The workshop Production-Comprehension Asymmetries in Child Language held in Osnabrück in 2009 is the starting point for this book. The workshop developed from the observation that children's production skills appear to precede their comprehension skills in a number of phenomena, e.g. pronouns or negation. The volume provides cross-linguistic evidence for such asymmetric development and investigates grammatical and methodical explanations of the observed asymmetries.

This book asserts that language is a signaling system rather than a code, based in part on such research as the finding that 5-year-old English and Dutch children use pronouns correctly in their own utterances, but often fail to interpret these forms correctly when used by someone else. Emphasizing the unique and sometimes competing demands of listener and speaker, the author examines resulting asymmetries between production and comprehension. The text offers examples of the interpretation of word order and pronouns by listeners, and word order freezing and referential choice by speakers. It is explored why the usual symmetry breaks down in children but also sometimes in adults. Gathering contemporary insights from theoretical linguistic research, psycholinguistic studies and computational modeling, Asymmetries between Language Production and Comprehension presents a unified explanation of this phenomenon. “Through a lucid, comprehensive review of acquisition studies on reference-related phenomena, Petra Hendriks builds a striking case for the pervasiveness of asymmetries in comprehension/production. In her view, listeners systematically misunderstand what they hear, and speakers systematically fail to prevent such misunderstandings. She argues that linguistic theory should take stock of current psycholinguistic and developmental evidence on optionality and ambiguity, and recognize language as a signaling system. The arguments are compelling yet controversial: grammar does not specify a one-to-one correspondence between form and meaning; and the demands of the mapping task differ for listeners and speakers. Her proposal is formalized within optimality theory, but researchers working outside this framework will still find it of great interest. In the language-as-code vs. language-as-signal debate, Hendriks puts the ball firmly in the other court.” Ana Pérez-Leroux, University of Toronto, Canada

How do production and comprehension processes interact in the bilingual brain during language interaction? Most experimental and theoretical research in psycholinguistics to date has focused on investigating the mechanisms that underlie language production and language comprehension separately. Only recently have researchers started emphasizing the importance of reconciling the two modalities into a unified account through the investigation of possible connections between the two systems. Authored by key researchers in psycholinguistics, neuroscience, and language development, this volume encompasses state of the art research on the relation between production and comprehension processes in bilingual children and adults. Articles highlight the most recent methodological approaches, as well as a variety of language pairs and linguistic structures. Indispensable for students and researchers working in the areas of language acquisition and processing, neurolinguistics, and experimental linguistics, this volume will also appeal to educators and clinicians focusing on language development and processing in multilingual children and adults. Originally published as special issue of Linguistic Approaches to Bilingualism 9:4/5 (2019).

Over the past three decades studies investigating heritage speaker (HS) linguistic competencies have shown, time and again that, despite being L1 or 2L1 native speakers of their home language(s), HS outcomes display variation across a wide spectrum of differences as compared to each other, other types of bilinguals as well as their monolingual peers. Studies have traditionally used—mostly behavioral—methodologies rooted in adjacent established fields (e.g., L1 acquisition, adult L2 acquisition) offering, in addition to documenting and describing HS performance, important insights for linguistic theory and challenges related to (home/minority) language maintenance, contact, policy and more. A birds-eye view makes it clear that the methodologies one uses to tap into HSs’ linguistic knowledge areas, if not more, are important than the phenomena under investigation, especially in light of how their unique experiences with their heritage and other languages are present across a continuum.

