Summary
Individuals with Internet gaming disorder (IGD) show a stronger automatic tendency to approach gaming cues. This bias is linked to specific brain activity patterns, suggesting underlying neuropsychological mechanisms.
Area of Science:
- Neuroscience
- Psychiatry
- Behavioral Science
Background:
- Internet gaming disorder (IGD) is associated with an approach bias towards gaming cues.
- The underlying neuropsychological mechanisms of this automatic action tendency in IGD are not well understood.
Purpose of the Study:
- To investigate the neuropsychological mechanisms of approach bias in individuals with IGD.
- To compare event-related potentials (ERPs) between IGD and healthy control (HC) participants during a gaming cue task.
Main Methods:
- Utilized the Stimulus-Response Compatibility (SRC) task to measure approach bias.
- Recorded event-related potentials (ERPs), specifically N100 and P300 amplitudes.
- Included 22 individuals with IGD and 23 healthy controls.
Main Results:
- The IGD group exhibited a significantly greater approach bias towards gaming cues compared to the HC group.
- IGD participants showed increased P300 amplitude and decreased N100 amplitude for game-approach versus game-avoid conditions.
- These ERP differences suggest altered motivational and conflict processing in IGD.
Conclusions:
- Enhanced integrated motivational value and increased stimulus-response conflict contribute to approach bias in IGD.
- Findings highlight potential targets for interventions in Internet gaming disorder.
- Longitudinal studies are recommended to further explore intervention strategies.
