Specifically, for the left fusiform/parahippocampal cluster, the analysis revealed, in successful agers, only a weak trend of reduced subsequent memory effect ( F (3, 181) = 3.492, p = .062, q = .062), driven by the only difference in the very old group relative to the young reference group ( p = .097, q = .062).
There was a significant age effect in the left lateral/middle occipital cluster, F (2, 241) = 4.585, p = .011, q = .035, where older adults had reduced occipital effect, and a marginally significant class effect, F (1, 241) = 3.337, p = .069, q = .148, such that successful agers had greater subsequent memory effect than average agers.
There was a trend toward significance in the ability to distinguish new pictures: older adults less often correctly identified new pictures as new ( p = .073) and were more likely to falsely recognize new pictures as old ( p = .077).
Statistical significance was determined at p = .05, and marginal significance ( p < .1) was also noted.
All significant effects survived multiple comparison correction for FDR ( q ’s < .05), whereas the marginal age × class interaction in the right fusiform/parahippocampal cluster and the marginal class effect in the left lateral/middle occipital cluster were no longer approaching significance ( q’ s > .15). 3.5.