Previous studies on the acquisition of verb inflection in normally developing children have revealed an astonishing pattern: children use correctly inflected verbs in their own speech but fail to make use of verb inflections when comprehending sentences uttered by others. Thus, a three-year old might well be able to say something like ‘The cat sleeps on the bed’, but fails to understand that the same sentence, when uttered by another person, refers to only one sleeping cat but not more than one. The previous studies that have examined children's comprehension of verb inflections have employed a variant of a picture selection task in which the child was asked to explicitly indicate (via pointing) what semantic meaning she had inferred from the test sentence. Recent research on other linguistic structures, such as pronouns or focus particles, has indicated that earlier comprehension abilities can be found when methods are used that do not require an explicit reaction, like preferential looking tasks. This dissertation aimed to examine whether children are truly not able to understand the connection the the verb form and the meaning of the sentence subject until the age of five years or whether earlier comprehension can be found when a different measure, preferential looking, is used. Additionally, children's processing of subject-verb agreement violations was examined. The three experiments of this thesis that examined children's comprehension of verb inflections revealed the following: German-speaking three- to four-year old children looked more to a picture showing one actor when hearing a sentence with a singular inflected verb but only when their eye gaze was tracked and they did not have to perform a picture selection task. When they were asked to point to the matching picture, they performed at chance-level. This pattern indicates asymmetries in children's language performance even within the receptive modality. The fourth experiment examined sensitivity to subject-verb agreement violations and did not reveal evidence for sensitivity toward agreement violations in three- and four-year old children, but only found that children's looking patterns were influenced by the grammatical violations at the age of five. The results from these experiments are discussed in relation to the existence of a production-comprehension asymmetry in the use of verb inflections and children's underlying grammatical knowledge.

This edited collection contains 34 papers originally presented at the Generative Approaches to Language Acquisition (GALA) conference in 2013, held in Oldenburg, Germany. It represents theoretically guided, high quality work, and provides impressive insights into state-of-the-art research in the fields of first and second language acquisition and developmental impairments. The studies brought together here cover a wide variety of different (mainly European) languages, focusing on the areas of phonology, morpho-syntax, semantics, pragmatics, and their interfaces. Since their first publication, the proceedings of GALA have become an invaluable reference for cutting-edge research in First and Second Language Acquisition and its impairments – and this volume continues that tradition.

This book presents a current state-of-affairs regarding the study of cross-linguistic influence in bilingualism. Taking Hulk and Müller’s (2000) and Müller and Hulk’s (2001) hypotheses on cross-linguistic influence as a starting point, the book exemplifies the shift from the original focus on syntax proper to interfaces and discourse phenomena in the study of bilingualism. It also reflects the enormous increase in different language combinations (including dialects) being investigated, and the use of new methodologies. Moreover, the volume illustrates the growing interdisciplinarity of cross-linguistic influence research, considering extra-linguistic cognitive and social factors besides linguistics. It demonstrates that the time is ripe for a more integrated approach from different disciplines such as theoretical linguistics, psycholinguistics and sociolinguistics to obtain a better understanding of bilingual child acquisition. As such, it is of interest to (psycho/socio)linguists, psychologists and education specialists who study or want to learn about (child) bilingualism.

This volume gathers fifty papers from the conference Generative Approaches to Language Acquisition, GALA 2007, celebrated in Barcelona between the 6th and 8th of September, 2007. It covers the areas of syntax and phonology of child language from the theoretical perspective of generative grammar – the theoretical outlook which first placed language acquisition at the centre of linguistic inquiry.

This book investigates the morphosyntactic, semantic, and pragmatic properties of language, and the interactions between them, from the perspective of Optimality Theory. It integrates optimization processes into the formal and functional study of grammar, interpreting optimization as the result of conflicting, violable ranked constraints. Unlike previous work on the topic, this book also takes into account the question of directionality of grammar. A model of grammar in which optimization processes interact bidirectionally allows both language generation-the process of selecting the optimal form of a given meaning-and language interpretation-the process of optimal interpretation of a given form-to be taken into account. Chapters in this volume explore the consequences of both symmetric (unidirectional) and asymmetric (bidirectional) versions of Optimality Theory, investigating the syntax-semantics interface, first language acquisition, and sequential bilingual grammars. The volume presents cutting edge research in Optimality-Theoretic syntax and semantics, as well as demonstrating how optimization processes as modelled in this formalism serve as a viable approach for linguists and scholars in related fields.
