Abstract

The present study investigates whether quantifier scope is computed incrementally during online sentence processing. We exploited the free word order in German to manipulate whether the verbal predicate preceded or followed the second quantifier in doubly quantified sentences that required the computation of inverse scope. A possessive pronoun in the first quantifier that had to be bound by the second quantifier was used to enforce scope inversion. We tested whether scope inversion causes difficulty and whether this difficulty emerges even at a point before comprehenders have encountered the main verb. We report three pretests and two reading time experiments. The first two pretests were offline tests that established (1) that the sentences exhibited the assumed scope preferences and (2) that variable binding forced scope inversion. The third pretest employed self-paced reading to show that interpreting a bound variable is not difficult per se and that difficulty in the critical construction must thus be due to inverting scope. Incremental processing of quantifier scope was investigated in a self-paced reading experiment. We observed difficulty right after the second quantifier, but only if it appeared after the main verb, that is, after the predication was complete. Further evidence for late scope inversion comes from an eyetracking experiment. Again, a scope inversion effect could only be observed at the end of the sentence. Taken together, our study demonstrates that in German inverse scope is only computed at the sentence boundary
