Brain Games- False Memory and Misinformation Effect

A week later, the participants were once again asked a series of questions, including " Did you see broken glass? Most of the participants correctly answered no, but those who had been asked the " smashed into " version of the question in the initial interview were more likely to incorrectly believe that they had indeed seen broken glass. How can such a minor change lead to such differing memories of the same video clip? Experts suggest that this is an example of the misinformation effect at work. This memory phenomenon takes place when introducing misleading or incorrect information into memory and even contribute to the formation of false memories.

Why does the misinformation effect happen? There are a few different theories. Research has shown that there are several factors that can contribute to the misinformation effect and make it more likely that false or misleading information distorts memories of events. The misinformation effect can have a profound impact on our memories. What can prevent intervening information and events from altering memories or even creating false memories?

Writing down your memory of an important event immediately after it happens is one strategy that might help minimize the effects. That said, even this strategy can introduce subtle errors and writing these mistakes will further cement them in your memory. Being aware that you are susceptible to influence on your memory is a helpful and important strategy. While you might have good memory, understand that anyone can be affected by the misinformation effect. Ever wonder what your personality type means?

Source amnesia is the inability to remember where, when, or how previously learned information was acquired, while retaining the factual knowledge.

Source amnesia is part of ordinary forgetting, but can also be a memory disorder. People suffering from source amnesia can also get confused about the exact content of what is remembered. Source confusion, in contrast, is not remembering the source of a memory correctly, such as personally witnessing an event versus actually only having been told about it. An example of this would be remembering the details of having been through an event, while in reality, you had seen the event depicted on television. Increasing evidence shows that memories and individual perceptions are unreliable, biased, and manipulable. Eyewitness testimony has been considered a credible source in the past, but its reliability has recently come into question.

Research and evidence have shown that memories and individual perceptions are unreliable, often biased, and can be manipulated. Nobody plans to witness a crime; it is not a controlled situation. There are many types of biases and attentional limitations that make it difficult to encode memories during a stressful event. When witnessing an incident, information about the event is entered into memory. However, the accuracy of this initial information acquisition can be influenced by a number of factors. One factor is the duration of the event being witnessed. In an experiment conducted by Clifford and Richards , participants were instructed to approach police officers and engage in conversation for either 15 or 30 seconds.

The experimenter then asked the police officer to recall details of the person to whom they had been speaking e. The results of the study showed that police had significantly more accurate recall of the second conversation group than they did of the second group. This suggests that recall is better for longer events. The other-race effect a. Studies investigating this effect have shown that a person is better able to recognize faces that match their own race but are less reliable at identifying other races, thus inhibiting encoding. Perception may affect the immediate encoding of these unreliable notions due to prejudices, which can influence the speed of processing and classification of racially ambiguous targets.

The ambiguity in eyewitness memory of facial recognition can be attributed to the divergent strategies that are used when under the influence of racial bias. A person focuses on a central detail e. While the weapon is remembered clearly, the memories of the other details of the scene suffer. This effect occurs because remembering additional items would require visual attention, which is occupied by the weapon. Therefore, these additional stimuli are frequently not processed. Trials may take many weeks and require an eyewitness to recall and describe an event many times. These conditions are not ideal for perfect recall; memories can be affected by a number of variables. The accuracy of eyewitness memory degrades swiftly after initial encoding.

Unsurprisingly, research has consistently found that the longer the gap between witnessing and recalling the incident, the less accurately that memory will be recalled. There have been numerous experiments that support this claim. Malpass and Devine compared the accuracy of witness identifications after 3 days short retention period and 5 months long retention period. The forgetting curve of memory : The red line shows that eyewitness memory declines rapidly following initial encoding and flattens out after around 2 days at a dramatically reduced level of accuracy.

