  abstract  = {This paper presents an overview of the linguistic analyses developed in the MULTILIT project and the processing of the oral and written texts collected. The project investigates the language abilities of multilingual children and adolescents, in particular, those who have Turkish and/or Kurdish as a mother tongue. A further aim of the project is to examine from a psycholinguistic and sociolinguistic perspective the extent to which competence in academic registers is achieved on the basis of the languages spoken by the children, including the language(s) spoken at the home, the language of the country of residence and the first foreign language. To be able to examine these questions using corpus linguistic parameters, we created categories of analysis in MULTILIT. The data collection comprises texts from bilingual and monolingual children and adolescents in Germany in their first language Turkish, their second language German und their foreign language English. Pupils aged between nine and twenty years of age produced monologue oral and written texts in the two genres of narrative and discursive. On the basis of these samples, we examine linguistic features such as lexical expression (lexical density, lexical diversity), syntactic complexity (syntactic and discursive packaging) as well as phonology in the oral texts and orthography in the written texts, with the aim of investigating the pupils' growing mastery of these features in academic and informal registers. To this end the raw data have been transcribed by the use of transcription conventions developed especially for the needs of the MULTILIT data. They are based on the commonly used HIAT and GAT transcription conventions and supplemented with conventions that provide additional information such as features at the graphic level. The categories of analysis comprise a large number of linguistic categories such as word classes, syntax, noun phrase complexity, complex verbal morphology, direct speech and text structures. We also annotate errors and norm deviations at a wide range of levels (orthographic, morphological, lexical, syntactic and textual). In view of the different language systems, these criteria are considered separately for all languages investigated in the project.},

  abstract  = {This dissertation investigates the working memory mechanism subserving human sentence processing and its relative contribution to processing difficulty as compared to syntactic prediction. Within the last decades, evidence for a content-addressable memory system underlying human cognition in general has accumulated (e.g., Anderson et al., 2004). In sentence processing research, it has been proposed that this general content-addressable architecture is also used for language processing (e.g., McElree, 2000). Although there is a growing body of evidence from various kinds of linguistic dependencies that is consistent with a general content-addressable memory subserving sentence processing (e.g., McElree et al., 2003; VanDyke2006), the case of reflexive-antecedent dependencies has challenged this view. It has been proposed that in the processing of reflexive-antecedent dependencies, a syntactic-structure based memory access is used rather than cue-based retrieval within a content-addressable framework (e.g., Sturt, 2003). Two eye-tracking experiments on Chinese reflexives were designed to tease apart accounts assuming a syntactic-structure based memory access mechanism from cue-based retrieval (implemented in ACT-R as proposed by Lewis and Vasishth (2005). In both experiments, interference effects were observed from noun phrases which syntactically do not qualify as the reflexive's antecedent but match the animacy requirement the reflexive imposes on its antecedent. These results are interpreted as evidence against a purely syntactic-structure based memory access. However, the exact pattern of effects observed in the data is only partially compatible with the Lewis and Vasishth cue-based parsing model. Therefore, an extension of the Lewis and Vasishth model is proposed. Two principles are added to the original model, namely 'cue confusion' and 'distractor prominence'. Although interference effects are generally interpreted in favor of a content-addressable memory architecture, an alternative explanation for interference effects in reflexive processing has been proposed which, crucially, might reconcile interference effects with a structure-based account. It has been argued that interference effects do not necessarily reflect cue-based retrieval interference in a content-addressable memory but might equally well be accounted for by interference effects which have already occurred at the moment of encoding the antecedent in memory (Dillon, 2011). Three experiments (eye-tracking and self-paced reading) on German reflexives and Swedish