Discuss the Reliability of One Cognitive Process

The aim of Loftus and Palmer’s study was to investigate how language can be used to manipulate or distort one’s memory in an eyewitness testimony.

Memory is divided into three categories. These categories consist of: sensory memory, short term memory and long term memory, out of these short term memory is the main focus in this essay. It has been widely researched due to interest of how much memory can be stored, how long this memory can be stored for and what information is memorised.

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.

Memory is the process of encoding, storing and retrieving information in the brain. It plays an import role in our daily life. Without memory, we cannot reserve past experience, learn new things and plan for the future. Human memory is usually analogous to computer memory. While unlike computer memory, human memory is a cognitive system. It does not encode and store everything correctly as we want. As suggested by Zimbardo, Johnson and Weber (2006), human memory takes information and selectively converts it into meaningful patterns. When remembering, we reconstruct the incident as we think it was (p. 263). Sometimes our memory performance is incredibly accurate and reliable. But errors and mistakes are more commonly happen, because we do

Memory is a set of cognitive processes that allow us to remember past information (retrospective memory) and future obligations (prospective memory) so we can navigate our lives. The strength of our memory can be influenced by the connections we make through different cognitive faculties as well as by the amount of time we spend devoting to learning specific material across different points in time. New memories are created every time we remember specific event, which results in retrospective memories changing over time. Memory recall can be affected retrospectively such as seeing increased recall in the presence of contextual cues or false recall of information following leading questions. Memory also includes the process

The Car Crash Study was done in 1974 by Loftus and Palmer that was aimed to test their theory that the language used in an eyewitness testimonies can alter the eyewitness’s memory of the event. They got 45 American students and showed them 7 films of traffic accidents, ranging from 5 to 30 seconds, in a random order. Afterwards the subjects were asked to describe what happened as if they were at the accident. They were then asked more specific questions such as, “About how fast were the cars going when they (smashed/ collided/ bumped/ hit/ contacted) each other?’. This was to see if the if the verb used in the question would affect the answers given by the subjects which it did. In the next part of the experiment they showed 150 students a one-minute film that showed a car driving through the country side followed by four seconds of a multiple traffic accident. Afterwards they split the students into three groups and asked them different questions. The first group was asked “How fast were the cars going when they hit each other?”, the second group was asked “How fast were the cars going when they smashed into each other?”, and the third group was kept as a control group and wasn’t asked anything. One week later they were asked, without seeing the film, ten questions about the film. One question asked “Did you see any broken glass? Yes or No?” which there was none. The results showed that more participants who were asked “How fast were the cars going when they smashed?” said

Memory is defined as “the mental capacity to encode, store, and retrieve information” (American Psychological Association, 2002). It is a part of the means by which humans function. The process of forming and recalling memories involves various complex neurological processes and disruptions to these processes can result in loss of memory or the inability to form new memories. Amnesia is a memory disorder, in which, due to trauma or a head injury, certain parts of the memory is inaccessible. The two main types of amnesia are anterograde amnesia and retrograde amnesia. Anterograde amnesia refers to the inability to create new memories (Mastin, 2010). “Retrograde

In this paper I will revisit Russon’s definition of memory, and three of the aspects that he presents as important in the memory process. I will also argue that our body play an important role for our remembering, as does the objects we interact with. As well as present my position on Russon description of memory demonstrating that Russon’s description is indeed relatable to the actual human experience.

