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.

It is well established that language production and comprehension are influenced by information status, for example, whether information is given, new, topical, or predictable, and many scholars suggest that an important component of information status is keeping track of what information is in common ground, and what is not. Information status affects both speakers' choices and how listeners interpret the speaker's meaning. Although there is a wealth of scholarly work on information status, there is no consensus on the mechanisms by (...) which it is used, and in fact relatively little discussion of the underlying representations and psycholinguistic mechanisms. Moreover, a major challenge to understanding information status is that its effects are notoriously variable. This study considers existing proposals about information status, focusing on two questions: how is it represented; and by what mechanisms is it used? I propose that it is important to consider whether representations and mechanisms can be classified as either explicit or emergent. Based on a review of existing evidence, I argue that information status representations are most likely emergent, but the mechanisms by which they are used are both explicit and emergent. This review provides one of the first considerations of information status processing across multiple domains. (shrink)
