However if the information receives attention, it will pass on to short term memory. The information held in short term memory is in a fragile state. The information is rehearsed and the information stays since it is in the 7+-2 capacity for short term memory. By maintenance rehearsal, the information can be transferred to long term memory. In long term memory there is a much larger capacity and the duration is possibly lifelong.
Structure of the multi-store model According to the multi-store model of memory (Atkinson & Shiffrin, 1968) memory can be explained in terms of 3 stores (sensory store, short term store and long term store) and 2 processes (attention and rehearsal). Information first enters the sensory store (also known as sensory memory) directly from the senses. It remains in the sensory store for a maximum duration of around 2 seconds before it decays and is replaced with new information. If information in the sensory store is attended to then it can be passed to the short term store. Around 7 plus or minus 2 chunks of Information (Miller, 1956) can be stored in the short term store (also know as short term memory).
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. The main characteristics of the Short Term Store are its size, which is limited and can only store up to seven pieces of information (plus or minus 2) at a given time, its duration, which is less than thirty seconds, and its encoding, favouring acoustic sounds (recognising information by how its sounds). The main and contrasting characteristics of the Long Term Store are again its size, which is unlimited, its duration, which is a lifetime, and its encoding, favouring semantic forms (recognising information by its meaning). The theory of the Multi Store Model claims that the memory consists of two separate storage areas. Glanzer and Cunitz (1966) came up with the theory of the “Serial Positioning experiment”.
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.
Learning activity 6.7 1. Short term memory (STM) is a memory system with a limited storage capacity in which information is stored for a relatively short period of time, unless renewed in some way. 2. The storage capacity of the STM is very limited. It has the capacity to hold 5 to 9 units of information at any one time.
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.
With reference to relevant research discuss the extent to which models of memory and theories of forgetting explain human memory. This essay will analyse the effectiveness of the multi-store model of memory and the working memory model together with examination of Trace Decay and Displacement theories of forgetting, as effective methods for explaining human memory. Memory can be defined as the minds storage system for information or experience (Gross 1996). The multi-store model of memory developed by Atkinson and Shiffrin (1968/1971 as cited in Gross, 1996; Cardwell, Clark and Meldrum, 2004) is a linier diagram with three stores; the sensory store, short-term memory (STM) and long-term memory (LTM) stores. Entailing of information flowing in a fixed sequence from one to the next.
KF showed very poor digit span (usually less than 2 items), but good performance on tasks that seemed to indicate an intact long-term store. For example, he was still able to store new information. In fact he could learn a 10 word sequence in fewer trials than normal controls and still retained seven of the 10 items some months later. The multi-store model predicts that this should not be possible since an intact STM is required to transfer information to LTM. We have enormous amounts of information in LTM even though we have probably not rehearsed much of it.
Multi-store Model of Memory The Multi-Store Model of Memory is a study of memory and explains how the memory works. Atkinson and Shriffrin (1968) suggested that memory comprised of three separate memory stores, the Sensory memory (store), the Short Term Memory (STM) and the Long Term Memory (LTM). The Multi-Store Model also shows the processes by which the information is passed to each store. The model suggests that human memory involves a sequence of these three stages. Information passes through each stage/store by control processes.
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.
