Purpose: In this study, the authors explore a method of measuring physiologic and perceived stress in individuals with aphasia by investigating salivary cortisol reactivity and subjectively perceived stress in response to a standardized linguistic task. Method: Fifteen individuals with aphasia and 15 age-matched healthy controls participated in a…

Research has shown that Broca's and Wernicke's aphasic patients show different impairments in auditory lexical processing. The results of an experiment with form-overlapping primes showed an inhibitory effect of form-overlap for control adults and a weak inhibition trend for Broca's aphasic patients, but a facilitatory effect of form-overlap was…

Standard diagnostic procedures for assessing temporal-processing abilities of adult patients with aphasia have so far not been developed. In our study, temporal-order measurements were conducted using two different experimental procedures to identify a suitable measure for clinical studies. Additionally, phoneme-discrimination abilities were…

The effect of typicality of category exemplars on naming was investigated using a single subject experimental design across participants and behaviors in four patients with fluent aphasia. Patients trained on naming of atypical exemplars demonstrated generalization to naming of intermediate and typical items. However, patients trained on typical…

Crossed aphasia is a phenomenon in which an individual sustains a lesion in the right hemisphere (typically non-language dominant), but who exhibits an aphasic syndrome. The authors present a case study of an individual with crossed aphasia (CA) in an attempt to provide anecdotal information for four questions posed by Pita, Karavelis, and…

Speech-language pathologists (SLPs) who work with adults with cognitive-linguistic impairments, including aphasia, have long needed an assessment tool that predicts ability to function in the real world. In this article, it is argued that virtual reality (VR)-supported approaches can address this need. Using models of disability such as the…

Based in part on a M.S. thesis submitted to the University of Utah.

The oral expressive language of 47 aphasic subjects (who had suffered a single unilateral occlusive cerebral vascular accident two to four weeks prior to original testing) was measured on two occasions a year apart. Results found positive changes toward normal language functioning for several variables with type of aphasia affecting outcome on…

Aphasic (N=15) and non-brain-damaged adults listened to and retold two narrative stories three times in succession. Both aphasic and non-brain-damaged subjects were affected by story structure and increased the amount of information retold across retellings. Non-brain-damaged subjects retold slightly more (statistically insignificant) information…

Purpose: Multidimensional scoring methods yield valuable information about communication abilities. However, issues of training demands for valid and reliable scoring, especially in current service delivery contexts, may preclude common usage. Alternatives to multidimensional scoring were investigated in a sample of adults with aphasia. Method:…

The differential effects of normal and emphatic stress on the auditory comprehension performance of nine aphasic and five normal adults were assessed. The aphasic subjects demonstrated significantly better performance for stimuli presented with emphatic stress. (Author/DB)

Results of a seven-week sentence stimulation treatment on sentence production in an aphasic adult female with agrammatism indicated that treatment influenced description of test picture sets and that some generalization to other picture sets occurred. (Author/DB)

Fifteen aphasic and 15 normal adults demonstrated use of a right hemisphere visuospatial strategy to analyze printed whole words and word parts such as prefixes and suffixes. The performances of the two groups were similar, suggesting that the hypothesized strategy could be useful as a reading approach for aphasics. (Author/CL)
