This thesis primarily investigates an (hitherto unnoticed) agreement alternation between Romance and Germanic in D>N>&>N constructions (e.g. “these walls and ceiling”). While Romance exhibits left conjunct agreement, Germanic shows morphologically resolved agreement on the determiner, i.e. the phi-feature mismatching conjuncts can only be licensed if a syncretic form is available. To handle these data the author suggests a theory in which coordination is syntactically and morphologically unspecified and multiple agree is a general option. Infelicitous derivations are ruled out by interface conditions on the semantic and the phonological well formedness. The complete results of the corpus research conducted to deliver a sound empirical basis for the phenomena investigated in this thesis can be found in the appendix.
Im Mittelpunkt der Dissertation steht die Untersuchung der Sprachförderkompetenz von Grundschullehrkräften aus linguistischer Perspektive. Dabei geht es um Grundschullehrkräfte, die in der vorschulischen Sprachförderung, v.a. von Kindern mit Deutsch als früher Zweitsprache (DaZ), im Rahmen sogenannter Vorlaufkurse in Hessen tätig sind. Anhand von zwei zentralen Dimensionen professioneller Kompetenz, dem Wissen und dem Handeln, werden in zwei empirischen Studien anhand einer Gruppe von 10 Lehrkräften der Umfang des sprachlichen Fachwissens und verschiedene Eigenschaften des sprachlichen Handelns in der Interaktion mit DaZ-Kindern im Vorlaufkurs untersucht. Zudem werden mögliche Zusammenhänge zwischen Wissen und Handeln sowie Unterschiede und Gemeinsamkeiten hinsichtlich beider Dimensionen zu pädagogischen Fachkräften aus dem Elementarbereich geprüft.
This thesis investigates the acquisition of compositional and lexical semantic properties of adjectives in German-speaking children between the age of two and five years.
According to formal semantic approaches, there are intersective and non-intersective adjectives, subsective and non-subsective adjectives as well as gradable and non-gradable adjectives. These properties concern the compositional mechanisms involved in nominal modification, i.e., the combination of adjectives and nouns. In addition, adjectives differ regarding lexical semantic properties that contribute to the adjectives' meaning. Differences in the adjectives' scale structure have led to the theoretical assumption that gradable adjectives should be distinguished into relative and absolute gradable adjectives. In addition, meaning components such as multidimensionality or subjectivity have led to the distinction between dimensional and evaluative gradable adjectives. These properties have been mostly investigated independently of each other in both theory and acquisition research. I suggest a classification system for adjectives that combines different semantic properties. This system results in six adjective classes constituting a Semantic Complexity Hierarchy. Assuming that these adjective classes differ in semantic complexity, I propose an operationalization of semantic complexity that takes into account the adjectives' length of description, their type complexity, and lexical properties that contribute to the adjectives' meaning.
Regarding the question of how monolingual German-speaking children acquire the semantics of adjectives, I hypothesize that the order of acquisition of adjectives is determined by their semantic complexity. This hypothesis is tested in a spontaneous speech study and a comprehension experiment.
The spontaneous speech study is a longitudinal investigation of the production of adjectives from 2;00 to 2;11 years based on transcripts from a dense data corpus. The results provide evidence that the mean age of acquisition for the adjective classes in the Semantic Complexity Hierarchy follows the order predicted by semantic complexity. The same order was observed for the age at which the number of types for each class increased most. A preliminary analysis of the input indicates that the frequency of parental adjective use is related to the order of acquisition, but it is unlikely that frequency determines the order completely.
