False memories are memories of something that did not happen (Radvansky, 2010). Steven J.Frendal and colleagues researched the effect of sleep deprivation on false memories. In this study researchers examined the relationship between self-reported sleep and false memories. Researchers suggest that under certain conditions, sleep deprivation can increase the risk of developing false memories (Frendal et al., 2014). To test this hypothesis, researchers provided participants with a misinformation task when participants were sleep deprived during event encoding. Frendal and

Participants reported an average of 6.8 hr of sleep (SD = 2.0). 28 participants (15%) reported 5 or fewer hours of sleep. Researchers coded the participants as having restricted sleep. The remaining 165 participants (85%) were used as a reference group (Frendal et al., 2014). The news event was rated first , participants in the restricted-sleep group were significantly more likely than participants in the reference group to report that they had seen the video (54% vs. 33%), χ2(1, N = 193) = 4.2, p = .04, ϕc = .15. However, the results indicated that the groups did not differ when questioned in the follow-up interview. 21% of the restricted sleep group and 20% of the reference group claimed that they had seen the video, χ2(1, N = 193) = 0.03, p = .86. Therefore, restricted sleep was associated with initial false reports on the questionnaire, but not with false reports in the follow-up interview. Researchers compared the two group’s correct answers in the surveys as well as the amount of misinformation. There were no significant findings. Between the two groups there was only a 10% difference in incorporating the misinforming narratives as something they saw, making it an insignificant finding (Frendal et al.,
Repressed vs. false memories has been a critical debate in criminal cases and daily life problems. Throughout the years many people has claimed to recover repressed memories with the simplest triggers varying from a gaze to hypnosis. However, a large number of repressed memories claimed are considered as false memories because the images were induced through hypnosis and recalled during a therapy sesion. In the film “divided memories” the main intention was to inform the audience the importance of repressed memories and how those memories can change the lives of the people involved, whether the memory was considered repressed or false. It shows different cases of women being victims of sexual abuse in childhood and how they had those memories repressed. Additionally, the film

Can memories be biased? Researchers Postarino and Doyle-Portillio (2013); Bernstein and Loftus (2009); and Bartholomew (2009) found increasing evidence to suggest that the answer to this question is yes. Explicit and implicit memories are encoded differently, but it appears both can be fallible. Also worth noting, is that this can happen without a person conscious awareness. Kolb and Whishaw (2014) examined studies that gave participants a list of words, then gave them a second list. The second list contained some, but not all items from the first list, but many participants thought the word sugar was on both, when in fact it was only on the second. Similar words like cake, sweet, and candy were on the first so this seemed to confuse participants. This phenomena researchers refer to as false memory. False memory is different from a lie; unlike a lie, the individual in this case may give false account of the past truly believing that he or she is telling the truth. In other words, false memory can simply be defined as mental experience that is wrongfully considered as the truthful representation of the past. False memories can result in both minor and serious consequences Bernstein & Loftus, 2009; Bartholomew, 2009).
Repressed memory is the involuntary block on a memory considered to be extremely stressful and appalling in nature. It is theorized that repressed memory is a form of amnesia that is not associated with typical forgetfulness in a person. When a person experiences something extremely severe in nature, such as childhood sexual abuse for example, their mind sometimes refuses to remember that event because it is so painful to recall. In some cases events of extreme trauma, often during adulthood such as post-traumatic stress, can actually cause a reverse effect and an increase in memorability. Some even believe that it is possible to repress memories voluntarily. It has been a topic that has eluded many psychologists today and has been thoroughly researched for the past century. This paper will explore different theories and ideas on whether or not repression is true or just another pseudo-science.
Remembrance is an integral part of our everyday lives. Both pleasant and unpleasant memories shape who we are as human beings. The definition of memory is two fold 1. “the faculty by which the mind stores and remembers information” and 2. “Something remembered from the past; a recollection” (Google Definition). The life of memory has three stages in which it is created. An event occurs in ones life it becomes encoded and stored in the brain. Following the encoding, the brain then has full access to retrieve the memory in a response to any current activity or thought. Memories are unique to each person. There are three main types of memories that are studied. An individual memory is one that is formed by his or her personal experiences. An institutional
Have you ever wondered why you find yourself recalling memories that, later you realized, they never actually occurred? If your answer is yes, then you’ve probably personally experienced this. If your answer is no, maybe you have indeed experienced this but, you just didnt realize it or didn’t understand it. Well, in order to understand the whole idea behind “false memories”, one must first understand “memory” in general. When asked about “memory” many will often describe it as “the mental capacity of receiving and recalling facts, events, impressions, or of recalling past experiences.” (Squire, 2009) Some of the common examples that are often described includes the process of studying for an exam or the process of trying to recall where
Recovered memories of childhood trauma and abuse has become one of the most controversial issues within the field of psychology. Controversy surrounding repressed memory - sometimes referred to as the memory wars – reached its’ peak in the early 1990s, where there was a rise in the number of people reporting memories of childhood trauma and abuse that had allegedly been repressed for many years (Lindsay & Read, 2001). There are a number of different factors that have contributed to the dispute surrounding recovered memories. Firstly, there is an ongoing debate about whether these types of memories actually exist or whether these accusations arose as a result of suggestive therapeutic procedures. In particular, this debate focuses on two main
False memory syndrome (FMS), also known as pseudomemories or illusionary memories, is defined as memories of traumatic experiences which are false, but the person determinedly believes to be true. These memories of traumatic experiences usually are associated with childhood sexual abuse (CSA) and even in rare cases satanic ritual abuse (SRA). False memory syndrome cases involving childhood sexual abuse are most commonly related to women and children. Also related with false memory syndrome is recovered memories, which is defined as the remembrance of childhood sexual abuse of which a person had no previous awareness of before. These recovered memories often take control over a person’s personality and change their behaviors and lifestyle. It is often difficult for people with false memory syndrome to see the possibility that their recovered memories may be incorrect. False memory
Have you ever been an eyewitness at the scene of a crime? If you were, do you think that you would be able to accurately describe, in precise detail, everything that happened and remember distinct features of the suspect? Many people believe that yes they would be able to remember anything from the events that would happen and the different features of the suspect. Some people, in fact, are so sure of themselves after witnessing an event such as this that they are able to testify that what they think they saw was indeed what they saw. 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.

