Younger Adults Can Be More Suggestible than Older Adults: The Influence of Learning Differences on Misinformation Reporting

Abstract

ABSTRACTThe aim of the present investigation was to determine whether differences in the strength of original information influence adult age differences in susceptibility to misinformation. One-half of the younger and older adults watched a slide sequence once (one-trial learning) that depicted a theft, whereas the remaining participants viewed the slide sequence repeatedly to ensure that all critical details were encoded (criterion learning). Three weeks later and immediately prior to final testing, participants were asked questions that contained misleading information. As expected, the degree of initial learning influenced age differences in misinformation reporting. That is, when event memory was poorer for older than younger adults (in the criterion learning condition), older adults were more susceptible to misinformation than younger adults. However, when memory of the event was poor (in the one-trial learning condition), the younger adults reported more misled details than the older adults, possibly because the younger adults had better memory for the misleading information. Therefore, strength of initial memory influences the extent and direction of adult suggestibility and helps explain the discrepancy found across studies in this area.
