The aim of this study was to explore associations between time spent using various media devices and executive abilities in preschoolers. Participants were 190 children (44.2% female; mean age 58.75 months, SD = 7.27). The Shape School, the Missing Scan and the Head and Feet tasks were administered to children to assess three core executive functions (mental set shifting, working memory, and inhibitory control). Parents provided information on the daily time children spent watching television and using smartphones, tablets, and computers. Parental education was also taken into consideration. Results of multiple linear regression analysis revealed that separate executive abilities were not predicted by use of any type of screen. To conclude, our findings suggest that screen time is not related to executive functions in typically developing low social risk preschoolers who are not overusing screens.

学龄前儿童的执行功能和基于屏幕的媒体使用

这项研究的目的是探索使用各种媒体设备所花费的时间与学龄前儿童的执行能力之间的联系。参与者为190名儿童（女性占44.2％；平均年龄58.75个月，SD）= 7.27）。对孩子们进行了Shape School，Missing Scan和Head and Feet任务，以评估三个核心执行功能（心理状态转移，工作记忆和抑制控制）。父母提供了有关孩子每天看电视和使用智能手机，平板电脑和计算机的时间信息。还考虑了父母教育。多元线性回归分析的结果表明，使用任何类型的屏幕都无法预测单独的执行能力。总而言之，我们的研究结果表明，筛选时间与通常发展为不过度使用筛选的低社会风险学龄前儿童的执行功能无关。
