7 Summary
</SectionTitle>
    <Paragraph position="0"> The inherent left-to-right incrementality and monotonicity of DS as a grammar formalism allows both parsing and generation processes to be not only incremental but closely coupled, sharing structures and context. This enables shared utterances, cross-speaker elliptical phenomena and alignment to be modelled straightforwardly. A prototype system has been implemented in Prolog which re ects the model given here, demonstrating shared utterances and alignment phenomena in simple dialogue sequences. The signi cance of this direct reection of psycholinguistic data is to buttress the DS claim that the strictly serial incrementality of processing is not merely essential to the modelling of natural-language parsing, but 15Most frameworks would have to re ect this via preferences de ned over syntactic rules or parallelisms with syntactic trees in context, both problematic.</Paragraph>
