    "title": "Modeling Children’s Early Linguistic Productivity Through the Automatic\nDiscovery and Use of Lexically-based Frames",
    "subtitle": null,
    "abstract": "A central question for cognitive science is whether children’s\nlinguistic productivity can be captured by item-based\nlearning, or whether the learner must be guided by abstract,\nsystem-wide principles governed by innate constraints. Here,\nwe present a computational model of early language\nacquisition which learns to discover and use lexically-based\nframes in a fully incremental, on-line fashion. The model is\nrooted in simple prediction- and recognition-based processes,\nsubject to the same memory limitations as language learners.\nWhen exposed to English corpora of child-directed speech,\nthe model is able learn developmentally plausible frames and\nuse them to capture over 70% of the utterances produced by\ntarget children aged 2 to 5. Across a typologically diverse\nrange of 29 languages, the model is able to capture over 68%\nof child utterances. Together, these findings suggest that\nmuch of children’s early linguistic productivity can be\ncaptured by item-based learning through computationally\nsimple mechanisms.",
