Language as mechanisms for interaction

Abstract Language use is full of subsentential shifts of context, a phenomenon dramatically illustrated in conversation where non-sentential utterances displaying seamless shifts between speaker/hearer roles appear regularly. The hurdle this poses for standard assumptions is that every local linguistic dependency can be distributed across speakers, with the content of what they are saying and the significance of each conversational move emerging incrementally. Accordingly, we argue that the modelling of a psychologically-realistic grammar necessitates recasting the notion of natural language in terms of our ability for interaction with others and the environment, abandoning the competence-performance dichotomy as standardly envisaged. We sketch Dynamic Syntax, a model in which underspecification and incremental time-relative update is central, showing how interactive effects of conversation follow directly. Finally, we note the changing cognitive-science horizons to be explored once a language-as-action view is adopted.

Rethinking case marking and case alternation in Estonian

In this paper, we argue for a view of case marking that does not treat case as the passive realisation of other morpho-syntactic properties of a construction but as independently bringing information to a clause. This different view of case entails that precise functions of case-marked expressions may be determined by the interaction of the case marking, the meaning of the host noun, the semantics of any predicate of which it is an argument and other contextually given factors. With respect to Estonian, it is argued that there is only one ‘structural’ case, the genitive, and this case marks non-subject, or oblique, dependency on some head. The partitive case, we argue, is semantically partitive in all its uses, except that the partitive meaning can be obscured or even eliminated depending on contextual factors. The nominative is merely the absence of case, associated with no specific positions or semantic effects.

Mechanisms for interaction: Syntax as procedures for online interactive meaning building

We argue that to reflect participant interactivity in conversational dialogue, the Christiansen & Chater (C&C) perspective needs a formal grammar framework capturing word-by-word incrementality, as in Dynamic Syntax, in which syntax is the incremental building of semantic representations reflecting real-time parsing dynamics. We demonstrate that, with such formulation, syntactic, semantic, and morpho-syntactic dependencies are all analysable as grounded in their potential for interaction.
