Summary:

"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 summarises key shortcomings with this approach. Crucially, it demonstrates how an alternative - the constructivist, usage-based approach - can provide a more plausible theoretical perspective for characterising 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, emphasising 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"-- Provided by publisher.
