“…The current results on semantic verbal fluency are in line with many previous studies, including analysis using large sample, that sex is not a significant predictor for semantic verbal fluency tasks, and education positively correlates, whereas age correlates negatively with verbal fluency performance (Brickman et al, 2005;Capitani et al, 1998;Dursun et al, 2002;Tombaugh et al, 1999). The found sex differences in the emotional verbal fluency are not related to general differences in brain structure and activity of central neural system in men and women.…”

“…The possible types of the tasks of verbal fluency are phonemic (letters A, B, K), semantic (Animals, Fruits, Vehicles), affective (Pleasant, Joy, Love, Unpleasant, Hate, Fear), neutral (Fruits, Vehicles), animate (Animals), or inanimate (Vehicles). In sum, the findings on neutral verbal (phonemic and semantic) fluency are mixed (Brickman et al, 2005, Dursun et al, 2002, Weiss et al, 2003. Sex differences may concern the affective, but not the neutral tasks.…”

“…Influence of education on verbal fluency performance is opposite to age's influence; education increases the number of switches and words. Evidence that the data on verbal fluency are mixed can be found in another study which showed that women had worse results on phonemic verbal fluency than men, and that their results tended to decrease with age (Dursun et al, 2002). To the contrary, another result showed the lack of evidence for the interaction between age and sex for phonemic and semantic verbal fluency (Crossley et al, 1997).…”

Many factors such as intelligence, age, education, and sex may have an important influence on verbal fluency according to literature. The aim of this study is to examine the possible impact of the emotional schemata associated with sex differences on verbal fluency performances. Four tasks of verbal fluency were used in this study: two tasks of semantic verbal fluency (Animals, Vehicles) and two tasks of affective verbal fluency (PleasantJoy, Unpleasant-Fear). The results were analysed for 302 adults aged 18 to 70 years old. The number of correctly enumerated words, the number of phonemic clusters, the number of semantic clusters, and the number of phonemic and semantic switches were recorded. The results confirmed data that sex explains a little variance of results in verbal fluency performance; sex is not a predictor of semantic verbal fluency, but a significant predictor for emotional verbal fluency. Significant differences in verbal fluency between men and women were found only in emotional tasks. The hypothesis about the unconscious emotional schemata and linguistic fluency associated with sex differences was formulated.

“…Whether or not reductions of verbal fluency occur until the late 70s is still debated (Brady et al, 2001;Bryan et al, 1997;Dursun et al, 2002;Isingrini & Vazou, 1997;Kempler et al, 1998;Mathuranath et al, 2003;Mejia et al, 1998;Rodriguez-Aranda, 2003). It has been argued, that age-related deficits in verbal fluency may exclusively be due to general cogntive slowing (Bryan et al, 1997;Rodriguez-Aranda, 2003).…”

Normal aging has been associated with executive control deficits, but it is as yet unclear whether different executive subprocesses are differentially affected during the course of aging. The present study aimed to investigate age effects on a range of executive control subcomponents. Four consecutive age groups (20-30 years, 31-45 years, 46-60 years, 61-75 years), matched on present state IQ and mood, were compared on tasks of strategic memory processing, verbal fluency, reasoning, inhibition, task management, and self-rating of executive abilities. Deficits concerning the suppression of habitual and experimentally induced prepotent response tendencies and the ability to efficiently divide attention were observed in subjects over 60 years of age compared to the younger groups, while memory, verbal fluency, and reasoning were largely unaffected. Results suggest a sharp decline of executive function after age 60 and a differential course of different executive subcomponents across aging, adding further support to a multi-dimensional model of executive function.

“…Closely related to semantic fluency is the skill of naming ability, which relies on input from temporally based semantic networks and frontally based phonemic retrieval processes (Melrose et al ., ). Many authors describe the influence of age (e.g., Acevedo et al ., ; Barry, Bates, & Labouvie, ; Brickman et al ., ; Zimmermann, Parente, Joanette, & Fonseca, ) and education (e.g., Dursun, Robertson, Bird, Kutcher, & Kutcher, ; Moraes et al ., ; Ratcliff et al ., ; da Silva, Petersson, Faísca, Ingvar, & Reis, ) on verbal fluency performance.…”
