Technology is pervasive in homes of families with young children, despite evidence for negative associations between infant exposure to screen-based media and cognitive development that has led the American Academy of Pediatrics (AAP) to discourage parents from exposing children under the age of 18 months to any kind of screen time (AAP, 2016). Here, we apply a propensity score matching approach to estimate relations between electronic screen-based media use in infancy and executive function in early toddlerhood. In an international sample of 416 firstborn infants, parental report of regular exposure to screen-based media at 4 months predicted poorer performance on a test of inhibition at 14 months, but was unrelated to either cognitive flexibility or working memory at 14 months. Results of this study are therefore consistent with the view that early exposure to screen-based media adversely affects the development of executive function.
尽管有证据表明婴儿接触基于屏幕的媒体与认知发展之间存在负面关联，这导致美国儿科学会（AAP）劝阻家长不要让 18 个月以下的儿童接触任何形式的屏幕时间（AAP，2016），但有年幼子女的家庭中，科技产品已无处不在。在这里，我们应用倾向评分匹配方法来估计婴儿期使用电子屏幕媒体与幼儿早期执行功能之间的关系。在一个由 416 名第一胎婴儿组成的国际样本中，父母报告在 4 个月大时经常接触基于屏幕的媒体，这预示着在 14 个月大时的抑制测试中表现较差，但与 14 个月大时的认知灵活性或工作记忆无关。因此，这项研究的结果与早期接触基于屏幕的媒体会对执行功能的发展产生不利影响的观点一致。
