Memory is an important skill used in every day life, from identifying suspects of a crime to remembering if you turned the oven off before leaving the house. However, the accuracy of human memory is a topic of great debate and some even question whether or not we should trust our memories at all. This essay will argue that flashbulb memory is not reliably accurate when it comes to recalling details of past events because many details have the potential to be forgotten. After discussing an experiment conducted by Schmolck, Buffalo, and Squire that tested the accuracy of flashbulb memories over a period of 32 months, and a study by Talarico and Rubin that compared the accuracy of flashbulb memories to everyday memories, it will become clear that flashbulb memories are certainly not reliably accurate in terms of recalling details of past events.
Paper 1:
In 1995, Schmolck, Buffalo, and Squire (2000) began a study that would test the accuracy of recollections of the O.J. Simpson murder trial and they discovered that flashbulb memories were vulnerable to distortion and inaccuracies over time. 222 undergraduate psychology students at the University of California participated in this study that initially involved recalling how they had first heard the results of the trial on October 6, 1995 (three days after the verdict was released) (Schmolck et al., 2000). The independent variable in this study was the time after the initial event that the follow-up questionnaires were given which was either 15 or 32 months after the event. The dependent variable is the accuracy of the flashbulb memories at the follow-up tests. The second questionnaire, sent out after 15 months, was delivered to half the students, of these only 28 were returned (14 mal...

...re studies. Compare younger participants to older.
- Questionnaires should be sent out to all participants at each interval rather than splitting them into groups.
- Use equal number of males and females.
Finally, after analysing a study by Schmolck, Buffalo, and Squire (2000) that proved that the accuracy of flashbulb memories deteriorates and distortions increase over time, and discussing a study by Talarico and Rubin (2003) that confirmed that flashbulb memories are remembered with no more accuracy than a normal everyday memory, it is clear that flashbulb memory is not reliably accurate when it comes to recalling details of past events because many details have the potential to be forgotten. In future it is recommended that wider age range and an equal number of male and female participants are used to get a reliable cross-section of the general population.

What Psychological Research Has Told Us about the Accuracy of Eyewitness Testimony L and P = Loftus and Palmer Pps = Participants EWT = Eyewitness testimony Despite the considerable importance juror’s place on EWT, psychological research has shown that EWT tends to be unreliable. This unreliability can be explained in terms of the reconstructive nature of memory (schema theory).
Memories can be altered based on acquisition, storage, and retrieval. Acquisition is what we notice or perceive based on what we are paying attention to. Storage is what information gets stored into one’s memory. Retrieval correlates with the false memory syndrome, which is recalling a previous traumatic experience that is false but believed to be true. The false memory syndrome is often noticed during police interrogations and leads to coerced confessions, which is when the individual being interrogated is essentially pressured to confess.
The special mechanism approach to flashlight memories was also introduced by R. Brown & Kulik, it stipulates that flashbulb memories are virtually literal representations of the what, how, and where of the original event (Schwartz, 2013). This mechanism works by encoding what happened in great detail. As a result, the flashbulb memory will be very strong and will remain in the memory (Schwartz, 2013). Strong emotions are the core of special mechanisms. To further explain, distinctiveness may be correlated with the critical triggering condition, experiences that produce strong emotional reactions may tend to be more distinctive than experiences that do not (Winograd & Nei...
Have you ever experienced an event that was so significant to you that you felt as if your memory was taking a photograph, keeping the memory implanted in your brain for the rest of your life? This is a prime example of flashbulb memory. Flashbulb memory is a term that pertains to a person’s memory of hearing about extremely shocking events (Goldstein, 2011, p. 209). Flashbulb memory is not the memory for the event itself, but it’s the memory of how the person heard about the specific event (Goldstein, 2011, p. 209). This means that a flashbulb memory includes where you were and what you were doing when you found out about a tragic event (Goldstein, 2011, p. 209). Some key attributes of flashbulb memories are that they are both remembered for long periods of time and are exceedingly vivid (Goldstein, 2011, p. 209). A great way to describe flashbulb memories is to compare them to a photo that never fades, proving how relevant these memories are to those who have them (Goldstein, 2011, p. 209).
