Screen time at ages 1 and 6 may matter more than parents realize

A longitudinal study of 502 children found that heavier screen viewing at ages 1 and 6 was associated with poorer academic performance and weaker working memory later in childhood. The findings suggest that both the amount and timing of screen exposure may matter.

一项针对502名儿童的纵向研究发现，孩子在1岁和6岁时观看屏幕时间较长，与其日后学业表现较差和工作记忆较弱有关。研究结果表明，屏幕接触的时长和发生阶段都可能很重要。
