Shining A Light On Eyewitnesses

Eyewitness evidence has always been considering critical information when it comes to court trials and convictions. But how reliable are eyewitnesses? Scientific research has shown that eyewitness’s memories are often not accurate or reliable. Human memory is very malleable and is easily changed by suggestion. Relying on eyewitness evidence instead of scientific data often leads to wrongful convictions. Scientific evidence is much more reliable, and should be more important in court cases than eyewitness evidence.

Cognitive Psychology draws the comparison between the human mind and a computer, suggesting that we like the computer process the information we acquire from around us and then react accordingly. Hearnshaw, (1987), claims that Cognitive Psychology is both one of the oldest and also one of the newest parts of Psychology, cited in ?T. Malim?, (1994). Information is collected through our senses i.e. vision, touch, smell etc and then processed through our

Eyewitness testimony has long been viewed as important evidence in court cases. The general population believes eyewitness identification more than any other evidence, even if the witness account is conflicting with the other evidence presented. Studies show that eyewitness testimony is unreliable, and yet it is still considered the most important form of evidence. People think that if a person says they saw something then it must have happened. Currently there are no universal guidelines on how to obtain and present such evidence. The purpose of this paper is to explain why eyewitness testimony is unreliable, and discuss the proposed guidelines on how law enforcement agencies should gather identifications, as well how

Eyewitness testimonies are based on a person’s ability to recall what took place accurately. Memory research has proven that a person’s memory is not a recording but it is reconstructive. Loftus and Palmer’s study set out to prove that the memory could be reconstructed through the use of language.

The human mind is not like a tape recorder obviously, it does not record events exactly as seen in the moment of a crime, and neither can the events be recalled precisely like a tape that can rewind back in time. Therefore, making eyewitness identification inaccurate. For example, in the case of a

The reliability if an eyewitness testimony is questionable. The witness may be so certain that the person that thy are pointing out is one hundred per cent the suspect or they could be so certain when it comes to retelling the incident, although these people are so sure on what it is they are doing, their testimony cannot always accurate. Due to the lack of accuracy with eyewitness

An eyewitness testimony is unreliable because of many different things. Sometimes when witnesses see something they don’t see the whole crime, but only parts which could cause the wrong people to be in trouble. When it’s a serious crime the trial could take years and when asked to stand trial against the perpetrator the witness’s memory could not be fully correct anymore. You could forget important things or get mixed up with things you’ve seen somewhere else, like in a movie. Another reason they are unreliable is Because individuals with certain psychological disorders, like antisocial personality disorder and substance dependence, are at high risk for criminal involvement, they are also at high risk for false identifications by eyewitnesses.

Information is the lifeblood of a criminal investigation. The ability of investigators to obtain useful and accurate information from eyewitnesses of crimes is crucial to effective law enforcement, yet full and accurate recall is difficult to achieve (Stewart, 1985). Such elicitation of complete and accurate recall from people is important in many aspects of life; specifically, eyewitness recall may determine whether a case is solved. Principle advocates of the cognitive interview (Fisher, Geiselman, Holland & MacKinnon,

There has been considerable interest and study in the accuracy or inaccuracy of the use of eyewitness testimonies in the current criminal justice system. Results collated by several studies add to the bulk of literature suggesting that the current usage of eyewitness testimony by the legal system is far from ideal. Currently, high emphasis is being placed on reviewing and reconsidering eyewitness accounts (Leinfelt, 2004). In particular, recent DNA exoneration cases have substantiated the warnings of eyewitness identification researchers by showing that mistaken eyewitness identification was the largest single factor contributing to the conviction of innocent people (Wells & Olson, 2003). In this essay, the use of eyewitness testimony in the criminal justice system will be explored, with a particular focus on the impreciseness of this practice.

The human mind is not like a tape recorder obviously, it does not record events exactly as seen in the moment of a crime, and neither can the events be recalled precisely like a tape that can rewind back in time. Therefore, making eyewitness identification inaccurate. For example, in the case of a

There are many different factors that play a part in the increased chance of a witness correctly identifying a suspect. Such factors should be brought to the attention of the jury and the judge to help in properly assessing whether a witness is correctly identifying a suspect. A study by Magnussen, Melinder, Stridbeck, & Raja (2010) found that of the three different types of people: judge, jury, and general public, that for the most part all where fairly ill-informed on the reliability of eyewitness testimony with judges having the most. Judges only had about an 8% difference in knowledge when compared to jurors. With this information it is very clear that education on the reliability of eyewitness testimony needs to become more of a general knowledge information for the everyone, especially people who are involved in upholding the law. Another factor to look into when evaluating the accuracy eyewitness testimony is the role that memory plays. Memory is divided into three processes: perceiving, remembering, and recalling information (Simmonsen, 2013). There is plenty of room in all three of those stages to forget or falsely remember something. Some factors that play a part when a person perceives an event is the amount of time they are exposed to the event and the suspect. A study conducted by Horry, Halford, Brewer, Milne, & Bull. (2014) found that witnesses were increasingly more likely to correctly identify a suspect if they had been exposed to the suspect for sixty

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.

“How accurate are the memories that we know is true, that we believe in?” (Fraser 2012). The video, “Why eyewitnesses get it wrong” by Scott Fraser, a TED talks filmed September 2012. Fraser explains how and why eyewitnesses can get it wrong. He starts his speech describing a drive by shooting that happened in California. Then describing the process of the eyewitnesses and trial. In this trial, all the eyewitnesses stated that Carrillo, the “shooter”, was the shooter. Even though Carrillo had said he was innocent, after 21years the court decided to have a retrial. In this retrial they hired Fraser to also help with the investigation. Fraser then explained how he had gone though the case materials and found that “all the teenagers … could

Cognitive psychology is an important field because it studies everything that makes up who a person is, based on what they know, think, and feel (Cognition, pg. 3). Understanding cognitive psychology can help people make better decisions and help recognize how people accomplish great things (Cognition, pg. 4). For example, if a person is having a hard time focusing in class and they discover when the chatty people behind them do not show up they take better notes, than it is beneficial for them to cognitively decide to sit somewhere else. This example shows how understanding cognitive psychology can allow someone to get to know himself or herself better, therefore making better personal decisions. Getting a basic understanding of cognitive psychology involves four fundamental concepts: the intrinsic limitations of introspection and behaviorism, working memory, the role of the amygdala, and the structure of a neuron and synapse.

“Cognitive psychology is a modern approach to the study of [processes by which people come to understand the world- such processes as memory, learning, comprehending language, problem solving, and creativity. Cognitive psychology has been influenced by developments in language, computer science, and of course, earlier work in philosophy and psychology” – Hayes (cited by Lundin)
