This highly interdisciplinary project presents new results and the state of the art of knowledge in the psychology and neurophysiology of language, reading and dyslexia. It concentrates on basic cognitive functions of understanding and producing language and disorders within its spoken and written execution. The book grew out of the Basic Mechanisms of Language and Language Disorders conference (Leipzig, Sept. 1999).

The concept of semantic roles has been central to linguistic theory for many decades. More specifically, the assumption of such representations as mediators in the correspondence between a linguistic form and its associated meaning has helped to address a number of critical issues related to grammatical phenomena. Furthermore, in addition to featuring in all major theories of grammar, semantic (or 'thematic') roles have been referred to extensively within a wide range of other linguistic subdisciplines, including language typology and psycho-/neurolinguistics. This volume brings together insights from these different perspectives and thereby, for the first time, seeks to build upon the obvious potential for cross-fertilisation between hitherto autonomous approaches to a common theme. To this end, a view on semantic roles is adopted that goes beyond the mere assumption of generalised roles, but also focuses on their hierarchical organisation. The book is thus centred around the interdisciplinary examination of how these hierarchical dependencies subserve argument linking - both in terms of linguistic theory and with respect to real-time language processing - and how they interact with other information types in this process. Furthermore, the contributions examine the interaction between the role hierarchy and the conceptual content of (generalised) semantic roles and investigate their cross-linguistic applicability and psychological reality, as well as their explanatory potential in accounting for phenomena in the domain of language disorders. In bridging the gap between different disciplines, the book provides a valuable overview of current thought on semantic roles and argument linking, and may further serve as a point of departure for future interdisciplinary research in this area. As such, it will be of interest to scientists and advanced students in all domains of linguistics and cognitive science.

The second edition of the book on language comprehension in honor of Pim Levelt's sixtieth birthday has been released before he turns sixty-one. Some things move faster than the years of age. This seems to be especially true for advances in science. Therefore, the present edition entails changes in some of the chapters and incorporates an update of the current literature. I would like to thank all contributors for their cooperation in making a second edition possible such a short time after the completion of the first one. Angela D. Friederici Leipzig, November 23, 1998. Preface to the first edition Language comprehension and production is a uniquely human capability. We know little about the evolution of language as a human trait, possibly because our direct ancestors lived several million years ago. This fact certainly impedes the desirable advances in the biological basis of any theory of language evolution. Our knowledge about language as an existing species-specific biological sys tem, however, has advanced dramatically over the last two decades. New experi mental techniques have allowed the investigation of language and language use within the methodological framework of the natural sciences. The present book provides an overview of the experimental research in the area of language com prehension in particular."

Dieses Buch behandelt jene kognitiven Strukturen und Prozesse, die der menschlichen Sprachverarbeitung zugrundeliegen. Das hier vorgestellte Modell geht von zwei parallel arbeitenden Subsystemen im Sprachverarbeitungsprozess aus:

A comprehensive account of the neurobiological basis of language, arguing that species-specific brain differences may be at the root of the human capacity for language. Language makes us human. It is an intrinsic part of us, although we seldom think about it. Language is also an extremely complex entity with subcomponents responsible for its phonological, syntactic, and semantic aspects. In this landmark work, Angela Friederici offers a comprehensive account of these subcomponents and how they are integrated. Tracing the neurobiological basis of language across brain regions in humans and other primate species, she argues that species-specific brain differences may be at the root of the human capacity for language. Friederici shows which brain regions support the different language processes and, more important, how these brain regions are connected structurally and functionally to make language processes that take place in milliseconds possible. She finds that one particular brain structure (a white matter dorsal tract), connecting syntax-relevant brain regions, is present only in the mature human brain and only weakly present in other primate brains. Is this the "missing link" that explains humans' capacity for language? Friederici describes the basic language functions and their brain basis; the language networks connecting different language-related brain regions; the brain basis of language acquisition during early childhood and when learning a second language, proposing a neurocognitive model of the ontogeny of language; and the evolution of language and underlying neural constraints. She finds that it is the information exchange between the relevant brain regions, supported by the white matter tract, that is the crucial factor in both language development and evolution.
