Purpose: Core lexicon measures have received growing attention in research. They are intended to provide clinicians with a clinician-friendly means to quantify word retrieval ability in discourse based on normal expectations of discourse production for specific discourse elicitation tasks. To date, different criteria have been used to develop core…

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…

Aphasia as a multifaceted language disorder associated with the complicated links between language and brain has been and is of interest and significance to the stream of research in different disciplines including neurolinguistics, psycholinguistics, cognitive studies and language acquisition. Along with explorations into the manifestations of…

Background: Previous studies of therapy for acquired anomia have treated nouns in isolation. The effect on nouns in connected speech remains unclear. In a recent study in 2012, we used a novel noun syntax therapy and found an increase in the number of determiner plus noun constructions in narrative after therapy. Aims: Two aims arose from the…

We investigate the on-line processing of verb-phrase ellipsis (VPE) constructions in two brain injured populations: Broca's and Anomic aphasics. VPE constructions are built from two simple clauses; the first is the antecedent clause and the second is the ellipsis clause. The ellipsis clause is missing its verb and object (i.e., its verb phrase…

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,…

Russian patients with different types of aphasia experienced different problems in their performance on two types of linguistic operations. The efferent motor group exhibited more grammatico-structural disturbances, while the afferent motor and sensory aphasics exhibited grammatico-semantic disturbances. (Author/RL)

Develops the distinction between "referential" and "modalizing" aspects of language and describes their functional dissociation, as observed in various manifestations of aphasia and in the speech of hemispherectomy and commissurotomy patients. (Author/JL)

This paper analyzes aphasia using Titone's Glossodynamic Model which assumes the existence of three hierarchic levels of personality. (CFM)

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)

The spontaneous speech of five aphasic Ss (47-70 years old) was rated on-line by four clinicians to test the reliability of seven response categories (devised for the concurrent evaluation of aphasic speech). (Author/PHR)

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…

Summarizes the results of Finnish studies dealing with single-word experiments with aphasics as well as lexical decisions and eye-movement registration tests performed on normals. It then proposes a processing model for Finnish nouns, Stem Allomorph/Inflectional Decomposition (SAID), which predicts that both inflected and productive derived forms…

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…
