An important theory of attention suggests that there are three separate networks that execute discrete cognitive functions: alerting, orienting and conflict networks. Recent studies showed that there was a dysfunction of attention in Internet Addiction. In order to investigate the underlying mechanism of attention dysfunction in Internet Addiction, we recorded performance related to the Attentional Network Test (ANT) in youth.
The ANT, a behavioral assay of the functional integrity of attention networks, was used to examine the performance in Internet Addiction and healthy controls.
Performance on the ANT clearly differentiated the participants with and without Internet Addiction in terms of mean reaction times (RTs). Compared with control group, the Internet Addiction group detected targets more slowly and this effect was evident only for spatial cue condition. The Internet Addiction group demonstrated deficits in the orienting network in terms of slower RT. There was no demonstration of a deficit in both the alerting and conflict network in Internet Addiction on this task.
The youth with Internet Addiction demonstrated deficits in the orienting network but normal functioning of the alerting and conflict attention networks.
注意的一个重要理论认为，存在三个独立的网络来执行离散的认知功能：警觉、定向和冲突网络。最近的研究表明，网络成瘾者存在注意力功能障碍。为了探究网络成瘾者注意力功能障碍的潜在机制，我们对青少年进行了与注意网络测试（ANT）相关的表现记录。
ANT 是注意力网络功能完整性的行为测定，用于检测网络成瘾者和健康对照组的表现。
根据平均反应时间（RT），ANT 明显区分了有和没有网络成瘾的参与者。与对照组相比，网络成瘾组检测到目标的速度更慢，这种影响仅在空间线索条件下明显。网络成瘾组在定向网络方面表现出 RT 较慢的缺陷。在这个任务中，网络成瘾者并没有表现出警觉和冲突网络的缺陷。
有网络成瘾的青少年在定向网络方面表现出缺陷，但警觉和冲突注意网络的功能正常。
