Lost in the mall technique

From Wikipedia, the free encyclopedia

The "Lost in the Mall" technique is a controversial procedure that proponents believe can be used to create false memories. The technique was first developed by psychologist Elizabeth Loftus in an effort to explain how normal people can claim to have recovered memories of improbable experiences.

Loftus and her student Jacqueline Pickrell performed an experiment in which they gave participants short narratives, all supposedly provided by family members, describing childhood events, and asked them to recall the events. Unbeknownst to the participants, however, one of the narratives was false. It told of the person, as a child of 5 or 6, being lost in a shopping mall for an extended period of time before finally being rescued by an elderly person and reunited with his or her family. In the study, nearly 25% of the small sample of participants reported to be able to remember this event, even though it never actually occurred. Many people were able to provide embellishing details that were not supplied by the investigators. Loftus interpreted this to mean that the act of imagining the events led to the creation of false memories.

[edit] Criticisms of methodology and conclusions

One criticism of the initial study, which created the false memory of having been lost in a shopping mall, is that being lost in a store as a child is a common occurrence - perhaps the 25% who recalled the false memory had actually been lost in a mall as children, and were recalling that event.[citation needed]

Several studies and authors have found significant flaws in the Lost in the Mall study. A similar study by Pzedek in 1995 found that while researchers were able to duplicate the lost in the mall results with 15% of their subjects, a none of the study participants accepted an erroneous memory that they had received a painful enema as a child.[1][2] Crook states that the Lost in a Shopping Mall study’s application to therapy situations appears to be “limited to a narrowly defined and perhaps even unlikely situation” and states that the study’s “internal scientific methodological errors cast doubt on the validity of the claims” of the study.[3] [1]Crook also states that it has been demonstrated that the “methods, data, and assumptions in the mall study have not been subjected to rigorous scientific scrutiny” yet its results have been reported to the media to support the claim that “therapists can implant false memories of childhood trauma.”[2] Pope also questions the study. He questions the analogy of a memory of being lost in the mall as being equivalent to that of child rape. He also talks about the problem of confounding variables in the study. If an older family member claims to have seen the “false” memory, can a therapist make the same claim? And should this research be applied to “false” memories in therapy?[4][5] Others have also critiqued Loftus’ scholarship and accuracy[6] or that Loftus’ has done research that may contradict her own beliefs of recovered memories.

Loftus (1993) described the implanted traumatic event in the shopping-mall experiment as follows: "Chris was convinced by his older brother Jim, that he had been lost in a shopping mall when he was five years old" (p. 532). Does this seem, for example, a reasonable analogy for a five-year-old girl being repeatedly raped by her father?....Is it possible that the findings are an artifact of this particular design, for example, that the older family member claims to have been present when the event occurred and to have witnessed it, a claim the therapist can never make? To date, replications and extensions of this study have tended to use a similar methodology; that is, either the older family member makes the suggestions in his or her role as the experimenter's confederate, or the experimenter presents the suggestion as being the report of an older family member, thus creating a surrogate confederate.”
