This paper describes a computational model of human sentence processing based on the principles and parameters paradigm of current linguistic theory. The syntactic processing model posits four modules, recovering phrase structure, long-distance dependencies, coreference, and thematic structure. These four modules are implemented as recta-interpreters over their relevant components of the grammar, permitting variation in the deductive strategies employed by each module. | Multiple Interpreters in a Principle-Based Model of Sentence Processing Matthew w.

The syntactic processing model posits four modules recovering phrase structure long-distance dependencies coreference and thematic structure. These four modules are implemented as meta-interpreters over their relevant components of the grammar permitting variation in the deductive strategies employed by each module. These four interpreters are also coroutined via the freeze directive of constraint logic programming to achieve incremental interpretation across the modules. 1 Introduction A central aim of computational psycholinguistics is the development of models of human sentence processing which account not only for empirical performance phe-nomena but which also provide some insight into the nature of between parser and grammar relationship. In concurrent research we are developing a model of sentence processing which has its roots in the principles and parameters paradigm of syntactic theory 1 2 which holds that a number of representations are involved in determining a well-formed analysis of an utterance. This in conjunction with Fodor s Modularity Hypothesis 6 has led US to postulate a model which consists of four informationally encapsulated modules for recovering 1 phrase structure 2 chains 3 coreference and 4 thematic structure. In this paper we will briefly review a model of sentence processing which has been previously proposed in 5 and 3 . We will illustrate how this model can be naturally implemented within the logic programming paradigm. In particular we sketch a subset
