You don't understand me! But, I do! Awareness of cross-generational differences in collective remembering of national historic events.

Collective memories refer to a group's shared representation of the past, which are slow to change over time. In this study, representative samples of American and German Younger Adults (YAs) and Older Adults (OAs) rated the emotional valence of 12 national historic events. Critically, both age groups were also asked to take on the perspective of the other: OAs imagined how YAs feel, whereas YAs imagined how OAs feel about the same events today. The results replicated previous findings that OAs and YAs hold differing opinions on numerous events. Both age groups successfully recognised these different collective perceptions between generations to some extent. Yet, OAs were more accurate in the perspective-taking task, with YAs consistently underestimating the intensity of OAs' emotional valence. Self-reported perspective-taking strategies suggest that OAs relied more on stereotypes and considered education, while knowledge from specific people was universally used to rate the other age group's perspective.
