Familiar Words Can Serve As A Semantic Seed For Syntactic Bootstrapping

Young children can exploit the syntactic context of a novel word to narrow down its probable meaning. But how do they learn which contexts are linked to which semantic features in the first place? We investigate if 3- to 4-year-old children (n = 60) can learn about a syntactic context from tracking its use with only a few familiar words. After watching a 5-min training video in which a novel function word (i.e., 'ko') replaced either personal pronouns or articles, children were able to infer semantic properties for novel words co-occurring with the newly learned function word (i.e., objects vs. actions). These findings implicate a mechanism by which a distributional analysis, associated with a small vocabulary of known words, could be sufficient to identify some properties associated with specific syntactic contexts.
