The Conversation Theory: The Decay Theory Of Memory

1196 Words5 Pages

Memory consists of the processes that enable us to record, store, and retrieve experiences and information. Humans are dependent on their memory; without the capacity to remember we could not have survived as a species (Passer, Smith, Holt, Bremner, Sutherland and Vliek, 2009). However, memory is not perfect - humans forget. This is partially due to its structure. Sensory memory and working memory do no retain information indefinitely, whereas long term memory does. Consequently, not all information reaches the long term memory, and if some does, difficulties in retrieving it may occur. The interference theory, the decay theory or the motivated forgetting theory all attempt to explain those retrieval impairments and will be presented below. …show more content…

(2009), long time memory is essentially unlimited, information stored in the long term memory is still susceptible to forgetting. One of the most influential theories regarding this issue is the interference theory. That is, we forget information because other items in the long term memory impair our ability to retrieve it (Postman and Underwood , 1973, in Passer, et al., 2009). This is directly linked to the similarity between the two (or more) items. The more similar the objects are, the higher the chances of interference rise. For example, if you watch two or more movies featuring Anthony Hopkins, it will be more difficult to remember the name of one of the movies than if you watch that movie alone. This is not simply due to the fact that there is more information for more films. What happens is that the 'featuring Anthony Hopkins' cue is common, and if this is the only cue to retrieving the desired information, no further distinction is possible between the movies. Confusion may result, and accessing the cue may attend the wrong memory. If you try to remember the name of the last movie with Anthony Hopkins you have watched, but the name of the first movie keeps on sounding in your ears, you experience proactive interference. The reversed process is known as retroactive interference (Passer, et al., 2009). But this is not the only view in the interference theory. A later view, endorsed by Wixted (2005), brings the theory …show more content…

Not using, not rehearsing certain information may lead to the deterioration of the physical trace in the nervous system (Passer, et al., 2009). The neural networks models relate directly to this theory, as they propose that memory hinges on connections between neurons, which form 'nodes', each node corresponding to a particular memory (Passer, et al., 2009). If those connections are not used, they fade. The effect is forgetting. However, there are objections to this theory. In some cases, individuals are able to recall perfectly information that was not used extensively. Musicians, for example, can play pieces that they haven not heard or practiced for years. Furthermore, this theory's prediction, that the longer the interval of disuse between learning and recall, the less should be recalled, is being contradicted the study of Bahrick, Hall, and Berger (1996), cited in Passer, et al.(2009). The study reveals that individuals who studied Spanish in high school typically display better knowledge of the language at 15 years since the completion of the Spanish course than at 3, 5 or 10 years since completion. Another disputed theory is that of motivated forgetting. This theory suggests that, at times, people are consciously or unconsciously motivated to forget unpleasant, embarrassing, anxiety-arousing memories (Passer, et

The story “Into Thin Air”, by Jon Krakauer, first starts with Jon Krakauer being 29,028 feet up in the atmosphere in the middle of his adventure as he and a few other groups from around the world strive to get to the top of the summit of Mt. Everest. The. While up into the atmosphere, Jon was having a hard time and suffering from the lack of sleep and food, along with a gruesome cough he had had for weeks, which also caused him to break two of his ribs. Later in the story, Jon starts talking about his process of beginning the expedition, joining Rob Hall’s company, and meeting his other group members. Rob Hall has guided many people to the top of the mountain and has claimed his company to be the “world leader in Everest climbing”.

The third part of this was a another scan while they were asked from memory to remember the pairs. They were not able to remember many of the pairs. The results showed that the test subjects were able to consciously repress the memory of the second word of the pairs. Proving that the brain is able to repress memories. Based on my research and my own opinions, I was able to ascertain from many accounts that a suppressed memory is most likely to resurface when an incident happens that slightly resembles what occurred of felt in the repressed memory.

