Suggestibility and Human Memory

632 Words2 Pages

Suggestibility in human memory is considered as the phenomenon called the misinformation effect. The misinformation effect occurs when the misleading information influence a person’s memory of the witnessed event and change how that person describes that event later. Moreover, the misleading information in this effect is referred to as misleading postevent information (MPI) (Goldstein, 2008).

Loftus and her colleagues contribute a lot to the early studies of misinformation effect. In one of the classical misinformation experiments (Loftus, Miller, & Burns, 1978), participants first saw a slide show of a car accident and one of the sildes depicted a car at a stop sign. Participants in the experimental group got the misleading information that the actually there was a yield sign in the silde inseated of a stop sign. The misleading information was given by asking questions about the event in the sildes, such as “Did another car pass the red Datsun when it was stopped at the yiled sign?”. Later, a memory test about the information shown in the sildes was given to the participants. ...

  • Source Monitoring: A look at Errors

    1604 Words  | 4 Pages

    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...

  • Repressed Memory: The Missinginformation Effect

    1726 Words  | 4 Pages

    Imagine having a memory of a very traumatic event resurface in your mind after forgetting about it for twenty years. That is what happened to Eileen Franklin in 1989 when she had recovered what is called a repressed memory of her father, George Franklin, killing her friend in 1969, which eventually lead to her father getting a sentence of life in prison (Beaver, 1996). A repressed memory is a memory that is not forgotten, but is a memory of something traumatic that is blocked and not recovered unless triggered by something. Although her descriptions of the event were very vivid, describing colors and sounds, most of what she described could be proven inaccurate. Some of what she described was information that was misreported in newspapers that she had probably read or been told about in the past. This is an example of the misinformation effect. Misinformation effect is when someone is misled by information about an event that they witnessed and has an effect on how they remember that event later. This is just one example of how the misinformation effect can change how an event is described.

  • The Negative Effects Of False Memory

    964 Words  | 2 Pages

    Research has shown that even though information may be committed to memory, what is retrieved can be altered during the encoding process. It has been said that, “the recollection of memory can be manipulated and or large aspects of the event can be confabulated.” (Cain,1997). Moreover, the recollection of past experiences can negatively affect future decisions, opinions, and more significant outcomes such as an eyewitness. This type of impact is due to something called, “false memories.” False memories can be defined as “an recollection of an event that never actually occurred.” False memories are said to be normal occurrences and have little impact on lives. However, Loftus and Palmer argue something different. In 1974, Loftus and Palmer conducted an experiment to test out the theory behind “false memories.” Their aim was to show that language used in eyewitness testimony can alter memory. People in this experiment were asked to estimate the speed of motor vehicles using different ways of questioning. Loftus and Palmer asked questions in regards to vehicle speed because typically that is something that most people are bad at estimating. Therefore these people would be more vulnerable and open to suggestions. The procedure of this experiment involved participants watching a video of cars. Participants were asked what they had seen in regards to how that car came in contact with the other car. Loftus and Palmer used words like “crashed, collided, hit, and smashed.” Their findings concluded that the estimated speed was affected by the verb used to describe the cars’ contact with one another. It seem as if participants saw that the verbs as clues of the speed the cars were going. Loftus and Palmer also came to the conclusion that there could only be two reasons for their findings. Those reasons were Response- bias factors or the fact that the memory representation is alter.

  • Eyewitness Identification and Reliable Testimony

    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).

    The misinformation effect occurs when people’s recollection of events is distorted by the information given to them after the event happened. This means it is false but possible that can confuse our memory. It is referring to the impairment of memory for the past that arises after exposure to the misleading information. The misinformation effect is in the eyewitness testimony. Eyewitness testimony means an information or evidence that provided by people who witness an event such as a crime, reporting from our memory. Researcher has proves their research that the information or evidence given by the eyewitnesses may not accurate.

    Human memory is highly susceptible to modifications due to the compelling nature of false memories. This causes the recollection of events to be different from the way they happened or to be non-existent. (Roediger, Jacoby and McDermott, 1996). The first study by Loftus and Pickrell (1995) was to understand and determine if human’s episodic memory, which is the recollection of past events in their thoughts and feelings at that point of time, could be modified by suggestive information. (Wheeler, Stuss and Tulving, 1997). The independent variables were the types of information (3 true and 1 false) given...

  • A Distortion of Reality

    People fail to notice when they are presented with something different from what they originally chose and tend to come up with explanations as to why they picked that specific choice. In this research paper, Cochran, Greenspan, Bogart, and Loftus discuss how choice blindness can lead to distorted eyewitness memories. In their experiment, the studied if the participants in their research realized modifications to their memory reports and if these changes could possibly effect the participants’ memory. Cochran, Greenspan, Bogart, and Loftus conducted two different experiments. Experiment 1 was constructed on two self-sourced vs. other-sourced between participants and two misinformation vs. control within participants. They had participants watch a slideshow that showed a woman intermingling with three other characters and one of them steals her wallet. Then they completed a personality measure in 15 minute retention interval which was followed by questions about their memories from the slideshow. After, they were given another 15 minute retention interval and then shown their responses to the memory question, but three of their responses were revised. According to Cochran, Greenspan, Bogart, and Loftus (2016), “experiment 1 demonstrated that when witnesses were exposed to altered versions of their own memory reports for episodic details of an event, their memories changed to be consistent with
