Language is a signature of our species and our primary conduit for conveying the contents of our minds. The power of language derives not only from the exquisite detail of the signal itself but also from its intricate link to human cognition. To acquire a language, infants must build a link between linguistic and conceptual information, mapping specific words to the concepts those words represent. Previous research has examined how older children construct this mapping, showing that labelling a series of category exemplars with the same noun facilitates the formation of the object category (e.g., Plunkett, Hu, and Cohen, 2008). In a series of studies, I map out how this link between language and categorization emerges and becomes more precise during the first year of life. Infants between the ages of 3 and 12 months participated in an object categorization task, with a variety of sounds paired to each exemplar. The results showed that throughout development, infants become increasingly refined in the sounds that facilitate categorization; while a specific range of sounds can facilitate categorization early in development, the process becomes increasingly specific to consistent labels by the end of the first year. These findings suggest a path of specialization that supports infants as they forge the foundational links between human language and the core cognitive processes that will serve as the foundations of meaning.
