The Slithy Toves Did Gyre And Gimble: How Toddlers Use Linguistic Information to Learn New Words Sudha Arunachalam Speech, Language & Hearing Sciences Boston University To learn the meaning of a word, children must coordinate information from different sources, e.g., their visual observation of the world, and the linguistic context in which the word appears. This may be particularly challenging for verbs, because (a) observational contexts often present multiple possible interpretations for a new verb, and (b) verbs are often uttered in the absence of their observable referents. I will present several word learning experiments exploring 2-year-olds' use of linguistic information to meet these challenges. The results highlight the tandem development of the child's linguistic and other cognitive processing abilities, as well as their abilities to integrate information from different sources over time.
