Recent work on the acquisition of number words has emphasized the importance of integrating linguistic and developmental perspectives [Musolino, J. (2004). The semantics and acquisition of number words: Integrating linguistic and developmental perspectives. "Cognition 93", 1-41; Papafragou, A., Musolino, J. (2003). Scalar implicatures: Scalar…

Presents a hybrid ACT-R model that shows U-shaped learning of the English past tense without direct feedback, changes in vocabulary, or unrealistically high rates of regular verbs. Illustrates that the model can learn the default rule, even if regular forms are infrequent. Shows that the model can explore the question of why there is a distinction…

Presents the goals of the Plunkett and Marchman (PM) connectionist model of the acquisition of verb morphology, and responds to related criticisms. Claims that small vocabulary size allows young children to correctly produce both regular and irregular past tense forms, and that non-linearities in vocabulary growth are a contributing factor to the…

Demonstrates that an understanding of children's language-acquisition difficulties with a wide range of syntactic constructions should be derived from limitations on the child's ability to deal with processing load and formal representational complexity. Maintains this can be done only in the context of a view of syntactic representation…

Used head-mounted eye-tracking system to study kindergartners' and adults' moment-by-moment language processing ability as they responded to spoken instructions. Found that 5-year-olds did not take into account relevant discourse/pragmatic principles when resolving temporary syntactic ambiguities and showed little/no ability to revise initial…
