Given that my paper touched upon many aspects of L1 an L2 acquisition, it is not surprising that the commentaries have raised a diverse range of issues. Nevertheless, one should not lose sight of the fact that the paper has a tightly defined focus, namely to delineate the influence of language processing factors and developmental dynamics on developmental trajectories in L1 and L2 acquisition, and this is done in a very explicit manner. As Carroll rightly puts it in her commentary, this “[e]xplicitness allows us to formulate questions which could otherwise not be asked.”
