Aging, source, and decision criteria: when false fame errors do and do not occur

Abstract

Two experiments investigated the influence of decision criteria on source memory performance of older adults and younger adults. Experiment 1 used the false fame paradigm, which encourages people to use relatively loose decision criteria when making what are, in essence, source judgments. Consistent with previous research, older adults made more false fame errors than younger adults. Experiment 2 was identical to Experiment 1 except that the fame judgments were made with the traditional source task format that encourages relatively stringent decision criteria when making source judgments: Possible sources were listed, and participants categorized names in terms of their source. In contrast to Experiment 1, older adults reduced their false fame errors to the level of younger adults. Encouraging older adults to use relatively stringent decision criteria when making source discriminations can reduce age differences in source misattributions.
