False memory resources.  [Cautionary note:  Much of the web material on repressed/false memories--over 3 million pages now!--is heavily slanted toward one side of the debate or the other; instructors should caution students to think critically about any extreme claims regarding the prevalence of repressed memories or false memories.  A few of the more interesting web sources are listed below:]
“Remembering Dangerously.”  This is the full text of a very accessible article by Elizabeth Loftus, originally published in the Skeptical Inquirer in March, 1995.  It presents an analogy between the “repressed memory movement” and the Salem witch trials, now a classic argument of false memory advocates.  Not much laboratory data, but a few nice case study examples.
“Repressed memories and recovered memory therapy (RMT).”          Skeptical summary of RMT techniques and court decisions related to repressed memory claims.  Good list of references regarding false memories.
“False Memory Syndrome Facts” web page.  Clearly slanted, but does have links to some good articles and resources, and even "comic relief."
Follow-up exercise:  Ask students to read one or more of these resources and briefly report on what they find.  You might even organize a formal debate on the existence of repressed memories or the extent of the “problem” of false memories.
 
Eyewitness Test
