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.
通过母亲的阅读能力和流畅度评估的早期语言接触和亲子共读，会影响孩子未来的语言和认知能力。本研究的目的是利用扩散张量成像（DTI）探索母亲的阅读能力和流畅度与其学龄前儿童语言和认知相关白质束的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）。对她们母亲的阅读能力和流畅度进行了评估。在与语言和认知能力相关的白质束上的100个点处测量了半球和节点对扩散特性的影响。发现母亲的阅读能力与左、右背侧和腹侧语言及执行功能相关束的分数各向异性之间存在显著正相关，而母亲的阅读流畅度与腹侧束（主要在左半球）中较高的分数各向异性相关。与右侧相比，左侧的弓状束、扣带束和下纵束的分数各向异性显著更高，与左侧相比，右侧的上纵束分数各向异性更高。我们的研究结果表明母亲阅读作为孩子未来语言和认知能力促进因素的重要性。
