The aim of this study was to investigate the relationship between hand preference for communicative gestures and language during development. Hand preference for pointing gestures and level of language were assessed in 46 toddlers between 12 and 30 months of age. Results showed a right-hand preference for pointing and the use of a developmental quotient (DQ) for language revealed a significant correlation between the degree of hand preference and DQ for language in children with a quotient above 100. Thus, these children were more right-handed for pointing gestures as DQ increased. These results highlight the close association between the development of hand preference for pointing and the speed of language development, suggesting a new direction for studies of language-gesture links in toddlers.
本研究旨在探讨发展过程中手势交际偏好与语言之间的关系。我们评估了 46 名 12 至 30 个月大的幼儿的手势指向偏好和语言水平。结果显示，幼儿在指向手势方面存在右利手偏好，语言发展商数（DQ）显示，在 DQ 高于 100 的儿童中，手偏好程度与语言 DQ 之间存在显著相关性。因此，随着 DQ 的增加，这些儿童在指向手势方面更加惯用右手。这些结果强调了手势指向偏好发展与语言发展速度之间的密切联系，为幼儿语言手势关联的研究提供了新的方向。
