Evidence on the reliability of eyewitness testimony is mixed. Applied Cognitive Psychology, 13, 125–144. When an eyewitness stands up in front of the court and describes what happened from her own perspective, this testimony can be extremely compelling—it is hard for those hearing this testimony to take it "with a grain of salt," or otherwise adjust its power. Law and Human Behavior, 28, 687–706. ), Handbook of eyewitness psychology, Vol. These memories can then spill out into other aspects of subjects’ lives, such that they often become less interested in eating that food in the future (Bernstein & Loftus, 2009b). Bernstein, D. M., & Loftus, E. F., (2009a). There are many factors that have been shown to influence eyewitness testimony such as an age bias relating to both the perpetrator and the witness.

One of the most important implications of this fallibility is in the court room, where eyewitness testimony is considered the epitome of evidence. Other studies have shown that misinformation can corrupt memory even more easily when it is encountered in social situations (Gabbert, Memon, Allan, & Wright, 2004). Four of these questions dealt with details that were different in the two versions of the video, so subjects had the chance to influence one another. The subjects were asked to write about each of the four events in a booklet and then were interviewed two separate times.

From the United States Memory Championship to deep within the author's own mind, this is an electrifying work of journalism that reminds us that, in every way that matters, we are the sum of our memories. Another group of researchers photoshopped childhood photographs of their subjects into a hot air balloon picture and then asked the subjects to try to remember and describe their hot air balloon experience (Wade et al., 2002). The disparate research currently being conducted in eyewitness memory in psychology, criminal justice, and legal studies is coherently presented in this work. Volume 1 covers memory for events. Volume 2 cover memory for people. Brigham, J. C., Bennett, L. B., Meissner, C. A., & Mitchell, T. L.

Identification errors occur, and these errors can lead to people being falsely accused and even convicted. Julius Earl Ruffin spent 21 years in jail due to eyewitness' inaccurate memory. Law enforcement and the courts should follow the recommendations of social scientists when using and assessing eyewitness techniques, such as lineups, in criminal cases. (2003). Semantic integration of verbal information into a visual memory. Other false memories implanted with this methodology include having an unpleasant experience with the character Pluto at Disneyland and witnessing physical violence between one’s parents (Berkowitz, Laney, Morris, Garry, & Loftus, 2008; Laney & Loftus, 2008). Psychological science has taught us what some of those precautions might involve, and we discuss some of that science now. Allan, K., & Gabbert, F. (2008). Subjects in one study were more likely to say yes when asked “Did you see the broken headlight?” than when asked “Did you see a broken headlight?” (Loftus, 1975). Some memory errors are so “large” that they almost belong in a class of their own: false memories. After watching the videos, the “co-witnesses” worked together on 12 memory test questions. Identification errors occur, and these errors can lead to people being falsely accused and even convicted. They (like the rest .

Likewise, eyewitness memory can be corrupted by leading questions, misinterpretations of events, conversations with co-witnesses, and their own expectations for what should have happened. Eyewitnesses can provide very compelling legal testimony, but rather than recording experiences flawlessly, their memories are susceptible to a variety of errors and biases. Other important recommendations that have come out of this research include better ways to conduct lineups, “double blind” lineups, unbiased instructions for witnesses, and conducting lineups in a sequential fashion (see Technical Working Group for Eyewitness Evidence, 1999; Wells et al., 1998; Wells & Olson, 2003). In these studies, subjects are told (falsely) that a powerful computer system has analyzed questionnaires that they completed previously and has concluded that they had a particular experience years earlier. Eyewitness testimony can be of great value to the legal system, but decades of research now argues that this testimony is often given far more weight than its accuracy justifies.

Examining these memory distortions can help us better understand normal memory and its reconstructive nature. Garrett, B. L. (2011). For example, one group of researchers used a mock-advertising study, wherein subjects were asked to review (fake) advertisements for Disney vacations, to convince subjects that they had once met the character Bugs Bunny at Disneyland—an impossible false memory because Bugs is a Warner Brothers character (Braun et al., 2002).

In the reading, "Eyewitness Testimony and Memory Bias", Laney and Loftus, supports this thesis by commenting on that people make mistakes in their memories by mixing up details and places across time and "because many aspects of our everyday lives are full of redundancies, our memory systems take advantage of the recurring patterns by . This is obtained by providing case studies to simplify issues in forensic psychology for the legal professional. How to tell if a particular memory is true or false. This phenomenon is called the misinformation effect, because the misinformation that subjects were exposed to after the event (here in the form of a misleading question) apparently contaminates subjects’ memories of what they witnessed. In these cases, witnesses tend to talk to one another in the immediate aftermath of the crime, including as they wait for police to arrive. The formation of false memories.

Eyewitnesses are often asked to describe that perpetrator to law enforcement and later to make identifications from books of mug shots or lineups. A fair lineup is one in which the suspect and each of the foils is equally likely to be chosen by someone who has read an eyewitness description of the perpetrator but who did not actually witness the crime (Brigham, Ready, & Spier, 1990). Then subjects worked individually on 20 additional memory test questions. Research over the last 40 to 50 years has provided extensive insight into the malleability of memory, showing that memory is reconstructive. Caputo, D. D., & Dunning, D. (2007). As the Thomson example illustrates, an eyewitness identification can even outweigh a strong alibi supported by other testimony. These patients’ therapists claimed that the patients were recovering genuine memories of real childhood abuse, buried deep in their minds for years or even decades. Eyewitnesses are often asked to describe that perpetrator to law enforcement and later to make identifications from books of mug shots or lineups. Even slight differences in the wording of a question can lead to misinformation effects. Memory for an event that never actually occurred, implanted by experimental manipulation or other means. Psychonomic Bulletin and Review, 6, 313–138. In some studies, subjects are told they once got sick on a particular food (Bernstein, Laney, Morris, & Loftus, 2005). Sometimes the lineups are target present, meaning that the perpetrator from the mock crime is actually in the lineup, and sometimes they are target absent, meaning that the lineup is made up entirely of foils. Subjects in one study were more likely to say yes when asked “Did you see the broken headlight?” than when asked “Did you see a broken headlight?” (Loftus, 1975). Loftus, E. F., & Pickrell, J. E.

But some experimental psychologists believed that the memories were instead likely to be false—created in therapy. Therefore, a person who has a lower working memory will not have the ability to move information, such as details of a crime into their long-term memory, meaning they may not be able to recall an event that took place awhile before (Jenkins, 2018). For example, it turns out that our expectations and beliefs about how the world works can have huge influences on our memories. A variety of different false memories have been implanted in this way. These researchers then set out to see whether it would indeed be possible for wholly false memories to be created by procedures similar to those used in these patients’ therapy. Washington, DC: American Psychological Association. Four of these questions dealt with details that were different in the two versions of the video, so subjects had the chance to influence one another.
