Public education about memory was evaluated with a controlled intervention trial. Participants in group 1 (n = 273) attended a symposium covering memory-related topics and received a magazine with identical information. Group 2 (n = 141) only received the magazine. Participants were nonprofessionals and professionals aged between 29 and 88. Outcome measures were knowledge about memory and subjective experience. For nonprofessionals, knowledge increment was higher in group 1 than in group 2, indicating that an objective increment in knowledge is present in nonprofessionals after attending the symposium. No knowledge change occurred in professionals. Furthermore, participants were very satisfied after both interventions, even when knowledge transfer was limited. (Contains 1 figure and 2 tables.)
