Although the media can have both negative and positive effects on children's cognitive and motor functions, its influence on their perceptual bias and manual dexterity is unclear. Thus, we investigated the association between media viewing time, media preference level, perceptual bias, and manual dexterity in 100 school-aged children. Questionnaires completed by children and their parents were used to ascertain media viewing time and preference levels. Perceptual bias and manual dexterity were measured using the visual-tactile temporal order judgment task and Movement Assessment Battery for Children-2nd edition, respectively. There were significant positive correlations between age and media viewing time and between media viewing time and media preference level. There was also a significant negative correlation between visual bias and manual dexterity. Hierarchical multiple regression analysis revealed that increasing visual bias was a significant predictor of decreasing manual dexterity. Further, children with low manual dexterity showed significant visual bias compared to those with high manual dexterity, when matched for age and gender. The present results demonstrated that, in school-aged children, although viewing media was not associated with perceptual bias and manual dexterity, there was a significant association between perceptual bias and manual dexterity.
尽管媒体对儿童的认知和运动功能可能产生消极和积极影响，但其对儿童感知偏差和手部灵活性的影响尚不清楚。因此，我们调查了100名学龄儿童的媒体观看时间、媒体偏好程度、感知偏差和手部灵活性之间的关联。通过儿童及其父母填写的问卷来确定媒体观看时间和偏好程度。分别使用视觉-触觉时间顺序判断任务和儿童运动评估量表第二版来测量感知偏差和手部灵活性。年龄与媒体观看时间之间、媒体观看时间与媒体偏好程度之间存在显著的正相关。视觉偏差与手部灵活性之间也存在显著的负相关。分层多元回归分析显示，视觉偏差增加是手部灵活性下降的显著预测因素。此外，在年龄和性别匹配的情况下，手部灵活性低的儿童与手部灵活性高的儿童相比，表现出显著的视觉偏差。目前的结果表明，在学龄儿童中，尽管观看媒体与感知偏差和手部灵活性无关，但感知偏差和手部灵活性之间存在显著关联。
