芬兰于韦斯屈莱大学的研究人员进行了一项长期追踪研究，结果挑战了人们对屏幕时间的常见认知1。该研究对260名儿童进行了8年的追踪，其中包括124名女孩和136名男孩，平均年龄15.8岁1。研究发现，儿童时期屏幕使用时间较多的孩子在青少年时期表现出更好的认知处理能力1。这一结论发表在《儿童运动科学》（Pediatric Exercise Science）2026年第38卷第3期上1。
研究还揭示了屏幕活动类型与身体活动强度的性别差异。在女孩中，低强度身体活动与更好的工作记忆相关；在男孩中，引导性身体活动与更好的工作记忆相关1。研究团队代表Petri Jalanko表示："我们不应仅将屏幕时间视为有害，而应寻求身体活动与促进主动思维的屏幕时间之间的平衡"1。这一研究强调，关键在于屏幕活动的类型，而不是笼统地反对屏幕使用1。
Finnish researchers conducted an eight-year longitudinal study tracking 260 children, including 124 girls and 136 boys with an average age of 15.8 years at the study's conclusion, and found that greater screen time during childhood was associated with improved cognitive processing abilities in adolescence.1 This finding contradicts the widespread assumption that screen time is inherently harmful to development. The research was published in Pediatric Exercise Science in 2026, volume 38, issue 3, by scientists at the University of Jyväskylä.1
The study revealed important distinctions based on both screen activity type and gender. Among girls, low-intensity physical activity correlated with better working memory, while among boys, structured physical activity was linked to superior working memory performance.1 Researchers emphasized that the quality and nature of screen engagement matters significantly. Petri Jalanko, one of the study's researchers, stated: "We should not view screen time solely as harmful, but rather seek balance between physical activity and screen time that promotes active thinking."1