The comprehension experiment focuses on two specific adjective classes. I examine children's and adults' interpretation of relative (big, small) and absolute (clean, dirty) gradable dimensional adjectives with a picture-choice task. These two classes are of the same semantic complexity because they are both gradable, but they have different scale structures. As a result, they must be interpreted differently due to lexical semantic properties. I investigate whether children calculate different standards of comparison for relative and absolute gradable adjectives and whether they distinguish between relative and absolute gradable adjectives regarding the relevance of the explicit comparison class. The results indicate that as of age 3, children distinguish between relative and absolute gradable adjectives with regard to the standard of comparison. However, with respect to the relevance of the comparison class, for 3-year-old children, unlike for 4- and 5-year-olds, changes in the noun, i.e., in the explicit comparison class, led to non-adult-like responses regarding both relative and absolute gradable adjectives.
On the basis of the empirical findings, I propose an acquisition path stating that children enter the acquisition process with inherent linguistic knowledge, the Semantic Complexity Hierarchy, and cognitive abilities to categorize their environment. I suggest that initially, children apply the least complex interpretation available in the Semantic Complexity Hierarchy to all adjectives: all adjectives are interpreted as properties of individuals that are not gradable. To access other levels of the Semantic Complexity Hierarchy and to establish more complex adjective classes, positive evidence from the input and conceptual properties of adjectives, e.g., COLOR, MENTAL STATE, PHYSICAL PROPERTY etc., can operate as triggers.
Individuelle sprachliche Repertoires und gesellschaftliche Mehrsprachigkeit in der Republik Moldova
(2016)
Die sprachlichen Verhältnisse in der Republik Moldau befinden sich seit der Unabhängigkeit von der Sowjetunion in Veränderung. Maßgeblich hierfür sind eine neue offizielle Sprache, die Förderung der Minderheitensprachen und die Arbeitsmigration. Die Autorin untersucht die Frage, wie Sprecher*innen mit unterschiedlichen sprachlichen Repertoires mit diesen Veränderungen umge-hen. Sie zeigt dies am Beispiel ausgewählter Sprach- und Berufsbiographien in zwei exemplarischen Fallstudien: einem russisch-ukrainisches Lyzeum und einem italienischsprachigen Call-Center.Mit den Begriffen Erreichbarkeit und Reichweite leistet das Buch einen theo-retischen Beitrag zur Diskussion um sprachliche Repertoires und sprachlichen Ausbau, indem sie den Zusammenhang zwischen gesellschaftlichen Verände-rungen und den individuellen Aneignungsprozessen von Sprecher*innen zu begreifen helfen.
This dissertation is an investigation of pitch accent, or lexical tone, in standard Croatian. The first chapter presents an in-depth overview of the history of the Croatian language, its relationship to Serbo-Croatian, its dialect groups and pronunciation variants, and general phonology. The second chapter explains the difference between various types of prosodic prominence and describes systems of pitch accent in various languages from different parts of the world: Yucatec Maya, Lithuanian and Limburgian. Following is a detailed account of the history of tone in Serbo-Croatian and Croatian, the specifics of its tonal system, intonational phonology and finally, a review of the most prominent phonetic investigations of tone in that language.
The focal point of this dissertation is a production experiment, in which ten native speakers of Croatian from the region of Slavonia were recorded. The material recorded included a diverse selection of monosyllabic, bisyllabic, trisyllabic and quadrisyllabic words, containing all four accents of standard Croatian: short falling, long falling, short rising and long rising. Each target word was spoken in initial, medial and final positions of natural Croatian sentences. This research fills several gaps in the existing literature. Namely, the production of tone was investigated in words with a syllabic /r̩/, in pretonal syllables and in non-initial context. Acoustic parameters measured included duration, F0 in every 10% of the nucleus duration, overall pitch, pitch range and pitch peak alignment.
Results showed that differences between falling and rising accents in Croatian are produced mainly with tonal parameters and that the most salient features were pitch peak alignment and overall pitch. The difference between long and short accents was primarily durational and optionally tonal. Words produced in initial and medial sentence positions had a rising contour in their accented syllable, while in the final, segments were usually falling.
