Abstract: The present study sought to determine whether participants with moderate to severe traumatic brain injury (MOD/S TBI) would quantitatively and qualitatively differ from participants with no brain damage (NBD) in phonemic and semantic verbal fluency, and whether the potential differences may be attributed to working memory (WM) and information processing speed. Independent t-test procedures indicated that the MOD/S TBI group was disproportionately impaired on all test measures when compared to an NBD group. However, when Bonferroni adjustments for multiple comparisons were applied, only two results remained statistically significant. First, the MOD/S TBI group differed significantly from the NBD group on the total number of correct words generated for the letter S on the phonemic verbal fluency task, and for the semantic categories of animals and boys' names. Second, the MOD/S TBI group produced a significantly greater number of word recall errors on a measure of WM when compared to participants with NBD. Moreover, a mixed-analysis of variance (ANOVA) procedures suggested that the MOD/S TBI group was impaired in their performance on tasks of information processing speed and WM, when compared to the NBD group, and these differences were correlated with decrements in performance on tasks of verbal fluency, as indicated by the total number of words produced on these tasks.
