"Race-Based Syntactic Attachment"
Abstract. We propose a processing model that tries to give a reasonable
account of how one might integrate several important psychological claims
about the human sentence parsing mechanism (namely that processing is in-
fluenced by limitations on working memory, a number of structural prefer-
ences, and parallelism of syntactic and semantic processing.) The starting
point for this proposal is the Sausage Machine model (Frazier and Fodor,
1978; Fodor and Frazier, 1980), which gives a good account of memory con-
straints and sentence complexity, and incorporates most of the structural
preferences we seek to include. We extend the original model by incor-
porating a principled theory of grammar, namely Government-Binding theory,
including mechanisms to handle lexical disambiguation and semantic process-
ing in parallel with syntactic processing, and using estimated timing in-
formation to resolve conflicting preferences.
