Subjects: Memory in old age, Reaction time, Word recognition
Abstract: Background/Study Context: This study examined the effect of age and response competition on implicit memory performance. Methods: Younger and older adults studied high- and low-frequency words and took a word stem completion test that could be completed with multiple solutions. To manipulate response competition, the test list consisted of word stems that could be completed with target low-frequency words, as well as multiple other solutions with higher frequencies than the target (the high response competition condition) and word stems that could be completed with target high-frequency words, as well as multiple other solutions with lower frequencies than the target (the low response competition condition). Results: Relative to younger adults, older adults showed reduced levels of priming only under conditions of high response competition (low-frequency targets with high-frequency competitors). Conclusion: In support of a response competition mechanism, older adults were more likely to complete stems with nonstudied high-frequency solutions than were younger adults. Results demonstrate that older adults have reduced priming compared with younger adults under some conditions of high response competition. [ABSTRACT FROM AUTHOR]
