Objective. Reduced verbal fluency is a strikingly uniform finding following deep brain stimulation (DBS) for Parkinson's disease (PD). The precise cognitive mechanism underlying this reduction remains unclear, but theories have suggested reduced motivation, linguistic skill, and/or executive function. It is of note, however, that previous reports have failed to consider the potential role of an...
BACKGROUND There is evidence for specific age-related deficits in tasks of verbal fluency. OBJECTIVE The aim of the present study was to evaluate training and transfer effects after 3 weeks of telephone-based verbal fluency training in old age. METHODS Participants were assigned to one of three training groups, an active control group, or a no-contact control group. Training consisted of 15...
Ten patients with dementia of Alzheimer's type, 10 patients with progressive supranuclear palsy, and 10 patients with Huntington's disease were compared on two types of verbal fluency task--namely, initial letter fluency and category (semantic) fluency. The groups were carefully matched for overall level of dementia on the dementia rating scale, and were compared with 25 age matched normal cont...
Purpose: The purpose of this investigation was to examine the combined effects of educational kinesiology tasks and stuttering treatment on the fluency of a pre-school child who stutters. Method: This paper details a case study. After the initial diagnosis of a 3-year; 5-month old male with a very severe fluency disorder as indicated by the SSI-4, four months of a modified version of the Lidcom...
Category and letter fluency tasks have been used to demonstrate psychological and neurological dissociations between semantic and phonological aspects of word retrieval. Some previous neuroimaging and lesion studies have suggested that category fluency (semantic-based word retrieval) is mediated primarily by temporal cortex, while letter fluency (letter-based word retrieval) is mediated primari...
This article combines findings from cognitive psychology on the role of processing fluency in truth judgments with epistemological theory on justification of belief. We first review evidence that repeated exposure to a statement increases the subjective ease with which that statement is processed. This increased processing fluency, in turn, increases the probability that the statement is judged...
The authors examined whether math fluency was independent from untimed math and from reading using 314 pairs of school-aged twins drawn from the Western Reserve Reading and Math Projects. Twins were assessed through a 90-min home visit at approximately age 10 and were reassessed in their homes approximately 1 year later. Results suggested that the shared environment and genetics influenced the ...
fluency in a second language (l2) involves a quintessentially cognitive processing system that operates quickly and effectively. the perceived importance of researching fluency through a psycholinguistic lens has motivated the related l2 research to resort to current cognitive speaking-specific models. this study, drawing on levelt’s (1999a) psycholinguistic model, probed the deficiency sources...
Purpose This study surveyed didactic and clinical education in fluency disorders at undergraduate and graduate institutions in the United States that provide education in speech-language pathology to determine whether a previously observed reduction in requirements has continued since prior surveys (Yaruss, 1999; Yaruss & Quesal, 2002). Method The study involved a detailed questionnaire that ...
Category fluency tasks are an important component of neuropsychological assessment, especially when evaluating for dementia syndromes. The growth in the number of Spanish-speaking elderly in the United States has increased the need for appropriate neuropsychological measures and normative data for this population. This study provides norms for English and Spanish speakers, over the age of 50, o...
