In a questionnaire study the effects of discourse structural information on resolving inter-sentential anaphora were investigated. The Right Frontier Constraint, first proposed by Polanyi (1988), states that potential antecedents of an anaphor that are placed at the right frontier of a discourse unit can be accessed more easily than antecedents that are placed somewhere else. Participants (N=36) received written experimental passages of six lines each that contained a pronominal anaphor in the last line and two potential antecedents in the preceding text, one introduced in the first, one in the fourth line of a passage. Antecedents' relative position to the right frontier was manipulated through the discourse relation between the first and the second antecedent and through the filler information interposed between the second antecedent and the anaphor. The two potential antecedents either had the same or different grammatical gender. In the latter case only the first antecedent wa...
