In this paper we report the results of an elicited imitation task on dative case marking in non-canonical double object constructions with 22 German children (3;9-6;8). The aim was to test the proficiency of the children's grammar and to see which strategies they use to produce ditransitive sentences in which the direct object precedes the indirect object. The analysis of the children's utterances/imitations shows that the animacy of the direct object affects the overt dative case marking of the indirect object. Children made more errors repeating dative case marking when the direct object was inanimate, i.e., they produced the accusative case on the indirect object (non-adult-like). When both objects were animate, children correctly produced the dative case on the indirect object. We describe and account for these performance strategies of the children in the framework of Optimality Theory. Assuming that the same universal constraints are at work as in the adult grammar, the difference between adults and children lies in the constraint ranking. We focus on a prominent pattern found in children's performance, which is absent (or rather oppressed) in the corresponding adult performance, and show that one and the same grammar accounts for both (in the sense of "strong continuity").

We present a general framework for integrating annotations from different tools and tag sets. When annotating corpora at multiple linguistic levels, annotators may use different expert tools for different phenomena or types of annotation. These tools employ different data models and accompanying approaches to visualization, and they produce different output formats. For the purposes of uniformly processing these outputs, we developed a pivot format called PAULA, along with converters to and from tool formats. Different annotations are not only integrated at the level of data format, but are also joined on the level of conceptual representation. For this purpose, we introduce OLiA, an ontology of linguistic annotations that mediates between alternative tag sets that cover the same class of linguistic phenomena. All components are integrated in the linguistic information system ANNIS : Annotation tool output is converted to the pivot format PAULA and read into a database where the data can be visualized, queried, and evaluated across multiple layers. For cross-tag set querying and statistical evaluation, ANNIS uses the ontology of linguistic annotations. Finally, ANNIS is also tied to a machine learning component for semiautomatic annotation.
Empirical studies of text coherence often use tree-like structures in the spirit of Rhetorical Structure Theory (RST) as representational device. This paper identifies several sources of ambiguity in RST-inspired trees and argues that such structures are therefore not as explanatory as a text representation should be. As an alternative, an approach toward multi-level annotation (MLA) of texts is proposed, which separates the information into distinct levels of representation, in particular: referential structure, thematic structure, conjunctive relations, and intentional structure. Levels are conceptually built upon each other, and human annotators can produce them using a dedicated software environment. We argue that the resulting multi-level corpora are descriptively more adequate, and as a resource are more useful than RST-style treebanks.
A production study is presented that investigates the effects of word order and information structural context on the prosodic realization of declarative sentences in Hindi. Previous work on Hindi intonation has shown that: (i) non-final content words bear rising pitch accents (Moore 1965, Dyrud 2001, Nair 1999); (ii) focused constituents show greater pitch excursion and longer duration and that post-focal material undergoes pitch range reduction (Moore 1965, Harnsberger 1994, Harnsberger and Judge 1996); and (iii) focused constituents may be followed by a phrase break (Moore 1965). By means of a controlled experiment, we investigated the effect of focus in relation to word order variation using 1200 utterances produced by 20 speakers. Fundamental frequency (F0) and duration of constituents were measured in Subject-Object-Verb (SOV) and Object-Subject-Verb (OSV) sentences in different information structural conditions (wide focus, subject focus and object focus). The analyses indicate that (i) regardless of word order and focus, the constituents are in a strict downstep relationship; (ii) focus is mainly characterized by post-focal pitch range reduction rather than pitch raising of the element in focus; (iii) given expressions that occur pre-focally appear to undergo no reduction; (iv) pitch excursion and duration of the constituents is higher in OSV compared to SOV sentences. A phonological analysis suggests that focus affects pitch scaling and that word order influences prosodic phrasing of the constituents.
The influence of information structure on tonal scaling in German is examined experimentally. Eighteen speakers uttered a total of 2277 sentences of the same syntactic structure, but with a varying number of constituents, word order and focus-given structure. The quantified results for German support findings for other Germanic languages that the scaling of high tones, and thus the entire melodic pattern, is influenced by information structure. Narrow focus raised the high tones of pitch accents, while givenness lowered them in prenuclear position and canceled them out postnuclearly. The effects of focus and givenness are calculated against all-new sentences as a baseline, which we expected to be characterized by downstep, a significantly lower scaling of high tones as compared to declination. The results further show that information structure alone cannot account for all variations. We therefore assume that dissimilatory tonal effects play a crucial role in the tonal scaling of German. The effects consist of final f0 drop, a steep fall from a raised high tone to the bottom line of the speaker, H-raising before a low tone, and H-lowering before a raised high tone. No correlation between word order and tone scaling could be established. 2008 Elsevier Ltd. All rights reserved.
The comprehension of figurative language : electrophysiological evidence on the processing of irony
(2008)
This dissertation investigates the comprehension of figurative language, in particular the temporal processing of verbal irony. In six experiments using event-related potentials(ERP) brain activity during the comprehension of ironic utterances in relation to equivalent non-ironic utterances was measured and analyzed. Moreover, the impact of various language-accompanying cues, e.g., prosody or the use of punctuation marks, as well as non-verbal cues such as pragmatic knowledge has been examined with respect to the processing of irony. On the basis of these findings different models on figurative language comprehension, i.e., the 'standard pragmatic model', the 'graded salience hypothesis', and the 'direct access view', are discussed.
