Rohrer, Jonathan D.; Crutch, Sebastian J.; Warrington, Elizabeth K.; Warren, Jason D. – Neuropsychologia, 2010
The neuropsychological features of the primary progressive aphasia (PPA) syndromes continue to be defined. Here we describe a detailed neuropsychological case study of a patient with a mutation in the progranulin ("GRN") gene who presented with progressive word-finding difficulty. Key neuropsychological features in this case included gravely…

Faroqi-Shah, Yasmeen – Neuropsychologia, 2008
Errors in the production of verb inflections, especially tense inflections, are pervasive in agrammatic Broca's aphasia ("*The boy eat"). The neurolinguistic underpinnings of these errors are debated. One group of theories attributes verb inflection errors to disruptions in encoding the verb's morphophonological form, resulting from either a…

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…

Fischman, Mark G.; Christina, Robert W.; Anson, J. Greg – Research Quarterly for Exercise and Sport, 2008
Franklin Henry's "memory drum" theory of neuromotor reaction (Henry & Rogers, 1960) was one of the most influential studies of the response programming stage of information processing. The paper is the most-cited study ever published in the "Research Quarterly for Exercise and Sport." However, few people know there is a noteworthy error in the…

Bormann, Tobias; Kulke, Florian; Wallesch, Claus-W.; Blanken, Gerhard – Brain and Language, 2008
Within a discrete two-stage model of lexicalization, semantic errors and errors of omission are assumed to be independent events. In contrast, cascading and interactive models allow for an influence of word form on lexical selection and thus for an inherent relationship in accounting for both error types. A group of 17 aphasic patients was…

Dalemans, Ruth J. P.; de Witte, Luc; Wade, Derick; van den Heuvel, Wim – International Journal of Language & Communication Disorders, 2010
Background: Little is known about the way people with aphasia perceive their social participation and its influencing factors. Aims: To explore how people with aphasia perceive participation in society and to investigate influencing factors. Methods & Procedures: In this qualitative study thirteen persons with aphasia and twelve central…

Caplan, David; Waters, Gloria; Kennedy, David; Alpert, Nathanial; Makris, Nikos; DeDe, Gayle; Michaud, Jennifer; Reddy, Amanda – Brain and Language, 2007
This paper presents the results of a study of the effects of left hemisphere strokes on syntactically-based comprehension in aphasic patients. We studied 42 patients with aphasia secondary to left hemisphere strokes and 25 control subjects for the ability to assign and interpret three syntactic structures (passives, object extracted relative…

Kagan, Aura; Simmons-Mackie, Nina – Topics in Language Disorders, 2007
The current trend of the WHO that suggests that aphasia assessment and intervention strategies should be directly influenced by outcome goals related to life participation is presented.

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…

Banks, Sarah; Weintraub, Sandra – Brain and Cognition, 2008
Lack of insight is a core diagnostic criterion for behavioral variant frontotemporal dementia (bvFTD), and is believed to be intact in the early stages of primary progressive aphasia (PPA). In other neurological conditions, symptom-specific insight has been noted, with behavioral symptoms appearing especially vulnerable to reduced insight.…

Vukovic, Mile; Vuksanovic, Jasmina; Vukovic, Irena – Journal of Communication Disorders, 2008
In this study we investigated the recovery patterns of language and cognitive functions in patients with post-traumatic language processing deficits and in patients with aphasia following a stroke. The correlation of specific language functions and cognitive functions was analyzed in the acute phase and 6 months later. Significant recovery of the…

Erdeljac, Vlasta; Sekulic, Martina – Clinical Linguistics & Phonetics, 2008
This paper examines the relative values of syntactic-semantic relationships in the mental lexicon of aphasic patients, which were tested within syntagmatic and paradigmatic networks of lexical relations. Semantic relations, such as synonymy, antonomy, and hyperonymy, as well as collocational and coordinational syntactic-semantic relations, were…

Bloch, Steven; Beeke, Suzanne – Clinical Linguistics & Phonetics, 2008
This paper uses the methodology of conversation analysis (CA) to examine the practice of co-constructed turn and utterance production in impaired communication. An investigation of the conversations between two family dyads, featuring one person with dysarthric speech and one with aphasic language, reveals one way in which single turns and…

Hoffman, Paul; Jefferies, Elizabeth; Ehsan, Sheeba; Hopper, Samantha; Lambon Ralph, Matthew A. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2009
Semantic short-term memory (STM) patients have a reduced ability to retain semantic information over brief delays but perform well on other semantic tasks; this pattern suggests damage to a dedicated buffer for semantic information. Alternatively, these difficulties may arise from mild disruption to domain-general semantic processes that have…
