“Time to Rewrite Your Autobiography?” by Kimberley A. Wade and Cara Laney [P1] Remember that time you went on a hot-air balloon ride at a fair when you were little? You went with your dad – here’s a photo of him! You were worried at first but he reassured you . . . it made you a much more trusting individual. Quite a momentous day. Except it never happened. As strange as it might seem, plenty of psychological research shows that it is possible to plant these kinds of false autobiographical memories, using various techniques. Suggestive interviews [P2] One method for creating wholly false memories involves multiple highly suggestive interviews. In these studies, adults (usually undergraduates but sometimes members of the public) are asked to read descriptions of events that they experienced as children. However, unbeknownst to them, one event is fabricated by the experimenter. [P3] For example, Loftus and Pickrell’s (1995) participants read a fictional story about getting lost in a shopping mall when they were five, and being rescued by an elderly person who reunited them with their family. (The false events in suggestive interview studies are always moderately significant personal experiences that the participants’ family members can verify never happened.) Over two or three sessions, the participants are encouraged to recall their unremembered events, sometimes using techniques that purport to aid memory, such as mentally recreating the physical context of the event. [P4] Once the study is over, independent judges are trained to code transcripts of participants’ memory reports and to determine who reported false memories of the target event. Some studies have differentiated, in various ways, between participants who reported “partial” and “complete” false memories. The gist of the distinction is that participants who provide evidence that they genuinely believe they are remembering the false event (“I remember feeling scared when I couldn’t find my Mom”) and details beyond those that are provided in the false description, are classified as having complete false memories. Participants who merely accept that the event occurred or speculate about it (“Well, it might have happened in the mall down the road from our house”) are classified as having partial false memories. [P5] So how many participants report partial or compete false memories? We calculated that one third of the 560 participants in 10 published studies were scored as having partial or complete false memories. And in the studies that differentiated between partial and complete, 17 per cent were scored as partial and 17 per cent as complete. The highest rate of complete false memories in an individual study was 26 per cent (Porter et al., 1999), but recent studies have modified the suggestive interview procedure and revealed even more dramatic rates of false recall (for a brief review see Wade & Garry, 2005). [P6] In the suggestive interview technique, the act of imagining a counterfactual childhood event presumably causes participants to generate perceptually rich and coherent false details about the suggested event. Over time, these images and thoughts become increasingly like real memories, and participants become confused about what is imagined and what is real. Support for this premise comes from studies that show that the more times people imagine performing an action, the more likely they are to incorrectly claim that they actually did perform it (Goff & Roediger, 1998). Suggestive interviews and props [P7]Recently, one team of false-memory researchers extended the suggestive interview technique to include props, specifically childhood photographs (Lindsay et al., 2004). Trauma-oriented psychotherapists sometimes encourage clients to peruse photographs to help cue longforgotten memories of upsetting experiences. Lindsay and colleagues predicted that personal photographs, when combined with suggestive interview techniques, might foster the creation of false memories. The researchers were right. They asked some adults to try to remember three childhood events; as usual, one event was false, describing how the participant was reprimanded at school for sneaking Slime (the gooey green toy) into their teacher’s desk. All of the participants heard descriptions of the Slime event, but half also received a class-group photo from the relevant school year. Of those subjects who did not receive the class photo, 23 per cent formed false memories of the Slime event. But with the aid of a photograph, the false-memory rate soared to 65 per cent. [P8] The ‘Slime event’ differs dramatically from the types of events clients recall in therapy. Yet these findings warrant concern about the riskiness of encouraging people to review photographs during attempts to cue suspected but forgotten memories of childhood trauma. Indeed, there are good reasons to believe that the mechanisms responsible for false memories in the laboratory may also contribute to other types of false memories (Wade et al., 2007). [P9] A series of related studies have used digitally altered photographs to implant false childhood memories (Garry & Wade, 2005; Wade et al., 2002). They showed some adults three real childhood photos, and one fake photo depicting the participant taking a hot-air balloon ride as a child (Figure 1). Hot-air ballooning was chosen because it is a moderately significant personal experience that typically requires parental consent; thus, family members could verify it never happened. Participants considered their set of childhood photos and tried to remember the depicted events in three sessions over a maximum of two weeks, and by the end of the study, 50 per cent remembered something about the hot-air balloon ride. The false-memory reports were often rich with detail. One participant said: I’m still pretty certain it