...Memory is very complex in ways that we encode, store, and retrieve events that occur in our life. Even though flashbulb memory allows individuals to recall events in detail, there are distortions of the memory that may cause individuals to think certain details occurred when it actually did not. Through analysis of my memory and determination of what causes flashbulb memories, I can determine if my memory is a flashbulb memory, and if detailed were fabricated within that...

...An example of a cognitive process is memory, remembering things. Flashbulb memories (FBM) are highly detailed, exceptionally vivid ‘snapshots’ of the moment and circumstances in which surprising and consequential (or emotionally arousing) events happened or news was heard. Brown and Kulik (1997) who were the first modern psychologists to study FBMs, defined them as ‘memories of the circumstances in which one first learned of a very surprising and consequential (or emotionally arousing) event’. The defining feature of an FBM is not the memory of the event, but memory of its reception context- the circumstance of the news’s reception. Brown and Kulik proposed a theory of the formation and the maintenance of FBMs. FBMs form in situations where...

...MEMORY ACCURACY: THEORETICAL MODELS AND EXPERIMENTAL VALIDATION Human memory has been on many occasions compared to the operations of a computer on the basis of their multifunctional systems. Memory is critical and plays a central role in our everyday information processes. Several models of information processes have in-time being proposed. The Atkinson-Shiffrin model (1968) is the most popular is and widely used by many memory researchers. The model indicates the transfer of information from the environment into the sensory memory which is very brief that some information is forgotten before it reaches the second storage. Short-term memory is the second temporary store which is also fragile. The short-term memory is very similar to working memory responsible for higher cognitive functioning which is also temporary. Information is then finally encoded onto the long-term memory where it is assumed to be a permanent storage for longer periods. Baddeley (2000) proposed the episodic buffer as the new forth component of the working memory model. This model was initially proposed by Baddeley and Hitch (1974) with three components, the central executive assisted by the phonological loop and the visuo-sketchpad assumed to be temporary storage faculties. The episodic buffer is assumed to play a very central role of binding features into objects and it is assumed to be a temporary limited store which links all systems together for the purposes of multi-dimensional coding (Baddeley...

...crime and studying this unit, there is one trick for giving your memory a boost, Is to use mnemonic devices to encode items a special way. Three popular techniques is the Method of loci, peg words, and acronyms. There are other reasons for memory distortions, for instance epinephrine and cortisol are natural hormones in the body that affect the amygdale. The powerful effect of these hormones produce what is known as “flashbulb memories”, flashbulb memories are memories that are produced with surprising or emotional events in life. Another reason that could affect memory is the sleeper effect. The sleeper effect is like when students cram for a final the day before. Trying to memorize a lot of information at the same time really doesn’t help your memory it actually impedes it. You wouldn’t learn or remember as much unless you did a distributed practice which is spacing out you learning, you tend to retain more information a little bit at a time instead of trying to remember all at once. [4] If, I was a juror and I knew about this information then I would definite bring it to light, the fact that we create our own memories to make life more efficient. There are numerous ways that people forgot information without even realizing it. Elizabeth Loftus did studies on manufacturing memories to bring this topic to light because a lot of people were serving time in prison because of these types of memories. She did a study about people visiting Disney World and asks about what type of characters...

...reactions can lead to undue distress and be manifested in psychological disorders such post-traumatic stress disorder as well as anxiety disorders. One source of unwanted emotional reactions is memories of stressful or traumatic events. Past research has found that highly emotional memories can be difficult to forget, and can be frequently brought into conscious awareness without volition. Traumatic memories may well be remembered due to unique organizational and structural features in memory. Whether such memories lack proper coherence and organization, or whether they are overly integrated into the life story, stressful memories appear to differ from everyday memories their structure and organizational features. As a result, once a stressful experience has ended, the experience can continue to affect an individual through his or her memory of the event. In spite of the ongoing controversy surrounding how the organizational aspects of stressful and traumatic events differ from those of non-traumatic memories; most researchers agree that emotion is a central aspect of traumatic events. Many factors influence which moments from our past are remembered best, and the affect experienced during an event is an important contributor. “Flashbulb memories” which are events of emotional significance are more likely to be recalled vividly than mundane experiences, and neurobiological research has confirmed...

...RUNNING HEAD: SOURCE MEMORY AND THE IMPLICATION OF THE PAST, PRESENT AND FUTURE Memory has a multitude of facets that comprise what a memory is and how a memory is characterized. Some memories are recollections, hazy moving pictures; some are unconscious working memories, while others are a bit more in depth. A source memory is a type of memory in which we remember who, what, where, when and how of a specific event. It is what gives our memories relative meaning to both time and the significance of the events that occurred in our life. A memory is generally meaningful regardless, but when we can recollect the sources of that memory, it fine tunes the events surrounding it as well as future recollections. The ability to source our memories comes full circle within our lifetime, developing in early adolescence throughout early and late adulthood, and eventually the ability becomes more tasking for our cortex within old age. Time is one of life’s few constants, a never ending stream of information in this space-time continuum. The ability of our mind to capture moments of this past in an almost capsule like photograph is astounding, being able to source these times shows how powerful memory is and the capture of moments in this never-ending continuum. Myriads of studies on source memory have been conducted and more recently within the past few decades. The studies herein focus on various source memory tasks throughout age groups, examining the differences...

