The German causal preposition durch ('by', 'through') poses a challenge to formal-semantic analyses applying strict compositionality. To deal with this challenge, a formalism which builds on recent important developments in Discourse Representation Theory is developed, including a more elaborate analysis of presuppositional phenomena as well as the integration into the theory of unification as a mode of composition. It is argued that that the observed unificational phenomena belong in the realm of pragmatics, providing an argument for presuppositional phenomena at a sentence- and word-internal level.
This paper presents two experimental studies investigating the processing of presupposed content. Both studies employ the German additive particle auch (too). In the first study, participants were given a questionnaire containing bi-clausal, ambiguous sentences with 'auch' in the second clause. The presupposition introduced by auch was only satisfied on one of the two readings of the sentence, and this reading 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. The second study 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. It is argued that the two 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 semantic theory and dynamic accounts of presuppositions as well as for theories of semantic processing are discussed.
This study examines articulatory and acoustic inter-speaker variability in the production of the German vowels /i/, /u/ and /a/. Our subjects are 3 monozygotic twin pairs (2 female and 1 male pair) and 2 dizygotic female twin pairs. All of them were born, raised and are still living in Berlin and see their twin brother or sister regularly. We assume that monozygotic twins that are genetically identical and share the same physiology should be more similar in their articulation than dizygotic twins but that the shared time and social environment of twins, regardless of their genetic similarity, also plays a crucial role in the acoustic similarity of twins. Articulatory measurements were made with EMA (Electromagnetic Articulography) and the target positions of the produced vowels were analyzed. Additionally, the formants F1-F4 of each vowel were measured and compared within the twin pairs. Our data seems to point out the importance of a shared environment and the strong influence of learning over the anatomical identity of the monozygotic twins regarding the production of vowels. But, additional results suggest (1) the impact of physiology on the production of a vowel following a velar consonant and (2) the interaction of physiology and stress in inter-speaker variability.
