pseudomemory

n. a fake memory, such as a spurious recollection of events that never took place, as opposed to a memory that is merely inaccurate. Pseudomemory is a cause of particular concern when using hypnosis to help eyewitnesses retrieve memories (see hypermnesia). It was formerly called pseudomnesia. See also confabulation; false memory; recovered memory.
