Media exposure, such as viewing fantastical content, can have negative, immediate, and long-term effects on children's executive function. A recent study showed that watching fantastical content on a tablet can impair children's inhibitory control and prefrontal activation during the performance of a task. However, the same effect was not observed when children played fantastical games on a tablet. We aimed to replicate and extend this research by examining whether the same effects are observed during a cognitive flexibility task. In this study, preschool children (N = 32, 15 girls, Mean age in months (SD) = 60.6 (10)) viewed or played fantastical content on a tablet and performed a Dimensional Change Card Sort (DCCS) task before or after the media exposure. We assessed children's behavioral performance and prefrontal activation, as measured by functional near-infrared spectroscopy (fNIRS), and found no behavioral or neural changes after exposure. Our analyses using the Bayes factor supported the null hypothesis that children's cognitive flexibility is unaffected by watching or playing fantastical content.
接触媒体，如观看奇幻内容，可能会对儿童的执行功能产生负面的即时和长期影响。最近的一项研究表明，在平板电脑上观看奇幻内容会损害儿童在执行任务时的抑制控制和前额叶激活。然而，当儿童在平板电脑上玩奇幻游戏时，并未观察到同样的效果。我们旨在通过研究在认知灵活性任务中是否也能观察到相同的效果来重复和扩展这项研究。在本研究中，学龄前儿童（N = 32，15名女孩，月龄平均（标准差）= 60.6（10））在平板电脑上观看或玩奇幻内容，并在接触媒体之前或之后进行维度变化卡片分类（DCCS）任务。我们评估了儿童的行为表现以及通过功能近红外光谱（fNIRS）测量的前额叶激活情况，发现接触后没有行为或神经方面的变化。我们使用贝叶斯因子进行的分析支持了零假设，即儿童的认知灵活性不受观看或玩奇幻内容的影响。