This research investigated variation in the pronunciations of three RP vowels phonemes /e/, /ɜ:/ and /ə/, among Ewe speakers of English in Ghana. It focused on variation at both individual and societal levels, investigating how social relations within these structures influenced the use of the three vowels among the speakers. In this study, social structures were seen as a system where individual members depended on one another and were linked through multiple ties. The distribution of the vowels was in respect with the social variables: age, gender and education, including dialect and social network. The study used a corpus of word-list recorded in a face-to-face interview from 96 participants selected through stratification and networking across two dialect regions: Aŋlɔ and Eveme. Using both aural and acoustic analyses, coupled with ANOVA and t-test, the study has shown that the three RP vowels exist in Ghana Eve English as independent phonemes. Each of them however has allophonic variants; /e/ has variants [e̠], [ɪ] and [ɜ:]; /ɜ:/ has [eː] and [ɜ:], while /ə/ has [ə], [ɪ], [o] and [ʌ] as its variants. The choice of the variants of /ɜ:/ and /e/ have been found to depend on speaker age, gender, and social network. But the geographical location of the speaker will largely determine how these vowels are spoken. Phonological contexts as well as speaker idiosyncrasy are also likely to condition the choice of some of these variants, however, their effects seem less important as determinant of the differences observed than those of the social factors. It is evident that age, gender and class differentiations that have been widely reported cannot be universal, they can vary from one society to another. Also though social structures as well as social relations in a speech community can play significant roles in the individual’s linguistic repertoire, the attitude of the speaker and the phonological contexts of a segment can have a huge impact on the use of that variable.
Exploring the ability of acoustic infant cry analysis for discriminating developmental pathologies
(2018)
This thesis aims at exploring the ability of acoustic infant cry analysis for discriminating developmental pathologies. Cries of healthy infants as well as cries of infants suffering from cleft lip and palate, hearing impairment, laryngomalacia, asphyxia and brain damage were recorded and acoustically analyzed. The acoustic properties of the infant cries were identified and tested on their suitability to predict the health state of the infants in an reliable, valid and objective way.
To test the reliability of infant cry analysis, Krippendorff’s Alpha coefficient was calculated to test how homogeneous cries of healthy infants as well as cries of infants suffering from various pathologies are.
To asses if valid methods exist for classifying infant cries, different approaches that can be used to differentiate between the groups and to predict the health state of the infants — e.g., analysis of variances, supervised-learning models and auditory discrimination by human listeners — were tested on their validity.
The objectivity of computer-based and human-based classification approaches was explored and techniques to enhance the objectivity for both approaches are proposed.
Computer-based approaches are more objective and reached higher sensitivity and specificity values in their classification to predict the health state of the infants. Especially C5.0 decision trees reached high and therefore promising classification results, even though infant cries have a great statistical spread and can be seen as very heterogeneous and are therefore not very reliable in general.
Ziel der Arbeit ist es, den frühen Zweitspracherwerb bei Kinder mit einer Spezifischen Sprachentwicklungsstörung (specific language impairment, SLI) zu charakterisieren. Im Vergleich zwischen sprachunauffälligen Kindern mit Deutsch als Zweitsprache (DaZ-TD) und und sprachauffälligen Kindern (DaZ-SLI) wird für die morpho-syntaktischen Bereiche Finitheit und Verbstellung sowie Kasus untersucht, anhand welcher Entwicklungsmuster sich zwischen einem unauffälligen und einem auffälligen DaZ-Erwerb unterscheiden lässt. Dabei werden die folgenden übergeordneten Fragen (F) beantwortet. (F1) Gibt es Unterschiede in Bezug auf Fehlerarten und -häufigkeiten zwischen DaZ-TD und DaZ-SLI Kindern? (F2) Gibt es persistierende Defizite bei DaZ-SLI Kindern verglichen mit DaZ-TD Kindern?
