Language Is A Complex Adaptive System Explorations And Evidence

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.

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."

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.