...model of memory (12 marks) Information from the environment is transferred through one of our five senses into the sensory memory (encoded depending on the type of information we receive). The sensory memory is a store suggested to be large in capacity but the duration the information is held for is the problem, lasting only fractions of a second. When attention is paid to information it enters the short term memory. According to Miller, the short term memory has a capacity of 7+-2 items. The duration of the short term memory last between 18 and 30 seconds, the STM is encoded mainly acoustically but sometimes visually. If maintenance rehearsal takes place it will remain in the STM or will be lost through decay or displacement. Elaborative rehearsal will then transfer information into the long term memory, which has an unlimited capacity and duration (without interference such as memory decay). The LTM encodes mainly semantically (through meaning). Information can be retrieved from the LTM to be used in the STM when needed. One strength of the model is that is it supported from clinical/empirical research based on real people rather than laboratory experiments. This makes it high in ecological validity and can be applied to everyday life within the real world. For example, the study of HM, a brain damaged patient underwent an operation to cure a severe case of epilepsy but this resulted in the ability to transfer from the STM to the LTM, HM could not form long term memories and could...

...multi-store model of memory The multi-store model of memory is a representation of the flow of information through the memory system. The information first flows through the sensory memory, then the short-term memory, and then the long-term memory. Information is detected by the sense organs and enters the sensory memory. If the information is not given attention then it is forgotten through trace decay. If the information is given attention then it goes to the short-term memory. If you repeat the information then it stays in your short-term memory due to the process of maintenance rehearsal. This means that if the information is repeated then it stays refreshed in our minds. But items can also be forgotten in the short-term memory due to displacement. This is the process by which items in the STM are pushed out to make room for incoming new ones. However, if the information has remained in the STM due to maintenance rehearsal and links are made, then the information is transferred to the long-term memory through the process elaborative rehearsal. Making links is when you subconsciously compare information to something you have seen before therefore making it easier to remember. When you think of a memory then you retrieve it from your LTM and bring it to your STM. This is called retrieval. Each part of the multi-store model of memory has a different amount of capacity, duration and encoding. The capacity is the amount of information that can be held in a memory store, for example...

...Witnesses rely on their memories to testify as to what they believe is a true account of the event. However, memories have been found to be fallible with no guarantee of corresponding with objective reality (Johnson, 2001). Research has found that false memories (FM), where a person recalls an event that did not occur and mistakes it to be a true representation of that event (Gleaves & Smith, 2004; Johnson, 2001) exists within the realm of eyewitness testimony (ET) (Loftus, Miller & Burns, 1978). This raises the issue of how well does ET reflect reality. Some theories that explain FM include the source monitoring failure theory (Johnson, Hastroudi & Lindsay, 1993), activation monitoring theory (Roediger, Balota &Watson, 2001) and fuzzy trace theory (Brianerd & Reyna, 1998; Reyna & Brainerd, 1995). Due to word count limitations, this paper will explore the concept of FM using fuzzy trace theory, source monitoring errors and the misinformation effect to explain how FM occurs in the context of ET and why ET can never the representation of the complete truth. The FTT proposes that there are two parallel memory traces, the verbatim trace and the gist trace (Brianerd & Reyna, 1998; Reyna & Brainerd, 1995). The verbatim trace stores information item-by-item and is a verdicial representation of an event. The gist trace stores a generalised meaning based representation of an event. The FTT proposes that verbatim trace decays quickly whereas the gist trace lingers in memory longer resulting...

... The effect of Word Processing on Memory ability Tutor: Mary Christopoulou Student: Panagiotis Moschonas Submission Date: 25/3/13 The effect of Word Processing on Memory ability Many researchers have done experiments or had conducted studies about the memory and our ability to storage information inside our brain and recall them when we need them. We divide our memory in three “pieces” the short-term memory and the long-term memory and the sensory memory. This memory model was explained by the researchers Atkinson and Shiffrin 1968. First is the sensory memory, it can memorize things only for a few seconds. The visual system possesses iconic memory for visual stimuli like the shape, the size and the color of an object. Second is the short-term memory, in this case we can store some information for a longer period so that we can be able to use them for example we can memorize a telephone number long enough to dial it and use it, after that we are giving away the information if we don’t need it. According to Peterson & Peterson (1959) the duration of the short-term memory is approximately fifteen to thirty seconds. The third one is the long-term memory, which is the type of memory that makes us remember information from the minute that we learn something for the rest of our lifetime. Some memories may be stored from sensory...
