To overcome this limitation, the current study focuses on the comparison between IGD subjects and recreational Internet game users (RGU) who play online games recreationally but do not develop dependence. Data from 40 RGU and 30 IGD subjects were collected while they were performing an event-related cue reactivity task in the fMRI scanner. The results showed that the IGD subjects were associated with enhanced activation in the left orbitofrontal cortex (OFC) and decreased activation in the right anterior cingulate cortex (ACC), right precuneus, left precentral gyrus and right postcentral gyrus in comparison with the RGU subjects. OFC is involved in reward evaluation and ACC is implicated in executive control function based on previous researches. Moreover, the activation of OFC were correlated with the desire for game-playing. Thus, the higher activation in OFC might suggests high desire for game playing, and the lower activation in ACC might indicates impaired ability in inhibiting the urge to gaming-related stimuli in IGD subjects. Additionally, decreased activation in the precuneus, the precentral and postcentral gyrus may suggest the deficit in disentangling from game-playing stimuli. These findings explain why IGD subjects develop dependence on game-playing while RGU subjects can play online games recreationally and prevent the transition from voluntary game-playing to eventually IGD.</dcterms:abstract> <dc:contributor>Liu, Xiaoyue</dc:contributor> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/39665"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2017-07-26T13:58:25Z</dc:date> <dc:contributor>Dong, Guangheng</dc:contributor> <dc:creator>Wang, Lingxiao</dc:creator> </rdf:Description> </rdf:RDF>
