Associations between memory and verbal fluency tasks

Abstract

Previous studies have provided inconsistent evidence concerning the association between delayed retrieval of story information from long-term memory and retrieval of words on verbal fluency tasks. The current study looks for shared retrieval mechanisms in these tasks from childhood to old age. Three-hundred and eighty participants (ages 5-91) performed tasks of story recall, digit span, phonemic fluency, and semantic fluency. Significant correlations between delayed story recall and both fluency tasks emerged in all age groups, and the contribution of delayed story recall to fluency performance remained significant when analyzing the combined effects of story recall and digit span. These findings suggest that retrieval of information through story recall and retrieval of words on fluency tasks may share similar cognitive components.