occurred when I was in Year 6 at the local school – basically for $10 or something you could go up in a hot-air balloon and go up about 20-odd meters. It would have been a Saturday and I think we went with, yeah, parents and, no it wasn’t, not my grandmother. I’m not certain who any of the other people are there. I’m pretty certain that Mom is down on the ground taking a photo. [P10] These studies show that a doctored photograph, without any accompanying verbal description, is enough to lead people to report entirely false memories of significant childhood events (Garry & Gerrie, 2005 provide a comprehensive review of how photographs affect memory). But a new study by Nash and Wade (2007) shows how powerful false evidence can really be. [P11] Significant advances in digital technology mean that fake video evidence can be highly compelling and almost impossible to refute. This led Nash and Wade (2007) to examine whether tampered video evidence could lead people to believe they committed an act they never did: cheat on a psychological experiment. [P12] The experimenters filmed participants carrying out a computerized gambling task. The task required participants to answer a series of general knowledge multiple-choice questions and to bet (fake) money on their answers every time they responded to a question. When they answered a question correctly a green tick appeared on the monitor and they were instructed to collect money from the ‘bank’, whereas when they answered a question incorrectly a red cross appeared on the monitoring and they were instructed to return money to the bank. Two hours later participants returned to the lab and the experimenter accused them of taking money once (Experiment 1) or three times (Experiment 2) in the first session when they should have returned it. In addition, the participants were told that their data could no longer be used and that they would have to forfeit payment for taking part in the study. Half of the participants were told that incriminating video evidence existed, and half were exposed to a doctored video that depicted them committing the act (a green tick was digitally replaced with a red cross so that the participant was apparently taking money from the bank when an error message appeared). [P13] In two studies, almost all of participants who viewed the fake video falsely confessed to the act. Over 70 per cent told a research confederate that they had made the mistake, indicating that they genuinely believed the false act occurred. [P14] This is the first study to demonstrate the dangers of modern digitalmanipulation technology when encouraging people to remember recent autobiographical experiences. This study also mimics real-world situations that may lead to false memories. For instance, police interrogators can and do lie about the existence of evidence during interrogations and this oft-used tactic is legal in the United States (Kassin & Gudjonsson, 2004). Social influence [P15] We have shown how direct suggestive methods can play havoc with memory. But a less direct method, and a relatively new area of research in the false autobiographical memory domain, is the role of social influence in creating false memories. [P16] Discussion is an integral part of our lives. We reminisce with family members about shared experiences and attempt to agree on what ‘really’ happened (Ross, 1997). When we witness surprising or spectacular events we talk to other witnesses and consider whether our versions of events match up. These discussions in the name of accuracy testing can have serious implications for eyewitness memory (see Gabbert et al., 2003). But can discussion like this influence autobiographical memory? French et al. (2006) showed that it can. The experimenters used an internet-based version of the suggestive interview technique to examine how discussion influenced both genuine and false memories for childhood events. Pairs of adult siblings attempted to recall some real childhood events plus a fake childhood event, which was a hot-air balloon ride. At first, the siblings recalled the events independently, but then they discussed their memories with each other (using the online learning environment Blackboard) before reporting, independently once again, what they could remember. The results showed that participants incorporated snippets from each other’s real and false memories into their own recollections; and, although almost 25 per cent of participants reported false memories, the false-memory rate dropped dramatically after participants discussed their memories. One explanation for this drop could be that skeptical participants – those who doubted the authenticity of the false event – pressed their siblings to carefully consider the true source of their memories. As a result, participants became more conservative when accepting and reporting images and thoughts as genuine experiences. Conclusions [P17] If memory is the diary we carry about, then it is likely to include truths, half-truths, gaps and falsities. We have shown that memory can be inexact and unreliable – various suggestive techniques can lead to wholly false memories for personal experiences. We hasten to add, however, that substantial errors in memory, and completely false memories, also occur in real life, far outside of the laboratory (see Schacter, 2001). In fact, it is very likely that everyone reading this article has a collection of false autobiographical memories that they are completely unaware of. [P18] Like true memories, false memories can be held with great confidence, can be detailed, can be vivid, can have behavioral consequences, and can even be emotionally rich. But the fact that a particular memory is confidently held, detailed, vivid, consequential or emotional, or even all of these, cannot guarantee that the memory is real.