Memory plays a large role in our legal system. A person who witnesses a crime has to rely on recalling information, which isn’t always completely accurate. In Johnson (1993) paper she discusses ways memory interferes with the legal systems and what rules and regulations help prevent memory failure to interfere.
The article How to Tell If a Particular Memory Is True or False by Daniel M. Bernstein and Elizabeth F. Loftus, addresses the various techniques used by cognitive scientists and other researchers in hopes of distinguishing true from false memories. For this article Loftus and Bernstein, memory researchers, chose to discuss the different methods currently used, rather than trying to find new ways to tell if a particular memory is true or false. Their findings in these three different approaches are very interesting, and leads us to think critically of the veracity of true and false memories.
A defendant’s guilt is often determined in a single moment of fleeting emotion. A pointed finger, accompanied by the solidifying eyewitness statement “He’s the one!” is enough for a jury to make its final decision in a court case. Although it is understandable, when faced opposite of the individual creating the accusation, to place one’s belief in the accusation made, the credibility of the eyewitness’s account of events are rarely taken into consideration. Psychologists have taken part in research that recognizes the unreliable nature of eyewitness statements used to determine guilt because of the instability of long term memory acquisition and because of this, eyewitness accounts of situations should not be used before a jury in court.
Researchers did this by testing four groups with the same criteria as the previous study, a control group and continuous, repressed, recovered memories groups of CSA. During this test, participants were given a word and must state a memory of an event that occurred no longer than one day in one minute or less. Half of the word cues were prompted to respond to a memory from childhood and the other half a memory from adulthood. Participants were then asked to report the date that the event occurred. The latency to retrieve a memory was recorded and used as a dependent variable. Although all four groups retrieved adulthood memories with ease, results revealed that all three groups with memories of CSA had difficulty in retrieving childhood memories. The repressed memory group performed significantly worse in the retrieval of these specific childhood
In recent years there has been a hot debate between "repressed" vs. "false" memories. Neurobiological studies show that both suppression and recall and the creation of false memories are possible. This paper evaluates the evidence but forth by both sides of the controversy and concludes that both are feasible and separate phenomenon, which occur at significant rates in our society.
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...
Memory is the tool we use to learn and think. We all use memory in our everyday lives. Memory is the mental faculty of retaining and recalling past experiences. We all reassure ourselves that our memories are accurate and precise. Many people believe that they would be able to remember anything from the event and the different features of the situation. Yet, people don’t realize the fact that the more you think about a situation the more likely the story will change. Our memories are not a camcorder or a camera. Our memory tends to be very selective and reconstructive.
The findings of this research would reinforce findings of previous research specifically in relation to the robustness of false memories. The experiment undertaken by students will also be helpful to the study of false memories specifically to test the reproducibility of this type of experiment.
According to Sternberg (1999), memory is the extraction of past experiences for information to be used in the present. The retrieval of memory is essential in every aspect of daily life, whether it is for academics, work or social purposes. However, many often take memory for granted and assume that it can be relied on because of how realistic it appears in the mind. This form of memory is also known as flashbulb memory. (Brown and Kulik, 1977). The question of whether our memory is reliably accurate has been shown to have implications in providing precise details of past events. (The British Psychological Association, 2011). In this essay, I would put forth arguments that human memory, in fact, is not completely reliable in providing accurate depictions of our past experiences. Evidence can be seen in the following two studies that support these arguments by examining episodic memory in humans. The first study is by Loftus and Pickrell (1995) who found that memory can be modified by suggestions. The second study is by Naveh-Benjamin and Craik (1995) who found that there is a predisposition for memory to decline with increasing age.
The findings of Timothy A. Allen along with Norbert J. Fortin, and Erika Hayasaki, reveal further insight into the role episodic memory plays in everyday life for humans. Episodic memory can be understood as memory for personal experience. Episodic memory is a type of long term memory that individuals are consciously aware of; making it an explicit memory. With that being said, this type of memory allows people to relive and re-experience memories from their personal past in their mind. This is why many refer to episodic memory as mental time travel. Through mental time travel, individuals are able to recall the circumstances under which they encountered specific experiences. Circumstances can include concepts such as what, where, and when an experience happened. Given the power that this form of memory provides, it is argued that
