Fuzzy Trace Theory (FTT) is not so much a model of false memory as a model of the interface between memory and higher reasoning processes. In origin, it was a response to findings about how the validity of solutions to reasoning problems is related to memory for background facts that determine which solutions are valid. More importantly, in FTT, memory-reasoning independence can be explained in terms of preferred modes of processing when one performs a memory task relative to when one performs a reasoning task. Fuzzy Trace Theory posits two types of memory processes, they are : Verbatim and Gist.
