This dissertation examines the impact of the type of referring expression on the acquisition of word order variation in German-speaking preschoolers. A puzzle in the area of language acquisition concerns the production-comprehension asymmetry for non-canonical sentences like "Den Affen fängt die Kuh." (“The monkey, the cow chases.”), that is, preschoolers usually have difficulties in accurately understanding non-canonical sentences approximately until age six (e.g., Dittmar et al., 2008) although they produce non-canonical sentences already around age three (e.g., Poeppel & Wexler, 1993; Weissenborn, 1990). This dissertation investigated the production and comprehension of non-canonical sentences to address this issue. Three corpus analyses were conducted to investigate the impact of givenness, topic status and the type of referring expression on word order in the spontaneous speech of two- to four-year-olds and the child-directed speech produced by their mothers. The positioning of the direct object in ditransitive sentences was examined; in particular, sentences in which the direct object occurred before or after the indirect object in the sentence-medial positions and sentences in which it occurred in the sentence-initial position. The results reveal similar ordering patterns for children and adults. Word order variation was to a large extent predictable from the type of referring expression, especially with respect to the word order involving the sentence-medial positions. Information structure (e.g., topic status) had an additional impact only on word order variation that involved the sentence-initial position. Two comprehension experiments were conducted to investigate whether the type of referring expression and topic status influences the comprehension of non-canonical transitive sentences in four- and five-year-olds. In the first experiment, the topic status of the one of the sentential arguments was established via a preceding context sentence, and in the second experiment, the type of referring expression for the sentential arguments was additionally manipulated by using either a full lexical noun phrase (NP) or a personal pronoun. The results demonstrate that children’s comprehension of non-canonical sentences improved when the topic argument was realized as a personal pronoun and this improvement was independent of the grammatical role of the arguments. However, children’s comprehension was not improved when the topic argument was realized as a lexical NP. In sum, the results of both production and comprehension studies support the view that referring expressions may be seen as a sentence-level cue to word order and to the information status of the sentential arguments. The results highlight the important role of the type of referring expression on the acquisition of word order variation and indicate that the production-comprehension asymmetry is reduced when the type of referring expression is considered. --- Im Rahmen der vorliegenden Dissertation wurde der Einfluss des referierenden Ausdrucks auf den Erwerb von Wortstellungsvariationen bei deutschsprachigen Vorschulkindern untersucht. Eine zentrale Fragestellung im Spracherwerb betrifft die Asymmetrie zwischen Produktion und Verständnis. Diese Asymmetrie ist dadurch gekennzeichnet, dass sechsjährige Kinder oft Schwierigkeiten haben, Sätze in der nicht-kanonischen Wortstellung, z.B. „Den Affen fängt die Kuh.“, zu verstehen (z.B., Dittmar et al., 2008), obwohl bereits Dreijährige nicht-kanonische Sätze produzieren können (z.B., Poeppel & Wexler, 1993; Weissenborn, 1990). Um diese Asymmetrie zu untersuchen wurde in der Dissertation die Produktion und das Verständnis von nicht-kanonischen Sätzen betrachtet. In drei Korpusstudien wurde der Einfluss von Vorerwähntheit, Topikstatus und Wahl des referierenden Ausdrucks auf die Wortstellung in der Spontansprache von Zwei- bis Vierjährigen und in der kind-gerichteten Sprache ihre Mütter analysiert. Es wurde die Position des direkten Objektes in ditransitiven Sätzen untersucht, d.h., Sätze in denen das direkte Objekt vor oder nach dem indirekten Objekt in den satzmedialen Positionen stand, und Sätze in denen es in der satzinitialen Position stand. Die Ergebnisse zeigen ähnlich Abfolgemuster in der Satzproduktion der Kindern und Erwachsenen. Die Position des direkten Objektes, vor allem in den satzmedialen Positionen, war zu einem großen Teil durch die Wahl des referierenden Ausdrucks vorhersagbar. Informationsstrukturelle Faktoren (z.B. Topikstatus) hingegen beeinflussten - unabhängig vom Einfluss des referierenden Ausdrucks - nur die Wortstellung in der satzinitialen Position. Zwei Verständnisexperimente wurden durchgeführt um den Einfluss des referierenden Ausdrucks und des Topikstatuses auf das Verständnis von nicht-kanonischen transitiven Sätzen zu untersuchen. Im ersten Experiment wurde der Topikstatus eines der beiden Satzargumente durch einen vorherigen Kontext modifiziert. Im zweiten Experiment wurde zusätzlich der referierende Ausdruck modifiziert, d.h. das Topik wurde entweder durch eine lexikalische Nominalphrase (NP) oder ein Personalpronomen realisiert. Die Ergebnisse zeigen, dass vier- und fünfjährige Kinder Sätze in der nichtkanonischen Wortstellung besser verstehen konnten, wenn das Topik als Personalpronomen realisiert wurde, unabhängig von der grammatischen Rolle des Topiks. Das Satzverständnis war jedoch nicht verbessert, wenn das Topik als lexikalische NP realisiert wurde. Zusammengefasst zeigen die Ergebnisse der Produktions- und Verständnisstudien, dass der referierende Ausdruck als Hinweis auf die Wortstellung und auf den Informationsstatus der Argumente des Satzes von den Kindern genutzt werden kann. Sie unterstreichen somit die Bedeutung der Wahl des referierenden Ausdrucks auf den Erwerb von Wortstellungsvariation und zeigen, dass die Asymmetrie zwischen Produktion und Verständnis an Bedeutung verliert, wenn der referierende Ausdruck einbezogen wird.