Untersucht wurden über einen Zeitraum von zwei Jahren 33 DaZ-Kinder, elf davon mit einer SLI. Zu Beginn der Erhebungen waren die DaZ-TD Kinder im Durchschnitt 3;8 Jahre alt und hatten 11 KM zum Deutschen. Die DaZ-SLI waren zu MZP 1 durchschnittlich 7;1 Jahre alt (45 KM). Zu insgesamt vier MZP wurden elizitierte Produktionsdaten mittels des standardisierten Verfahrens LiSe-DaZ (Schulz & Tracy 2011) erhoben. Sowohl die Methode der elizitierten Produktion als auch die längsschnittlichen Analysen einer großen Gruppe von Kindern mit DaZ erlaubten es, Aussagen über das Erwerbsalter bzw. persistierende Defizite und Entwicklungsmuster, insbesondere bei SLI, zu treffen. Entwicklungsverzögerungen (delay) und ggf. vom DaZ-TD Erwerb abweichende Entwicklungsmuster (deviance) wurden abgebildet.
Mit der Beantwortung der Fragen leistet die Arbeit in zweierlei Hinsicht einen Beitrag. Erstens wird mit Blick auf die Spracherwerbsforschung gezeigt, dass DaZ-SLI Kinder entwicklungsverzögert sind und sowohl ø-Stämme in V2 als auch Schwierigkeiten im Erwerb von Dativ in Präpositionalphrasen auf eine SLI bei Kindern mit DaZ hinweisen. Zweitens wird aus Sicht der Linguistik dafür argumentiert, dass zum einen ø-Stämme in V2 kovert finit sind und zum anderen in Modellen der Kasuszuweisung von einer dreigliedrigen Struktur, also einer Unterscheidung zwischen strukturellem, lexikalischem und inhärentem Kasus, ausgegangen werden muss.
Die Arbeit knüpft an damit an verschiedene Erwerbsstudien an. Hinsichtlich des Erwerbs von Finitheit und Verbstellung war bisher ungeklärt, ob auch die DaZ-SLI Kinder zwischen en-Infinitiven und ø-Stämmen hinsichtlich der jeweiligen Position im Satz unterscheiden, wie bereits für den DaZ-TD Erwerb nachgewiesen. Die vorliegende Studie wies dieses Erwerbsmuster auch für den DaZ-SLI Erwerb nach und schließt sich damit bisherigen Studien hinsichtlich kovert finiter ø-Stämme in V2 an. Studien zum Kasuserwerb bei DaZ, die auf den linguistisch relevanten Unterschied in der Kasuszuweisung, d.h. strukturell vs. nicht-strukturell (inhärent und lexikalisch), eingehen, gab es nur wenige. Die Frage, ob in der Kasustheorie von einem zwei- oder dreigliedrigen Modell ausgegangen werden muss, war neben der Frage nach möglicherweise abweichenden Erwerbsmustern und persistierenden Erwerbsschwierigkeiten bei DaZ-SLI bislang ungeklärt. In der vorliegenden Studie wurde gezeigt, dass DaZ-SLI Kinder verglichen mit DaZ-TD Kindern ähnliche Fehlermuster zeigen, aber insbesondere der Dativ in PPs stark verzögert erworben wird. Die Studie schließt den Ergebnissen zum simultan bilingualen Erwerb an und postuliert ein dreigliedriges Kasussystem.
Insgesamt zeigt die vorliegende Studie erstmals anhand elizitierter Längsschnittdaten, dass DaZ-SLI Kinder bis ins Schulalter persistierende Probleme im Erwerb von Finitheit und Verbstellung sowie Kasus haben. Verglichen mit DaZ-TD Kindern erwerben sie diese Bereiche - wenn überhaupt - deutlich verzögert (delay). In den Fehlertypen unterscheiden sich die beiden Erwerbstypen hingegen nicht (deviance).
The linguistic deficit in patients with Alzheimer's Disease: is there a syntactic impairment?
