The interpretative options of anaphoric complex demonstratives

In this paper, we present experimental evidence from a ‘yes’/’no’ judgement task and twoacceptability rating studies (Experiments 1a-c) for the claim made in Hinterwimmer (2019) thatsentences with two anaphorically interpreted complex demonstratives are less acceptable thansentences with two anaphorically interpreted definite descriptions and sentences where one ofthe two previously introduced referents is picked up by a complex demonstrative, while the otherone is picked up by a definite description. The results of Experiment 1a and 1b are in principlecompatible with the account argued for in Hinterwimmer (2019), according to which the (potentiallyabstract) demonstrations presupposed by demonstratives may not have overlapping trajectories.However, sentences with two anaphorically interpreted complex demonstratives are not judgedas unacceptable as would be expected if they involved a presupposition violation. Therefore, wepropose an alternative, economy-based pragmatic account that builds on Ahn (2019) and Nowak(2019). The question of whether the observed pattern is more compatible with the accountproposed by Hinterwimmer (2019) or the alternative pragmatic account is directly addressed in afurther acceptability rating study (Experiment 1c). The design of that study is similar to that ofExperiment 1b, but it includes as fillers both sentences clearly violating a presupposition andsentences violating a pragmatic constraint. Since the ratings for sentences containing twoanaphorically interpreted complex demonstratives are closer to the ratings for sentences violatinga pragmatic constraint than for sentences violating a presupposition, we conclude that thealternative pragmatic account is preferable to the account by Hinterwimmer (2019).
