Morphological and phonological processes are tightly interrelated in spoken production. During processing, morphological processes must combine the phonological content of individual morphemes to produce a phonological representation that is suitable for driving phonological processing. Further, morpheme assembly frequently causes changes in a…

Purpose: The International Consensus Criteria for the diagnosis of primary progressive aphasia (PPA; Gorno-Tempini et al., 2011) propose apraxia of speech (AOS) as 1 of 2 core features of nonfluent/agrammatic PPA and propose phonological errors or absence of motor speech disorder as features of logopenic PPA. We investigated the sensitivity and…

Phonation is a fundamental feature of human communication. Control of phonation in the context of speech-language disturbances has traditionally been considered a characteristic of lesions to subcortical structures and pathways. Evidence suggests however, that cortical lesions may also implicate phonation. We carried out acoustic and perceptual…

Conduction aphasia is a language disorder characterized by frequent speech errors, impaired verbatim repetition, a deficit in phonological short-term memory, and naming difficulties in the presence of otherwise fluent and grammatical speech output. While traditional models of conduction aphasia have typically implicated white matter pathways,…

Special issue devoted to neurolinguistics and neuropsychology. (VM)

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…
