Lost in the Mall
"Lost in a Shopping Mall"�A Breach of Professional Ethics

ABSTRACT: The "lost in a shopping mall" study has been cited to support claims that psychotherapists can implant memories of false autobiographical information of childhood trauma in their patients. The mall study originated in 1991 as 5 pilot experiments involving 3 children and 2 adult participants. The University of Washington Human Subjects Committee granted approval for the mall study on August 10, 1992. The preliminary results with the 5 pilot subjects were announced 4 days later. An analysis of the mall study shows that beyond the external misrepresentations, internal scientific methodological errors cast doubt on the validity of the claims that have been attributed to the mall study within scholarly and legal arenas. The minimal involvement�or, in some cases, negative impact�of collegial consultation, academic supervision, and peer review throughout the evolution of the mall study are reviewed.

Key words: research ethics, false memories, mall study, autobiographical memory

The "lost in a shopping mall" study (Loftus & Pickrell, 1995) originated as five single-participant "pilot" experiments conducted at the direction of University of Washington researcher Elizabeth Loftus. Loftus (L oftus & Ketcham, 1994) described the study in terms that suggest that proper research guidelines were not followed in these pilot experiments. The results of the mall study continue to be misrepresented in the media in sworn testimony and in scholarly publications. The roles of mechanisms currently in place to ensure the integrity of such research are reviewed here.

    In cognitive psychology, the Activation/ Monitoring Theory (AMT) and the Fuzzy Trace Theory (FTT) are framework’s which account for the false memory findings in the DRM paradigm. Roediger & McDermott (1995) define false memories as “...either remembering events that never happened, or remembering them quite differently from the way they happened...”. The Activation Monitoring Theory is a well used theoretical explanation of the DRM paradigm. According to Roediger et al, 2001 (as cited in Sergi, Senese, Pisani & Nigro, 2004) the AMT suggests that false memories are due to a combination of two processes: these include spreading activation and a controlled monitoring process. Another theory that can account for the DRM paradigm is the Fuzzy Trace…

    Good afternoon everyone! I hope you all did well on the midterm exam we had last week. This course has been a very interesting challenge to tackle so far, and the assigned readings for Week Five were no exception. We learned through the assigned chapters and article on Professor Elizabeth Loftus that memory, an aspect of every individual which many believe as infallible, is actually fallible. In fact, the memory of a human being can be manipulated or limited, either intentionally or unintentionally, through various ways. This can cause problems as small as a family disagreement, remembering you were somewhere you never were, or even a failure to accurately recall a special event; however, it can also affect the reputation and sometimes…

    An accepted presumption of memory is that every little thing is stored, that given the right recovery prompt or method, a memory will be "unlocked" and will relayed accurately (Robinson-Riegler &Robinson-Riegler, 2012). When an individual want to know something that happened in their past they should request that they are cognitively questioned by their psychotherapist. A cognitive questioning means that there cannot be any questions that are leading and that the individual is as comfortable as possible prior to being questioned. The technique is to not jump to conclusions and produce your own scenarios within your mind about what could have taken place, but additionally about what you do recollect the events that surround the incident that took place. "Deceptive information presented after an event can lead people to erroneous reports of that misinformation. Different process histories can be responsible for the same erroneous accounts in different individuals" (Loftus & Hoffman, 1989). There have individuals have gone through with hypnosis and have been on rigorous medication regimens because they are afraid of the affects of what they will do on their memory. When an individual has a good relationship with other people that they grow up with or if the people watched the individual watched grow up can help keep the memories stay alive. The problem with this is that the person has to whole heartedly trust the people to remember the accuracy, which sometimes can be tricky. "Misleading information presentation after an event can lead people to erroneous reports of that misinformation. Different process histories can be responsible for the same erroneous report in different people" (Loftus & Hoffman,…

    It occurs when a person’s recall of episodic memories becomes less accurate because of post-event information. Research in this area began by Elizabeth Loftus in 1974. It was about the “ False Memories”. When the first collection of misinformation experiments appeared in the mid-1970s, the lesson that was being learned from these experiments was that misleading postevent information can impair memory of an original event ( Loftus, 1975 , 1977 , 1979 ). Memory Impairment Hypothesis- a genuine change or alteration in memory of an experienced event as a function of some later event. McClosky and Zaragoza ( 1985 a, 1985 b) disputed the memory impairment hypothesis. McCloskey and Zaragoza (1985), claimed that memory for an original event is not impaired by misleading postevent information. McCloskey and Zaragoza devised a test that excluded the misinformation as a possible response alternative, and they found no misinformation effect. McCloskey and Zaragoza argued that it was not necessary to assume any memory impairment at all–neither impairment of traces nor impairment of access. According to Johnson and Lindsay (1986) Source Misattribution Hypothesis i.e., source misattribution theory states that an inability to distinguish whether the original event or some later event was the true source of the…

    One of the more fascinating phenomena in Psychology has been the false memory syndrome. False memories gained notoriety in 1960s America, when record levels of therapy patients reported that they had been sexually abused by family members, but were only able to recover these previously suppressed and unrecognized memories of said abuses while in therapy. This led many psychological researchers to conclude that particular psychodynamic practices used by therapists were more than likely the source of these false memories. To support these claims, researchers went on to demonstrate that false memories could be induced in participants using complex paradigms such as paragraphs or simple word list paradigms, as all memory at its…
