Eyewitness testimony has long been prized as the highest form of evidence in a courtroom, placing enormous value on the memory of a witness. After all, if someone has observed a crime, the details must be engrained in their memory, right? Well, not exactly. Unlike a fixed and pristine record of time, memory is a complex cognitive process which is not only determined by variables surrounding the actual event, but is also heavily influenced by the perceptions, interpretations, and emotions of the individual (Zaragoza & Mitchell, 1996). In fact, evidence suggests that the simple act of retelling a story alters the original memory, and that the power of suggestion can lead people to not only change the details of an incident, but in many cases, …show more content…
Such influences contribute to a witnesses’ natural tendency to confuse the details suggested with those which were truly witnessed, thus creating false memories (Zaragoza & Mitchell, 1996). In a study conducted by Zaragoza & Mitchell (1996), subjects watched a 5-minute video of a burglary followed by a car chase. A post event questionnaire containing several misleading, and suggestive details followed, and delayed in intervals of 10 minutes, 48 hours, or 1 week (Zaragoza & Mitchell, 1996). Exposure to suggestive material occurred from 0 to 3 times per participant, determining if repetition increased participants’ association of suggested material as being originally viewed in the film (Zaragoza & Mitchell, 1996). To address concerns that participants may have failed to differentiate between events they thought happened in the film, and the events which did occur in the film, an additional 5-question survey consisting of yes and no questions was administered (Zaragoza & Mitchell, 1996). Indeed, evaluation confirmed that the percentage of “yes” responses was far greater for three exposures than for one, and that repetition generated a significant increase in the participants’ confidence of association errors (Zaragoza & Mitchell, 1996). In other words, increased repetition led participants to not …show more content…
However, this time the slides ended right before a critical event occurred. Participants were then questioned, not only about the content of the missing slide, but also as to its source (slide material or narrations). Bi Zhu, Chuasheng, & Lotfus (2012) provided a ten-minute delay before the source monitoring test, which mirrored the content, and procedure of the initial study. As expected, false memory was identified 1.5 years after the initial exposure of misinformation, with about half of false memory being preserved between the 2 studies (Bi Zhu, Chuasheng, & Lotfus, 2012). This showed that the longevity of false memory is proportional to the rate of true memory (Bi Zhu, Chuasheng, & Lotfus, 2012). In other words, true and false memories do in fact decay at similar rates, and once an individual has a new memory, that memory will persist despite the
The use of eyewitness statements and testimony’s can be a great source of information, but can also lead to wrongful convictions. Due to eyewitness testimony, innocent people are convicted of crimes they have not committed. This is why the wording of a question is important to consider when interviewing witnesses. Due to the fact that eyewitness testimony can be the most concrete evidence in an investigation, witnesses may feel they are helping an officer by giving them as much information as possible, therefore they may tell them information that is not entirely true, just to please them. This is why there are advantages and disadvantages to using open and close ended questioning at different durations of an interview. The way you word a question may impact the memory of a witness, this is because a person cannot completely memorize the exact occurrences of an event.
The use of eyewitnesses has been a constant in of criminal justice system since its very beginning. Unfortunately, people do not make the best witnesses to a crime. The person may not have seen the actual criminal, but someone that looks similar to them. The witness may lie about what he or she may have scene. Also the witness can be influenced by the police as to who or what they saw at the time of the crime. The witness or victims memory of the person may have faded so that they don’t remember exactly what had seen, which could be disastrous for the accused.
In the magic of the mind author Dr. Elizabeth loftus explains how a witness’s perception of an accident or crime is not always correct because people's memories are often imperfect. “Are we aware of our minds distortions of our past experiences? In most cases, the answer is no.” our minds can change the way we remember what we have seen or heard without realizing it uncertain witnesses “often identify the person who best matches recollection
During the identification and prosecution of a suspect, eyewitnesses are the most important. Eyewitness testimony needs to be reliable as it can have serious implications to the perceived guilt or innocence of a defendant. Unfortunately, the reliability of eyewitness testimony is questionable because there is a high number of eyewitness misidentification. Rattner (1988) studied 205 cases and concluded that eyewitness misidentification was the factor most often associated with wrongful conviction (52%). Eyewitness testimony can be affected by many factors. A substantial literature demonstrates own group biases in eyewitness testimony. For example, the own-race bias, in which people are better at recognizing faces of their own race versus another
Eyewitness identification and testimony play a huge role in the criminal justice system today, but skepticism of eyewitnesses has been growing. Forensic evidence has been used to undermine the reliability of eyewitness testimony, and the leading cause of false convictions in the United States is due to misidentifications by eyewitnesses. The role of eyewitness testimony in producing false confessions and the factors that contribute to the unreliability of these eyewitness testimonies are sending innocent people to prison, and changes are being made in order to reform these faulty identification procedures.

