For years, episodic memory has been seen as a function specific to each individual. Recently, however, the idea that some degree of similarity could exist between memories shared by a large number of individuals has arisen. This study examined the extent to which individuals can share similar memory representations of a public event as well as how this similarity is impacted by aging. Fifty-four young and forthy-three older participants completed an online survey in which they answered memory questions regarding the fall of the bridge Morandi in Italy on August 2018. In the survey, participants were invited to recall what they remembered about the event and to evaluate the extent to which they rehearsed the event or heard about it in the medias since its occurrence. Recall protocols were coded to measure the number of remembered details by each participant taken individually as well as how remembered details were shared across individuals. Results revealed that older adults recalled more details about the bridge fall and had higher across-participant similarity for remembered information than young adults. Results also showed that older adults heard about the event more often than young adults since August 2018, but it did not explain the observed age-difference in across-participant similarity. Together, these findings suggest that older adults share memory details for a common public to a greater extent than young adults and that across-participants memory similarity for a public event is not conditioned by the degree of exposure to the remembered episode in the media.
