摘要
网络成瘾作为一种行为成瘾,已成为严重影响人们心理健康的全球性问题.根据大脑发育的神经生物模型,揭示网络成瘾者奖赏和认知控制系统的神经机制是解决网络成瘾问题的关键,也是心理学研究的重大问题.行为研究探讨了网络成瘾具有高奖赏寻求和低认知控制特征;神经机制研究揭示了奖赏和认知控制系统的缺陷是网络成瘾行为的高风险因素;与药物成瘾的比较研究发现,网络成瘾有着独特的奖赏机制.这些研究深化了对网络成瘾心理和神经机制的理解,但仍存在网络成瘾筛查和入组标准不科学、分型笼统、因果研究匮乏、干预和治疗效果具有争议、研究范式存在漏洞等一些急需解决的问题.
Internet addiction（IA） as a behavioral addiction is currently becoming a serious mental health issue around the globe. According to the neurobiological model of brain development, exploring the neural mechanisms of reward seeking behavior and cognitive control in internet addicts may help in developing treatments for individuals with IA. Behavioral research has indicated that IA is commonly associated with enhanced reward sensitivity and decreased inhibitory control. Additionally, research focused on the neural mechanisms of IA indicates that deficits in the reward or cognitive control systems might be a high risk factor for addictive behaviors.Compared with substance addictions, IA, as a kind of psychological addiction, has a specific reward mechanism.While previous research has deepened the understanding of the psychological and neural mechanisms in IA, there still exist many issues surrounding diagnosis and treatment of IA： the screening criteria are not scientific; the classification is ambiguous; the effect of intervention and treatment is controversial; causal research is scarce; and research paradigms are flawed. Substantial future research is needed to explore, fully understand, and treat IA.
