Down syndrome (DS) is an intellectual disability (ID) disorder in which language and specifically, verbal fluency are strongly impaired domains; nearly all adults show neuropathology of Alzheimer's disease (AD), including amyloid deposition by their fifth decade of life. In the general population, verbal fluency deficits are considered a strong AD predictor being the semantic verbal fluency tas...

Objective Verbal fluency tests are widely used for the assessment of executive functions. However, traditional versions of the test depend on several cognitive factors beyond these components. The aim of this study was to evaluate the associations of a modified version of the verbal fluency with specific measures of executive functions. Methods Sixty adults were evaluated using traditional ve...

Recent studies in the West have found that verbal fluency tests are useful in the detection of dementia. In this study, the Fuld Verbal Fluency Test (FVFT) was modified and tested for its usefulness as a screening instrument for differentiating demented from normal elderly Chinese in Hong Kong. Fifty-three normal and 56 demented subjects were administered the FVFT, the Cantonese version of the ...

Introduction. Deep brain stimulation of the subthalamic nucleus (STN-DBS) in Parkinson's disease (PD) has been linked to a decline in verbal fluency. The decline can be attributed to surgical effects, but the relative contributions of the stimulation parameters are not well understood. This study aimed to investigate the impact of the frequency of STN-DBS on the performance of verbal fluency ta...

In the present study we examined the relation between alphabet knowledge fluency (letter names and sounds) and letter writing automaticity, and unique relations of letter writing automaticity and semantic knowledge (i.e., vocabulary) to word reading and spelling over and above code-related skills such as phonological awareness and alphabet knowledge. These questions were addressed using data fr...

when asked, “how many animals of each kind did Moses take on the Ark?“ most people respond “Two“ despite knowing that noah rather than Moses was the biblical actor. Two experiments tested the role of processing fluency in the detection of such semantic distortions by presenting questions in an easy or difficult to read print font. As predicted, low processing fluency facilitated detection of th...

We assessed the English vocabulary and verbal fluency of college students who were either bilinguals who were born abroad and spoke English or monolingual speakers of English. We examined the relationship between age of arrival to the U.S. of bilinguals and their English vocabulary. The bilinguals' performance on English vocabulary was in the average range. However, despite arriving to the U.S....

Background Performance on the verb fluency (VF) task may be influenced by administration procedures and demographic factors of each population. Objective The aim of this study was to verify whether the previous administration of semantic and phonemic verbal fluency tasks can influence performance on VF; and to analyze the correlation of VF performance with education, age and type of errors in...

BACKGROUND Psychosocial work characteristics may predict cognitive functioning after retirement. However, little research has explored specific cognitive domains associated with psychosocial work environments. Our study tested whether exposure to job demands, job control and their combination during working life predicted post-retirement performance on eight cognitive tests. METHODS We used d...

Background: the speech fluency pattern attributed to individuals with Williams-Beuren syndrome (WBS) is supported by the effectiveness of the phonological loop. Some studies have reported the occurrence of speech disruptions caused by lexical and semantic deficits. However, the type and frequency of such speech disruptions has not been well elucidated. Aim: to determine the speech fluency profi...
