Recommended: Determinants of accuracy in memory
Psychologist Elizabeth Loftus’ main focus in the 1975 journal article, “Leading Questions and the Eyewitness Report”, was on the influence of leading/misleading information in terms of both visual imagery and wording of questions in relation to eyewitness testimony. The problem that she investigated was that the questions asked about an event shortly after it occurs may distort the witness’ memory for that event. The research hypothesis was that the wording of questions asked immediately after an event may influence responses to questions asked considerably later and when the initial question contains either true or false presuppositions, the likelihood is increased that subjects will later report having seen the presupposed object.

The author analyzed the data by the misinformation effect paradigm, which demonstrated that the memories of eyewitnesses are altered after being exposed to incorrect information about an event - through leading questions or other forms of post-event information; and that memory is highly malleable and open to suggestion. The misinformation effect became one of the most influential and widely known effects in psychology, and Loftus’ early work on the effect generated hundreds of follow-up studies examining factors that improve or worsen the accuracy of memories, and to explore the cognitive mechanisms underlying the …show more content…
This transition can take place because of the inherent importance of the information or as a result of repeated use or intentional repetition. Fortunately, long-term memory does not have the same limits that short-term memory does. The human brain appears to be able to hold an unlimited number of long-term memories for an indefinite amount of time.
Eyewitness testimony is an important area of research in cognitive psychology and human memory. The use of eye-witness testimony is often a primary source of evidence used in the judicial system. When there is no evidence to apprehend the accused, eye-witness testimony becomes an effective tool in apprehending the culprit. Juries tend to pay close attention to eyewitness testimony and generally find it a reliable source of information even when research into this area has found that eyewitness testimony can sometimes be
This paper will consider eye witness testimony and its place in convicting accused criminals. Psychology online (2013) defines “eye witness testimony” as a statement from a person who has witnessed a crime, and is capable of communicating what they have seen, to a court of law under oath. Eye witness testimonies are used to convict accused criminals due to the first hand nature of the eye witnesses’ observations. There are however many faults within this system of identification. Characteristics of the crime is the first issue that will be discussed in this paper, and the flaws that have been identified. The second issue to be discussed will be the stress impact and the inability to correctly identify the accused in a violent or weapon focused crime. The third issue to be discussed is inter racial identification and the problems faced when this becomes a prominent issue. The fourth issue will be time lapse, meaning, the time between the crime and the eye witness making a statement and how the memory can be misconstrued in this time frame. To follow this will be the issue of how much trust jurors-who have no legal training-put on to the eye witness testimony, which may be faltered. This paper references the works of primarily Wells and Olsen (2003) and Rodin (1987) and Schmechel et al. (2006) it will be argued that eye witness testimony is not always accurate, due to many features; inter racial identification, characteristics of the crime, response latency, and line up procedures therefore this paper will confirm that eyewitness testimonies should not be utilised in the criminal ju...
(Kennedy & Haygood, 1992; Williams & Loftus, 1994), which is worrying considering the growing and substantial body of evidence from laboratory studies, field studies, and the criminal justice system supporting the conclusion that eyewitnesses frequently make mistakes (Cutler & Penrod, 1995; Huff, 1987; Huff, Rattner, & Sagarin, 1986; Innocence Project, 2009; Wells, Small, Penrod, Malpass, Fulero, & Brimacombe, 1998). According to a number of studies, eyewitness misidentifications are the most common cause of wrongful convictions (Huff, Rattner, & Sagarin, 1986; Wells et al., 1998; Yarmey, 2003) and, through the use of forensic DNA testing, have been found to account for more convictions of innocent individuals than all other factors combined (Innocence Project, 2009; Wells, Memon, & Penrod, 2006).
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.
