Purpose: Spontaneous speech tasks are critically important for characterizing spoken language production deficits in aphasia and for assessing the impact of therapy. The utility of such tasks arises from the complex interaction of linguistic demands (word retrieval, sentence formulation, articulation). However, this complexity also makes…

Compounds are words that are made up of at least two other words (lexemes), featuring lexical and syntactic characteristics and thus particularly interesting for the study of language processing. Most studies of compounds and language processing have been based on data from experimental single word production and comprehension tasks. To enhance…

Current accounts of spoken language assume the existence of a lexicon where wordforms are stored and interact during spoken language perception, understanding and production. Despite the theoretical importance of the wordform lexicon, the exact localization and function of the lexicon in the broader context of language use is not well understood.…

This article provides a detailed assessment of patient HT with a history of progressive language deterioration of approximately 6 years presenting now as a fluent jargon aphasic with severe impairment of both speech production and comprehension. Neuropsychological testing of non-verbal cognitive functions showed no impairment, leading to the…

Few studies have directly compared the clinical and anatomical characteristics of patients with progressive aphasia to those of patients with aphasia caused by stroke. In the current study we examined fluent forms of aphasia in these two groups, specifically semantic dementia (SD) and persisting Wernicke's aphasia (WA) due to stroke. We compared…

Bilateral vascular thalamic lesions are rare. Although a variety of neurobehavioral manifestations have been described, the literature is less documented with regard to accompanying linguistic disturbances. This article presents an in-depth neurolinguistic analysis of the language symptoms of a patient who incurred bilateral paramedian ischemic…

This book presents a study of speech, language, and behavior as related in the field of psycholinguistics. It confines itself to a limited number of topics which are treated in some depth. The first part of the book deals with theoretical foundations--discussing speech and language in terms of role, nature, semantic dimension, and pragmatic…

THE RELATIONSHIP BETWEEN BIOLOGY AND LANGUAGE IS EXPLORED IN THIS VOLUME. THE AUTHOR BELIEVES THAT "LANGUAGE IS THE MANIFESTATION OF SPECIES-SPECIFIC COGNITIVE PROPENSITIES. IT IS THE CONSEQUENCE OF THE BIOLOGICAL PECULIARITIES THAT MAKE A HUMAN TYPE OF COGNITION POSSIBLE." IN ATTEMPTING TO "REINSTATE THE CONCEPT OF THE BIOLOGICAL BASIS OF…
