Neural underpinnings of internet gaming addiction tendency: The role of the limbic network in reward/punishment sensitivity and risky decision-making alterations

Abstract

Background and aims: Internet gaming addiction (IGA) is associated with altered reward/punishment sensitivity and risky decision-making. Nevertheless, the underlying neural mechanisms of such changes remain poorly understood. This study examined behavioral and neural predictors of IGA tendency with multiple datasets. Design: Observational study. Setting and participants: A total of 1142 university students [360 males and 782 females, mean (standard deviation) age of 18.75 (1.67) years] participated in the behavior-brain cross-sectional dataset (BBC). A subset of 303 BBC participants [71 males and 232 females, baseline mean age of 18.84 (1.72) years] participated in the behavior longitudinal ..