possessives were designed to tease apart cue-based retrieval interference from encoding interference. The results of all three experiments suggest that there is no evidence that encoding interference affects the retrieval of a reflexive's antecedent. Taken together, these findings suggest that the processing of reflexives can be explained with the same cue-based retrieval mechanism that has been invoked to explain syntactic dependency resolution in a range of other structures. This supports the view that the language processing system is located within a general cognitive architecture, with a general-purpose content-addressable working memory system operating on linguistic expressions. Finally, two experiments (self-paced reading and eye-tracking) using Chinese relative clauses were conducted to determine the relative contribution to sentence processing difficulty of working-memory processes as compared to syntactic prediction during incremental parsing. Chinese has the cross-linguistically rare property of being a language with subject-verb-object word order and pre-nominal relative clauses. This property leads to opposing predictions of expectation-based accounts and memory-based accounts with respect to the relative processing difficulty of subject vs. object relatives. Previous studies showed contradictory results, which has been attributed to different kinds local ambiguities confounding the materials (Lin and Bever, 2011). The two experiments presented are the first to compare Chinese relatives clauses in syntactically unambiguous contexts. The results of both experiments were consistent with the predictions of the expectation-based account of sentence processing but not with the memory-based account. From these findings, I conclude that any theory of human sentence processing needs to take into account the power of predictive processes unfolding in the human mind.},

  abstract  = {Gegenstand der Dissertation ist die Untersuchung der Gewichtung prosodischer Korrelate der Phrasierung im Deutschen, insbesondere der Dauer- und Grundfrequenzeigenschaften auf der Ebene der phonologischen Phrase (φ) und der Intonationsphrase (ι). F{\"u}r die prosodische Dom{\"a}ne der phonologischen Phrase und der Intonationsphrase gilt als belegt, dass sie h{\"a}upts{\"a}chlich durch phonetische Parameter der pr{\"a}finalen Dehnung (Lehiste, 1973; Klatt, 1976; Price et al., 1991; Turk \& White, 1999), der Pausendauer (Fant \& Kruckenberg, 1996) und der Ver{\"a}nderung der Grundfrequenz (Pierrehumbert, 1980) ausgedr{\"u}ckt werden, wobei die phonetischen grenzmarkierenden Eigenschaften eher quantitativer als qualitativer Natur sind. Ebenfalls ist bekannt, dass auf der anderen Seite H{\"o}rer diese phonetischen Eigenschaften der Sprecher nutzen, um die prosodische Struktur einer {\"A}ußerung zu ermitteln (Snedeker \& Trueswell, 2003; Kraljic \& Brennan, 2005). Perzeptuelle Evidenz aus dem Englischen und Niederl{\"a}ndischen deuten allerdings darauf hin, dass sich Sprachen hinsichtlich der entscheidenden Korrelate, die f{\"u}r die Perzeption der Dom{\"a}nen konsultiert werden, unterscheiden (Aasland \& Baum, 2003; Sanderman \& Collier, 1997; Scott, 1982; Streeter, 1978). Die grenzmarkierenden phonetischen Korrelate der Dom{\"a}nen werden in der Perzeption unterschiedlich stark gewichtet, was sich im Konzept eines sprachspezifischen prosodischen cue weightings ausdr{\"u}ckt. F{\"u}r das Deutsche ist allerdings nicht hinreichend bekannt, welche dieser drei phonetischen Parameter die wichtigste Rolle f{\"u}r die Perzeption der phonologischen Phrasengrenze und der Intonationsphrasengrenze spielt. Ziel der Dissertation war es, diejenigen phonetischen Merkmale zu identifizieren, die f{\"u}r die Perzeption der phonologischen Phrasengrenze und der Intonationsphrasengrenze entscheidend sind und sich somit f{\"u}r die Bildung der jeweiligen prosodischen Phrasengrenze als notwendig herausstellen. Die Identifikation und Gewichtung eines phonetischen Merkmals erfolgte in der vorliegenden Arbeit durch die Effekte prosodischer Manipulation der phonetischen Korrelate an phonologischen Phrasengrenzen und Intonationsphrasengrenzen auf die Disambiguierung lokaler syntaktischer Ambiguit{\"a}ten in der Perzeption. Der Einfluss einzelner phonetischer Merkmale wurde in einem forced-choice Experiment evaluiert, bei dem H{\"o}rern syntaktisch ambige Satzfragmente auditiv pr{\"a}sentiert wurden und ihnen anschließend die Aufgabe zukam, aus einer Auswahl an disambiguierenden Satzvervollst{\"a}ndigung zu w{\"a}hlen. Die Anzahl der ausgew{\"a}hlten Satzvervollst{\"a}ndigungen pro Satzbedingung {\"a}nderte sich in Abh{\"a}ngigkeit der prosodischen Manipulation der pr{\"a}finalen Dehnung, der Pausendauer und der Grundfrequenz, wodurch der Einfluss eines einzelnen phonetischen Merkmals auf den Disambiguierungsprozess sichtbar wurde. Ein