Aging and the Questionable Validity of Recognition-Based Exposure Measurement

Growing evidence suggests that basic exposure measures, such as recognition-based items, might not operate identically among older and younger adults. We present two studies relevant to this debate. Study 1 provides experimental confirmation of the recognition decline hypothesis, finding an interaction between age and exposure in predicting recognition memory for an advertisement related to global warming. Study 2 assesses television news project evaluation data to explore whether verbatim detail recognition difficulty explains Study 1 results. The two studies provide complementary evidence, not only illustrating recognition decline among the elderly but also providing careful control of exposure in Study 1 and the use of multiple messages, realistic viewing scenarios, and free recall data in Study 2. Taken together, the studies offer a cautionary tale for campaign evaluators. On a broader theoretical level, the results suggest a fruitful path for communication research focused on the nuanced and potentially critical moderating role of age.
