Nick Ellis and Dave Ogden have published a commentary in the March 2015 issue of the Journal of Child Language (full citation below). In response to a review article by Ben Ambridge, Evan Kidd, Caroline Rowland, and Anna Theakston, Ellis and Ogden applaud those researchers' summary of evidence for frequency effects in language acquisition. They go on argue for the value of research that seeks domain-general cognitive accounts of language acquisition, and provide an overview of other cognitive drivers of learning, including recency, context, and contingency. They advocate using ever-advancing corpus, statistical, and computational modeling tools to explore these learning mechanisms.
