Abstract: This paper describes a computational cognitive model of human language processing under development in the ACT-R cognitive architecture.The paper begins with the context for the research, followed by a discussion of the primary theoretical and modeling commitments.The main theoretical commitment is to develop a language model which is at once functional and cognitively plausible.The paper continues with a description of the word recognition subcomponent of the language model which uses a perceptual span and ACT-R"s spreading activation mechanism to activate and select the lexical unit that most closely matches the perceptual input.Next we present a description of the linguistic structure building component of the model which combines parallel, probabilistic processing with serial, pseudodeterministic processing, including a non-monotonic context accommodation mechanism.A description of the mapping of linguistic representations into a situation model, follows.The paper concludes with a summary and conclusions.
