Understanding Anaphora: Rules Used by Readers in Assigning Pronominal Referents

摘要

The focus of this experiment was on the analysis of cohesive elements within a text and on the difficulty of their resolution within a particular text structure. The cohesive form we selected was a particular type of anaphoric reference -- pronominal reference. The subjects' task was to read a text sentence by sentence. The texts presented contained pronouns, and referents for the pronouns. In addition to reading the text, subjects were occasionally asked to report the correct referent for a pronoun that had appeared in the sentence they have just completed. With this probe task motivating them to analyze carefully reference problems as they were encountered, subjects' reading times were found to be closely related to structural properties of the text. Text variables of importance included the number of potential referents available , topicalization of the correct referent, staging of references to the correct or to alternative noun phrases, and the degree of ambiguity of the semantic constraints within the target sentence used in selecting the proper referent.
