Mechanisms for interaction: Syntax as procedures for online interactive meaning building: Commentary on Christiansen and Chater "The Now-or-Never Bottleneck: A Fundamental Constraint on Language"

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.
