“…In addition, phonemic analysis in the SVF task and semantic analysis in the PVF could also have been explored in order to adapt to the Brazilian context. International studies have also used this type of analysis when investigating the components of clustering and switching (Sauzéon et al, 2004;Tallberg et al, 2011). However, the adaptation of the method carried out in our study is the initial step to reinforce the use of PVF and SVF tasks, which is important to stimulate other researchers to further develop adaptations of appropriate methods for the Brazilian population.…”

“…In terms of this variation, international studies have found significant differences in the SVF performance between 7-8 years old and 9-10 years old; whereas, when it comes to PVF, the number of words retrieved significantly increases starting at 11-12 years (Sauzéon, Lestage, Raboutet, Kaoua, & Claverie, 2004;Tallberg, Carlsson, & Liberman, 2011). The literature shows that both adults and children have a better performance in SVF tasks in comparison with PVF tasks (Sauzéon et al, 2004;Strauss et al, 2006). This performance pattern is explained by the different cognitive components recruited during the tasks.…”

“…This performance pattern is explained by the different cognitive components recruited during the tasks. PVF tasks are associated with increased use of search strategies to retrieve words; therefore, these tasks depend more on the executive functions (such as cognitive flexibility and switching), which require greater cognitive effort (Sauzéon et al, 2004). As for SVF tasks, mental imaging strategies (imagining scenarios based on the category of words) facilitate response retrieval.…”

“…There are international studies of children samples (Hurks et al, 2010;Nieto, Galtier, Barroso, & Espinosa, 2008;Sauzéon et al, 2004;Tallberg, et al, 2011) and adult samples (Clark et al, 2012;Raboutet et al, 2010;Troyer, 2000;Troyer et al, 1997) with typical development.

The objective of this study was to describe an adaptation to Brazilian Portuguese of the methodological criteria for analysis of clustering and switching in semantic verbal fluency (SVF) and phonemic verbal fluency (PVF) tasks. The adaptation process consisted of six steps, including the selection of the clustering and switching variables based on data from a sample of 419 children and the analysis of inter-rater reliability (six raters). The following variables were scored: the total number of words generated the raw number of clusters, the mean cluster size, and the raw number of switches. There was a significant association between raters (intra-class correlation coefficients between 0.95 and 0.99), showing that the analytical method was reliable. Our study provides an evaluation of SVF and PVF tasks that goes beyond the overall score, making it possible to investigate the cognitive processes underlying this neuropsychological function. Keywords: semantic verbal fluency, phonemic verbal fluency, clustering, switching Critérios Metodológicos para Análises de Clustering e Switching em tarefas de Fluência VerbalResumo Este artigo objetiva apresentar uma adaptação ao português brasileiro dos critérios metodológicos para análises de clustering e switching em tarefas de fluência verbal semântica (FVS) e ortográfica (FVO). São descritas as seis etapas realizadas no processo de adaptação destes critérios, incluindo o processo de extração das variáveis de clustering e switching a partir de dados de amostras de crianças (N=419) e a análise da fidedignidade da concordância entre juízes (N=6). As variáveis avaliadas são número total de palavras evocadas, número de clusters, média do tamanho dos clusters e número de switches. Houve forte associação entre juízes (Coeficientes de Correlação Intraclasse entre 0,95 a 0,99) indicando fidedignidade do método de análise. Este estudo contribui com a avaliação da FVS e FVO para além do escore geral, permitindo investigar os processos cognitivos subjacentes a esta função neuropsicológica.

“…En el caso de los niños se observa el mismo patrón que los adultos, aunque la cantidad de ejemplares evocados en ambas tareas se incrementa entre los 6 y los 12 años alcanzando los niveles adultos entre los 11 y los 12 años (Anderson, et al, 2001;Nieto, Galtier, Barroso, & Espinosa, 2008;Sauzéon, Lestage, Raboutet, Kaoua, & Claverie, 2004;Temple, 1997;Van der Elst, et al, 2011). Jacobsen et al (2016) estudiaron en una población de niños brasileños de 6 a 12 años cómo inciden la edad y el tipo de escuela (pública y privada) en el rendimiento en tareas de FVS (evaluada con la categoría ropa en dos minutos), FVF (evaluada con el fonema /p/ en dos minutos) y una tarea de fluidez verbal en la cual los participantes debían evocar todo tipo de palabras, excepto nombres propios, en dos minutos y 30 segundos.…”

Intact fluency in autism? A comprehensive approach of verbal fluency task including word imageability and concreteness

et al. 2022

Verbal fluency is a cognitive function reflecting executive functions and the ability to retrieve the appropriate information from memory quickly. Previous studies reported conflicting results-impaired and intact verbal fluency-in autism spectrum disorder (ASD). Most studies concentrate on overall word productivity, errors, perseverations, clustering, or switching. We used a comprehensive approach to evaluate the reported discrepancy in the literature and introduced a new angle using the concept of word abstraction and imageability. Moreover, we analyzed the performance in two-time intervals (0-30 s and 31-60 s) to assess the temporal dynamics of verbal fluency and a possible activation or initiation deficit in autism. Sixteen adults with ASD and 16 neurotypical control participants, matched by gender, age, and education level, participated in our study. Contrary to our expectations, we did not find a significant difference between groups in word productivity, the number of errors, clustering, or temporal dynamics, neither in semantic nor in phonemic fluency tasks. Surprisingly, the two study groups' performance did not differ in terms of imageability or concreteness characteristics either. Our results raise the possibility that verbal fluency performance is intact in autism. We also suggest using a comprehensive approach when measuring fluency in autism. Lay summary: People with autism tend to think and communicate differently. In our study, we tested whether people with autism come up with more concrete or imageable words and whether their performance is better compared with neurotypicals in the beginning or in the later phase of a task measuring how many words they can produce in a minute. We did not detect any difference between the two groups; however, we recommend studying verbal fluency in autism from more and different angles in the future.
