A false memory is simply a memory that did not occur. An actual experience can become distorted as best illustrated by the Cog Lab experiment on false memories accessed through Argosy University.

At the finish of the given list, the participant is then shown a list of words in which he or she is to recall the words from the original list. A special distractor is inserted to the list, and this word, although highly relative in nature, was not in the original list. For example, the
