Response to Open Peer Commentaries of Hulstijn’s (2024) Update of BLC Theory

Abstract

In this article, I respond to six peer commentaries of my essay in Languages 2024, containing an update of BLC Theory. I address the following issues: embedding BLC Theory in more than one metatheory; the match between the theory and usage-based models; the importance of processing pressures; the distinction between BLC and ELC; the study of heritage languages; the roles of cognitive factors in L1 and L2 attainment
