Gigley Department of Computer Science University of New Hampshire Durham NH 03824 ABSTRACT How can grammar be viewed as a functional part of a cognitive system Given a neural basis for the processing control paradigm of language performance what roles does grammar play Is there evidence to suggest that grammatical processing can be Independent from other aspects of language processing This paper will focus on these issues and suggest answers within the context of one computational solution. The example model of sentence comprehension HOPE is intended to demonstrate both representational considerations for a grammar within such a system as well as to Illustrate that by interpreting a grammar as a feedback control mechanism of a neural-like process additional Insights into language processing can be obtained. 1. Introduction The role of grammar in defining cognitive models that are neurally plausible and psychologically valid will be the focus of this paper. While inguistic theory greatly influences the actual representation that is included in any such model there are vast differences in how any grammar selected is processed within a natural computation paradigm. The processing does not grow trees explicitly it does not transform trees explicitly nor does it move constituents. In this type of model a grammar is an explicit encoded representation that coordinates the integrated parallel process. It provides the Interfaces between parallel processes that can be interpreted within semantic and syntactic levels separately. It furthermore acts as a conductor of a time-synchronized process. Aspects of how a grammar might be processed within a cognitive view of sentence comprehension will be demonstrated within an Implemented model of such processing HOPE Gigley 1981 1982a 1982b 1983-1984 1985 . This view of grammatical process suggests that neural processing should be included as a basis for defining what
