Grammatical mapping in L3 acquisition
In this chapter, we focus on the question of how development may take place in multilingual and the role of prior knowledge in this process. The theoretical called (GM) (Lust, 2012 for L1 acquisition) supposes an active, albeit unconscious, creative involvement of the learner in the construction of the constrained and guided by (UG). We propose that the GM paradigm provides a valid and principled account of the process of multilingual acquisition as well. By means of presenting concrete examples from our previous experimental research, we will illustrate how the three essential predictions deriving from this paradigm also bear out in the multilingual scenario. Similar to L1 acquisition, UG’s and invariant principle(s) are shown to be at work in . Moreover, based on of multilingual learners’ in elicited productions, we present tangible indications that multilingual learners draw upon previously known language grammars while engaged in linguistic computation – analysis, dissociation and integration – of target language-specific components. Our contribution to the is the specification of the manner in which multilingual learners draw upon previous knowledge in the construction of new target grammar, thus extricating explicit from implicit linguistic knowledge. We expect that the application of this paradigm onto multilingual experimental data may shed light on the degree to which domain-specific innate principles guide and constrain language acquisition in general.
