How Accurate is an Eyewitness?
Eyewitness testimony is a legal term that allows witnesses to inform us what happened the night of a specific event. This is a necessity for an accurate case, and helps the jury decide the right verdict. Without eyewitness testimony we would not be able to solve cases as easily. With saying this, there are also many things that contemplate whether their information is as precise as they say. There are an abundance of factors that affect the accuracy of eyewitness testimony. “Psychologists usually separate the process of remembering into three stages: Encoding, storage and misinformation effect”(Science) First off, how does the brain store our information? Storage is the more or less passive process of remembering

It is split up into four different types: acoustic encoding, visual encoding, tactical encoding, and semantic encoding. Acoustic encoding is the process of encoding sounds and words of the memory. For instance, let’s say your friend told you there was a test on monday over the phone. Your brain would use your acoustic encoding to send it into your storage. Next, is your visual memory. This is the process of encoding images and visual memory. Like when you study a picture, and have to remember it later. Another type of encoding is your tactile encoding. This is the process of encoding by feeling, usually by touching it. Lastly, is semantic encoding. Which is the process of encoding sensory …show more content…
Well first off is the timing. If the incorrect information is presented after the original information it is more likely to be accessible in your memory. Abling it to be much more easier to retrieve, “effectively blocking the retrieval of the original, correct information.”(“what is misinformation effect”) Another thing that can make it more likely to happen is talking to other witnesses about it. This can distort or change small details of the original memory. The reports given by other witnesses might conflict with your memory. Eye witness testimony is used in many court systems to figure out the correct verdict. “No matter what eyewitness testimony is in the court of law, it is the lowest form of evidence in the court of science.”(“Neil DeGrasse Tyson Quote.”) Although many people in the court believe that this is a very accurate resource, this isn 't always true.In conclusion eyewitness testimony isnt a good or accurate resource for getting the correct verdict in a case, due to the misinformation effect, encoding, and storage in our
Followed by the lack of corroboration, which is an important aspect in courtrooms, “corroboration will add credibility to the memory and lack of it may raise doubts about the allegations.” Loftus considers that relying on memory is not a valid way of justice; the legal system needs to improve when eyewitness testimonials are used in the courts. Loftus confides as a psychologist that psychological science has taught them about human memory and that the research has revealed the limits of human memory. Adding on, these research findings need to be incorporated in procedures to improve the court system. She hopes readers will acknowledge the fact that the use of memories in a trial can be problematic since they are “dangerous” and can lead to false
It is unlikely that social consequences of false memories can be avoided. Elizabeth Loftus was intrigued to study false memories, and is perhaps personally responsible for subsequent developments throughout the history of false memories. Some of this history addresses various theories aimed at isolating how or why false memories occur. These include Source Monitoring Framework, Activation Monitoring Theory, Fuzzy Trace Theory, and strategies for persuasion which can lead to the development of false memory. Such persuasion leads to the present discussion concerning how persuasion in the judicial system has created false confessions and wrongful eyewitness testimonies, due to the Misinformation Effect.
The description of the Lockerbie bombing may provide image on how lengthy and complicated an investigation and a trial process could be. Eyewitness would have to go through repeated interviews. The purpose of this procedure is to assess the consistency and accuracy of the testimony. Unfortunately, it is often not realized that repeated interview may also have a negative effect on the quality of the testimony given. A study by Sharps, Herrera, Dunn, and Alcala investigated the effect of repeated questioning in the format based of police procedure (2012).
From this one can conclude that people are trying to stop false witnesses. This is happening by sending them to jail. Three false witnesses in a murder case received double-digit prison sentences (O’Grady). This shows that people are taking steps to the right path of justice. A more specific example can be Austasia Kapteyn.
As Loftus explains, we are so willing to accept unreliable eyewitness accounts because we do not understand how memory actually works. Most people believe the "video camera" scenario instead of the "evolutionary" scenario. Because of this misconception we are very strongly inclined to believe eyewitness accounts. “Why is eyewitness testimony so powerful and convincing? Because people in general and jurors in particular believe that our memories stamp the facts of our experiences on a permanent, non-erasable tape, like a computer disk or videotape that is write-protected,” (p. 21).
