‘Normal’ semantic–phonemic fluency discrepancy in Alzheimer's disease? A meta-analytic study [PDF]

Cortex, 2010
In a meta-analysis of 135 studies involving 6000 patients with Alzheimer's disease (AD) and 6057 healthy controls, we examined the relative degree of semantic and phonemic fluency impairment in AD patients. The effect size for semantic fluency (d = 2.10;

Standardization and normative data obtained in the Italian population for a new verbal fluency instrument, the phonemic/semantic alternate fluency test

Neurological Sciences, 2013
The phonemic/semantic alternate fluency test seems to overcome some limits of the instruments currently used to assess set-shifting abilities. In particular, this test does not make high demands on motor systems because the subject is required to rapidly

Phonemic Verbal Fluency and Midbrain Atrophy in Progressive Supranuclear Palsy

Journal of Alzheimer's Disease, 2021
Background: The neuropsychological profile of progressive supranuclear palsy (PSP) patients is mainly characterized by executive dysfunction, but the relationship between the latter and midbrain atrophy is still unclear. Objective: The aims of the study were to investigate which test evaluating executive functioning is more frequently impaired in PSP ...

Is there disproportionate impairment in semantic or phonemic fluency in schizophrenia?

Journal of the International Neuropsychological Society, 2003
Phonemic and semantic fluency involve the capacity to generate words beginning with particular letters or belonging to particular categories, respectively. The former has been associated with frontal lobe function and the latter with temporoparietal function, but neuroimaging studies indicate overlap of underlying neural networks.

Comparison of animal, action and phonemic fluency in aphasia

International Journal of Language & Communication Disorders, 2017
AbstractBackgroundThe ability to generate words that follow certain constraints, or verbal fluency, is a sensitive indicator of neurocognitive impairment, and is impacted by a variety of variables.AimsTo investigate the effect of post‐stroke aphasia, elicitation category and linguistic variables on verbal fluency performance.Methods & ...

Spatio-Temporal Cortical Dynamics of Phonemic and Semantic Fluency

Journal of Clinical and Experimental Neuropsychology, 2004
Hemodynamic brain imaging and lesion studies have suggested differential involvement of expressive language-related cortical regions based on the phonemic versus semantic characteristics of verbal cues. The aims of this study were: 1) to elucidate the relative timing of the activity of inferior frontal and anterior insular versus motor and ...

Modulating phonemic fluency performance in healthy subjects with transcranial magnetic stimulation over the left or right lateral frontal cortex

Neuropsychologia, 2017
A growing body of evidence have suggested that non-invasive brain stimulation techniques, such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), can improve the performance of aphasic patients in language ...

6 Semantic and Phonemic Fluency in Alcohol Dependent Individuals

Journal of the International Neuropsychological Society, 2023
Objective:Verbal fluency consists of semantic and phonemic fluency and is often used to detect verbal ability and executive control (Shao et al., 2014). While research has found general verbal fluency impairments in chronic alcohol use, few studies have examined semantic and phonemic fluency separately (Stavro et al., 2012; Stephan et al., 2017).

Distinct functional connectivity of the hippocampus during semantic and phonemic fluency

Neuropsychologia, 2015
Verbal fluency tasks are typically used in neuropsychological practice for assessment of language function in a variety of neurological disorders. Recently, it has been shown that the hippocampus, a region thought to be exclusive to the domain of memory, is also involved in tests of semantic fluency.

Phonemic Fluency in Portuguese-speaking Subjects in Brazil: Ranking of Letters

Journal of Clinical and Experimental Neuropsychology, 2006
Phonological verbal fluency studies in English most commonly employ the letters F-A-S as stimuli. We assessed the production of words with these and 14 other letters in Portuguese-speaking healthy subjects (n = 74). The letters F-A-S were ranked among the easiest to produce words in one minute, which is consistent with the findings of studies with ...
