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 …show more content…

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
