Relevance theory and the study of linguistic interfaces in second language acquisition

Abstract

AbstractIn this paper we address Relevance-theoretical (RT) postulates with clear potential for contributing to the substantiation of the notion of interface in second language acquisition (SLA) processes. Whether the interface is considered the locus of contact between the structural linguistic properties and syntactic operations, on one hand, and the interpretive mechanisms of the conceptual-intentional system, on the other; or understood as points of interaction among cognitive modules, interfaces are fundamental to interpreting grammatical structures that require integrating discourse-contextual information. Assuming the RT conceptual-procedural meaning distinction is approximately correlated with that which exists between lexical and functional categories, it will be shown that recent research into SLA revolves around the problem of how procedural units are acquired. Certain functional categories, expressing interpretable features, have been analysed as encoding identical procedural indications across different languages. Thus, one challenge that L2 learners face is identifying diverse interface effects, derivable from a single procedure, across languages. To illustrate this point we discuss a recent analysis of phenomena involving tense and aspect acquisition applying RT principles to empirical findings. Finally, some new directions will be suggested for further theorizing in SLA research on inherent characteristics of utterance interpretation in an L2.
