This volume features the complete text of the material presented at the Twentieth Annual Conference of the Cognitive Science Society. As in previous years, the symposium included an interesting mixture of papers on many topics from researchers with diverse backgrounds and different goals, presenting a multifaceted view of cognitive science. This volume contains papers, posters, and summaries of symposia presented at the leading conference that brings cognitive scientists together to discuss issues of theoretical and applied concern. Submitted presentations are represented in these proceedings as "long papers" (those presented as spoken presentations and "full posters" at the conference) and "short papers" (those presented as "abstract posters" by members of the Cognitive Science Society).

The book aims to serve as a theoretical framework for the socio-cognitive approach (SCA) that is an alternative to the two main lines of pragmatics research: linguistic-philosophical pragmatics and sociocultural-interactional pragmatics. SCA broadens the scope of the field with an intent to incorporate not only L1 communication but also intercultural communication, and communication in a second language. The author integrates the pragmatic view of cooperation and the cognitive view of egocentrism and emphasizes that both cooperation and egocentrism are manifested in all phases of communication, albeit to varying extents. SCA places equal importance on the social and cognitive individual factors in pragmatics. The author claims that while (social) cooperation is an intention-directed practice that is governed by relevance, (individual) egocentrism is an attention-oriented trait dominated by salience. The book serves as a theoretical guide for researchers and students who would like to understand how we need to change first language-based theories to make sense of what happens not only in L1 but also in intercultural and multi-lingual interactions.

Historically, the social aspects of language use have been considered the domain of social psychology, while the underlying psycholinguistic mechanisms have been the purview of cognitive psychology. Recently, it has become increasingly clear that these two dimensions are highly interrelated: cognitive mechanisms underlying speech production and comprehension interact with social psychological factors, such as beliefs about one's interlocutors and politeness norms, and with the dynamics of the conversation itself, to produce shared meaning. This realization has led to an exciting body of research integrating the social and cognitive dimensions which has greatly increased our understanding of human language use. Each chapter in this volume demonstrates how the theoretical approaches and research methods of social and cognitive psychology can be successfully interwoven to provide insight into one or more fundamental questions about the process of interpersonal communication. The topics under investigation include the nature and role of speaker intentions in the communicative process, the production and comprehension of indirect speech and figurative language, perspective-taking and conversational collaboration, and the relationships between language, cognition, culture, and social interaction. The book will be of interest to all those who study interpersonal language use: social and cognitive psychologists, theoretical and applied linguists, and communication researchers.

Cognitive Radio Communications and Networks gives comprehensive and balanced coverage of the principles of cognitive radio communications, cognitive networks, and details of their implementation, including the latest developments in the standards and spectrum policy. Case studies, end-of-chapter questions, and descriptions of various platforms and test beds, together with sample code, give hands-on knowledge of how cognitive radio systems can be implemented in practice. Extensive treatment is given to several standards, including IEEE 802.22 for TV White Spaces and IEEE SCC41 Written by leading people in the field, both at universities and major industrial research laboratories, this tutorial text gives communications engineers, R&D engineers, researchers, undergraduate and post graduate students a complete reference on the application of wireless communications and network theory for the design and implementation of cognitive radio systems and networks - Each chapter is written by internationally renowned experts, giving complete and balanced treatment of the fundamentals of both cognitive radio communications and cognitive networks, together with implementation details - Extensive treatment of the latest standards and spectrum policy developments enables the development of compliant cognitive systems - Strong practical orientation – through case studies and descriptions of cognitive radio platforms and testbeds – shows how real world cognitive radio systems and network architectures have been built Alexander M.

This book addresses the contemporary disillusion with truth, manifest in sceptical relativism. Contending that all contemporary theories of truth are too narrow, it argues for a novel conception of truth, by showing how error is implicated in the actions of all living things; and by analyzing uses of 'true' in non-linguistic contexts.

The Emergence of Symbols: Cognition and Communication in Infancy provides information pertinent to the nature and origin of symbols, the interdependence of language and thought, and the parallels between phylogeny and ontogeny. This book clarifies some of the conceptual and methodological issues involved in the search for prerequisites to language. Organized into seven chapters, this book begins with an overview of the distinction between homology and analogy in the study of linguistic and nonlinguistic developments. This text then explains the conceptual and operational definitions for such controversial terms as intention, convention, and symbolic behavior. Other chapters consider the limits and advantages of the correlational method as applied in the research. This book discusses as well the structure and content of early symbol use, both in language and in play. The final chapter examines the processes that underlie imitation and tool use, as they contribute to the child's analysis of his culture. This book is a valuable resource for neural biologists, psychologists, and social scientists.
