Summary

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

Detailed 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.

Conditions

• Internet Gaming Disorder

Interventions

Type	Name	Description
PROCEDURE	EABM training	The training aims at associating gaming pictures with negative words and pictures of healthy activities with positive words. Gaming pictures are always presented with a pair of negative words. Pictures of healthy activities are always presented with a pair of positive words. Each picture is presented with a fixed pair of words. Participants will be instructed to select one word to get the most monetary reward. Specifically, in response to each gaming picture, selecting one word will have a 70% chance to get a monetary reward and the other word will have a 30% chance to get a monetary reward. A similar rationale applies to the pictures of healthy activities. The reward setting will help consolidate target associations. Each training session includes 300 times/trials of each type of association, presented in pseudorandom way. The whole training includes 6 training sessions. Participants will receive one training session every days.
PROCEDURE	sham training	In the control group, neutral words instead of emotional words are used. All other settings are the same with those in the intervention group
