About

This project aims to investigate (1) the efficacy of emotional association bias modification (EABM) training on internet gaming disorder (IGD); (2) the underlying neural mechanisms of such efficacy

Full description

As with the efficacy, the experiment aims to test whether EABM training will reduce positive emotional association bias towards gaming, compulsive choice of gaming pictures, cue-induced craving for gaming, the severity of gaming behaviors in individuals with IGD.

As with the underlying neural mechanisms, the experiment aims to test whether EABM training will alter the activation of reward circuits in response to gaming pictures, the activation of executive control network (mainly refering to the prefrontal cortex) regarding regulation ability for craving and response inhibition ability.
