Infants' ability to form new object categories based on either visual or naming information alone was evaluated at two different ages (16 and 20 months) using an object manipulation task. Estimates of productive vocabulary size were also collected. Infants at both ages showed evidence of using visual information to categorize the objects, while only the older ones used naming information. Moreover, there was a correlation between vocabulary size and name-based categorization among the 20-month-olds. The present results establish that infants as young as 20 months can use the non-obvious cue of naming to categorize objects. The possibility of a link between this ability and lexical development is discussed.
通过一项物体操作任务，在两个不同年龄阶段（16个月和20个月）评估了婴儿仅基于视觉或命名信息形成新物体类别的能力。同时还收集了产出性词汇量的估计数据。两个年龄段的婴儿都表现出利用视觉信息对物体进行分类的迹象，而只有年龄较大的婴儿使用命名信息。此外，在20个月大的婴儿中，词汇量与基于命名的分类之间存在相关性。目前的研究结果表明，年仅20个月的婴儿就可以利用非明显的命名线索对物体进行分类。本文还讨论了这种能力与词汇发展之间存在联系的可能性。