The justice system depends on eyewitness evidence to convict offenders. Eyewitness is a difficult task to achieve in the justice system. According to Wise, Dauphinais, & Safer (2007), in 2002 one million offenders were convicted as felons in America. Out of those one million offenders, 5000 of them were innocent in 2002 (Dauphinais, 2007). The Ohio Criminal Justice survey states that 1 out of 200 felony criminal cases is a wrongful conviction (Dauphinais et al., 2007). According to Dauphinais et al., (2007), Dripps said that eyewitness error is a huge factor in cases of wrong convictions. A study conducted in 1987 indicated that in roughly 80,000 criminal cases, eyewitness error was the only sole evidence against the defendant
Eyewitnesses are primarily used by the criminal justice system for investigating and prosecuting crimes, particularly in circumstances where it is the only evidence available (Wells & Olson, 2003). Their testimony is highly regarded as it allows for police, prosecutors, judges and juries to establi...
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.
For example, the old man that lived beneath the boy and his father testified that he heard a fight between the boy and the father and heard the boy yell, “I’m gonna kill you,” along with a body hitting the ground, and then claims that he saw the boy running down the stairs. With this information, along with other powerful eyewitness testimonies, all but one of the jury members believed this boy was guilty. The power of eyewitness testimony is also shown in Loftus’s (1974) study. In this study, Loftus (1974) found that those who claimed to “see” something were usually believed even when their testimony is pointless. She discovered in her study that only 18 percent of people convicted if there was no eyewitness testimony, 72 percent of people convicted when someone declared, “That’s the one!”, and even when the witness only had 20/400 vision and was not wearing glasses and claimed “That’s the one!”, 68 percent of people still convicted the person. This proves that in 12 Angry Men and Loftus (1974) study, eyewitness testimony is very powerful and influential in one’s decision to convict a
Minor consequences, might for instance, be confusing where one has placed something, like car keys. Such confusion can result in a simple inconvenience such as, the wasting of time. Although more serious consequence might for instance occur when one’s memory tricks the individual into giving false eyewitness accounts that might be costly to him, or other third parties. As such, it is important to critically analyze the dynamics of false memory formation and highlight methods that could be used to identi...
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.
Eyewitness testimony is defined as, “an area of research that investigates the accuracy of memory following an accident, crime, or other significant event, and the types of errors that are commonly made in such situations.” Much emphasis is placed on the accuracy of eyewitness testimony as often-inaccurate eyewitness testimony can have serious consequences leading to wrong convictions. Eyewitness testimony is a powerful tool within any field, particularly that of justice, as it is a readily accepted form of evidence that allows for convictions. However, Tests conducted by Loftus have shown an enormous swing from a non-guilty verdict, to guilty within the same case, simply through the introduction of an eyewitness. This alone displays the importance of eyewitness testimony, and accentuates the theory that jurors tend to over believe, or at least rely heavily on such accounts.
Memory is one of the most critical parts of cognition. It is important because it is involved in almost every aspect of cognition including problem solving, decision making, attention, and perception. Because of this importance, people rely on one’s memory to make important decisions. The value of one’s memory in this society is so high that it is used as evidence to either save one’s life or kill one’s life during murder trials. But as many of the cognitive psychologists know, human’s memory can cause many errors. One of these errors is false memory which is either remembering events that never happened or remembering events differently from the actual event. This finding of false memory raised big interests among psychologists and general public and many researches were done in order to find more about the false memory. The constructive approach to memory, which states that memory is constructed by person based on what really happened in addition to person’s other knowledge, experiences, and expectations, supports the idea of false memory. Just like what constructive approach to memory states, the false memory can be created by person’s knowledge, common biases, and suggestions. The present study was done in order to demonstrate one methodology that biases people to create and recall false memories. The present study is based on Deese’s experiment in 1959 and also on Roediger and McDermott’s experiment in 1995. The participants will be presented with sequence of words visually, and then they would have to classify a set of words as either in the sequence or not in the sequence. Our hypothesis is that people will create false memories and recall distractor words that are related to the sequence of words presented significantly m...