In a legal context, the retrieval of information is usually elicited through different types of questioning. A great deal of research has investigated the impact of types of questioning on eyewitness memory, and studies have consistently shown that even very subtle changes in the wording of a question can have an influence. One classic study was conducted in by Elizabeth Loftus, a notable researcher on the accuracy of memory. Age has been shown to impact the accuracy of memory as well. Younger witnesses, especially children, are more susceptible to leading questions and misinformation. There are also a number of biases that can alter the accuracy of memory. For instance, racial and gender biases may play into what and how people remember.

Finally, the emotional tone of the event can have an impact: for instance, if the event was traumatic, exciting, or just physiologically activating, it will increase adrenaline and other neurochemicals that can damage the accuracy of memory recall. This interference often occurs when individuals discuss what they saw or experienced, and can result in the memories of those involved being influenced by the report of another person. Some factors that contribute to memory conformity are age the elderly and children are more likely to have memory distortions due to memory conformity and confidence individuals are more likely to conform their memories to others if they are not certain about what they remember. Some research indicates that traumatic memories can be forgotten and later spontaneously recovered.

The issue of whether memories can be repressed is controversial, to say the least. Some research indicates that memories of traumatic events, most commonly childhood sexual abuse, may be forgotten and later spontaneously recovered. However, whether these memories are actively repressed or forgotten due to natural processes is unclear. In one study where victims of documented child abuse were re-interviewed many years later as adults, a high proportion of the women denied any memory of the abuse.

Some speculate that survivors of childhood sexual abuse may repress the memories to cope with the traumatic experience. Traumatic memories are encoded differently than memories of ordinary experiences. In traumatic memories, there is a narrowed attentional focus on certain aspects of the memory, usually those that involved the most heightened emotional arousal. For instance, when remembering a traumatic event, individuals are most likely to remember how scared they felt, the image of having a gun held to their head, or other details that are highly emotionally charged.

The limbic system is the part of the brain that is in charge of giving emotional significance to sensory inputs; however, the limbic system particularly one of its components, the hippocampus is also important to the storage and retrieval of long-term memories. Supporters of the existence of repressed memories hypothesize that because the hippocampus is sensitive to stress hormones and because the limbic system is heavily occupied with the emotions of the event, the memory-encoding functionality may be limited during traumatic events. The end result is that the memory is encoded as an affective i. In this way, traumatic experiences appear to be qualitatively different from those of non-traumatic events, and, as a result, they are more difficult to remember accurately.

Psychological disorders exist that could cause the repression of memories. Psychogenic amnesia, or dissociative amnesia, is a memory disorder characterized by sudden autobiographical memory loss, said to occur for a period of time ranging from hours to years. More recently, dissociative amnesia has been defined as a dissociative disorder characterized by gaps in memory of personal information, especially of traumatic events.

These gaps involve an inability to recall personal information, usually of a traumatic or stressful nature. Psychogenic amnesia is distinguished from organic amnesia in that it is supposed to result from a nonorganic cause; no structural brain damage or brain lesion should be evident, but some form of psychological stress should precipitate the amnesia. However, psychogenic amnesia as a memory disorder is controversial. Memories of events are always a mix of factual traces of sensory information overlaid with emotions, mingled with interpretation and filled in with imaginings.

Thus, there is always skepticism about the factual validity of memories. There is considerable evidence that, rather than being pushed out of consciousness, traumatic memories are, for many people, intrusive and unforgettable. In this study, subjects were given a booklet containing three accounts of real childhood events written by family members and a fourth account of a fictitious event of being lost in a shopping mall. A quarter of the subjects reported remembering the fictitious event, and elaborated on it with extensive circumstantial details. While this experiment does show that false memories can be implanted in some subjects, it cannot be generalized to say that all recovered memories are false memories.

Nevertheless, these studies prompted public and professional concern about recovered-memory therapy for sexual abuse. However, these leaders also agree that it is possible to construct convincing pseudomemories for events that never occurred. The mechanism s by which both of these phenomena happen are not well understood and, at this point it is impossible, without other corroborative evidence, to distinguish a true memory from a false one.
