Abstract：
Using a structured literature search and meta-regression procedures, this chapter reports a study that sought to determine whether the associations between coordinated attention and language are moderated by operationalizations of coordinated attention, study design, and other participant characteristics. Studies were located using database searches. This resulted in 46 reports or datasets, 464 effect sizes representing 1,482 participants. Meta-regression was used to answer research questions regarding potential moderators of the effects sizes of interest, which were Pearson\'s r values quantifying the association between coordinated attention and language assessments. In the final models, we observed that overall effect sizes were significantly above zero, suggesting robust effects across variables of interest. Age when coordinated attention was measured was a significant moderator, suggesting that the relations between coordinated attention and language was stronger when coordinated attention was measured at earlier ages. Interestingly, the longitudinal gap duration between coordinated attention measurement and language assessment was a significant moderator suggesting that the relation between coordinated attention and language was stronger when the longitudinal gap duration was longer. We conclude the meta-analysis by suggesting the phenomena of interest-dynamic coordinated visual attention between infant and caregiver-is robust across operationalizations and has predictive value for concurrent and future language abilities.
摘要：
使用结构化的文献检索和元回归程序，本章报告了一项研究，旨在确定协调注意力和语言之间的关联是否通过协调注意力的操作来调节，研究设计，以及其他参与者特征。使用数据库搜索进行研究。这导致了46个报告或数据集，代表1,482名参与者的464个效应大小。元回归用于回答有关感兴趣的效应大小的潜在调节者的研究问题，这是皮尔逊的r值，量化了协调注意力和语言评估之间的关联。在最终的模型中，我们观察到总体效应大小显著高于零，建议对感兴趣的变量产生稳健的影响。测量协调注意力的年龄是一个重要的调节因素，这表明，当在较早的年龄测量协调注意力时，协调注意力和语言之间的关系更强。有趣的是,协调注意力测量和语言评估之间的纵向间隙持续时间是一个重要的调节因素，这表明当纵向间隙持续时间较长时，协调注意力和语言之间的关系更强。我们通过提示婴儿和护理人员之间的兴趣动态协调视觉注意现象来总结荟萃分析，在整个操作过程中都是稳健的，并且对并发和未来的语言能力具有预测价值。