(2017)
The linguistic impairment of patients affected by Alzheimer’s disease (PAD) is defined as a form of fluent aphasia, which is caused by major disruptions in the semantic and lexical domains. Consequently, their discourse is often described as empty, although their speech is fluent. This study aims at enlarging the comprehension of the linguistic deficit in PADs; in particular, it deals with their syntactic competence and it addresses the following questions: 1) Do PADs suffer from syntactic impairment? 2) How can the impairment in PADs be accounted for? 3) At which stage of the disease are PADs affected by syntactic impairment? The syntactic competence of Italian-speaking PADs is investigated under two different perspectives. On one hand, the study considers the syntactic information stored in the lexicon as part of the lexical entry. For this purpose, PADs complete a grammatical gender retrieval task on a list of 100 Italian nouns. On the other hand, the question deals with syntax intended as the capacity to complete the processing of syntactic structures in sentence comprehension and production. The present study focuses on sentence comprehension and includes two sentence-to-picture matching tasks: one on Wh-questions, and one on relative clauses. PADs complete the experiment on grammatical gender retrieval with high accuracy, except for few mistakes on irregular and opaque nouns, thus showing a spared capacity to retrieve the syntactic information, especially when they can rely on the form-driven procedural mechanism, as in the case of regular nouns. Data on the comprehension of Wh-questions and RC reveals that PADs are more sensitive than controls to locality effects. Patients with moderate dementia are impaired at computing dependencies that entail a crossing movement between two arguments whose features are in a relation of inclusion. In contrast, crossing movements are allowed when the involved feature arrays are in a relation of disjunction. In short, patients are spared at using procedural mechanisms for the retrieval of syntactic information, while they are impaired at processing sentences that entail argument extraction. The impairment manifests itself in moderately impaired PADs in the form of enhanced sensitivity to locality effects.
This dissertation explores the linguistic identity changes of Chinese international students in Germany, and the relationship between their identity reconstruction and their multilingual competence. With the social turn (Block, 2003) of applied linguistics, research on study abroad has shown that student sojourners abroad encounter challenges not only to their language abilities, but also to their identities, which explains the vast individual differences in the measurable outcomes of student sojourns abroad. However, the realm of learners’ linguistic identity development in the English as a lingua franca (ELF) and multilingual contexts remains to be further explored, since most existing studies examined learners in the target language community. Guided by poststructuralist views and sociocultural theories, this study is designed with a view towards investigating the lived experience of Chinese international students at German universities.
Employing a qualitative approach, my research tracked seventeen Chinese students’ experiences of language learning and use in both their social lives and academic settings over one year. The empirical work combined semi-structured, in-depth interviews and emails. Three rounds of one-to-one interviews were conducted every 6 months and each round focused on students’ respective past, present and future. The grounded theory approach (Corbin & Strauss, 2015) was used in this study to analyse the data, aiming at generating theoretical explanations for phenomena through constant comparison.
The results of the category-based analysis offer a new lens on the intricate linguistic identity development of Chinese students in the study abroad context. The construction of their new identity facets is related to various contextual elements in experiences of their language learning and use. More importantly, learners’ identity changes related to the use of ELF is conceived as within a framework of multilingualism (Jenkins, 2015). In any given social interaction, learners’ linguistic identities are influenced by a combination of factors: perceived linguistic proficiency gap, power distribution,preferred communication styles, sensitivity to second/third language self-images and openness to new cultures. It is these factors, instead of the lingua franca context or
target language context per se, that come into play in the reformation of learners’
linguistic identities. Learners’ linguistic identity changes, together with their priority setting in studying abroad, are in turn interconnected with their multilingual competence development.
The findings of my study suggest theories for understanding learners’ linguistic identity development and the outcomes of their language learning in the study abroad context in the face of the complexity of individual experiences. My study also demonstrates the importance to foster learners’ “self-presentational competence” (Pellegrino Aveni, 2005: 145-146) so that they could successfully negotiate new subject positions when crossing the borders.
