摘要

网络成瘾作为一种行为成瘾，目前已成为全球范围内严重的心理健康问题。根据大脑发育的神经生物学模型，探索网络成瘾者的奖励寻求行为和认知控制的神经机制可能有助于开发IA个体的治疗方法。行为学研究表明，IA通常与奖励敏感性增强和抑制控制下降有关。此外，对IA神经机制的研究表明，奖励或认知控制系统的缺陷可能是成瘾行为的高风险因素。与物质成瘾相比，IA作为一种心理成瘾，具有特定的奖励机制。虽然以往的研究加深了对IA的心理和神经机制的认识，但围绕IA的诊断和治疗仍存在许多问题:筛查标准不科学;分类是模糊的;干预和治疗的效果存在争议;因果研究很少;研究范式是有缺陷的。未来需要大量的研究来探索、充分理解和治疗IA。

Neural Mechanisms of Reward Seeking Behavior and Cognitive Control in Individuals With Internet Addiction

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.

期刊介绍： Progress in Biochemistry and Biophysics is a monthly, peer-reviewed journal sponsored by Institute of Biophysics, The Chinese Academy of Sciences together with Biophysical Society of China. It started publication in 1974. It mainly reports on the latest developments in biochemistry, biophysics, molecular biology and neuroscience both in China and abroad. It contains several columns such as "reviews and monographs", "rapid and short communications", "research papers", "techniques and methods" and "academic discussions".
