The study tested the recall of candidates directly after exposure to a list of words and compared the results with the candidates given a delay and/or distraction between exposure and recall. Milner (1966) also supported the model, he verified the clear distinction between the LTM and STM shown in the multi-store model with his report into a patient whose memory was affected after having brain surgery. The patient was unable to make any new long-term memories, but was able to recall memories from his LTM store that had been developed before the surgery, therefore concluding that the two are separate
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.
Its purpose is to organize the information received from the other components with information about time and order.

A model of memory is Atinson and Sriffrins 1968 multi- store model of memory. The multi-store model of memory shows that memory goes into seperate stores, first being the sensory memory where the sense organ picks up the sense, through iconic and echoc storage ecoding, the duration of the sensory memory is incredibly short of only lasting between a 1/4 and a 1/2 of a second. if attented to, the information from the sensory memory will pass to the short term memory. Once in the short term memory, the information is encoded mainy auditory and the duration is very short, with it only lasting about 0-18 seconds. its said that the capacity of stm is 7+-2 chunks, as millers study 1956 showed as showed the stm could hold approximatley 7 chunks of information at one time.
Its cause is still unknown and medical researchers are still in the progress of the discovery. A number of doctors believe it’s a gathering of all of the sensory stimulation from the day, which begins to overcome and cause stress in some people. The correct cause of sundowner’s dementia is not known, professionals suppose there are numerous causative factors. These include
To what extent does the Multi Store Model offer a reasonable account of human memory? The Multi Store Model was designed by Atkinson and Shiffrin in 1968. The model proposes there are three different memory stores: sensory memory, short term memory and long term memory. Information from the environment is constantly received by the sensory memory store; most of it being irrelevant information. However if the information receives attention, it will pass on to short term memory.
Outline and evaluate the multi-store model of memory. The multi-store model of memory was created by Atkinson and Shiffrin in 1968. It consisted of three stores: the sensory store, the short term store and the long term store. The sensory store is where stimuli from the external environment first register; it holds information for fractions of a second after the physical stimuli is no longer available. Atkinson and Shiffrin then proposed three separate sensory stores to accommodate different kinds of input: -Iconic store for visual input -Echoic store for auditory input -Haptic store for tactile input.
(2) 3. Explain one limitation of the multi-store model of memory. (2) 4. Describe one way in which psychologists have investigated the duration of short-term memory. In your answer, you should include details of stimulus materials used, what participants were asked to do and how duration was measured.
The multistore model consists of three memory stores: sensory memory (SM), short term memory (STM) and long term memory (LTM) that is used for different tasks. SM is a storage system that holds information in a relatively unprocessed form for fractions of a second after the physical stimulus is no longer available – stores sensory characteristics of a stimulus and plays a vital role in filtering out useless information, enabling us to focus our attention on important details. STM is a limited capacity memory system for storing information for brief periods of time. Atkinson and Shiffrin (1968) see STM as a temporary storage depot for incoming information after it recieves and encodes information from the sensory memory. LTM holds a vast quantity of information, which can be stored
“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.
