Abstract: ObjectivesActivating aging stereotypes can impair older adult performance on episodic memory tasks, an effect attributed to stereotype threat. Here, we report the first study comparing the effects of explicitly activating aging stereotypes at encoding versus retrieval on recollection accuracy in older adults.MethodDuring the encoding phase, older adults made semantic judgments about words, and during the retrieval phase, they had to recollect these judgments. To manipulate stereotype activation, participants read about aging-related decline (stereotype condition) or an aging-neutral passage (control condition), either before encoding or after encoding but before retrieval. We also assessed stereotype effects on metacognitive beliefs and two secondary tasks (working memory, general knowledge) administered after the recollection task.ResultsStereotype activation at encoding, but not retrieval, significantly increased recollection confusion scores compared to the control condition. Stereotype activation also increased self-reports of cognitive decline with aging, but it did not reliably impact task-related metacognitive assessments or accuracy on the secondary tasks.DiscussionExplicitly activating aging stereotypes at encoding increases the likelihood of false recollection in older adults, potentially by diminishing encoding processes. Stereotype activation also influenced global metacognitive assessments, but this effect may be unrelated to the effect of stereotypes on recollection accuracy.
