Parsing strategies and discourse context

Two experiments investigated syntactic processing during comprehension of sentences presented either in isolation or in a discourse context. Comprehension of a range of different types of surface structurally ambiguous sentences was studied. To explain the interpretations generally given to the sentences processed in isolation, two parsing principles were proposed: Kimball's (1973) Right Association and Verb Dominance. When the ambiguous sentences were read in context, the interpretations computed were still determined by these structurally based principles, even when this meant that the meanings were at variance with the prior context. These results indicate that surface structure parsing of sentences proceeds in the same way whether sentences are processed alone or in context.This research was supported by a grant from the Australian Research Grants Scheme.
