Henry L. Roediger III
Naturally, Roediger's approach to explaining this phenomenon was through retrieval processes. He thought that perhaps recalling list items would increase the availability of the lure word to a level where it became so available that it was mistaken for a presented word. However, retrieval processes alone were not enough to explain the findings – in a number of studies Roediger and his colleagues showed that a warning about developing a false memory had no effect if it was presented before retrieval, but could reduce false memories if presented before the encoding phase, suggesting an important role being played by the encoding process. Further work led Roediger and his research team to acknowledge both encoding and retrieval processes in explaining this phenomenon.
