Many Western industrialized nations have high levels of ethnic diversity but to date there are very few studies which investigate prelinguistic and early language development in infants from ethnic minority backgrounds. This study tracked the development of infant communicative gestures from 10 to 12 months (n = 59) in three culturally distinct groups in the United Kingdom and measured their relationship, along with maternal utterance frequency and responsiveness, to vocabulary development at 12 and 18 months. No significant differences were found in infant gesture development and maternal responsiveness across the groups, but relationships were identified between gesture, maternal responsiveness, and vocabulary development.
许多西方工业化国家具有高度的种族多样性，但迄今为止，很少有研究调查少数民族背景的婴儿的前语言和早期语言发展。本研究跟踪了英国三个文化背景迥异的群体中婴儿交际手势从 10 到 12 个月（n=59）的发展情况，并测量了他们与 12 个月和 18 个月词汇发展的关系，以及与母亲话语频率和反应的关系。研究小组发现，在婴儿手势发展和母亲反应方面，各组之间没有显著差异，但在手势、母亲反应和词汇发展之间存在关系。