The first piece of evidence in document 2 is “Imagine filling a bathtub with a thimble; that's the challenge involved in moving information from working memory into long-term memory.” This quote shows that it's hard to remember things when we're overwhelmed with too much information at once. The second piece of evidence from the document is “Psychologists refer to the information flowing into our working memory as our cognitive load. When the load exceeds our mind's ability to process and store it, we're unable to retain the information or to draw connections with other memories.” This shows that our ability to remember things is limited by how much our minds can handle at

How Memories shape humanity "Without memory, there is no culture. Without memory, there would be no civilization, no society, no future." – Elie Wiesel Memories are what enable us to learn from our past experiences, make educated guesses, and establish our own individuality. We couldn't learn, grow, or develop a sense of morality without memories. Hence, they form an important part of what makes us human.

Moreover, “a behavioural syndrome results showing not only semantic-memory impairment but also particular difficulty remembering past events as personal happenings” (Tulving, 1989). Lastly, in Endel Tulving’s conclusion to his article he states “traditionally held views about the unity of memory are no longer tenable. A more appropriate view seems to be that of multiple memory systems. Remembering one’s past is a different, perhaps more advanced, achievement of the brain than simply knowing about it” ( Tulving,

A well known study called the “lost in the mall” study shed some very interesting light on the subject of long term memory.. This study had patients being told 4 stories about their childhood, and they would be asked for as much information as they can remember about each of the stories, however, without them knowing, one of the stories was false

How reliable are the two models or theories of the cognitive process of memory, “|…|the process of maintaining information over time” (Matlin, 2005) , known as the multistore model (MSM) and the levels of processing model (LOP)? Both of these models have been widely criticized, but simultaneously they have improved our knowledge and understanding of how the process of memory works. In this essay both of these models of memory will be evaluated by presenting the strengths and limitations of each. The first model, the multistore model, was put forward by Atkinson and Shiffrin (1968) which suggests that the concept of memory involves three stores; the sensory stores, the short-term store (STS), and the long-term store (LTS).

The biological approach to the basis of memory is explained in terms of underlying biological factors such as the activity of the nervous system, genetic factors, biochemical and neurochemicals. In general terms memory is our ability to encode, store, retain and recall information and past experiences afterwards in the human brain. In biological terms, memory is the recreation of past experiences by simultaneous activation or firing of neurons. Some of the major biopsychological research questions on memory are what are the biological substrates of memory, where are memories stored in the brain, how are memories assessed during recall and what is the mechanism of forgetting. The two main reasons that gave rise to the interest in biological basis of memory are that researchers became aware of the fact that many memory deficits arise from injuries to the brain.

To start with the basis of understanding the memory, one must know that memories are stored in the hippocampus and prefrontal cortex. In a recent fMRI (functional magnetic resonance imaging) study over the past decade, researchers found that the hippocampus and prefrontal cortex have decreased in activity. The memory is a constructive surface and not so much reproductive. It can be distorted by being influenced by bias, association, imagination and peer pressure. As one goes to recall an event, the brain will now associate that memory with what is happening around them at the time of the recall.

If information stored in the short-term memory is not learned and given attention, it will decay over time (Schunk 2012, p. 183). The short-term memory has a small capacity, and large amounts of information cannot all be stored (Schunk 2012, p. 183). To make it esier, information can be shortened or broken up to fit it in the short-term memory (Schunk 2012, p. 183). Information that is used will be transferred into the long-term store/ long-term memory (Schunk 2012, p. 183). There are different strategies to strengthen the memory of information from short-term to long-term.

Introduction According to information processing model, short term memory has a limited capacity to hold information (Atkinson & Shriffin, 1968). The span of short term memory is said to be limited to about seven items (+2) (Miller, 1956 as cited in Terry, 2000). Short-term memory is also an active memory where we do our active memory processing (Lefrancois, 2000). For this reason, several researches have called the short term memory the working memory store (Gordon, 1989).
