Multi-Store Model of Memory The multi-store model is the explanation for how memories are processed. It explains why only a few things are remembered and why some things are remembered and others aren’t. Atkinson and Schiffrin were the first to describe the multi-store model. They designed a simple diagram to show the multi-store memory: Sensory memory Environmental Stimuli Attention Short-term Memory Maintenance Rehearsal Information Retrieval Elaborate Rehearsal Long-term Memory Retrieval Sensory memory Environmental Stimuli Attention Short-term Memory Maintenance Rehearsal Information Retrieval Elaborate Rehearsal Long-term Memory Retrieval The Multi-store Model has 3 different places for memory storage. Information passes from store to store in a linear way and there are different explanations for forgetting in each store The first store is where sensory memory is processed.
earsal is the process of repeatedly verbalizing, thinking about, or otherwise acting on information in order to keep that information in memory. Maintenance rehearsal is the repetitive review of information with little or no interpretation. Elaborative rehearsal involves repetition in which the stimulus may be associated with other events and be further processed. Elaborative rehearsal exists in the encoding of information within long term memory. Maintenance rehearsal alone is not sufficient for information to be transferred into long-term memory and permanently stored.
12 marks The multi store model of memory was created by Atkinson and Shiffrin in 1968. Their findings showed that information first enters into the sensory memory which is very short lived. The sensory memory can be produced in two ways Iconic (visual) or Echoic (auditory). When the information has caught the attention of the brain it enters the short term memory which lasts for up to 20 seconds this was discovered in an experiment by Psychologist Peterson in 1959. In addition information in the short term memory store is encoded acoustically; this theory is supported by Conrad’s 1964 case study where an experiment was conducted that confirmed Atkinson and Shiffrin’s theory that the STM encodes information acoustically.
Discuss the value of the Multi Store Model of memory (12 marks) The MSM of memory consists of four main components: the Attention System (Sensory Store), the Short Term Store (often known as the working memory), the Rehearsal Loop and the Long Term Store. The Attention System filters incoming information. If this information is paid attention to, it gets transferred into the Short Term Store. However, if the information is not acknowledged it is lost/decays. The Rehearsal Loop allows the rehearsal of information resulting in it being transferred into either the Long Term Store, or due to maintenance rehearsal, the information will be able to stay stored in the Short Term Store.
Describe and evaluate 2 models of memory. The Multi-Store Model (MSM). The multi-store model which is also known as Atkinson-Shiffrin memory model which was first recognised in 1968. The model identifies three stores: Sensory memory, Short-Term memory and Long-Term memory and it explains how information is transferred between these stores. The information enters the sensory memory model which is stimulated by the sensory form which remains unaltered in the mind for a brief time before decaying.
The long term memory stores unlimited amount of information for a lifetime through semantic encoding. However, it may be forgotten because memory traces can decay, ‘new’ information which causes confusion and interferes with the old information or particular cues within the environment are not available causing retrieval failure. Many investigations/ experiments/ case studies have been undertaken to test the Multi-store memory model. This essay will give both the strengths and weaknesses of the MSMM. Peterson and Peterson investigated the duration of the Short Term Memory in 1959.

In your answer, you should include details of stimulus materials used, what participants were asked to do and how duration was measured.
There are many different memory models, and the most famous ones are the MSM and LOP. MSM contains three levels: sensory store, short-term store, and long-term store. What is important in this model is the duration of time, recalling and retrieving information, so it can move from one store to another. In the LOP it’s about the levels of processing where there’s three levels each at a deeper level than the previous, and the levels are:
Outline the multi-store model and working memory model The multi-store model of memory is when information appears in Sensory Memory if attention is given to this it transfers to Short Term Memory, if the information is then rehearsed; it appears in the Long Term Memory. If at any time attention or rehearsal is not given to the information the trace decays and so because of this, we forget, however this need for rehearsal for transference into the Long Term Memory has been criticised as some information can be retained without any form of rehearsal. Within the multi-store model of memory, both Long Term Memory and Short Term Memory differ from each other in various ways; the duration of short term memory is 18 seconds, where as the duration of long term memory is a lifetime. The capacity of short term memory is found to be 7 + OR – 2, compared to long term memory’s unlimited capacity. As far as coding is concerned, there are also differences between short term and long term memory; short term is acoustic and long term is semantic.
“The ability to recollect past events and to bring learned facts and ideas back to mind.” (Foster, 2002) Types of Memory According to the Multi Store Model of Human Memory proposed by Atkinson and Shiffirin, memory is of three different types: (Atkinson & Shiffrin, 1968) 1. Sensory Memory: Based on the principle of Dual Channel, visual and auditory information enter the sensory memory through separate, independent channels (Low & Sweller, 2014). Though the capacity of the sensory memory system is infinite, the information is only held for 0.25-2 seconds. The information which is brought into our awareness or gains our attention is passed on to the Working Memory System, the rest is lost. 2.