Memory is one of the most critical parts of cognition. It is important because it is involved in almost every aspect of cognition including problem solving, decision making, attention, and perception. Because of this importance, people rely on one’s memory to make important decisions. The value of one’s memory in this society is so high that it is used as evidence to either save one’s life or kill one’s life during murder trials. But as many of the cognitive psychologists know, human’s memory can cause many errors. One of these errors is false memory which is either remembering events that never happened or remembering events differently from the actual event. This finding of false memory raised big interests among psychologists and general public and many researches were done in order to find more about the false memory. The constructive approach to memory, which states that memory is constructed by person based on what really happened in addition to person’s other knowledge, experiences, and expectations, supports the idea of false memory. Just like what constructive approach to memory states, the false memory can be created by person’s knowledge, common biases, and suggestions. The present study was done in order to demonstrate one methodology that biases people to create and recall false memories. The present study is based on Deese’s experiment in 1959 and also on Roediger and McDermott’s experiment in 1995. The participants will be presented with sequence of words visually, and then they would have to classify a set of words as either in the sequence or not in the sequence. Our hypothesis is that people will create false memories and recall distractor words that are related to the sequence of words presented significantly m...
The mistaken recollection of information or the recollection of an event that never happened is known as a false memory (Rajagopal & Montgomery, 2011). The study of false memories has been of interest to cognitive psychologists (Otagaar, Smeets & Scoboria, 2013) for many years as it implies that human memory is vulnerable to the influence of external information, it also implies that our ability to recall events may not always be accurate. One major issue that has arisen with the research on false memories is the argued validity of eyewitness testimony (Wade, Green & Nash, 2011). Eyewitness testimony is the verified report made by someone who witnessed a crime (Wade et.al., 2011). False memories can interfere with the correct recollection of criminal offences which can potentially result in inaccurate accusations of a crime (Wade et.al., 2011). Researchers have been interested in studying false memories to develop a better understanding of how false memories work, and to what extent our memories can be assumed accurate (Jou & Flores, 2013).
