Differential Effects of Aging on Two Verbal Fluency Tasks

Perceptual and Motor Skills, 1993
The effect of age on verbal fluency was studied in 84 healthy volunteers, ages 45 to 91 years, who performed letter-fluency and semantic-fluency tasks. Older subjects (75 to 91 yr.) performed as well as younger (50 to 64 yr.) on letter fluency but did significantly worse on semantic category fluency.

Switching and clustering in verbal fluency tasks throughout childhood

Journal of Clinical and Experimental Neuropsychology, 2008
An analysis of switching and clustering in fluency tasks was conducted on data from 180 Hebrew speakers aged 8-29. On the phonemic task, total output, number of switches, and number of clusters differed significantly across age groups and increased with age, whereas mean cluster size did not. On the semantic task, all measures increased with age.

A comparison of verbal fluency tasks in schizophrenic patients and normal controls

Schizophrenia Research, 2001
Previous studies have reported significant impairment on verbal fluency tasks (semantic and letter) among schizophrenic subjects. However, the possibility of specific categorical deficits has not been adequately investigated. Nor have the effects of task duration, the stability between testing sessions, and the relationship between intelligence and ...

The Emotional Verbal Fluency Task: A Close Examination of Verbal Productivity and Lexical-Semantic Properties

Journal of Speech, Language, and Hearing Research, 2020
Purpose Emotional verbal fluency (Emo-VF) has the potential to expand neuropsychological assessment by providing information about affective memory retrieval. The usability of Emo-VF is limited, however, by significant variations in task administration and the lack of information about Emo-VF responses.

Chronic pain patients' perceptions of their future: a verbal fluency task

Pain, 2016
Abstract Depression is a common feature of chronic pain, but the content of depressed cognitions in groups with chronic pain may be qualitatively different from other depressed groups. Future thinking has been extensively studied in depressed population; however, to our knowledge, this is the first study to investigate future thinking, using ...

Normative Data for Clustering and Switching on Verbal Fluency Tasks

Journal of Clinical and Experimental Neuropsychology, 2000
Normative data for clustering and switching on verbal fluency tasks are provided. Four hundred and eleven healthy adults between the ages of 18 and 91 were given tests of phonemic fluency (FAS or CFL) and semantic fluency (Animals and Supermarket). Raw scores were corrected for demographic (i.e., age, education, and sex) and test (i.e., fluency form ...

The Effects of Alzheimer's Disease on Item Output in Verbal Fluency Tasks.

Neuropsychology, 2004
We collected category fluency data from several moderate-to-large samples of participants at three different sites: the New York University Aging and Dementia Center, the Oregon Health Services Aging and Dementia Research Center, and the Einstein Aging Study at the Albert Einstein College of Medicine. These data were analyzed by calculating the average

Comparisons of Verbal Fluency Tasks in the Detection of Dementia of the Alzheimer Type

Archives of Neurology, 1992
The performances of 89 patients with dementia of the Alzheimer type (DAT) and 53 demographically matched elderly normal control subjects were compared on four verbal fluency measures (category, letter, first names, and supermarket fluency). Receiver operating characteristic curves were plotted to determine each fluency tasks' sensitivity (ie, true ...

Neuromagnetic cortical desynchronization during verbal fluency task

International Congress Series, 2005
Abstract Objective We aimed to investigate temporal and spatial dynamics of beta band desynchronization during verbal fluency task (VFT), which is known to reflect one of the frontal lobe functions. Method Ten healthy right-handed volunteers participated.

Cortical and subcortical influences on clustering and switching in the performance of verbal fluency tasks

Neuropsychologia, 1998
Impairments on lexical and semantic fluency tasks occur in both cortical and subcortical dementia. Recent reports that the average size of phonemic and semantic clusters is reduced in Alzheimer's disease (AD), but not in Parkinson's disease (PD) could support the hypothesis that in AD verbal fluency deficits arise from degraded memory storage while in ...
