Background: Verbal fluency tasks, which require producing as many words in response to a cue in a fixed time, are widely used within clinical neuropsychology and in neuropsychological research. Although semantic word lists can be elicited, typically only the number of words related to the cue is interpreted thus ignoring any structure in the word sequences. Automated language techniques can pro...
The underlying nature of verbal fluency deficits in Alzheimer's disease (AD) was investigated in this study. Participants were 48 individuals with AD and 48 cognitively healthy older adults. Fluency performance on letter and category tasks was analyzed across two 30-s intervals for total words produced, mean cluster size, and total switches. Compared with the control group, AD participants prod...
OBJECTIVES This long-term prospective study focuses on the effects of electroconvulsive therapy (ECT) on everyday memory function and on semantic memory function. METHODS Results of memory test from 96 consecutive inpatients treated for unipolar depression were analyzed prospectively before ECT, after ECT treatment, and at 3- and 12-month follow-up. Everyday memory function was assessed by me...
Objectives: Lexical access is the process by which the basic conceptual, syntactical and morpho-phonological information of words are activated. Most studies of lexical access have focused on picture naming. There is hardly any previous research on other parameters of lexical access such as verbal fluency and analysis of connected speech in Persian normal participants. This study investigates t...
A meta-analysis of 30 studies with 1,269 participants was conducted to investigate the sensitivity of tests of verbal fluency to the presence of traumatic brain injury (TBI). As has been found for patients with focal frontal lobe injuries (but not for patients with focal temporal lobe lesions), TBI patients were comparably impaired on tests of phonemic and semantic fluency. The phonemic fluency...
Lexical fluency tests are frequently used in clinical practice to assess language and executive function. As part of the Spanish multicenter normative studies (NEURONORMA project), we provide age- and education-adjusted norms for three semantic fluency tasks (animals, fruit and vegetables, and kitchen tools), three formal lexical tasks (words beginning with P, M, and R), and three excluded lett...
