Distribution of nouns, verbs, and adjectives in phonemic fluency tasks

The two ratios derived from fluency tasks are not directly comparable to those derived from corpora. The small-to-medium effect sizes of the variables studied and the subgroup patterns observed for the verb-noun ratio suggest that additional, as yet unexplored, factors contribute to grammatical category production in phonemic fluency. This study provides novel quantitative data regarding content word distributions in phonemic fluency and their demographic correlates. Future research should examine the potential clinical relevance of these ratios.
