The purpose of this study was to examine the norms of category fluency (CF) and design fluency (DF) tasks in adults of two age groups, examine the effects of gender, age, and other factors on both fluency tasks, and examine the relationship between the fluency tasks. The subjects in the young age group were 19 healthy adults aged 20 - 29 years, while the subjects in the older age group were 14 healthy adults aged 65 - 74 years. In the CF task, an ANOVA revealed that main effects of age, category were significant. Also, the age-gender interaction and age-category interaction were significant. In the DF task, an ANOVA revealed that a main effect of age was significant. There was no significant correlation between the fluency tasks. These results suggest that : 1) Further study is needed to provide the norms of DF task ; 2) The effects of gender, age, category are found in the CF task ; 3) The total number of answers in the DF task decreases with age ; 4) The CF and DF tasks are qualitatively different.
