Media form an integral part of children's environments and represent, amongst other domains, altered sensorimotor experiences. Fine motor skills (FMS) represent a fundamental prerequisite for learning and cognition and initial work has begun to show links with screen media usage – although work is scarce and the directionality is uncertain. Therefore, using a cross-lagged-panel design with 2 waves 1 year apart, we examined longitudinal links between media usage and FMS in 141 preschool children. Results show a negative cross-lagged path from media usage to FMS, which was also statistically significant when only newer media were examined, after controlling for parental educational attainment, immigrant status, device ownership, age of first use, working memory, and vocabulary. The study contributes to our understanding of links between media usage and FMS development.

媒体是儿童环境不可分割的一部分，除其他领域外，还代表了改变的感觉运动体验。精细运动技能 (FMS) 是学习和认知的基本先决条件，初步工作已开始显示与屏幕媒体使用的联系——尽管工作稀缺且方向不确定。因此，我们使用相隔 1 年的 2 个波的交叉滞后面板设计，检查了 141 名学龄前儿童的媒体使用和 FMS 之间的纵向联系。结果显示，在控制父母教育程度、移民身份、设备所有权、首次使用年龄、工作记忆和词汇后，从媒体使用到 FMS 的负交叉滞后路径在仅检查较新媒体时也具有统计学意义。
