The ASLAN labex - Advanced studies on language complexity - brings together a unique set of expertise and varied points of view on language. In this volume, we employ three main sections showcasing diverse empirical work to illustrate how language within human interaction is a complex and adaptive system. The first section – epistemological views on complexity – pleads for epistemological plurality, an end to dichotomies, and proposes different ways to connect and translate between frameworks. The second section – complexity, pragmatics and discourse – focuses on discourse practices at different levels of description. Other semiotic systems, in addition to language are mobilized, but also interlocutors’ perception, memory and understanding of culture. The third section – complexity, interaction, and multimodality – employs different disciplinary frameworks to weave between micro, meso, and macro levels of analyses. Our specific contributions include adding elements to and extending the field of application of the models proposed by others through new examples of emergence, interplay of heterogeneous elements, intrinsic diversity, feedback, novelty, self-organization, adaptation, multi-dimensionality, indeterminism, and collective control with distributed emergence. Finally, we argue for a change in vantage point regarding the search for linguistic universals.

The ASLAN labex - Advanced studies on language complexity - brings together a unique set of expertise and varied points of view on language. In this volume, we employ three main sections showcasing diverse empirical work to illustrate how language within human interaction is a complex and adaptive system. The first section — epistemological views on complexity — pleads for epistemological plurality, an end to dichotomies, and proposes different ways to connect and translate between frameworks. The second section — complexity, pragmatics and discourse — focuses on discourse practices at different levels of description. Other semiotic systems, in addition to language are mobilized, but also interlocutors’ perception, memory and understanding of culture.

Current research in grammatical analysis and sociolinguistics points to two core characteristics of language that seem incommensurable at first sight: (1) research on linguistic structure indicates internal organisation and coherence, and the workings and interactions of distinct grammatical systems, but (2) sociolinguistic research suggests that language borders and bound “languages” are counterfactual social constructs that cannot capture the diversity and fluidity of actual language use. This seems to constitute something like a “quantum-linguistic” paradox: language systems aren’t real (they are just ideological constructions), but at the same time, they are a reflection of actual structure. This book shows how this paradox can be resolved through an architecture that allows for grammatical systems without presupposing language borders: this architecture puts communicative situations, rather than languages, at the core of linguistic systematicity, while named languages are captured as optional sociolinguistic indices. The approach builds on insights from “free-range” language, a metaphor for language in settings that are less confined by monoglossic ideologies. The author looks at four different kinds of settings: urban markets, heritage language settings, multiethnic adolescent peer-groups, and digital social media. Central lessons to be learned from such free-range language settings are: (1) communicative situations support linguistic differentiation and can thus be the basis for fluid registers; (2) grammatical systematicity is grounded in communicative situations and does not require bound languages and linguistic borders; (3) named “languages” can emerge as social indices signalling belonging, but this is an optional, not a necessary development.

Research in linguistics, as in most other scientific domains, is usually approached in a modular way – narrowing the domain of inquiry in order to allow for increased depth of study. This is necessary and productive for a topic as wide-ranging and complex as human language. However, precisely because language is a complex system, tied to perception, learning, memory, and social organization, the assumption of modularity can also be an obstacle to understanding language at a deeper level. This book examines the consequences of enforcing non-modularity along two dimensions: the temporal, and the cognitive. Along the temporal dimension, synchronic and diachronic domains are linked by the requirement that sound changes must lead to viable, stable language states. Along the cognitive dimension, sound change and variation are linked to speech perception and production by requiring non-trivial transformations between acoustic and articulatory representations. The methodological focus of this work is on computational modeling. By formalising and implementing theoretical accounts, modeling can expose theoretical gaps and covert assumptions. To do so, it is necessary to formally assess the functional equivalence of specific implementational choices, as well as their mapping to theoretical structures. This book applies this analytic approach to a series of implemented models of sound change. As theoretical inconsistencies are discovered, possible solutions are proposed, incrementally constructing a set of sufficient properties for a working model. Because internal theoretical consistency is enforced, this model corresponds to an explanatorily adequate theory. And because explicit links between modules are required, this is a theory, not only of sound change, but of many aspects of phonological competence. The book highlights two aspects of modeling work that receive relatively little attention: the formal mapping from model to theory, and the scalability of demonstration models. Focusing on these aspects of modeling makes it clear that any theory of sound change in the specific is impossible without a more general theory of language: of the relationship between perception and production, the relationship between phonetics and phonology, the learning of linguistic units, and the nature of underlying representations. Theories of sound change that do not explicitly address these aspects of language are making tacit, untested assumptions about their properties. Addressing so many aspects of language may seem to complicate the linguist's task. However, as this book shows, it actually helps impose boundary conditions of ecological validity that reduce the theoretical search space.

