How early do children produce multiword utterances? Do children's early utterances reflect abstract syntactic knowledge or are they the result of data-driven learning? We examine this issue through corpus analysis, computational modeling, and adult simulation experiments. Chapter 1 investigates when children start producing multiword utterances; we use corpora to establish the development of multiword utterances and a probabilistic computational model to account for the quantitative change of early multiword utterances. We find that multiword utterances of different lengths appear early in acquisition and increase together, and the length growth pattern can be viewed as a probabilistic and dynamic process.

Speakers commonly re-purpose existing forms in the mental lexicon to create novel form-meaning. Contemporary evidence that such innovation processes have occurred historically is attested in varying degrees of polysemy in the mental lexicon. This dissertation considers speaker motivations underlying these innnovation processes historically. Strong synchronic relationships between frequency and degree of polysemy, on one hand, and frequency and lexical access, on the other hand, have traditionally been interpreted as evidence for the primacy of economic motivations in processes of lexical innovation. In contrast, the cognitive processes that most commonly facilitate innovation, metaphor and metonymy, have largely been described as processes …
