Estrategias ejecutivas de búsqueda, recuperación y cambio en la fluidez verbal

Abstract

Verbal fluency tasks usually divide into semantic -evoking words of a category-and phonemic -evoking words that begin with a certain letter-, and carry a limited time. Such tasks demand the intervention of word search and retrieval -which require cognitive flexibility, working memory and inhibition (executive aspect)-and the organization, capacity and integrity of lexico-semantic memory (associative aspect). The first aspect is manifested in the amount of clusters and switches that a person can do, and the second, in the clusters size. In order to study those aspects, we administered semantic -category animals-and phonemic -letter p-verbal fluency tasks to 133 children of 1st, 3rdand 5thgrade from Mar del Plata. We found that cognitive control increased in the 3rdgrade, associated with a major fluency, but no changes were found within the associative aspect.
