Age-Related Differences in Performance of Phonemic Verbal Fluency Measured by Controlled Oral Word Association Task (COWAT): A Meta-Analytic Study

Abstract: Meta-analytical procedures were used to examine the research findings on age-related changes in phonemic verbal fluency measured by the Controlled Oral Word Association Task (COWAT). Data from 26 studies comparing adults from different age ranges were analyzed. An effect of aging was found in almost all age comparisons especially after 40 years of age. Results revealed a decline of this verbal ability after 60 years, which accelerates through the late 80s. Gender may influence COWAT performance after the sixth… Show more

“…Os resultados na literatura, nem sempre concordantes, apontam, de um modo geral, para diferenças reduzidas entre adultos e idosos, relativamente à memória a curto prazo (Craik, 2000;Pinto, 1999). O desempenho mais baixo dos idosos no teste de Fluência Verbal de categorias, considerado, por alguns autores, como um instrumento de avaliação da memória de trabalho, mais especificamente do componente executivo central (Gaonac'h & Larigauderie, 2000) e, por outros, como teste das funções executivas (Ardila et al, 2000) está em consonância com alguns resultados obtidos em diversos estudos (Rodríguez-Aranda & Martinussen, 2006). Na análise do desempenho de memória a longo prazo (evocação imediata e diferida da história incluída na GSS 1) não foram encontradas diferenças estatisticamente significativas entre os dois grupos de participantes.…”

“…É que, à medida que a idade aumenta, o desempenho da memória episódica diminui (Balota, Dolan, & Duchek, 2000;Haaland, Price, & Larue, 2003;Lieberman, 2002;Pinto, 1999;Verhaeghen & Salthouse, 1997), bem como a capacidade de memória de trabalho (Gaonac`h & Larigauderie, 2000) e as funções executivas (Ardila, Pinela, & Rosselli, 2000;Rodríguez-Aranda & Martinussen, 2006). Note-se que as diferenças observadas na memória episódica dependem das estratégias de recuperação utilizadas: quando a memória é avaliada através do reconhecimento, o decréscimo do desempenho nos idosos é pequeno comparativamente ao que sucede com a evocação livre (e.g., Craik, Byrd, & Swanson, 1987).…”

“…In this sense, cued verbal fluency is mainly considered to be a valuable task for the assessment of executive/frontal function [50]. Age-related changes in cued verbal fluency is a well-documented effect [73][74][75][76][77][78][79]. Although further efforts are needed to clearly demonstrate and comprehend it, some authors have reported a differential involvement depending on the cue type.…”
