人们对指点手势的起源知之甚少。我们试图通过两种方式调查12个月大婴儿指点的个体差异，以期深入了解它的出现。首先，我们研究了指点的交流和互动用法的差异，并询问了不同的手形与指点频率、伴随发声和母亲指点的关系。第二，我们观察了点理解和模仿的社会认知技能的差异，并测试这些技能是否与婴儿自己的指向有关。婴儿和母亲的自发指向彼此相关，婴儿的指向产生和理解也是如此。特别是，婴儿食指指向的轮廓与简单的全手指向不同。它更频繁，更频繁地伴随发声，它与对指点的理解(特别是对被遮挡的指称)的理解更密切相关。我们得出结论，全手指法和食指指法在本质上是不同的，并认为食指指法首先体现了婴儿对交际意图的理解。(C)2011 Elsevier Inc.保留所有权利。
Little is known about the origins of the pointing gesture. We sought to gain insight into its emergence by investigating individual differences in the pointing of 12-month-old infants in two ways. First, we looked at differences in the communicative and interactional uses of pointing and asked how different hand shapes relate to point frequency, accompanying vocalizations, and mothers' pointing. Second, we looked at differences in social-cognitive skills of point comprehension and imitation and tested whether these were related to infants' own pointing. Infants' and mothers' spontaneous pointing correlated with one another, as did infants' point production and comprehension. In particular, infants' index-finger pointing had a profile different from simple whole-hand pointing. It was more frequent, it was more often accompanied by vocalizations, and it correlated more strongly with comprehension of pointing (especially to occluded referents). We conclude that whole-hand and index-finger pointing differ qualitatively and suggest that it is index-finger pointing that first embodies infants' understanding of communicative intentions.
