6 Conclusions
</SectionTitle>
    <Paragraph position="0"> This is by far no complete account of the determinants of the production of passive sentences. Rather, the aim of the foregoing discussion was to sketch a computational model of natural language production that links psycholinguistically established aspects of linguistic performance with a competence model in the form of an HPSG-style declarative grammatical knowledge base.</Paragraph>
    <Paragraph position="1"> The crucial features of the process model are its incrementality and highly constrained modularity. Each sub-component of the overall process is governed by its own set of principles, with no feedback between components.</Paragraph>
    <Paragraph position="2"> We dealt with the relation between the pre-linguistic conceptualizing component and the linguistic formulation component in some detail in the present paper. The Concep01_~lizer's mode of operation is guided by general cognitive principles that, for example, select among the ingredients of a situation those considered to be apt for linguistic presentation and determine the order in which units of the content to be expressed are passed on to the linguistic component, in fact independent in principle of requirements specific to the latter. The Formulator has a number of language-system internal devices at its command to cope with the material delivered by the Conceptualizer. The discussion of the production of passives served to illustrate how the SYNPHONICS generation system models this situation.</Paragraph>
