Disambiguation preferences and corpus frequencies in noun phrase conjunction

Abstract

Gibson and Schütze (1999) showed that on-line disambiguation preferences do not always mirror corpus frequencies. When presented with a syntactic ambiguity involving the conjunction of a noun phrase to three possible attachment sites, participants were faster to read attachments to the first site than attachments to the second one, although the latter were shown to be more frequent in text corpora. In the present study, we investigated whether a particular feature in their items—disambiguation using the pronoun ‘one’—could account for this discrepancy. The results of a corpus analysis and two on-line reading experiments showed that the presence of this pronoun is indeed responsible for the high attachment preference in the conjunction ambiguity. We conclude that for this syntactic ambiguity there is no discrepancy between on-line preferences and corpus frequencies. Consequently, there is no need to assume different processes underlying sentence comprehension and sentence production on the basis of the noun phrase conjunction ambiguity.
