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.}, language = {en} } @article{Felser2019, author = {Felser, Claudia}, title = {Do processing resource limitations shape heritage language grammars?}, series = {Bilingualism : language and cognition}, volume = {23}, journal = {Bilingualism : language and cognition}, number = {1}, publisher = {Cambridge University Press}, address = {New York}, issn = {1366-7289}, doi = {10.1017/S1366728919000397}, pages = {23 -- 24}, year = {2019}, language = {en} } @phdthesis{Sotiropoulou2019, author = {Sotiropoulou, Stavroula}, title = {Pleiotropy of phonetic indices in the expression of syllabic organization}, doi = {10.25932/publishup-54639}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-546399}, school = {Universit{\"a}t Potsdam}, pages = {xv, 184}, year = {2019}, abstract = {This dissertation is concerned with the relation between qualitative phonological organization in the form of syllabic structure and continuous phonetics, that is, the spatial and temporal dimensions of vocal tract action that express syllabic structure. 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.}, language = {en} } @article{LarteyTsiwahAmponsahetal.2019, author = {Lartey, Nathaniel and Tsiwah, Frank and Amponsah, Clement and Martinez-Ferreiro, Silvia and Bastiaanse, Roelien}, title = {Resumption in the production of focused constructions in Akan speakers with agrammatism}, series = {Aphasiology}, volume = {34}, journal = {Aphasiology}, number = {3}, publisher = {Routledge}, address = {London}, doi = {10.1080/02687038.2019.1686746}, pages = {343 -- 364}, year = {2019}, abstract = {Background: The distribution of pronouns varies cross-linguistically.

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.

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.
