Problematic smartphone use (PSU) is common among young people and linked to poor academic performance. However, how PSU affects learning processes remains unclear. This study investigated the influence of auditory cue stimulation during a reading task on the mental workload and prefrontal brain activity of young individuals with PSU. Sixteen university students with PSU and 14 healthy controls (HC) performed a silent reading task, during which fake notification sounds were introduced. Their mental workload was assessed using the NASA Task Load Index (NASA-TLX), and prefrontal brain activity was measured using functional near-infrared spectroscopy (fNIRS). The results of the NASA-TLX suggest that the PSU group experienced greater frustration than the HC group. The fNIRS results showed that in the right medial prefrontal region of the HC group, OHb levels increased following cue stimulation, whereas no change was observed in the PSU group. Moreover, in the HC group, HHb levels in the left lateral prefrontal region decreased after cue stimulation. The findings of the present study demonstrate that university students with PSU experience frustration and exhibit deactivation in the prefrontal regions associated with the executive control network during silent reading in realistic learning situations.
智能手机使用问题（PSU）在年轻人中很常见，并且与学业成绩不佳有关。然而，PSU 如何影响学习过程尚不清楚。本研究调查了在阅读任务期间听觉提示刺激对有 PSU 的年轻个体的精神工作负荷和前额叶脑活动的影响。16 名有 PSU 的大学生和 14 名健康对照组（HC）进行了无声阅读任务，在此期间引入了假通知声音。使用 NASA 任务负荷指数（NASA-TLX）评估他们的精神工作负荷，使用功能近红外光谱（fNIRS）测量前额叶脑活动。NASA-TLX 的结果表明，PSU 组比 HC 组经历了更大的挫折。fNIRS 的结果表明，在 HC 组的右内侧前额叶区域，在提示刺激后 OHb 水平增加，而 PSU 组没有观察到变化。此外，在 HC 组中，在提示刺激后左外侧前额叶区域的 HHb 水平下降。本研究的结果表明，在现实学习情境中的无声阅读中，大学生 PSU 组经历挫折，并且在与执行控制网络相关的前额叶区域表现出失活。
