摘要

While impaired decision-making and reduced impulsive control have been repeatedly reported in individuals with Internet Gaming Disorder (IGD), there was accumulating evidence that controlled gaming exposure may be beneficial in certain aspects of perceptual decision-making. This study aimed to investigate perceptual decision and metacognition processing in IGD applying a post-decision wagering paradigm and drift-diffusion modeling (DDM). Results demonstrated that individuals with IGD exhibited enhanced decision accuracy and elevated drift rates during perceptual decision-making. Yet, no group differences were observed in comparison of metacognitive ability and metacognitive bias, indicating preserved metacognition in IGD. Notably, drift rates were positively correlated with anxiety and depression symptoms in the IGD group, but was negatively correlated with general self-efficacy in healthy controls (HCs), indicating compromised self-regulatory capacity and maladaptive metacognitive resource allocation patterns in IGD individuals. These findings demonstrated enhanced performance and elevated evidence accumulation efficiency during perceptual decision-making, as well as preserved metacognitive abilities in individuals with IGD, suggesting gaming may induce certain cognitive enhancement during perceptual decision-making in clinically diagnosed IGD.