This book contains 51 chapters based on papers presented at the GALA (Generative Approaches to Language Acquisition) conference held in Thessaloniki, Greece, in 2011. It thus reflects the GALA 2011 scientific presentations and discussions and raises issues that are currently at the centre of language acquisition research. Such issues examined in this volume include first and second language acquisition and processing by children and adults; language acquisition by individuals with linguistic and/or cognitive impairment; and cross-linguistic comparisons in (a)typical language acquisition. As such, Advances in Language Acquisition constitutes a valuable reference guide for current work on the interdisciplinary research field of language acquisition.

All normal humans have the same basic cognitive capacity for language. Nevertheless, the world's languages differ in the kind and number of grammatical options they give their speakers to express themselves with. Sometimes, a language's grammatical constructions may differ in how easy they are for comprehenders to process or how readily speakers will choose them. It has been observed that languages which allow more difficult constructions also tend to allow easier ones, and when a language only allows one option, it tends to allow the easiest to process. This correlation is intuitive: languages tend to give their speakers options that they find easy to use. However, the causal process that underlies it is not well understood. How did the world's languages come to have this convenient property? In this dissertation, I discuss a family of evolutionary models of language change in which processing-efficient variants tend to be selected more frequently, and hence over time have the potential to displace less efficient variants, pushing them out of the language. I begin by showing that a psycholinguistic theory, dependency length minimization, accounts for word ordering preferences in data taken from Old and Middle English just as it does in Present Day English. I then discuss computer simulations of a model of language change which implements this bias, predicting observed word order changes in English. Finally, I present experimental studies of online comprehension in Japanese which not only display evidence for the dependency length bias, but also suggest that comprehenders encode it as part of their knowledge about language, using it to help understand the sentences they receive from their peers.

This book provides linguists with a clear, critical, and comprehensive overview of theoretical and experimental work on information structure. Leading researchers survey the main theories of information structure in syntax, phonology, and semantics as well as perspectives from psycholinguistics and other relevant fields. Following the editors' introduction the book is divided into four parts. The first, on theories of and theoretical perspectives on information structure, includes chapters on focus, topic, and givenness. Part 2 covers a range of current issues in the field, including quantification, dislocation, and intonation, while Part 3 is concerned with experimental approaches to information structure, including language processing and acquisition. The final part contains a series of linguistic case studies drawn from a wide variety of the world's language families. This volume will be the standard guide to current work in information structure and a major point of departure for future research.

This book deals with the questions asked about the L2 acquisition process within different research paradigms, examines the results found in each approach, and evaluates the contributions of each to our understanding of L2 acquisition of syntax and to possible implications for L2 instruction.

This book brings together contributions by prominent researchers in the fields of language processing and language acquisition on topics of common interest: how people refer to objects in the world, how people comprehend such referential expressions, and how children acquire the ability to refer and to understand reference.

This book describes the repertoire and uses of referring expressions by French-speaking children and their interlocutors in naturally occurring dialogues at home and at school, in a wide range of communicative situations and activities. Through the lens of an interactionist and dialogical perspective, it highlights the interaction between the formal aspects of the acquisition of grammatical morphemes, the discourse-pragmatic dimension, and socio-discursive, interactional and dialogical factors. Drawing on this multidimensional theoretical and methodological framework, the first part of the book deals with the relation between reference and grammar, while the second part is devoted to the role of the communicative experience. Progressively, a set of arguments is brought out in favor of a dialogical and interactionist account of children’s referential development. This theoretical stance is further discussed in relation to other approaches of reference acquisition. Thus, this volume provides researchers and students with new perspectives and methods for the study of referring expressions in children.
