* Found to be significantly different between younger and older adults according to permutation tests; N = number of participants; t = time limit of the fluency task; $\overline{n}$ = average number of non-duplicate, valid responses per individual; $\frac{u}{\mathrm{\Sigma }n}$ = number of unique responses u divided by the sum of number responses n for all individuals in the group.