Elizabeth Loftus, is a psychologist, mainly concerned with how subsequent information can affect an eyewitness’s testimony. Loftus has focused on misleading information in both the difference in wording of questions and how these questions can influence eyewitness testimony. This research is important because frequently, eyewitness testimony is a crucial element in criminal proceedings. Throughout Loftus’s career she has found a witness’s memory is highly flexible and subject to being influenced. The classic study by Loftus and Palmer (1974), illustrates that eyewitness testimony can be influenced by leading questions and ultimately proved unreliable.

In the court of law, eyewitnesses are expected to present evidence based upon information they acquired visually. However, due to memory processing, presenting this information accurately is not always possible. This paper will discuss the reliability of eyewitness testimony, its use in a relevant court case, and how the reasonable person standard relates to eyewitness testimony.
In recent years, the use of eyewitness testimonies as evidence in court cases has been a subject in which various researchers have been interested in. Research suggests that eyewitness testimonies are actually not reliable enough to use as primary evidence in court cases. There have been many cases in which an innocent person gets sent to prison for a crime they did not commit because an eyewitness testified that they were the ones that they saw at the scene of the crime. Researchers’ goal is to improve the legal system by finding out whether eyewitness testimonies should be used in the court of law or not.
During the identification and prosecution of a suspect, eyewitnesses are of the utmost importance. They provide crucial information that determines the fate of the criminal, whether their memories are true to the event or slightly altered. Many eyewitnesses, being the victims of these crimes, have strong emotions related to the event. It has been found that emotions play a role in the accuracy and completeness of memories, especially in eyewitness testimony (Huston, Clifford, Phillips, & Memon, 2013). When emotions are negative in content, accuracy increases for memory of an event (Storbeck & Clore, 2005; Block, Greenberg, & Goodman, 2009). This finding holds true for all types of eyewitnesses, including children. There is no difference in memory between children and adults for aversive events, suggesting that the child eyewitness is just as capable as the adult eyewitness to give an accurate testimony (Cordon, Melinder, Goodman, & Edelstein, 2012). For my research paper, I will focus on the role of emotion in children’s eyewitness testimony.
Have you ever been an eyewitness at the scene of a crime? If you were, do you think that you would be able to accurately describe, in precise detail, everything that happened and remember distinct features of the suspect? Many people believe that yes they would be able to remember anything from the events that would happen and the different features of the suspect. Some people, in fact, are so sure of themselves after witnessing an event such as this that they are able to testify that what they think they saw was indeed what they saw. However, using an eyewitness as a source of evidence can be risky and is rarely 100% accurate. This can be proven by the theory of the possibility of false memory formation and the question of whether or not a memory can lie.

People fail to notice when they are presented with something different from what they originally chose and tend to come up with explanations as to why they picked that specific choice. In this research paper, Cochran, Greenspan, Bogart, and Loftus discuss how choice blindness can lead to distorted eyewitness memories. In their experiment, the studied if the participants in their research realized modifications to their memory reports and if these changes could possibly effect the participants’ memory. Cochran, Greenspan, Bogart, and Loftus conducted two different experiments. Experiment 1 was constructed on two self-sourced vs. other-sourced between participants and two misinformation vs. control within participants. They had participants watch a slideshow that showed a woman intermingling with three other characters and one of them steals her wallet. Then they completed a personality measure in 15 minute retention interval which was followed by questions about their memories from the slideshow. After, they were given another 15 minute retention interval and then shown their responses to the memory question, but three of their responses were revised. According to Cochran, Greenspan, Bogart, and Loftus (2016), “experiment 1 demonstrated that when witnesses were exposed to altered versions of their own memory reports for episodic details of an event, their memories changed to be consistent with
Loftus has focused the bulk of her career on both the psychological and legal aspects of distorted or false memories, and her work demonstrates the facility with which memories and beliefs can be molded. Her findings regarding the strength of eyewitness testimony and repressed traumatic memories have helped change the notion that such testimony is absolutely reliable (Zagorski, N., 2005).”
