cravings, and craving regulation capacity; and (2) exploring the potential neural mechanisms by which rTMS over the DLPFC improves craving intensity, and craving regulation ability.

Interventions
During real rTM session, participants will perform the regulation of craving (ROC). In the rest phase, participants need to relax and rest. In the ROC task, participants will regulate craving elicited by gaming pictures using cognitive reappraisal. During the task, reaction times (RTs) and craving scores wil be recorded.
During the sham rTMS session, participants will perform the regulation of craving (ROC). In the ROC task, participants will regulate craving elicited by gaming pictures using cognitive reappraisal. During the task, reaction times (RTs) and craving scores wil be recorded.
