This paper presents three experimental studies investigating the processing of presupposed content. The first two experiments employ the German additive particle auch too, and the third uses English also. In experiment 1, participants were given a questionnaire containing biclausal, ambiguous sentences containing auch. The presupposition introduced by auch was only satisfied on one of the two readings, which corresponded to a syntactically dispreferred parse of the sentence. The prospect of having the auch presupposition satisfied made participants choose this syntactically dispreferred reading more frequently than in a control condition. Experiment 2 used the self-paced reading paradigm and compared the reading times on clauses containing auch, which differed in whether the presupposition of auch was satisfied or not. Participants read the clause more slowly when the presupposition was not satisfied. Experiment 3 followed up a number of issues that arose from experiment 2 and confirmed the results found there. These studies show that presuppositions play an important role in online sentence comprehension and affect the choice of syntactic analysis. Some theoretical implications of these findings for the semantic analysis of auch/also and dynamic accounts of presuppositions as well as for theories of semantic processing are discussed.
