Background: The typicality effect is present in neurologically intact populations for natural, ad-hoc, and well-defined categories. Although sparse, there is evidence of typicality effects in persons with chronic stroke aphasia for natural and ad-hoc categories. However, it is unknown exactly what influences the typicality effect in this…

In this prospective study, data on incidence, stuttering characteristics, co-occurring speech disorders, and recovery of neurogenic stuttering in a large sample of stroke participants were assessed. Following stroke onset, 17 of 319 participants (5.3%; 95% CI, 3.2-8.3) met the criteria for neurogenic stuttering. Stuttering persisted in at least…

Several studies have reported improved naming using the semantic feature analysis (SFA) approach in individuals with aphasia. Whether the SFA can be modified and still produce naming improvements in aphasia is unknown. The present study was designed to address this question by using a modified version of the SFA approach. Three, rather than the…

Purpose: Individuals with probable Alzheimer disease (pAD) are frequently impaired at picture naming. This study examined whether a semantic elaboration task would facilitate naming in pAD, and whether training either semantically typical or atypical stimulus items facilitated generalized improvement in picture naming and category generation…

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…

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…

The study describes the Shewan Spontaneous Language Analysis (SSLA), establishes its reliability and validity, and reports on its use with 47 aphasic adults who had suffered a single unilateral occlusive cerebral vascular accident two to four weeks prior to testing and 30 normal adults.

This article describes the language development in a left-handed young child with a left middle cerebral artery infarction. Patterns of development observed between 36 and 60 months of age are described as a transient jargon or fluent aphasia possibly resulting from initial reliance on an uninjured right hemisphere. (Author/DB)

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…
