Verbal labels have been shown to help preverbal infants’ performance on various cognitive tasks, such as categorization. Redundant labels also aid adults’ visual working memory (WM), but it is not known if this linguistic benefit extends to preverbal infants’ WM. In two eye-tracking studies, we tested whether 8- and 10-month-old infants’ WM performance would improve with the presence of redundant labels in a Delayed Match Retrieval (DMR) paradigm that tested infants’ WM for object-location bindings. Findings demonstrated that infants at both ages were unable to remember two object-location bindings when co-presented with labels at encoding. Moreover, infants who encoded the object-location bindings with labels were not significantly better than those who did so in silence. These findings are discussed in the context of label advantages in cognition and auditory dominance.

语言标签已被证明可以帮助未使用语言的婴儿在各种认知任务（例如分类）上的表现。冗余标签也有助于成人的视觉工作记忆 (WM)，但尚不清楚这种语言优势是否会扩展到会说话的婴儿的 WM。在两项眼动追踪研究中，我们测试了 8 个月和 10 个月大婴儿的 WM 表现是否会因延迟匹配检索 (DMR) 范式中冗余标签的存在而提高，该范式测试了婴儿 WM 的对象位置绑定。研究结果表明，当在编码时与标签共同呈现时，两个年龄段的婴儿都无法记住两个对象位置绑定。此外，用标签对对象位置绑定进行编码的婴儿并不比那些默默地这样做的婴儿好得多。