This book presents the current state of the art on Construction Grammar models and usage-based language learning research. It reports on three psycholinguistic experiments conducted with the participation of university-level Italian learners of English, whose second language proficiency corresponds to levels B1 and B2 of the ‘Common European Framework of Reference for Languages’ (CEFR). This empirical research on the role of constructions in the facilitation of language learning contributes to assessing how bilinguals deal with L2 constructions in the light of sentence-sorting, sentence-elicitation, and sentence-completion tasks. Divided into two parts, the book first introduces the main theoretical prerequisites and then reports on the experimental studies. It provides a comprehensive review of the current research in a range of disciplines, including complexity theories, cognitive semantics, construction grammars, usage-based linguistics, and language learning.

This volume provides an up-to-date discussion of a foundational issue that has recently taken centre stage in linguistic typology and which is relevant to the language sciences more generally: To what extent can cross-linguistic generalizations, i.e. statistical universals of linguistic structure, be explained by the diachronic sources of these structures? Everyone agrees that typological distributions are the result of complex histories, as “languages evolve into the variation states to which synchronic universals pertain” (Hawkins 1988). However, an increasingly popular line of argumentation holds that many, perhaps most, typological regularities are long-term reflections of their diachronic sources, rather than being ‘target-driven’ by overarching functional-adaptive motivations. On this view, recurrent pathways of reanalysis and grammaticalization can lead to uniform synchronic results, obviating the need to postulate global forces like ambiguity avoidance, processing efficiency or iconicity, especially if there is no evidence for such motivations in the genesis of the respective constructions. On the other hand, the recent typological literature is equally ripe with talk of "complex adaptive systems", "attractor states" and "cross-linguistic convergence". One may wonder, therefore, how much room is left for traditional functional-adaptive forces and how exactly they influence the diachronic trajectories that shape universal distributions. The papers in the present volume are intended to provide an accessible introduction to this debate. Covering theoretical, methodological and empirical facets of the issue at hand, they represent current ways of thinking about the role of diachronic sources in explaining grammatical universals, articulated by seasoned and budding linguists alike.

Explores a new approach to studying language as a complex adaptive system, illustrating its commonalities across many areas of language research Brings together a team of leading researchers in linguistics, psychology, and complex systems to discuss the groundbreaking significance of this perspective for their work Illustrates its application across a variety of subfields, including languages usage, language evolution, language structure, and first and second language acquisition "What a breath of fresh air! As interesting a collection of papers as you are likely to find on the evolution, learning, and use of language from the point of view of both cognitive underpinnings and communicative functions."

Human Spoken Interaction as a Complex Adaptive System explains how human spoken communication functions, combining two separate complex adaptive systems: the universal 'interaction engine' and language(s), which now number around 7,000. Siegel and Seedhouse offer a comprehensive overview of how the components and processes of the interaction engine work together to enable us to understand each other, whatever the language. Through combining Complexity Science and Conversation Analysis, this book explains how to simultaneously analyse spoken interaction on micro and macro scales. Detailed analyses of L2 learners reveal them to be simultaneously expert in using the interaction engine and inexpert in using the specific language. The study shows that the basic characteristics of the interaction engine are the same as for other life-related complex systems and that it is possible to access the perspectives of participants inside this complex adaptive system as it is evolving.

This book offers a model of language that can be characterized as functionalist, usage-based, dynamic, and complex-adaptive. Schmid argues that linguistic structure is not stable, but continually refreshed by usage, conventionalization, and entrenchment. This wide-ranging volume will be of interest to linguists from a wide range of fields.

In what ways are language, cognition and perception interrelated? Do they influence each other? This book casts a fresh light on these questions by putting individual speakers’ cognitive contexts, i.e. their usage-preferences and entrenched patterns of linguistic knowledge, into the focus of investigation. It presents findings from original experimental research on spatial language use which indicate that these individual-specific factors indeed play a central role in determining whether or not differences in the current and/or habitual linguistic behaviour of speakers of German and English are systematically correlated with differences in non-linguistic behaviour (visual attention allocation to and memory for spatial referent scenes). These findings form the basis of a new, speaker-focused usage-based model of linguistic relativity, which defines language-perception/cognition effects as a phenomenon which primarily occurs within individual speakers rather than between speakers or speech communities.
