Evaluation of Two Models Of Memory
In this essay 2 models of memory will be described and compared. They are the Atkinson and Sniffrin model of memory, the Multistore model, and Crain and Lockhart model, the Levels of Processing Model. Models of memory are primitive diagrams of human memory to help understand the flow of information and how it is stored. In order to evaluate those 2 models appropriately it is important to understand how old they are.
The Multistore Model of Memory by Atkinson and Shiffrin is a very primitive model although it does try to explain how the memory works quite well. It recognises 3 memory stores – the Sensory Memory Store, the short-term memory store and the

The presence of the short-term memory store and the auditory encoding is supported by the experiment conducted by Conrad in 1964, where he showed participants sequences of letter at random in a rapid succession, and relied on errors made to create his conclusion. He found out that the majority of errors involved a substitution of a letter by another letter of a similar sound. However, it is very easy to lose the information due to decay or displacement. Displacement means that new information pushes out the old information as the capacity of the STM is very limited; researched by Miller in 1956 it is supposed to be 7 items plus or minus 2. For example, you are processing the words you read on the screen in your STM. However, if I ask, "What is your telephone number?" your brain immediately calls that from long-term memory and replaces what was previously there. Decay is similar as the information disapperas as time passes by as the duration of STM is limited. Chunking can increase the capacity of short-term memory. For example, the letters "b d e" constitute three units of information while the word "bed" represents one unit even though it is composed of the same number of letters. Chunking is a major technique for getting and keeping information in short-term memory; it is also a type of elaboration that will help get information into long-term memory. Subvocal

According to philosopher-psychologist William James, memory is a generalized concept that encompasses the long term and short term memory. Kendra Cherry, psychologist expert, defines long term memory as “storage of information over an extended period.” (Cherry n.d.) An individual’s long term memory is structured by a semi-permanent chemical and the anatomical hippocampus. The hippocampus is in the center of both hemispheres of the brain and works in accordance with the amygdala to allow information to be imported to form memories. In relation to her research of the long term memory, Cherry also provided information on the characterization of the short memory which is described as, the “primary or active memory” that presently takes in information. (Cherry n.d.) The thalamus is a large portion of a dual lobed mass of matter that is located under the cerebral cortex.
Memory retention is essential to all human beings. It is a fundamental function of our brain: whether it be memorizing people’s names, memorizing math formulas, or memorizing the location of the car keys. We all recognize the importance of memorization and we all seek ways to improve our memory retention skills.
How is memory encoded and what methods can lead to greater recall? There have been many different models suggested for human memory and many different attempts at defining a specific method of encoding that will lead to greater recall. In this experiment subjects are asked to do a semantic task on a word related to them and an orthographic task in which they analyze the letter in the word. The results of the experiment indicate that the words which where encoded semantically and are related to the self have greater recall.

Memory is a set of cognitive processes that allow us to remember past information (retrospective memory) and future obligations (prospective memory) so we can navigate our lives. The strength of our memory can be influenced by the connections we make through different cognitive faculties as well as by the amount of time we spend devoting to learning specific material across different points in time. New memories are created every time we remember specific event, which results in retrospective memories changing over time. Memory recall can be affected retrospectively such as seeing increased recall in the presence of contextual cues or false recall of information following leading questions. Memory also includes the process
There are possibly other answers if we continue to look at multiples of 7 and repeat the process.
Stanislaw Jerzy Lec once said “You can close your eyes to reality but not to memories.” Stanislaw Jerzy Lec’s quote relates to the theme of the importance of memory by saying that reality can fade away however memory will always stay in your heart no matter what. Scrooge knows this however doesn’t see it until the Ghost of Christmas Past shows him his past memories of Christmas. For example, the Ghost of Christmas Past shows his first Christmas all alone in his old school’s room as a child. As well as when Scrooge is shown his past Christmas with his family for the first time since his father had changed. Lastly when he enjoys his Christmas with his friends from his work with their annual Christmas party and has a wonderful time. “The Christmas Carol” displays the importance of memory.
The Evidence for the Existence of Multiple Memory Systems Memory forms an important part of cognitive psychology and has been of interest to numerous psychologists. This essay is going to refer specifically to the information-processing model of memory and will discuss the experimental evidence that exists for multiple memory systems. The multi-store model of memory was first developed by Atkinson and Shiffrin (1968) and Waugh and Norman (1965).[1] It comprises sensory stores, short term-store and long-term store to form a model of memory and information processing. One component of the system is the sensory register, where our feature detection and pattern recognition processes produce a
Richard F. Thompson was a memory scientist who conducted research on where and how memory is stored and transformed in the brain. He conducted research on the cerebellum, which is a lower brain structure that deals with physical movement, to see how reactions are created and reestablished every time a certain thing happens, which is basically a reflex (Hockenbury, Nolan, & Hockenbury, 2016). His research was to study how a basic function reflex occurs, and how the memory knows to react when something occurs again in the same manner. Thompson succeeded in his research, by conducting an experiment with rabbits and their blinking reflexes (Hockenbury, et al., 2016). He designed a way where rabbits would react to a tone in where they would blink to it (Hockenbury, et al., 2016). He then took an extra step away from the brain, and the rabbits would still react in the same way to the tone, which lead him to discover that the main memory function is stored in the cerebellum (Hockenbury, et al., 2016).
Although visual art is looked upon differently by all, everyone has a either a favorite piece or at least something that catches their eye. Personally, I don’t have a piece of art that I would label my absolute favorite, but during a Spanish research project found that Salvador Dali’s work really stood out. “The Persistence of Memory” painted in 1931 by Dali, a highly renowned surrealist painter, is among the most interesting works I have ever seen. Even though the painting itself is rather simple in quality at first glance, what Dali’s must have been thinking about while creating this work is strikingly complex. The painting is attractive to me because it deals with the concept of time, something

In daily life, memory is used all the time. When we go to buy things, we would remember the list of items what we are going to buy. At school, we would also need to have revision in order to remember the materials for examination. Or even, when we meet friends, we would also need to recall their names. Thus it is important to know and understand how we remember such things so that we can effectively recall them when necessary. Obviously, we do not need to remember the exact position or order of things in daily life. We would have our own pattern for remember and retrieve information (Ashcraft, 2010). This is named as free recall, which items recalled in any order (Francis, Neath, MacKewn and Goldthwaite, 2004). However, many researchers
