Marangolo, Paola; Bonifazi, Silvia; Tomaiuolo, Francesco; Craighero, Laila; Coccia, Michela; Altoe, Gianmarco; Provinciali, Leandro; Cantagallo, Anna – Neuropsychologia, 2010
The pervasiveness of word-finding difficulties in aphasia has motivated several theories regarding management of the deficit and its effectiveness. Recently, the hypothesis was advanced that instead of simply accompanying speech gestures participate in language production by increasing the semantic activation of words grounded in sensory-motor…

Rochon, Elizabeth; Leonard, Carol; Burianova, Hana; Laird, Laura; Soros, Peter; Graham, Simon; Grady, Cheryl – Brain and Language, 2010
Functional magnetic resonance imaging (fMRI) was used to investigate the neural processing characteristics associated with word retrieval abilities after a phonologically-based treatment for anomia in two stroke patients with aphasia. Neural activity associated with a phonological and a semantic task was compared before and after treatment with…

Miozzo, Michele; Fischer-Baum, Simon; Postman, Jeffrey – Neuropsychologia, 2010
We report the case of an English-speaking aphasic patient (JP) with left posterior-frontal damage affecting the inferior frontal and precentral gyri. In speaking, JP was impaired with the regular inflections of nouns and pseudonouns, making errors like "pears" instead of "pear" or "door" for "doors", while the spoken production of noun stems and…

Zanini, Sergio; Angeli, Valentina; Tavano, Alessandro – Clinical Linguistics & Phonetics, 2011
We report on the case of an elderly bilingual woman presenting with a diagnosis of primary progressive aphasia. The participant's native language was Friulian (L1), a predominantly oral Romance language, and her second language was Italian (L2), formally learned at primary school in oral and written forms. We investigated her linguistic abilities…

Mirman, Daniel; Yee, Eiling; Blumstein, Sheila E.; Magnuson, James S. – Brain and Language, 2011
We used eye-tracking to investigate lexical processing in aphasic participants by examining the fixation time course for rhyme (e.g., "carrot-parrot") and cohort (e.g., "beaker-beetle") competitors. Broca's aphasic participants exhibited larger rhyme competition effects than age-matched controls. A re-analysis of previously reported data (Yee,…

Buchsbaum, Bradley R.; Baldo, Juliana; Okada, Kayoko; Berman, Karen F.; Dronkers, Nina; D'Esposito, Mark; Hickok, Gregory – Brain and Language, 2011
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,…

Ball, Martin J., Ed.; Müller, Nicole, Ed.; Nelson, Ryan L., Ed. – Psychology Press, Taylor & Francis Group, 2013
This volume provides a comprehensive and in-depth handbook of qualitative research in the field of communication disorders. It introduces and illustrates the wide range of qualitative paradigms that have been used in recent years to investigate various aspects of communication disorders. The first part of the Handbook introduces in some detail the…

Goldfarb, Robert; Bekker, Natalie – Journal of Communication Disorders, 2009
This study investigated noun-verb retrieval patterns of 30 adults with chronic undifferentiated schizophrenia and 67 typical adults, to determine if schizophrenia affected nouns (associated with temporal lobe function) differently from verbs (associated with frontal lobe function). Stimuli were homophonic homographic homonyms, balanced according…

Schneider, Harry D.; Hopp, Jenna P. – Clinical Linguistics & Phonetics, 2011
Minimally verbal children with autism commonly demonstrate language dysfunction, including immature syntax acquisition. We hypothesised that transcranial direct current stimulation (tDCS) should facilitate language acquisition in a cohort (n = 10) of children with immature syntax. We modified the English version of the Bilingual Aphasia Test (BAT)…

Levy, Erika S.; Goral, Mira; De Diesbach, Catharine Castelluccio; Law, Franzo, II – Clinical Linguistics & Phonetics, 2011
This study documents patterns of change in speech production in a multilingual with aphasia following a cerebrovascular accident (CVA). EC, a right-handed Hebrew-English-French trilingual man, had a left fronto-temporo-parietal CVA, after which he reported that his (native) Hebrew accent became stronger in his (second language) English. Recordings…

Centeno, Jose G.; Anderson, Raquel T. – Clinical Linguistics & Phonetics, 2011
Spoken verb tense use in three groups of Spanish speakers with expressive limitations, namely, children with specific language impairment, bilingual children with first language (L1) (Spanish) attrition and adults with agrammatism, was compared in order to examine the possible impact of conversational tense frequency on expressive production.…

Vasanta, D.; Suvarna, A.; Sireesha, J. – Indian Journal of Applied Linguistics, 2010
The focus of this paper is application of the concept of "sonority" to the study of aphasic speech. An assessment tool that is capable of examining sonority effects was developed and administered to a patient diagnosed to have progressive non-fluent aphasia. This tool successfully distinguished the performance of the patient from that of two…

Richardson, Fiona M.; Thomas, Michael S. C.; Price, Cathy J. – Journal of Cognitive Neuroscience, 2010
Semantically reversible sentences are prone to misinterpretation and take longer for typically developing children and adults to comprehend; they are also particularly problematic for those with language difficulties such as aphasia or Specific Language Impairment. In our study, we used fMRI to compare the processing of semantically reversible and…

Sidiropoulos, Kyriakos; Ackermann, Hermann; Wannke, Michael; Hertrich, Ingo – Brain and Cognition, 2010
This study investigates the temporal resolution capacities of the central-auditory system in a subject (NP) suffering from repetition conduction aphasia. More specifically, the patient was asked to detect brief gaps between two stretches of broadband noise (gap detection task) and to evaluate the duration of two biphasic (WN-3) continuous noise…

Parkinson, R. Bruce; Raymer, Anastasia; Chang, Yu-Ling; FitzGerald, David B.; Crosson, Bruce – Brain and Language, 2009
Few studies have examined the relationship between degree of lesion in various locations and improvement during treatment in stroke patients with chronic aphasia. The main purpose of this study was to determine whether the degree of lesion in specific brain regions was related to magnitude of improvement over the course of object and action naming…