Memory – what it is, how it works, and how it might be manipulated – has long been a subject of curious fascination. Remembering, the mind-boggling ability in which the human brain can conjure up very specific, very lucid, long-gone episodes from any given point on the timeline of our lives, is an astounding feat. Yet, along with our brain’s ability of remembrance comes also the concept of forgetting: interruptions of memory or “an inability of consciousness to make present to itself what it wants” (Honold, 1994, p. 2). There is a very close relationship between remembering and forgetting; in fact, the two come hand-in-hand. A close reading of Joshua Foer’s essay, “The End of Remembering”, and Susan Griffin’s piece, “Our Secret”, directs us

‘The language used in eyewitness testimony can alter an individual’s memory’, the Loftus and Palmer study was carried out to test that hypothesis. Two experiments were carried out within the study. The study had a quasi-experimental design. Experiment one involved forty-five students participates, the participants were shown various films of automobile accidents, after the participants viewed the films they were questioned about what they have just seen. A number of questions specific to the automobile accident were presented in a questionnaire to the participants, however the question contained a paramount question of interest, this being

Memory is used as a tool to preserve past realities, but memory is never an absolute preservation.

Memory does not work like a video camera, smoothly recording every detail. Instead, memory is more of a constructive process. We remember the details that we find most important and relevant. Due to the reconstructive nature of memory, the assimilation of old and new information has the ability to cause vulnerable memories to become distorted. This is also known as the misinformation effect (Loftus, 1997). It is not uncommon for individuals to fill in memory gaps with what they assume they must have experienced. We not only distort memories for events that we have observed, but, we may also have false memories for events that never occurred at all. False memories are “often created by combing actual memories with suggestions received from

Questionnaires were then completed regarding the details of the clip. The independent variable again was the question around the speed the vehicles were travelling at when the collision occurred. The results showed that subjects interrogated with Smashed give a mean speed of 10.46mph and those with hit a mean of 8.00 mph which evidenced a significantly different result. One week later the participants were invited back and interrogated as to whether they saw glass in the accident to which there was none. The expectation was that the participants who had initially been questioned with the Verb Smashed would be more likely to give a Yes result. Furthermore, when participants where asked whether there was glass in the accident the results supported the expectation. With over double the participants who received the verb smashed responding yes in comparison to the participants questioned with hit. The results supported the Hypotheses, and the idea that we as humans have one memory however, it is made up of two types of information the one we first gain from the event its self and secondly information gained about the event that we gain afterwards.

Memory makes us. It is, to an extent, a collection of unique and personal experiences that we, as individuals, have amassed over our lifetime. It is what connects us to our past and what shapes our present and the future. If we are unable remember the what, when, where, and who of our everyday lives, our level of functioning would be greatly impacted. Memory is defined as or recognized as the “sum or total of what we remember.” Memory provides us the ability to learn and adjust to or from prior experiences. In addition, memory or our ability to remember plays an integral role in the building and sustaining of relationships. Additionally, memory is also a process; it is how we internalize and store our external environment and experiences. It entails the capacity to remember past experiences, and the process of recalling previous experiences, information, impressions, habits and skills to awareness. It is the storage of materials learned and/or retained from our experiences. This fact is demonstrated by the modification, adjustment and/or adaptation of structure or behavior. Furthermore, we as individuals, envision thoughts and ideas of the present through short-term memory, or in our working memory, we warehouse past experiences and learned values in long-term memory, also referred to as episodic or semantic memory. Most importantly, memory is malleable and it is intimately linked to our sense of identity and where we believe we belong in the world.

Memory facilitates necessary functions in daily life activities, but it is not a perfect mechanism in operation. Goldstein (2011) states that memory is, “…the process involved in retaining, retrieving, and using information about stimuli, images, events, ideas, and skills after the original information is no longer present” (p.116). There are many adaptive functions within the complexities of the human memory system and the interlinked constructs between each function leave room for doubt in the accuracy of recollection. Study of the human mind has opened avenues of discovery on the inner workings of our brains and the resulting knowledge suggests that humans are prone to creating false memories and even remembering things that never actually happened. A great deal of information has been written explaining the nature of memory errors and within the following pages a real-life case offers a glimpse into how recall distortions and memory errors can wield unpleasant consequences. Memory errors can be avoided with a significant effort, but the truth remains that no one is perfect and memories are subject to individual bias.
