Usage-Based Models Around and Inside BLC Theory: Commentary on Hulstijn (2024)

In his essay entitled “Predictions of Individual Differences in the Acquisition of Native and Non-Native Languages: An Update of BLC Theory”, Jan Hulstijn updates his theory of Basic Language Cognition (Hulstijn 2011, 2015). His central claim is that there is a fundamental difference between the Basic Language Cognition that is sufficient for dealing with oral language and the Extended Language Cognition required for handling reading and writing. In my invited commentary, I argue that used-based models of language provide a wider theoretical background that helps to ground Hulstijn’s theory. I illustrate what this means with reference to the Entrenchment-and-Conventionalization Model (Schmid 2020). Based on this model I discuss Hulstijn’s predictions regarding the extent of interindividual differences to be expected among L1-speakers and L-2 speakers.
