Theory of Public Memory Manipulation(TPMM) shows that information could be correctively and effectively passed to target groups by changing information release parameters and by affecting and choosing the memory of target group. Firstly, TPMM is introduced to the research on public risk management. By adjusting the parameters, such as cue dependence, repetition, and novelty, a dynamic model indicating influences on the public perception of risk after dissemination of emergency public information is developed. The study finds that a reasonable choice of time, frequency, and information types when disseminating emergency public information, the public perception of risk in the case of public mental panic could be manipulated. It provides optimal strategies for public sectors to disseminate emergency public information in an accurate and effective way.
