The study of homophones--words with different meanings that sound the same--has great potential to inform models of language production. Of particular relevance is a phenomenon termed "frequency" inheritance, where a low-frequency word (e.g., "deer") is produced more fluently than would be expected based on its frequency…

The current study aimed to use electromagnetic articulography (EMA) to investigate the effect of increasing word length on lingual kinematics in acquired apraxia of speech (AOS). Tongue-tip and tongue-back movement was recorded for five speakers with AOS and a concomitant aphasia (mean age = 53.6 years; SD = 12.60) during target consonant…

This study investigates neighbourhood density effects on lexical decision performance (both accuracy and response times) of aphasic patients. Given earlier results on lexical activation and deactivation in Broca's and Wernicke's aphasia, the prediction was that smaller neighbourhood density effects would be found for Broca's aphasic patients,…

Lexical access in language production, and particularly pathologies of lexical access, are often investigated by examining errors in picture naming and word repetition. In this article, we test a computational approach to lexical access, the two-step interactive model, by examining whether the model can quantitatively predict the repetition-error…

Reports on a study in which subjects heard the beginnings of spoken words, followed by increasingly larger segments of word-onset information until the words could be correctly identified. Results are discussed in terms of word-initial phonology as a trigger for response activation. (34 references) (Author/OD)

Erroneous responses of some aphasic patients resemble the sorts of words a normal person produces when searching for a target word that is on the tip of the tongue. With aphasics, words are well-formed phonologically and the number of syllables and stress patterns are correct also. (SC)

Special issue devoted to neurolinguistics and neuropsychology. (VM)

Major findings are reported of a longitudinal, naturalistic study of grammatical morpheme development in an aphasic child from 5;5 to 6;1. The majority of the morphemes were not acquired in the same order nor at the same mean length of utterance (MLU) levels reported for normal children. As an alternative to the normal acquisition model, based on…

Notes that prior assumptions that writing requires phonological mediation has been questioned due to the observation that on tasks requiring the production of spoken and written responses on the same naming attempt, some aphasic subjects produce different words. The data suggest that phonological and orthographic word forms can interact. (53…

In this book, current work and issues in psycholinguistics are reviewed by 19 noted authorities in the fields of psychology, linguistics, education, psychiatry, and medicine. The seven sections of the book discuss past and present issues in psycholinguistics (including controversial issues and the theoretical and historical roots of…

Different models of spoken word production make different predictions regarding the extent of effects of certain word properties on the output of that model. This article examines these predictions with regard to the effect of these variables on the production of semantic and phonological errors by aphasic subjects. (60 references) (Author/CK)

Two studies of adult aphasia, focusing on phonological disturbances, are presented. In the first study, subjects were 15 adults wit moderate aphasia and five age-matched controls. A variety of speech production and speech perception tests were administered, including tests of syllable discrimination, auditive word-picture matching, articulation,…

This survey consists of eleven papers covering current topics within the realm of linguistic science. The papers are written by scholars in particular fields, and each one is followed by a list of references and critiques by other linguists. Current theories are discussed and reference is made to recent studies and writings. The areas of…

Consonant harmony, a complex phonological assimilation in which segments (usually consonants, but sometimes even vowels) become identical, which occurs in the speech of young children and adult aphasics, is analyzed, particularly as it occurs in Finnish-speakers. Consonant harmony has an articulatory basis: it is a trend toward repetition of the…