Include a QUOTE from the article in your answer. 7) Why would these experiments be important to someone working as a lawyer or counselor or therapist? 8) Paraphrase the first two sentences of P16. IDEAS FOR AN ESSAY: ==A) The act of memory seems simple enough, doesn’t it? So try to answer a few simple memory exercises. Who were the last three people you spoke to or texted? What did you eat at each meal yesterday? What were the last few songs you listened to? What are the birthdays of your family members? Who were the last three people to arrive in class today? Can you name your teachers from last semester--or this one? (If these are too easy, then think of your own tests...) What was easy or difficult about remembering these things? How complete were your answers? Why might that matter? ==B) All families seem to have “family stories,” some of which are told again and again--and often in different versions! What is an important “memory” of your family’s past, and what might make you or other people wonder about how true it really is? (A more difficult version of this is to learn that a crucial memory that you have held for so long was actually just a fiction that others told you...) ==C) Consider some of the professions that you might prepare for during college: education, psychology, sociology, business, medicine, law. How does the research that you’ve just read about relate to any of these fields? Why and how is memory so important to us, and what can go wrong if we make decisions based upon memories that may be incomplete or false? ==D) In his autobiography, Barack Obama openly admits that he was fascinated by any story about his missing father--and he also admits he wasn’t quite sure if he could believe some of these stories. He refers to his father as a “myth.” What can that word mean, and why are myths so common among many different groups of people? Who else do we form “myths” about? ANSWER KEY ==1) In these studies, people were asked to recall all of the following events except: A) Sneaking some Slime into a teacher’s desk B) Getting separated from their family during a shopping trip C) Visiting a close relative during the holidays<< D) Going on a hot-air balloon ride This one is very easy if you take the time to review the whole essay! ==2) Which type of evidence is NOT used in this article? A) Summaries of experiments B) Statements from the participants in the experiments C) Statistics about the experiments D) Individual case studies of participants in these experiments<< The article obviously features A) and C). There are brief statements from the participants in P4 and P9, but there is no detailed sort of “case study.” ==3) After reading this article, one may infer that this research on memory would be of interest to: A) A lawyer defending someone who confessed to a crime B) An adult who believes that he was mistreated as a child C) A counselor trying to help a client discuss a childhood trauma D) A judge trying to decide on the reliability of a witness’s statement E) All of the above<< P14 and P16 clearly point to potential conflicts in legal settings. P6 and P7 point to the difficulty of establishing reliable narratives of childhood events. ==4) The tone of the opening paragraph is: A) Condescending B) Understanding<< C) Sarcastic D) Hostile Claims of “false memories” are sometimes the source of heated debates. In this case, the revelation that a wonderful family memory “never happened” is not met with disdain. Instead, the second part of the paragraph states that such false memories are both common and explainable. ==5) The purpose of P4 is to: A) Clarify some of the key terms used for these memory experiments<< B) Challenge the integrity of the people in the experiments C) Quantify the number of people providing certain types of memories D) Argue that certain groups of people are more likely to offer false memories The paragraph surely does not do either B) or D). C) is tempting--but this happens in the next paragraph. The repetition of the terms “partial” and “complete” should make this answer easy. ==6) The main idea of P7 is that: A) Photographs are real documents, so they help a person recall real events B) Photographs frequently lead people to misremember their own pasts C) Photographs when combined with suggestive comments can lead to false memories D) Photographs can be used to help vulnerable children recall childhood traumas The paragraph makes it clear that we would like to believe A) and D). Yet it warns that this might get complicated. Answer B) is plausible, but the key distinction made in this section is that photos paired with props or suggestions strongly influence memory. ==7) In P12, the word “incriminating evidence” most closely means something that: A) Proves innocence B) Proves guilt<< C) Causes controversy D) Creates embarrassment The paragraph mentions that participants had been “accused” and then had to “forfeit” their gains. This should help cue you to the issue of guilt or innocence. ==8) Which type of organization is used most often in P16?: A) Personal narrative B) Argument C) Cause and effect<< D) Definition There is no personal narrative here, nor any sustained definition. There is some argument, but most of the paragraph is explaining how different social interactions might cause different memories to form. ==9) See P16. Based on this paragraph, after people share their memories of an event, they are: A) More likely to re-create a false memory B) More likely to recognize a false memory<< C) More likely to insist that their own version is correct D) More likely to become very confused about the memory The paragraph points out that people will still create some false memories, but that this rate drops “dramatically” after discussion. Rather than being stubborn when faced with questions, they became more “conservative” about questionable information. ==10) What is the most accurate way to re-phrase P17? A) False memories can be caused by certain techniques, yet we can learn to how to completely avoid them. B) False memories are not just caused by techniques in an experiment, and almost everyone has false memories that they do not know about.<< C) False memories are common in the lab and in life, and this creates major problems for people in their daily lives. D) False memories are now better understood, so most people can now recognize the false memories in their own lives. There are two key issues in this paragraph. False memories are created in both experiments AND real life--AND people are usually unaware of their own false memories. C) might be right, but no evidence is provided to support that assumptions.
