Abstract：
Even though gaming and gambling bear similar problematic behavioral aspects, there are no recognizable neurophysiological biomarkers or features characterizing and/or distinguishing these conditions. A systematic review of the literature with a focus on methods was performed in PubMed, Scopus, Web of Science (Web of Science Core Collection), EBSCOhost Research Databases (APA PsycINFO; APA PsycArticles; OpenDissertations; ERIC) databases. Following search terms were used to search the databases: ERP, \"event related potential*\", EP, \"evoked potential*\", SS, \"steady state\", EEG, electroencephal*; gam*. Data about the participants (total number, gender, age), main aim of the study and information about the experimental setup (experimental task description, stimuli used, ERPs measured (latency windows and placement of the electrodes), process evaluated) was extracted. A total of 24 studies were revised (problematic gaming - 16, pathological gambling - 8). The experimental protocols could be grouped into 3 main target domains (Cue-reactivity, General Information processing and Reward Processes & Risk Assessment). Sample-related limitations (small sample sizes, gender differences, differences between the groups regarding potential confounding variables) and heterogeneity regarding the experimental tasks, implementation and interpretation reviewed. Gambling-related research is highly focused on the investigation of the reward-related processes, whereas gaming-related research is mostly focused on the altered aspects of more general information processing. A vast heterogeneity regarding the ERP experimental paradigms being used and lack of clear guidelines and standardized procedures prevents identification of measures capable to reliably discriminate or characterize the population susceptible to addictive behavior or being able to diagnose and monitor these disorders.
摘要：
即使游戏和赌博也有类似的问题行为方面，没有可识别的神经生理学生物标志物或特征表征和/或区分这些病症。在PubMed中对文献进行了系统的回顾，重点是方法，Scopus,WebofScience（WebofScience核心合集），EBSCOhost研究数据库（APAPsycINFO；APAPsycarticles；OpenDissertations；ERIC）数据库。以下搜索词用于搜索数据库：ERP，\"事件相关潜力*\",EP,“诱发电位*”，SS,\"稳态\",脑电图,脑电图*;gam*.有关参与者的数据(总数，性别,年龄),研究的主要目的和有关实验设置的信息(实验任务描述，使用的刺激，测量的ERP（潜伏期窗口和电极的放置），过程评估)被提取。总共修订了24项研究（有问题的游戏-16项，病态赌博-8项）。实验方案可以分为3个主要目标域(提示反应性，一般信息处理和奖励流程和风险评估)。与样本相关的限制(小样本量，性别差异，组间关于潜在混杂变量的差异)和关于实验任务的异质性，审查了实施和解释。与赌博相关的研究高度关注与奖励相关的过程的调查，而与游戏相关的研究主要集中在更一般的信息处理的变化方面。关于正在使用的ERP实验范例的巨大异质性以及缺乏明确的指南和标准化程序阻碍了识别能够可靠地区分或表征易受成瘾行为或能够诊断和监测这些疾病的人群的措施。
