Abstract: | The research reported in this article focuses on processes that contribute to the repetition effect in 2-alternative forced-choice tasks and on how these processes change with age. An analytical approach is presented that allows researchers to discriminate between 2 components of performance. The results of Experiment 1 show that differences in the relative contributions of these 2 processes can produce differences in repetition effects between younger and older adults. Furthermore, as in the negative priming domain, increasing the contribution of 1 of these 2 components can eliminate this age difference. Together, the results argue against the practice of attributing age differences in repetition effects to deficits in any single cognitive process.