As well a lay person may believe a false eyewitness, believing they would not change what exactly they saw. A follow up study to help with these limitations would be a study that would have a more diverse selection of people. They would be administered one of the three scenarios as well. While the people are viewing the scenario, they will also be taking an exam to depict if they are racist or not or have feelings towards people that are different from them.
what can be done about this? If you are properly trained, Pamela Meyer, author of the best selling book Lie Spotting says that you can improve your lie detection techniques by 25-50% making you are accurate as up to 94% Because the truth is that there’s no such things as an original liar. They all have patterns. What can you do to avoid being lied to?
This week’s topic was very interesting to learn about how important eyewitnesses can be when a crime and accidents do occur. In the case that was presented in the 60-minute segment of Ronald Cotton and Jennifer Thompson is exactly how legal system can fail us when it comes to the eyewitnesses’ identification testimony and how a person’s perception and memory can be altered. The aspect of psychology and law research from this week’s course material is most relevant to the topic of perception and memory. The memory has different stages the first is encoding the process of entering perception into memory.
It’s mind blowing how the justice sentence can convict somebody solely off an eye witness testimony, especially if the eye-witness isn’t accurate. “Eyewitness misidentification is the greatest contributing factor to wrongful convictions proven by DNA testing, playing a role in more than 70% of convictions overturned through DNA testing nationwide.’’ (Eyewitness Misindentification,2017) Immediately after reporting the crime, the victim was taken to a hospital where a rape kit was administered, and swabs were taking from her body. Days after the rape the victim was also shown two photo lineups of suspects, however she didn’t identify anyone.
Furthermore, there can be several factors at play when a wrongful conviction occurs and each case is unique. Three of the more common and detrimental factors that will be explored in this essay are eyewitness error, the use of jailhouse informants and professional and institutional misconduct. Firstly, eyewitness testimony can be a major contributor to a conviction and is an important factor in wrongful conviction (Campbell & Denov, 2016, p. 227). Witness recall and, frankly, the human emory are not as reliable as previously thought. In fact there has been much research showing the problems with eyewitness testimony such as suggestive police interviewing, unconscious transference, and malleability of confidence (Campbell & Denov, 2016, p.227).
Eyewitness identification is ineffective and unjust. Studies have shown that 40% of eyewitness identifications are wrong (Vrij, 1998). Eyewitness identification has great importance in the legal system. This requires the best eyewitness testimony procedure. This essay examines the three main types of eyewitness line-ups; the showup, the sequential and the simultaneous line-up.
If information stored in the short-term memory is not learned and given attention, it will decay over time (Schunk 2012, p. 183). The short-term memory has a small capacity, and large amounts of information cannot all be stored (Schunk 2012, p. 183). To make it esier, information can be shortened or broken up to fit it in the short-term memory (Schunk 2012, p. 183). Information that is used will be transferred into the long-term store/ long-term memory (Schunk 2012, p. 183). There are different strategies to strengthen the memory of information from short-term to long-term.
This clearly sows that the memory is an active process and is expected to alter an opinion based on understanding society (Simple Psychology, 2014) . Eyewitness testimony is unethical as the evidence that is supplied can be provided by someone with stress or anxiety issues this can assist by distraught the image of the suspect. Wrongfully sending an innocent individual to prison. Bloods worth’s case displays it is unethical as there was no psychical evidence nor appearance matched that supported Bloodsworth was responsible for the murder and rape of the victim. Three eyewitnesses were able to identify the perpetrator out of the five and this was based from evidence that he was spotted with the young girl hours earlier before the crime was
, (2003) study. Gabbert investigated the effect of post event discussion on the accuracy of eye witness testimony; where participants
People do this to information by trying to put it in our schemas. Schemas can also question the reliability of eyewitness testimony, as they can cause distortion to memory or unconsciously modify information in order to relate with our current knowledge/ schemas. This can be seen in Bartlett’s study, where participants heard a story and had to recall and tell to another person, like “Chinese Whispers”. Each participant recalled the story in their individual interpretation such as; the passages became shorter, ideas and details of the story were modified. This suggests that each individual person reconstructs our own memories to conform to our personal beliefs about the world.
