中文摘要： ADHD者发展为网络成瘾的比率高达37%，值得关注，存在一些促使ADHD者网络成瘾的重要易感因素。其中特定认知加工缺陷和特异的动机风格是潜在机制。在研究一中通过CPT任务、点探测任务、stroop任务、stop任务和n-back任务对比探索ADHD伴随网络成瘾和不伴随网络成瘾者的持续性注意、注意偏向、反应抑制和工作记忆这些认知加工功能差异，以评估ADHD者网络成瘾的高危认知变量；在研究二中，通过刺激寻求和延迟满足任务探索障碍的动机风格特点，试图证明动机风格的失调也是部分ADHD容易网络成瘾的重要影响因素。在研究三中我们根据前面两个研究的结果，对ADHD亚类型进行精确区分，分为高危认知缺陷ADHD、非高危认知缺陷ADHD、动机失调ADHD，通过两年网络使用情况的追踪评估，以判别三组儿童网络使用状况及网络成瘾率和网络成瘾程度，进一步明确这些易感因素，以及评估认知缺陷和动机缺陷的贡献程度。

英文摘要： The ratio of ADHD comorbidity of internet addiction is as high as 37%, not accidentally, there are some important risk factors to promote ADHD to be internet addiction. Specific cognitive processing deficit and motivational style are worthy of attention. In Study 1, comparing CPT task, dot probe task, Stroop task, the stop-signal task and the n-back task are used to explore differences in cognitive processing function of ADHD comorbidity of internet addiction and not comorbidity of internet addiction, the cognitive processing function includes sustained attention, attentional bias, response inhibition and working memory. The aim of study 1 is to assess high-risk cognitive variables of internet addiction of ADHD; Study 2 explores characteristics of motivation style of the two disorders by sensation seeking task, and to prove motivation style disorders is also high risk factors of some ADHD individuals being easy to be internet addiction. In Study 3, according to the results of the previous two studies, this paper conducts precise distinction between the ADHD subtypes, divided into high-risk cognitive deficits in ADHD, non-high risk cognitive deficits in ADHD and motivational disorder in ADHD. Through two years of network usage tracking assessment, we distinguish three groups in condition of children network usage
