In this commentary, I suggest that it may be helpful to think about the formidable problem space that Westergaard's (2021) Linguistic Proximity Model seeks to address at the three levels of analysis that Marr (1982) famously proposed are needed to understand any complex cognitive system. I argue that at the computational level of analysis, where…

Grammar competition has been proposed as a model for second language (L2) acquisition. Variational Learning provides a framework within which to investigate the idea of grammar competition as the model requires a marriage of quantitative properties of the input with Universal Grammar. A diachronic variational model of grammar competition is…

How strongly a verb is associated with a construction plays a crucial role in the learning of argument structure constructions. We examined the effect of verb-construction association strength on second language (L2) constructional generalization by analysing L2 learners' production and comprehension of two complex constructions (i.e. ditransitive…
