Abstract

According to recent research, the level of problematic Internet use (PIU) is associated with chronic mental fatigue. In contrast to chronic fatigue, the association between PIU and task-induced fatigue has not been investigated. Based on previous scientific work, it is conceivable that task-induced subjective fatigue and PIU may share a common neurological background. Therefore, investigation of the association between them is indispensable. We used the Psychomotor Vigilance Task to induce fatigue and functional magnetic resonance imaging (fMRI) to investigate changes in the blood-oxygen-level-dependent (BOLD) signal during the task, and a self-reported questionnaire to assess PIU. We found that the extent of PIU predicted subjective mental fatigue changes during the task. Task-induced changes in the BOLD signal in the left precuneus, and in the left medial, middle, and superior frontal gyri correlated negatively with the PIU level. In addition, task- and PIU-related changes in the BOLD signal within these areas were negatively associated with the changes in subjective mental fatigue. Our findings highlight the association between PIU and task-induced subjective mental fatigue.

在有问题的互联网使用中增加任务诱发的精神疲劳：一项功能磁共振成像研究

根据最近的研究，有问题的互联网使用（PIU）的水平与慢性精神疲劳有关。与慢性疲劳相反，PIU与任务诱发疲劳之间的关系尚未得到研究。基于以往的科学工作，可以想象任务诱发的主观疲劳和PIU可能具有共同的神经学背景。因此，研究它们之间的关联是必不可少的。我们使用精神运动警觉性任务诱导疲劳和功能性磁共振成像（fMRI）来研究任务期间血氧水平依赖（BOLD）信号的变化，并使用自我报告的问卷来评估PIU。我们发现PIU的程度可以预测任务过程中主观心理疲劳的变化。任务诱导的左楔前叶、左内侧、中、额上回BOLD信号的变化与PIU水平呈负相关。此外，这些区域内BOLD信号的任务和piu相关变化与主观精神疲劳的变化呈负相关。我们的研究结果强调了PIU与任务诱发的主观精神疲劳之间的联系。
