Although digital media usage is prevalent among middle school students, the safety of digital media-based learning activities for students at risk of digital media addiction is unknown. The goal of this study was to evaluate the differences in students' brain activity in relation to their risk of digital media addiction. The study was quasi-experimental, with a pre- to post-test control group design. The study participants included 83 middle school students who were engaged in digital learning. We measured their brainwaves to evaluate brain activity using a PolyG-I (LAXTHA Inc.). We found no statistically significant differences in the location of the attention index between the two groups before and after digital learning. However, there were statistically significant differences between the two groups in the P3, P4, and F4 locations of the relaxation index. These results indicate that students at risk of digital media addiction may experience learning difficulties. These results can be used to guide healthcare professionals in developing digital learning programs that are safe for students and to also verify the effects of these programs.
虽然数字媒体在中学生中很流行，但对于有数字媒体成瘾风险的学生来说，基于数字媒体的学习活动的安全性尚不清楚。本研究的目的是评估与数字媒体成瘾风险相关的学生大脑活动的差异。该研究为准实验性，采用前后测对照组设计。研究参与者包括 83 名参与数字学习的中学生。我们使用 PolyG-I（LAXTHA Inc.）测量了他们的脑电波，以评估大脑活动。我们发现数字学习前后两组注意力指数的位置没有统计学上的显著差异。然而，两组在放松指数的 P3、P4 和 F4 位置有统计学上的显著差异。这些结果表明，有数字媒体成瘾风险的学生可能会遇到学习困难。这些结果可用于指导医疗保健专业人员开发对学生安全的数字学习计划，并验证这些计划的效果。
