Taub, Edward – Behavior Analyst, 2012
Constraint-induced (CI) therapy is a term given to a family of efficacious neurorehabilitation treatments including to date: upper extremity CI movement therapy, lower extremity CI movement therapy, pediatric CI therapy, and CI aphasia therapy. The purpose of this article is to outline the behavior analysis origins of CI therapy and the ways in…

Dragoy, Olga; Stowe, Laurie A.; Bos, Laura S.; Bastiaanse, Roelien – Journal of Memory and Language, 2012
Time reference in Indo-European languages is marked on the verb. With tensed verb forms, the speaker can refer to the past (wrote, has written), present (writes, is writing) or future (will write). Reference to the past through verb morphology has been shown to be particularly vulnerable in agrammatic aphasia and both agrammatic and…

Haley, Katarina L.; Jacks, Adam; de Riesthal, Michael; Abou-Khalil, Rima; Roth, Heidi L. – Journal of Speech, Language, and Hearing Research, 2012
Purpose: We explored the reliability and validity of 2 quantitative approaches to document presence and severity of speech properties associated with apraxia of speech (AOS). Method: A motor speech evaluation was administered to 39 individuals with aphasia. Audio-recordings of the evaluation were presented to 3 experienced clinicians to determine…

Yamaguchi, Satoshi; Akanuma, Kyoko; Hatayama, Yuka; Otera, Masako; Meguro, Kenichi – International Journal of Rehabilitation Research, 2012
Patients with severe aphasia are rarely treated using speech therapy. We used music therapy to continue to treat a 79-year-old patient with chronic severe aphasia. Interventions 1, 2, and 3 were to practice singing a song that the patient knew, to practice singing a song with a therapist, and to practice saying a greeting using a song with lyrics,…

Westermann, Gert; Ruh, Nicolas – Psychological Review, 2012
We present a neural network model of learning and processing the English past tense that is based on the notion that experience-dependent cortical development is a core aspect of cognitive development. During learning the model adds and removes units and connections to develop a task-specific final architecture. The model provides an integrated…

Murray, Laura L. – American Journal of Speech-Language Pathology, 2012
Purpose: This study was designed to further elucidate the relationship between cognition and aphasia, with a focus on attention. It was hypothesized that individuals with aphasia would display variable deficit patterns on tests of attention and other cognitive functions and that their attention deficits, particularly those of complex attention…

Ferguson, Neina F.; Evans, Kelli; Raymer, Anastasia M. – American Journal of Speech-Language Pathology, 2012
Purpose: The effects of intention gesture treatment (IGT) and pantomime gesture treatment (PGT) on word retrieval were compared in people with aphasia. Method: Four individuals with aphasia and word retrieval impairments subsequent to left-hemisphere stroke participated in a single-participant crossover treatment design. Each participant viewed…

Kopkalli-Yavuz, Handan; Mavis, Ilknur; Akyildiz, Didem – Clinical Linguistics & Phonetics, 2011
Studies investigating voicing onset time (VOT) production by speakers with aphasia have shown that nonfluent aphasics show a deficit in the articulatory programming of speech sounds based on the range of VOT values produced by aphasic individuals. If the VOT value lies between the normal range of VOT for the voiced and voiceless categories, then…

Faroqi-Shah, Yasmeen; Graham, Lauren E. – Clinical Linguistics & Phonetics, 2011
Verb retrieval difficulties are common in aphasia; however, few successful treatments have been documented (e.g. Conroy, P., Sage, K., & Lambon Ralph, M. A. (2006). Towards theory-driven therapies for aphasic verb impairments: A review of current theory and practice. "Aphasiology", 20, 1159-1185). This study investigated the efficacy of a novel…

Hamilton, Roy H.; Chrysikou, Evangelia G.; Coslett, Branch – Brain and Language, 2011
One of the most frequent symptoms of unilateral stroke is aphasia, the impairment or loss of language functions. Over the past few years, behavioral and neuroimaging studies have shown that rehabilitation interventions can promote neuroplastic changes in aphasic patients that may be associated with the improvement of language functions. Following…

Meffert, Elisabeth; Tillmanns, Eva; Heim, Stefan; Jung, Stefanie; Huber, Walter; Grande, Marion – Journal of Psycholinguistic Research, 2011
Two important research lines in neuro- and psycholinguistics are studying natural or experimentally induced slips of the tongue and investigating the symptom patterns of aphasic individuals. Only few studies have focused on explaining aphasic symptoms by provoking aphasic symptoms in healthy speakers. While all experimental techniques have so far…

Gungor, Levent; Terzi, Murat; Onar, Musa Kazim – Brain and Language, 2011
Aphasia causes significant disability and handicap among stroke survivors. Language therapy is recommended for aphasic patients, but not always available. Piracetam, an old drug with novel properties, has been shown to have mild beneficial effects on post-stroke aphasia. In the current study, we investigated the effects of 6 months treatment with…

Kiran, Swathi; Grasemann, Uli; Sandberg, Chaleece; Miikkulainen, Risto – Bilingualism: Language and Cognition, 2013
Current research on bilingual aphasia highlights the paucity in recommendations for optimal rehabilitation for bilingual aphasic patients (Edmonds & Kiran, 2006; Roberts & Kiran, 2007). In this paper, we have developed a computational model to simulate an English-Spanish bilingual language system in which language representations can vary by age…

Jacks, Adam; Mathes, Katey A.; Marquardt, Thomas P. – Journal of Speech, Language, and Hearing Research, 2010
Purpose: To investigate the hypothesis that vowel production is more variable in adults with acquired apraxia of speech (AOS) relative to healthy individuals with unimpaired speech. Vowel formant frequency measures were selected as the specific target of focus. Method: Seven adults with AOS and aphasia produced 15 repetitions of 6 American English…

Knels, Christina; Danek, Adrian – Brain and Language, 2010
This article provides a detailed assessment of patient HT with a history of progressive language deterioration of approximately 6 years presenting now as a fluent jargon aphasic with severe impairment of both speech production and comprehension. Neuropsychological testing of non-verbal cognitive functions showed no impairment, leading to the…
