The Reliability of Eyewitness Testimony
Part 1 - How reliable is Eyewitness testimony?
The Reconstructive nature of memory - Schemas and Stereotypes
The reconstructive nature of memory is related to the schema theory. A schema is a package of memory that is organized and developed throughout our lives. Schemas are stored in long term memory. Most people have similar schemas and this was recognized by Bower, Black and Turner (1979) when they asked several people to recall the schema for the most important things they do when they go out to a restaurant for a meal. They found out that most people put the same main aspects in their schemas.
Bartlett's theory of Reconstructive Memory is

Some parts of information were forgotten and others were exaggerated.
Bartlett's study showed how our cultural expectations or stereotypes lead to predictable changes in memory. Stereotypes are schemas that summarize large amounts of information. Like schemas, stereotypes influence memory. He argued that schemas affect the retrieval process rather than the initial storage, but a study by Cohen (1981) suggested that schemas and stereotypes are important at both stages of memory: initial storage and retrieval.
The effects of leading questions
An eyewitness's testimony about an event can be affected by the questions that are asked. For example, if the experimenter asks, "did you see the broken headlight?" rather than "did you see a broken headlight?" the use of the word "the" suggests there was a broken headlight and therefore the participant goes on to build up a memory for that headlight (Loftus and Zanni 1975). The language used in questioning eyewitnesses may alter what they remember.
Loftus and Palmer (1975) showed their participants a series of projector slides of a multiple car accident. The participants then answered specific questions. It was found out that the information implicit in the question affected memory, even though the questions apparently only differed
Loftus and Palmer support the reconstructive memory hypothesis. They believe that information gathered at the time of an icident is
Credability of Eyewitness Testimony Is Eyewitness testimony reliable and accurate? Include case studies to back this up. EWT refers to evidence supplied by people who witness a specific event or crime, relying on their own memory. Statements often include descriptions given in a criminal trial and subsequent identification by individuals who were present at the crime scene. EWT is likely to dependent on reconstructive memory(Bartlett,1932) which describes how memory is more than a passive recall.
A schema according to Henry Gleitman (2007) is a mental representation that summarises what we know about a certain event or situation. Schemas reflect the fact that many aspects of our experience are redundant and schemas seek to provide a summary of this redundancy.
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.
To see how much an individual’s schemas affect their memory of a story and whether or not memory is reconstructive.
Evaluation of Research Into Eyewitness Testimony Eyewitness testimony investigates the accuracy of memory following a crime or an incident worth interrogating and the types of errors made in such situations. Sometimes eyewitness testimony can be unreliable, which can lead to horrific consequences in a court of law for example, hence many Psychologists have studied and theorized why this happens. One leading researcher on Eyewitness testimony is Elizabeth Loftus and her colleagues, in 1975, participants were shown an event by film of a car crash, the participants were split into 2 groups and ask questions on what they had just seen, Group 1 were asked questions that were consistent with the
Research into false memory has been carried out to determine how reliable the memory can be. Loftus (2003) looked at eyewitness memory and how accurate it can be. In one study Loftus showed films of traffic
"A Room with an Overview: the Effects of Schematic Processing, Mood and Exposure Duration on Memory Accuracy," written by Andrea Vranić and Mirjana Tonković, talks about how memories are never exactly how people remember them and they are indeed, rehabilitated and distorted. The article explains the different aspects that improve the accuracy of a person's memory. The Schema Theory is explained in the article and states "Constructivism, as opposed to associationism, argues that people build new knowledge and understanding of reality from an interaction of their experiences and the knowledge and ideas they already have" (Vranić and Tonković 358-9). This theory expresses that when a schema, a representation of a plan, is experienced, then the
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

There has been substantial research done on areas of false memory and child suggestibility in eyewitness testimony. One relevant research is the study of “The origin of children’s implanted false memory” by Henry Otgaar, Bruno Verschuere, Ewout H. Meijer, and Kim van Oorsouw. In this article, Otgaar et al. (2012) conducted a study to determine whether implanted false memories in children represent actual memory traces or are they merely a result of compliance. Participants consisted of forty-five children, both males and females between the ages eight and ten, from elementary schools in the Netherlands. At the start of the experiment, the researchers interviewed each child individually about their memories from past events. During the interview, the children were presented with a true narrative about an experienced event (first day at school) first then followed by a false narrative about a fictitious event (hot air balloon
I will be discussing is eyewitness testimony. Eyewitness testimony refers to an account given by people of an event they have witnessed. Eyewitness testimony has been researched by many people, but Elizabeth Loftus was a major part in showing people that memory can be changed by suggestion. Remembering what happened in an accident or crime can be a major factor in an investigation. Loftus’s study showed that when people are being questioned about an event just the vocabulary used can affect their answers to a question. This shows not all information is accurate. It can limit an investigation and the outcome of a case. This has positively impacted my life because if I ever ask someone about what happened my words could affect their answers and
Eyewitness is the most important aspect for a criminal event that has occurred. Through eyewitness police or relevant forces might be able to get one step closer to catching the criminals. There is no age limit to provide testimony but in recent years, children’s testimonies are also acceptable in courtroom. This will be typically involving rape incident, abuse incident, and robbery incident and so on. There are more procedures involved in extracting information from affected children compared to an adult as children are more sensitive, also their mental state is still fragile. Studies have talked about the accuracy of statement given by children who witnesses the crime. In a nut shell researchers theorize that the pattern of questions asked to the eyewitness may affect the performance throughout the age group. A study done by Lipton, 1977 said that the type of
I personally believe that eyewitnesses are not reliable since there are a lot of things to take into consideration: bias, memory, character, etc. There is no formula to know whether someone is telling the truth with accuracy about the story that they are telling. For me is all how believable or if they believe the story that they are telling. The bigger and elaborate the story is, the more proof and evidence I require from the person that is telling the story. The more simplistic the story is, more than likely I will believe their story and accepted as the truth; now, if for some reason, I find something off-putting or do not believe their source, then I will not believe or trust his story or give them any type of credit. I truly think that we are fortunate and bless to have multiple gospels’ accounts available to us, and not including the ones that are from the Bible. This is good news for us because this way we compare and contrast with peoples’ testimony that took place at the same place and time. That being said, there are discrepancies between gospels when it comes to their religion’s opinions and the accuracy of the events that took place in history. Now, we must take into consideration of whether the authors knew about one another or if they did not hear about Jesus into later in their lives; however, if both authors are followers of Jesus’s word and they are real disciples, then one should be skeptical about what they say about the gospel.
False Memories and Eyewitness Testimony Once in a while we all like to reminisce and think of the past at some point. We remember our favorite toy, our best friends, favorite movie, and past memories, but what if what we think we know is just something that our mind has created for us. That specific event that we were so certain happened never actually did. We remember the colors the smells the people that were there, but it never really happened.
