与青少年早期认知分数较低有关的学龄前社会媒体使用率较低, Low social media use by preteens linked to lower cognitive scores in early adolescence, per JAMA study.

JAMA的一项新研究将青少年早期社交媒体使用率低与低读数和记忆测试分数挂钩。 A new study in JAMA links even low levels of social media use among preteens to lower reading and memory test scores in early adolescence. 研究人员通过分析ABCD研究中6 000多名儿童的数据,发现13岁前每天使用社交媒体约一小时的儿童在认知测试中得分比认知测试低1至2个百分点,而每天使用3个或3个以上小时的儿童得分比非用户低4至5个百分点。 Analyzing data from over 6,000 children in the ABCD Study, researchers found that those using social media for about an hour a day by age 13 scored 1 to 2 points lower on cognitive tests, while those using three or more hours daily scored up to 4 to 5 points lower than non-users. 其影响似乎依赖剂量,细微的差异可能表明长期学习差距。 The effect appears dose-dependent, with small differences potentially signaling long-term learning gaps. 虽然这项研究没有证明因果关系,但专家们说,它使人们更加担心数字习惯会如何影响注意力和学术成绩,特别是随着以后的青春期使用量增加。 While the study does not prove causation, experts say it adds to concerns about how digital habits may affect attention and academic performance, especially as use rises in later adolescence.
