Objective: Mild Cognitive Impairments (MCI) is a transitional state in aging between normal cognition and dementia. The current study investigated whether MCI status moderated the effect of time on word generation during phonemic and category verbal fluency tasks. The objective was to determine whether MCI status had differential effects on initial automatic or latter more effortful retrieval processes of word generation. Method: Participants were community residing older adults enrolled in a longitudinal cohort study.Of the 411 participants (age = 76.42 ± 6.69; %female = 56.7), 356 were normal and 55 were diagnosed with MCI. Phonemic and category fluency were each administered for 60 s, but performance was recorded at three consecutive 20-second intervals. Separate linear mixed effects models for each fluency task were used to determine the effects of group, time, and their interaction on word generation. Results: In both fluency tasks, word generation declined as a function of time....