The present dissertation focuses on the question whether and under which conditions infants recognise clauses in fluent speech and the role a prosodic marker such as a pause may have in the segmentation process. In the speech signal, syntactic clauses often coincide with intonational phrases (IPhs) (Nespor & Vogel, 1986, p. 190), the boundaries of which are marked by changes in fundamental frequency (e.g., Price, Ostendorf, Shattuck-Hufnagel & Fong, 1991), lengthening of the final syllable (e.g., Cooper & Paccia-Cooper, 1980) and the occurrence of a pause (Nespor & Vogel, 1986, p. 188). Thus, IPhs seem to be reliably marked in the speech stream and infants may use these cues to recognise them. Furthermore, corpus studies on the occurrence and distribution of pauses have revealed that there is a strong correlation between the duration of a pause and the type of boundary it marks (e.g., Butcher, 1981, for German). Pauses between words are either non-existent or short, pauses between phrases are a bit longer, and pauses between clauses and at sentence boundaries further increase in duration. This suggests the existence of a natural pause hierarchy that complements the prosodic hierarchy described by Nespor and Vogel (1986). These hierarchies on the side of the speech signal correspond to the syntactic hierarchy of a language. In the present study, five experiments using the Headturn preference paradigm (Hirsh-Pasek, Kemler Nelson, Jusczyk, Cassidy, Druss & Kennedy, 1987) were conducted to investigate German-learning 6- and 8-month-olds’ use of pauses to recognise clauses in the signal and their sensitivity to the natural pause hierarchy. Previous studies on English-learning infants’ recognition of clauses (Hirsh-Pasek et al., 1987; Nazzi, Kemler Nelson, Jusczyk & Jusczyk, 2000) have found that infants as young as 6 months recognise clauses in fluent speech. Recently, Seidl and colleagues have begun to investigate the status the pause may have in this process (Seidl, 2007; Johnson & Seidl, 2008; Seidl & Cristià, 2008). However, none of these studies investigated infants’ sensitivity to the natural pause hierarchy and especially the sensitivity to the correlation between pause durations and the respective within-sentence clause boundaries / sentence boundaries. To address these questions highly controlled stimuli were used. In all five experiments the stimuli were sentences consisting of two IPhs which each coincided with a syntactic clause. In the first three experiments pauses were inserted either at clause and sentence boundaries or within the first clause and the sentence boundaries. The duration of the pauses varied between the experiments. The results show that German-learning 6-month-olds recognise clauses in the speech stream, but only in a condition in which the duration of the pauses conforms to the mean duration of pauses found at the respective boundaries in German. Experiments 4 and 5 explicitly addressed the question of infants’ sensitivity to the natural pause hierarchy by inserting pauses at the clause and sentence boundaries only. Their durations were either conforming to the natural pause hierarchy or were being reversed. The results of these experiments provide evidence that 8-, but not 6-month-olds seem to be sensitive to the correlation of the duration of pauses and the type of boundary they demarcate. The present study provides first evidence that infants not only use pauses to recognise clause and sentence boundaries, but are sensitive to the duration and distribution of pauses in their native language as reflected in the natural pause hierarchy.
In der neurologischen Rehabilitation werden in zunehmendem Maße tracheotomierte Patienten mit schweren Dysphagien behandelt. Daher sollte den hierzu bisher entwickelten Interventionsverfahren eine evidenzbasierte Grundlage gegeben werden. In der vorliegenden Arbeit wird ein multidisziplinärer Behandlungsansatz zur Trachealkanülenentwöhung und Dekanülierung vorgestellt, der auf der Grundlage der relevanten Forschungsliteratur und klinischen Beobachtungen entwickelt wurde. Des Weiteren wird erstmals eine systematische Evaluation eines multidisziplinären Trachealkanülenmangements vorgenommen und es werden explorative Daten zum Rehabilitationsverlauf dargestellt. In einem retrospektiven Vergleich wurden hierzu die Dekanülierungs- und Komplikationsraten sowie die Dauer der Trachealkanülenentwöhnung zweier Patientengruppen gegenübergestellt, die vor bzw. nach Einführung des beschriebenen multidisziplinären Trachealkanülenmanagements im REHAB Basel, Schweiz, behandelt wurden. Der rehabilitative Verlauf der multidisziplinär behandelten Gruppe wurde mittels der Messinstrumente FIM (Functional Independence Measure) und EFA (Early Functional Abilities) untersucht. Der Vergleich der Dekanülierungs- und Komplikationsraten ergab eine vergleichbare Effektivität der beiden Behandlungsansätze. Darüber hinaus zeigte sich eine signifikante Verkürzung der Kanülenentwöhnungsphase bei Anwendung des multidisziplinären Vorgehens, so dass dieses als effizenter zu beurteilen ist. Die Verlaufsanalyse der multidisziplinär behandelten Patienten ergab erst nach der Dekanülierung einen signifikanten Zuwachs der funktionellen Selbständigkeit in Alltagsaktivitäten. Bei der Mehrzahl der Patienten konnte ein vollständiger oraler Kostaufbau nach der Dekanülierung erreicht werden.
