How old one feels�one�s subjective age�has been shown to predict important psychological and health outcomes. The current studies examined the effect of taking a standard memory test on older adults� subjective age. Study 1 showed that older adults felt older after taking a standard neuropsychological screening test and participating in a free-recall experiment than they felt at baseline. Study 2 showed that the effect was selective to older adults: Younger adults� subjective age was not affected by participating in the memory experiment. Study 3 showed that the subjective-aging effect was specific to memory, as taking a vocabulary test for a similar amount of time did not affect older adults� subjective age. Finally, Study 4 showed that simply expecting to take a memory test subjectively aged older adults. The results indicate that being in a memory-testing context affects older adults� self-perception by making them feel older.
