Co-activation in bilingual grammars: A Gradient Symbolic Computation account of code mixing
In this presentation we outline a novel approach to code-mixing that combines aspects of formal linguistic theory and the wealth of psycholinguistic evidence that suggest that bilinguals simultaneously co-activate elements from both source languages during production (e.g., see Kroll & Gollan 2014, for a review). We propose to integrate these two traditions within the formalism of Gradient Symbolic Computation (Smolensky et al. 2014; Goldrick et al. forthcoming). This approach allows us to formalize the integration of grammatical principles with gradient mental representations. We apply this framework to code-mixing structures: in particular, portmanteaus, where an element is doubled, appearing in both languages within a single utterance. While one might classify such portmanteaus as a production error, these utterances are evidence that the second source grammar has not completely been inhibited once the matrix language has been selected. Through GSC we discuss the conditions under which these doubled-structures can be realized.