phonetischer Parameter wurde genau dann als notwendig klassifiziert, wenn sich durch seine Manipulation die F{\"a}higkeit zur Disambiguierung der syntaktischen Strukturen signifikant reduzierte, oder g{\"a}nzlich scheiterte, und somit die Wahrnehmung prosodischer Kategorien beinflusst wurde (Heldner, 2001). Hat sich in der Perzeption ein phonetisches Merkmal als notwendig herausgestellt, wurde nachfolgend eine optimalit{\"a}tstheoretische Modellierung vorgeschlagen, die die phonetischen Eigenschaften auf eine (abstrakte) phonologische Strukturerstellung beschreibt. Dieser Verarbeitungsschritt entspricht dem Teilbereich des Perzeptionsprozesses, der in Boersma \& Hamann (2009), Escudero (2009) und F{\´e}ry et al. (2009) unter anderen als Phonetik-Phonologie-Mapping beschrieben wird. Die Dissertation hat folgende Hauptergebnisse hervorgebracht: (1) F{\"u}r die Perzeption phonologischer Phrasengrenzen und Intonationsphrasengrenzen werden nicht alle messbaren phonetischen Grenzmarkierungen gleichermaßen stark genutzt. Das phonetische Merkmal der pr{\"a}finalen Dehnung ist auf der Ebene der kleineren prosodischen Dom{\"a}ne, der phonologischen Phrase, notwendig. Die Information der Grundfrequenz in der Form von Grenzt{\"o}nen ist in der gr{\"o}ßeren Dom{\"a}ne der Intonationsphrase notwendig und damit ausschlaggebend f{\"u}r die Perzeption der prosodischen Phrasengrenze. (2) Auf der Ebene der φ-Phrase werden phonetische Eigenschaften der segmentalen Dauer in Form pr{\"a}finalen Dehnung zur Bildung abstrakter phonologischer Repr{\"a}sentationen herangezogen werden. L{\"a}ngenconstraints schreiben syntaktische Konstituenten aufgrund ihrer Inputdauern einer prosodischen Kategorie zu. Inputdauern der ersten Nominalphrase von 500ms und mehr signalisieren Finalit{\"a}t und sind durch eine φ- Grenze am rechten Rand markiert. Inputdauern von 400ms und weniger signalisieren Kontinuit{\"a}t und werden durch das Ausbleiben einer φ-Grenze am rechten Rand der ersten Nominalphrase markiert. Inputdauern, die zwischen den kritischen L{\"a}ngen von 400ms und 500ms variieren sind bez{\"u}glich der Bildung von φ- Grenzen ambig und k{\"o}nnen in der Perzeption nicht eindeutig disambiguiert werden. (3) Auf der Ebene der ι-Phrase wird die Bildung einer prosodischen Struktur durch die reine tonale Kontur (steigend oder fallend) an der ersten Nominalphrase gelenkt. Eine fallende Grundfrequenzkontur an der ersten Nominalphrase signalisiert Finalit{\"a}t und wird durch eine ι-Grenze am rechten Rand markiert. Eine steigende Kontur an der ersten Nominalphrase signalisiert phrasale Kontinuit{\"a}t und ist bei den vorliegenden S{\"a}tzen der Genitivbedingung gerade durch das Ausbleiben einer ι-Grenze auf der phonologischen Repr{\"a}sentationseben gekennzeichnet.},

  abstract  = {Sentences with doubly center-embedded relative clauses in which a verb phrase (VP) is missing are sometimes perceived as grammatical, thus giving rise to an illusion of grammaticality. In this paper, we provide a new account of why missing-VP sentences, which are both complex and ungrammatical, lead to an illusion of grammaticality, the so-called missing-VP effect. We propose that the missing-VP effect in particular, and processing difficulties with multiply center-embedded clauses more generally, are best understood as resulting from interference during cue-based retrieval. When processing a sentence with double center-embedding, a retrieval error due to interference can cause the verb of an embedded clause to be erroneously attached into a higher clause. This can lead to an illusion of grammaticality in the case of missing-VP sentences and to processing complexity in the case of complete sentences with double center-embedding. Evidence for an interference account of the missing-VP effect comes from experiments that have investigated the missing-VP effect in German using a speeded grammaticality judgments procedure. We review this evidence and then present two new experiments that show that the missing-VP effect can be found in German also with less restricting procedures. One experiment was a questionnaire study which required grammaticality judgments from participants without imposing any time constraints. The second experiment used a self-paced reading procedure and did not require any judgments. Both experiments confirm the prior findings of missing-VP effects in German and also show that the missing-VP effect is subject to a primacy effect as known from the memory literature. Based on this evidence, we argue that an account of missing-VP effects in terms of interference during cue-based retrieval is superior to accounts in terms of limited memory resources or in terms of experience with embedded structures.},

  abstract  = {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 \& Cristi{\`a}, 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.},
