Two general classes of pronoun disambiguation processes are considered. In reading “Jack threw a snowball at Phil, but he missed,” both possible antecedents of “he” (“Jack” and “Phil”) may be accessed initially. Or, the actual antecedent alone may be accessed after sufficient semantic context is encoded. To evaluate these alternatives, a yes-no-probe recognition task was used to measure priming of the potential antecedents in sentence comprehension. Subjects read sentences similar to the example and were presented a test word immediately following each sentence. Response times for the actual antecedent (“Jack”) and nonantecedent (“Phil”) probes were obtained. Results indicated that the nonantecedent as well as the antecedent was activated (accessed) in pronoun disambiguation. This conclusion was not affected by the ordering of the antecedent and nonantecedent in the first clause.
