The First Annual Clinical Aphasiology Conference (CAC) was convened in Albuquerque in 1971. It was attended by a small group of primarily practicing clinicians dedicated to meeting the human service needs of their clients, while recognizing the importance of contributing to the collective knowledge base of their discipline by providing empirical evidence supporting the links between their clinical interventions and outcomes. Thirteen years later Barlow, Hays, and Nelson (1984) would describe, in their now seminal publication The Scientist Practitioner, an integrated model of applied behavioral research, its strategies and methods, and the role of the practitioner in the acquisition of knowledge directed toward improving clinical procedures and outcomes. By this time, 13 Volumes of CAC publications had already been published and comprised the single largest source of applied clinical data addressing the nature of aphasia and its clinical management. These documents represented the product of the scientist-practitioner model in action prior to its formalization by Barlow et al., and provide a rich source of evidence supporting the efficacy of aphasia rehabilitation. Unfortunately, these and subsequent CAC publications remain unavailable to the larger clinical and scientific community due to their limited distribution. Much has changed in the ensuing years. Indeed, many of the healthcare delivery systems in which aphasia rehabilitation is now practiced in 2002 severely restrict the frequency and duration of clinical services. Increasingly, practitioners are required to be more accountable for their clinical outcomes, and to measure behavioral change in units that represent meaningful differences to consumers. Now more than ever, it is critical that the scientist-practitioner model be promoted in order to better serve individuals with aphasia, and to further advance the collective knowledge and evidence base of the discipline. Now more than ever, the available evidence needs to be disseminated as broadly as possible. These goals are in keeping with the mission of CAC as envisioned by its founding members and remain the focused commitment of its many participants, steering committee and publication board. In keeping with these goals, the papers that appear in this special edition of Aphasiology were selected based upon their theoretical importance, clinical relevance, and scientific merit, from among the many platform and poster presentations comprising the 31st Annual Clinical Aphasiology Conference held in Santa Fe, New Mexico in 2001. Each paper was peer-reviewed by the Editorial Consultants and Associate Editors acknowledged herein consistent with the standards of Aphasiology and the rigours of merit review that represent this indexed, archival journal that is accessible to clinicians and scientists all over the world.

This book presents a collection of cutting edge work from leading researchers and clinicians around the world on a range of topics within Clinical Aphasiology. However, more than this, the volume is also a tribute to Chris Code, one of the foremost scholars in the field. Professor Code has made a galvanizing impact on the field: as a savant, a motivator and an impresario of trends which have resulted in several significant developments in the field. In the first chapter of this book the editors outline the considerable contributions Chris Code has made to the area. The remaining contents have been divided into three main approaches to the study of aphasia, reflecting Professor Code's own interests. First are the contributions that fall under the heading of Conceptual Considerations. These are mainly interdisciplinary in nature, spanning linguistics, phonetics, psychology and neurology, as well as social aspects of communication disorders. The second section of the book deals with Research Considerations, with chapters ranging from how the study of disrupted communication can inform models of normal language processing, through tone production and processing in speakers with aphasia, to anomia and progressive multifocal leukoencephalopathy. Each of these chapters explores different aspects of research methodology, including quantitative and qualitative research. The final section of the collection deals with Clinical Considerations; the chapters here cover counselling, computerized training, cultural and linguistic diversity in aphasia, right hemisphere disorders, and communication problems in the dementias. Clinical Aphasiology will be an invaluable tool for both students and practitioners in speech and language pathology, psychology, neurology, and related fields.

Frederic L. Darley was the consummate clinical scientist. One cannot peruse the literature on neurogenic communication disorders without constantly encountering his name, his work, his influence. His work was monumental. The contributors of the seven papers in this issue of Aphasiology have long and impressive track records as researchers and clinicians. Their papers are important because not only do they reflect how Darley's work has influenced diagnostic and patient management decisions, but in some cases the contributors take issue with and/or expand on his work. This ability to question existing evidence was a trait that Fred Darley instilled in his students. Equally important is that each paper tells us something about him as a person, as a mentor who shaped careers, and about the love and respect his students and colleagues had for him.

First published in 2011. Routledge is an imprint of Taylor & Francis, an informa company.

A comprehensive introduction to the emerging fields of neurolinguistics and linguistic aphasiology stresses concepts from the contributing disciplines of neurology, linguistics, psychology and speech.

This work brings together a selection of Clinical Forum features from the journal "Aphasiology". The fora are designed to cover issues in clinical aphasiology which are central, topical and controversial. Each forum concerns a main article and a number of commentaries.

This special issue of Aphasiology represents the papers accepted for publication which were among those presented at the 34th Clinical Aphasiology Conference, held in Park City Utah in 2004. They have been peer-reviewed and selected by a distinguished group of ad-hoc editorial consultants from among the considerably larger number of papers and posters presented at the meeting itself.

The papers that appear in this special edition of Aphasiology were selected based upon their theoretical importance, clinical relevance, and scientific merit, from among the many platform and poster presentations comprising the 32nd Annual Clinical Aphasiology Conference held in Ridgedale, Missouri in June of 2002. Each paper was peer-reviewed by the Editorial Consultants and Associate Editors acknowledged herein consistent with the standards of Aphasiology and the rigours of merit review that represent this indexed, archival journal.

Papers in this volume were drawn from presentations at the 29th Annual Clinical Aphasiology Conference in Key West, Florida, USA, in June, 1999. A Wide range of topics is included in the issue including a series of papers that address qualitative research methods in aphasia. The broad range of clinical issues published in this special edition include investigations of individuals with aphasia, right brain damage, traumatic brain injury, and apraxia of speech. The contents of the journal will be of interest to experienced researchers and clinicians as well as students in training.

Aphasia is the most common acquired language disorder in adults, resulting from brain damage, usually stroke. This book firstly explains how aphasia research and clinical practice remain heavily influenced by rule-based, generative theory, and summarizes key shortcomings with this approach. Crucially, it demonstrates how an alternative — the constructivist, usage-based approach — can provide a more plausible theoretical perspective for characterizing language in aphasia. After detailing rigorous transcription and segmentation methods, it presents constructivist, usage-based analyses of spontaneous speech from people with various aphasia ‘types’, challenging a clear-cut distinction between lexis and grammar, emphasizing the need to consider whole-form storage and frequency effects beyond single words, and indicating that individuals fall along a continuum of spoken language capability rather than differing categorically by aphasia ‘type’. It provides original insight into aphasia — with wide-reaching implications for clinical practice —, while equally highlighting how the study of aphasia is important for the development of Cognitive Linguistics.
