The current study reports results from a visual masked priming experiment focusing on different types of derived word forms (specifically prefixed vs. suffixed) in first and second language speakers of German.

Our focus is on Specific Language Impairment (SLI) in bilingual (Turkish-German) children. We specifically investigated a range of phenomena related to the so-called CP (Complementizer Phrase) in German, the hierarchically highest layer of syntactic clause structure, which has been argued to be particularly affected in children with SLI. Spontaneous speech data were examined from bilingual children with SLI in comparison to two comparison groups: (i) typically-developing bilingual children, (ii) monolingual children with SLI. We found that despite persistent difficulty with subject-verb agreement, the two groups of children with SLI did not show any impairment of the CP-domain. We conclude that while subject-verb agreement is a suitable linguistic marker of SLI in German-speaking children, for both monolingual and bilingual ones, 'vulnerability of the CP-domain' is not.

The paper gives an overview on findings on early language acquisition in bilingual infants during the first two years of life and compares these findings to current knowledge on early language acquisition in monolingual infants. Given the state of the research, the overview focuses on research on phonological and early lexical development in the first two years of life. We will show that the developmental trajectory of early language acquisition in these areas is very similar in mono- and bilingual infants suggesting that these early steps into language are guided by mechanisms that are rather robust against the differences in the conditions of language exposure that mono- and bilingual infants typically experience.

The main claim of the dissertation is twofold. First, we argue that syllabic organization exerts multiple effects on the spatio-temporal properties of the segments that partake in that organization. That is, there is no unique or privileged exponent of syllabic organization. Rather, syllabic organization is expressed in a pleiotropy of phonetic indices. Second, we claim that a better understanding of the relation between qualitative phonological organization and continuous phonetics is reached when one considers how the string of segments (over which the nature of the phonological organization is assessed) responds to perturbations (scaling of phonetic variables) of localized properties (such as durations) within that string. Specifically, variation in phonetic variables and more specifically prosodic variation is a crucial key to understanding the nature of the link between (phonological) syllabic organization and the phonetic spatio-temporal manifestation of that organization. The effects of prosodic variation on segmental properties and on the overlap between the segments, we argue, offer the right pathway to discover patterns related to syllabic organization. In our approach, to uncover evidence for global organization, the sequence of segments partaking in that organization as well as properties of these segments or their relations with one another must be somehow locally varied. The consequences of such variation on the rest of the sequence can then be used to unveil the span of organization. When local perturbations to segments or relations between adjacent segments have effects that ripple through the rest of the sequence, this is evidence that organization is global. If instead local perturbations stay local with no consequences for the rest of the whole, this indicates that organization is local. N2 - Die vorliegende Dissertation befasst sich mit dem Verhältnis zwischen qualitativer Phonologie im Sinne silbischer Struktur und kontinuierlicher Phonetik im Sinne raum- und zeitbezogener Eigenschaften artikulatorischer Bewegungen, welche ebendiese Struktur ausdrücken. Die Dissertation stellt zwei Hauptthesen auf: Erstens behaupten wir, dass silbische Struktur verschiedene Auswirkungen auf die räumlichen und zeitlichen Eigenschaften der beteiligten Segmente hat. Das heißt, dass es keinen einzelnen ausgezeichneten Indikator für die silbische Struktur gibt, vielmehr muss diese durch mehrere verschiedene phonetischen Indexe beschrieben werden. Zweitens behaupten wir, dass man ein besseres Verständnis über den Zusammenhang von qualitativer phonologischer Struktur und kontinuierlicher Phonetik erhält, wenn man berücksichtigt, wie Abfolgen von Segmenten, welche die phonologische Struktur bestimmen, auf Perturbationen von lokalen phonetischen Eigenschaften reagieren. Die Variabilität phonetischer und insbesondere prosodischer Parameter spielt hierbei eine wesentliche Rolle. Wir behaupten, dass die Effekte prosodischer Variation der Eigenschaften einzelner Segmente und deren Überlappung einen geeigneten Weg zur Aufklärung silbisch-struktureller Muster aufzeigen. Wenn man Hinweise auf eine globale silbische Struktur herausarbeiten möchte, müssen folglich sowohl die Abfolge als auch die lokalen Eigenschaften der beteiligten Segmente variiert werden. Auswirkungen der Variationen können dann Auskunft über der Art und Gestalt der silbischen Struktur geben. Wenn lokale Perturbationen von Segmenten oder von Relationen zwischen benachbarten Segmenten die restliche Sequenz beeinflussen, ist dies als Hinweis auf eine globale Organisation zu bewerten. Wenn lokale Perturbationen hingegen lokal verbleiben ohne die restliche Sequenz zu beeinflussen, ist dies als Hinweis auf eine lokale Organisation zu bewerten.

This distribution has led to conflicting results in studies that investigated pronoun resolution in agrammatic indviduals. In the investigation of pronominal resolution, the linguistic phenomenon of "resumption" is understudied in agrammatism. The construction of pronominal resolution in Akan presents the opportunity to thoroughly examine resumption. Aims: To start, the present study examines the production of (pronominal) resumption in Akan focus constructions (who-questions and focused declaratives). Second, we explore the effect of grammatical tone on the processing of pronominal (resumption) since Akan is a tonal language. Methods & Procedures: First, we tested the ability to distinguish linguistic and non-linguistic tone in Akan agrammatic speakers. Then, we administered an elicitation task to five Akan agrammatic individuals, controlling for the structural variations in the realization of resumption: focused who-questions and declaratives with (i) only a resumptive pronoun, (ii) only a clause determiner, (iii) a resumptive pronoun and a clause determiner co-occurring, and (iv) neither a resumptive pronoun nor a clause determiner. Outcomes & Results: Tone discrimination .both for pitch and for lexical tone was unimpaired. The production task demonstrated that the production of resumptive pronouns and clause determiners was intact. However, the production of declarative sentences in derived word order was impaired; wh-object questions were relatively well-preserved. Conclusions: We argue that the problems with sentence production are highly selective: linguistic tones and resumption are intact but word order is impaired in non-canonical declarative sentences.

Another strand of work in L&V aims at pragmatically informative rather than "correct" object descriptions, e.g. in reference games. We combine these lines of research and model zero-shot reference games, where a speaker needs to successfully refer to a novel object in an image. Inspired by models of "rational speech acts", we extend a neural generator to become a pragmatic speaker reasoning about uncertain object categories. As a result of this reasoning, the generator produces fewer nouns and names of distractor categories as compared to a literal speaker. We show that this conversational strategy for dealing with novel objects often improves communicative success, in terms of resolution accuracy of an automatic listener.
