Accuracy of an Eyewitness Testimony Essay

There are a number of factors can reduce the accuracy of eyewitness identifications for example; extreme witness stress at the crime scene or during the identification process, presence of weapons at the crime; because they can

Psychological research shows that eyewitness testimony is not always accurate; therefore it should not be used in the criminal justice system. Discuss.

Forensic evidence has been shown to be reliable due to many factors of evidence such as DNA, blood, fingerprints, etc.; however, many cases have shown that

In the late 19th-century research on eyewitness, testimony memory began, psychologists had been studying memory, and the findings became useful for forensic psychology and law. A central issue with studying eyewitness memory and testimony is the ecological validity of lab studies. There are relatively few ‘real world’ eyewitness memory studies, and that causes problems for determining the generalizability of findings in eyewitness memory. Coined by Wells (1978) estimator variables are present at the time of a crime and cannot be changed (i.e. witness characteristics and the type of offence) and system variables are factors that can be manipulated to affect eyewitness accuracy (i.e. line-up procedures and interview types). The system variables

First, the human memory does not record all information like a video recorder. Mistaken eyewitness testimony is one of the major causes of wrong conviction. Events of crimes, will have so much stress or focus on a weapon, than the face of criminal (Wrongful Convictions , n.d.). The victim’s or eyewitness’s memory can be changed with an easy simple suggestion. Police procedure dealing with key witnesses by a “show up”. This is showing the suspect in a physical or a picture line up. The confidence of accuracy of identification and exhibited by the witness is a “crucial determinant of believability” by jurors (Furman, 2003). The best result of eyewitness testimony is taken identification immediately. The

There are many factors to consider when psychologists and scientists are trying to figure out reliability of eyewitness testimony. The ability to recall or

Have you ever been a witness to a crime? Would you feel comfortable if prosecutors relied on your eye witness testimony alone for a conviction? According to “The Magic of the Mind”, eyewitness testimony which relies on the accuracy of human memory, has an enormous impact on the outcome of a trial. Eyewitness testimony is a legal term. During an eyewitness testimony, the witness usually goes into an account of the crime he or she has witnessed. This can include details of the crime or identification of perpetrators. Eyewitness testimony is an important area of research in cognitive psychology and human memory (simplypsychology.com). Eyewitness testimony can be affected by many psychological factors such as:

The article, When I Witnesses Talk, covers the issue of eyewitness testimonies and their reliability with memory conformity. Often when two people experience the same event they both have very different recollections of the occurrence. One event within the journal article incorporates the murder of Jill Dando, within this investigation there was a lineup where 16 witnesses were asked to identify the suspect, where only 1 of the 16 witnesses recognized him. The police conducted a second lineup where for example one witness stated that they were 95% sure that the suspect that they identified was at the scene of the crime, yet in the original lineup that person was unable to identify anyone from the lineup. One key piece of information was discovered,

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 testimonies are often unreliable and yet they are usually the most incriminating "evidence" provided in court. Eyewitnesses are often under a large amount of stress in the moment and are unable to gather all of the necessary information to accurately describe a crime. The setting of the crime, the type of event occurring, the amount of activity taking place, and the emotional state of the eyewitness can all affect and alter the testimony of the eyewitness. According to the Innocence Project, inaccurate eyewitness testimony accouted for 87% of wrongful convictions. One of these convictions was that of Ronald Cotton.

Yet, according to a meta-analysis by Bernard Whitley (2001), even when the eyewitness is discredited, the defendant will still more likely be convicted as guilty. However, a discredited witness is not seen more reliable than or as reliable as a credited witness. Also, if a witness is confident, then that will also affect a juror’s decision on the defendant.

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.

Eyewitness psychologists play a vital role in identifying the mistakes of eyewitnesses and trying to diminish the error.

Juries tend to pay close attention to eyewitness testimony and generally find it a reliable source of information. However, research into this area has found that eyewitness testimony can be affected by many psychological factors.

This is not always obvious because a witness's statement can seem accurate except for a single variance with the physical evidence. This can be important because of the case were to go to trial, a simple discrepancy in the testimony could be exploited by the opposing attorney. Although it is normal for eyewitness testimony not to be perfect, if there is a difference between the witness's account and a particular piece of evidence, there is a chance that some or all of the testimony has been derived from the statement of one of the parties in the lawsuit or criminal case.
