Early language exposure and shared parent-child reading, as assessed by maternal reading ability and fluency, affect the child's future language and cognitive abilities. The aim of the current study was to explore the association between maternal reading ability and fluency and diffusion properties of language- and cognition-related white matter tracts in their pre-school age children using diffusion tensor imaging (DTI). DTI data were acquired from fifteen girls (mean age: 3.83 ± 0.49 years). Reading ability and fluency were assessed in their mothers. Effects of hemisphere and node on diffusion properties were measured at 100 points along white matter tracts related to language and cognitive abilities. Significant positive correlations were found between maternal reading ability and fractional anisotropy in left and right dorsal and ventral language and executive functions-related tracts, while maternal reading fluency was associated with higher fractional anisotropy in ventral tracts, mainly in the left hemisphere. Fractional Anisotropy was significantly higher in the left compared to the right arcuate, cingulum cingulate, and inferior longitudinal fasciculus and higher in the right compared to the left superior longitudinal fasciculus. Our results signify the importance of maternal reading as a facilitator of the child's future language and cognitive abilities.

产妇的阅读和流利能力与其学龄前儿童腹侧和背侧白质束的扩散特性有关。

根据母亲的阅读能力和流利程度评估，早期语言接触和共享的亲子阅读会影响孩子未来的语言和认知能力。本研究的目的是使用扩散张量成像（DTI）探索母体阅读能力与学龄前儿童与语言和认知相关的白质束流利度和扩散特性之间的关联。DTI数据来自15名女孩（平均年龄：3.83±0.49岁）。他们的母亲对阅读能力和流利度进行了评估。在与语言和认知能力有关的白质束沿100个点测量了半球和结点对扩散特性的影响。左，右背和腹侧语言以及与执行功能相关的管道中，母亲的阅读能力与分数各向异性之间存在显着的正相关关系，而母亲的阅读流利度则与腹侧管道中较高的分数各向异性相关，主要在左半球。与右侧弓形，扣带扣带回和纵纵筋膜相比，左侧的分数各向异性明显较高，而与左侧纵纵筋膜相比，右侧的分数各向异性较高。我们的研究结果表明，母亲阅读对孩子未来语言和认知能力的促进作用非常重要。与右侧弓形，扣带扣带回和纵纵筋膜相比，左侧的分数各向异性明显较高，而与左侧纵纵筋膜相比，右侧的分数各向异性较高。我们的研究结果表明，母亲阅读对孩子未来语言和认知能力的促进作用非常重要。与右侧弓形，扣带扣带回和纵纵筋膜相比，左侧的分数各向异性明显较高，而与左侧纵纵筋膜相比，右侧的分数各向异性较高。我们的研究结果表明，母亲阅读对孩子未来语言和认知能力的促进作用至关重要。
