Purpose: The current study aimed to identify objective acoustic measures related to affective state change in the speech of adults with post-stroke aphasia. Method: The speech of 20 post-stroke adults with aphasia was recorded during picture description and administration of the Western Aphasia Battery--Revised (Kertesz, 2006). In addition,…

Purpose: Apraxia of speech (AOS) is a consequence of stroke that frequently co-occurs with aphasia. Its study is limited by difficulties with its perceptual evaluation and dissociation from co-occurring impairments. This study examined the classification accuracy of several acoustic measures for the differential diagnosis of AOS in a sample of…

Purpose: Kiran and colleagues (Kiran, 2007, 2008; Kiran & Johnson, 2008; Kiran & Thompson, 2003) previously suggested that training atypical examples within a semantic category is a more efficient treatment approach to facilitating generalization within the category than training typical examples. In the present study, the authors extended…

Purpose: This study examined the content of 100 short scripts, co-constructed by persons with aphasia (PWA) and a clinician. The PWA subsequently learned the scripts by interacting with a computerized virtual therapist. The goal was to provide clinicians with ideas regarding content for treatment that is meaningful to PWAs. Method: Thirty-three…

This study asked whether aphasic adults show different noun/verb retrieval patterns based upon their clinical categorization as fluent or nonfluent. Participants selected either the noun or the verb meaning of target words, as presented in three contexts. The framework was that nouns (associated with temporal lobe function) are processed, stored,…

Three studies observed everyday communication of people with aphasia, traumatic brain injury, and in hospital. Simplification of real-life communication in the World Health Organization's International Classification of Functioning, Disability, and Health, variability of item sampling in existing assessments, and the complexity of real-life…

Two studies of adult aphasia, focusing on phonological disturbances, are presented. In the first study, subjects were 15 adults wit moderate aphasia and five age-matched controls. A variety of speech production and speech perception tests were administered, including tests of syllable discrimination, auditive word-picture matching, articulation,…
