Direct linkRochon, 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…

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…

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…

Schattka, Kerstin I.; Radach, Ralph; Huber, Walter – Neuropsychologia, 2010
Based on recent progress in theory and measurement techniques, the analysis of eye movements has become one of the major methodological tools in experimental reading research. Our work uses this approach to advance the understanding of impaired information processing in acquired central dyslexia of stroke patients with aphasia. Up to now there has…

Warren, Jane E.; Crinion, Jennifer T.; Ralph, Matthew A. Lambon; Wise, Richard J. S. – Brain, 2009
Focal brain lesions are assumed to produce language deficits by two basic mechanisms: local cortical dysfunction at the lesion site, and remote cortical dysfunction due to disruption of the transfer and integration of information between connected brain regions. However, functional imaging studies investigating language outcome after aphasic…

Purpose: In this article, the authors encapsulate discussions of the Language Work Group that took place as part of the Workshop in Plasticity/NeuroRehabilitation Research at the University of Florida in April 2005. Method: In this narrative review, they define neuroplasticity and review studies that demonstrate neural changes associated with…

Rothi, Leslie J. Gonzalez; Musson, Nan; Rosenbek, John C.; Sapienza, Christine M. – Journal of Speech, Language, and Hearing Research, 2008
Purpose: This article introduces a collection of consensus statements regarding the application of neuroplasticity principles to rehabilitation of dysphagia, dysarthria, apraxia, and aphasia.

Thompson, Cynthia K.; Choy, Jungwon Janet – Journal of Psycholinguistic Research, 2009
This paper reports the results of three studies examining comprehension and real-time processing of pronominal (Experiment 1) and Wh-movement (Experiments 2 and 3) structures in agrammatic and unimpaired speakers using eyetracking. We asked the following questions: (a) Is off-line comprehension of these constructions impaired in agrammatic…

Broca's area has been considered, for over a century, as the brain centre responsible for speech production. Modern neuroimaging and neuropsychological evidence have suggested a wider functional role is played by this area. In addition to the evidence that it is involved in syntactical analysis, mathematical calculation and music processing, it…

Robin, Donald A.; Jacks, Adam; Hageman, Carlin; Clark, Heather M.; Woodworth, George – Brain and Language, 2008
This investigation examined the visuomotor tracking abilities of persons with apraxia of speech (AOS) or conduction aphasia (CA). In addition, tracking performance was correlated with perceptual judgments of speech accuracy. Five individuals with AOS and four with CA served as participants, as well as an equal number of healthy controls matched by…

Baker, Jonathan C.; LeBlanc, Linda A.; Raetz, Paige B. – Analysis of Verbal Behavior, 2008
Aphasia is an acquired language impairment that affects over 1 million individuals, the majority of whom are over age 65 (Groher, 1989). This disorder has typically been conceptualized within a cognitive neuroscience framework, but a behavioral interpretation of aphasia is also possible. Skinner's (1957) analysis of verbal behavior proposes a…

Burton, Martha W. – Clinical Linguistics & Phonetics, 2009
Lesion studies have demonstrated impairments of specific types of phonological processes. However, results from neuropsychological studies of speech sound processing have been inconclusive as to the role of specific brain regions because of a lack of a one-to-one correspondence between behavioural patterns and lesion location. Functional…

Five nonfluent aphasia patients participated in a picture-naming treatment that used an intention manipulation (opening a box and pressing a button on a device in the box with the left hand) to initiate naming trials and was designed to re-lateralize word production mechanisms from the left to the right frontal lobe. To test the underlying…

Pickering, Martin J.; Ferreira, Victor S. – Psychological Bulletin, 2008
Repetition is a central phenomenon of behavior, and researchers have made extensive use of it to illuminate psychological functioning. In the language sciences, a ubiquitous form of such repetition is "structural priming," a tendency to repeat or better process a current sentence because of its structural similarity to a previously experienced…

Yeung, Olivia; Law, Sam-Po; Yau, Monna – International Journal of Language & Communication Disorders, 2009
Background: While various treatment approaches have been shown to be effective in remediating word-finding difficulties in aphasic individuals, interest has recently been directed at the role of executive functions in affecting treatment outcomes. Aims: To examine the existence of a possible relationship between treatment generalization and…
