The reliability of eyewitness testimony has become a popular research topic in applied and social psychology since Loftus and Palmer’s study in 1974 (see Steblay, 1997; Wright & Loftus, 1998; Deffenbacher, Bornstein, Penrod, & McGorty, for reviews). Participants viewed videos or slides of traffic accidents (Loftus & Palmer, 1974) or a criminal act (Roediger, Jacoby, McDermott, 1996; Cutler, Penrod, & Martens, 1987) and afterwards were asked several questions about what they had just seen. The manipulation in studies was that the researchers did not ask the same question to all participant, but instead changed the wording of one critical detail in the question. In Loftus and Palmer’s study, some of the subjects were asked “About how fast were the cars going when they hit each other?”, while other subjects were asked the same question with the verbs smashed, collided, bumped and contacted instead of the verb hit. Loftus and Palmer (1974) showed that changing a single verb induced the different participant groups to give different estimations of the car’s speed, and additionally to produce more false claims of having seen broken glass during later interrogation.
Loftus’s work and the studies that followed have demonstrated that an individual’s memory of an event can easily be distorted by post-event information, which is provided through questions that the researcher or police officer in case of a real life crime might ask the witness. But not only researchers’ questions have been found to distort memory. Several studies have indicated that when witnesses discuss an event together they can mistakenly incorporate elements of each other’s memories into their own memories (e.g., Gabbert, Memon, & Allan, 2003; Paterson & Kemp, 2006). ...

...g that people in everyday life tend to cue one another’s memory, and that this type of prompting is productive. The assumed benefit of collaborative remembering has also been referred to as cross-cueing (Wegner, 1985; Meudell et al., 1992, 1995). A benefit that, understandably, may be interesting for police investigations in cases for which multiple witnesses are heard.
However, although Meudell and colleagues (1992) demonstrated that two individuals always recalled more than one, they failed to demonstrate that social interaction facilitated performance and produced ‘emergent memories’, which are memories not available to either of the individual recalling on their own. In a second attempt to demonstrate cross-cueing, Meudell and colleagues (1995) manipulated the opportunity for cross-cuing by using a categorized list, but again failed to show emergent memories.
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 order to incriminate Danial Williams, Joseph Dick, Eric Wilson, and Derek Tice with the rape and murder of Michelle Moore-Bosko, Detectives Maureen Evans and Robert Ford conducted long, grueling interrogation sessions using many provocative and manipulative tactics. Throughout this process, Ford and Evans coerced the suspects into renegotiating their perception of the crime until an entirely new reality was created. This new reality evolved as the police elicited additional confessionary evidence to account for each new piece of physical evidence from the crime scene. Eventually, in an iterative process that had police editing their theories of the crime and then forcing the suspects to claim this new reality as their own, the reconciled reality of the crime became one that was consistent with both the criminal evidence and the suspects’ new perception. An analysis of empirical m...
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...
Humans have an incredible capability for thinking and memory. We can remember events from our past, for our future, and of things that have no relative meaning to ourselves. These memories can be traced back to different systems of our brains through a process of encoding, storage, and retrieval. As part of the retrieval process, memories can be remembered with or without their sources. As research has found, our memories are not labeled or tagged with their origin (Johnson, Hashtroudi, & Lindsay 1993). Because of this, our memory has developed a process called source monitoring. This is how we link our memories to the source that they developed from, usually using specific characteristics and general knowledge of the memory. For example, source monitoring includes identifying who told you something, whether or not you saw an event in real life, the time of the event and whether you told something to your friend or only thought about telling it. The source-monitoring framework for the process involved in pinpointing the origin of information by Johnson and colleagues, explains both vertical and distorted memory with a common set of principles. First, a specific memory consists of specific characteristics including spatial, temporal, and perceptual details. Secondly, the memories can differ in characteristics that can be used to find the origin. More extensive source monitoring can involve beliefs about memory and cognition as well as retrieving more information from memory and finding the source of the memory given these beliefs, other specific characteristics or general knowledge (Johnson et al. 1993). Sometimes these beliefs aren't always accurate. Because some people may be influenced by their personal ideologies during retriev...
The aim of the study is to examine own gender bias in eyewitness testimony by fully crossing gender of participant with gender of target in a simulated crime scene. The hypotheses that will be tested in this study include: a) female participants identify female target person more accurate, b) male participants identify male target person more accurate, and c) female and male participants identify male and female target equally
For this book report, I decided to read Hugo Münsterberg's On the Witness Stand. This book contains essays on psychology and crime and eyewitness testimony. Today this book is used as a reference for many issues in forensic psychology. For this report, I focused on two chapters of the book: Illusions and the Memory of the Witness. I am going to first summarize the two chapters I read then talk about what was going on at the time this book was written. I will then report some of the research in the book, and finish with my opinion on how this book has contributed to the literature and how it relates to the current knowledge of forensic psychology.
Human memory is flexible and prone to suggestion. “Human memory, while remarkable in many ways, does not operate like a video camera” (Walker, 2013). In fact, human memory is quite the opposite of a video camera; it can be greatly influenced and even often distorted by interactions with its surroundings (Walker, 2013). Memory is separated into three different phases. The first phase is acquisition, which is when information is first entered into memory or the perception of an event (Samaha, 2011). The next phase is retention. Retention is the process of storing information during the period of time between the event and the recollection of a piece of information from that event (Samaha, 2011). The last stage is retrieval. Retrieval is recalling stored information about an event with the purpose of making an identification of a person in that event (Samaha, 2011).

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.

Similar studies were done to a different set of college students and they tended to have the same results. After giving as much detail about each memory, the students were interviewed about what they may have written done about what they had remembered. During the last part of the experiment, each of the students were debriefed and asked to guess which memory they believed was false.
Eyewitness testimony is especially vulnerable to error when the question is misleading or when there’s a difference in ethnicity. 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. For instance, a group of students saw the face of a young man with straight hair, then heard a description of the face supposedly written by another witness, one that wrongly mentioned light, curly hair. When they reconstructed the face using a kit of facial features, a third of their reconstructions contained the misleading detail, whereas only 5 percent contained it when curly hair was not mentioned (Page 359). This situation shows how misleading information from other sources can be profoundly altered.
According to Sternberg (1999), memory is the extraction of past experiences for information to be used in the present. The retrieval of memory is essential in every aspect of daily life, whether it is for academics, work or social purposes. However, many often take memory for granted and assume that it can be relied on because of how realistic it appears in the mind. This form of memory is also known as flashbulb memory. (Brown and Kulik, 1977). The question of whether our memory is reliably accurate has been shown to have implications in providing precise details of past events. (The British Psychological Association, 2011). In this essay, I would put forth arguments that human memory, in fact, is not completely reliable in providing accurate depictions of our past experiences. Evidence can be seen in the following two studies that support these arguments by examining episodic memory in humans. The first study is by Loftus and Pickrell (1995) who found that memory can be modified by suggestions. The second study is by Naveh-Benjamin and Craik (1995) who found that there is a predisposition for memory to decline with increasing age.
