Does previous presentation of verbal fluency tasks affect verb fluency performance?

Abstract

Background:Performance on the verb fluency (VF) task may be influenced by administration procedures and demographic factors of each population. Objective:The aim of this study was to verify whether the previous administration of semantic and phonemic verbal fluency tasks can influence performance on VF; and to analyze the correlation of VF performance with education, age and type of errors in Brazilian healthy elderly. Methods:Sixty-two participants were subdivided into experimental (semantic and the phonemic fluency tasks were administered before the VF) and control groups (VF only). The total score and the types of errors on the VF task were determined. Additional information was computed for the correlational analysis. Results:VF performance did not differ statistically between experimental and control groups, but correlated positively with education and negatively with intrusions. Conclusion:The lack of influence of other verbal fluency tasks on performance of the VF task in elderly individuals allows the use of this order of administration. A strong influence of educational level on VF task performance reinforces the need for further studies in different populations.

“…Third, the administration order of the VF tasks was the same in both conditions. There is the possibility of an order effect, but based on a previous study, we do not believe an order effect occurred, at least pertaining to the action VF task [27]. …”

“…For the unconstrained VF, the participants were asked to say as many words as possible, excluding names and numbers, within 2.5 minutes while keeping their eyes closed [26]. For the action fluency task, the participants were asked to say as many actions or “things that people can do” as possible within one minute [16, 27]. The instruction of these previous VF did not allow participants to say proper names or numbers.…”

Reading and writing habits as a predictor of verbal fluency in elders.

“…In the action verbal fluency, participants were instructed to say as many “things that people can do” (verbs) as they could during 1 min. It followed the administration originally proposed by Piatt, Fields, Paolo, and Tröster (1999) and adapted to the Brazilian population by Beber and Chaves (2016).…”

“…The relationship among age, education. and verbal fluency performance in the Brazilian population has already been established in previous studies (Beber & Chaves, 2016;Brucki, Malheiros, Okamoto, & Bertolucci, 1997;Fonseca et al, 2015;Machado et al, 2009;Zimmermann et al, 2014). However, these investigations did not include different types of verbal fluency task or evaluate the influence of cognitive impairment on performance.…”

Análise de clustering e switching da fluência de verbos em indivíduos com doença de Alzheimer

“…A fluência verbal de verbos é mais complexa do que as tarefas de fluência verbal que envolvem a geração de substantivos, pois os verbos possuem maior inflexão e maior relação sintática com outras palavras (7) . Além disso, quando evocados, os substantivos e verbos ativam áreas distintas no cérebro.…”
