PURPOSE To compare the performance of hearing-impaired and normal-hearing people on phonologic and semantic verbal fluency tests. METHODS A cross-sectional study was conducted with 48 hearing-impaired adults and 42 individuals (control group) with no hearing or language complaints. Sociodemographic data were collected, as well as the characteristics of hearing loss and of the electronic audit...

Trait anxiety is thought to be associated with pathological anxiety, and a risk factor for psychiatric disorders. The present study examines the brain mechanisms associated with trait anxiety during the performing of verbal fluency tasks. The aim is to show how trait anxiety modulates executive functions as measured by verbal fluency, and to explore the link between verbal fluency and anxiety d...

Patients with schizophrenia show deficits across a broad spectrum of neurocognitive domains. In particular, deficits in verbal fluency are common. Verbal fluency tests are neuropsychological tests that assess frontal lobe function or executive function but also assess divergent thinking. However, few studies have considered the impairment of verbal fluency from the viewpoint of divergent thinki...

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...

I present VF-Clust, a system for computerized analysis of psychological tests of verbal fluency, which are used in clinical settings to detect and assess neurological pathologies such as Alzheimer’s disease. While the simple scoring of such tests may not be sensitive to underlying pathologies, more nuanced clustering analyses often are. Currently, clustering analyses on verbal fluency tests are...

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...

Objectives Cognitive deficits and language disorders, such as difficulty in word retrievals, are common among the elderly people. Verbal fluency as an index of word finding is one of the first cognitive functions that decline due to aging. Considering the lack of norms of verbal fluency in normal elderly Persian-speakers, the purpose of this research was to determine verbal fluency performance ...

BACKGROUND This study examines non-verbal (design) and verbal (phonemic and semantic) fluency in prodromal Huntington's disease (HD). An accumulating body of research indicates subtle deficits in cognitive functioning among prodromal mutation carriers for HD. METHODS Performance was compared between 32 mutation carriers and 38 non-carriers in order to examine the magnitude of impairment acros...

BACKGROUND There is evidence that alogia and formal thought disorder (FTD), two prominent speech symptoms in schizophrenia, are associated with different patterns of verbal fluency task deficits. Verbal fluency is thought to involve several cognitive mechanisms, including controlled retrieval, semantic memory, and context processing. METHODS The current research examined whether alogia and FT...
