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. It can be an auditory or visual trace. If attention is paid to the information, it is then transferred to short-term memory where it is stored briefly. The short-term memory receives and retains only a small amount of information where it receives minimal processing. The transfer of this information between the stages may require re-coding. The memory traces in shorty-term memory are fragile and can be lost within 30 seconds through displacement or decay, unless rehearsed. This then creates long-term memory, where it can remain for a lifetime, although loss is possible from this store by decay, retrieval failure or interference. Long-term memory has unlimited storage, and is split into two memories Procedural memory which is a knowledge of how to do things and skills. Declarative memory is a memory for specific information or facts, which can be sub-divided into Semantic storage for language and general knowledge. This is the kind of memory that is tested in experimental work. The other sub-division is Episodic which is storage for personal events and people. This memory may not be reliable because of memory distortions. In 2000 Schachter et al. added another long term memory store called perceptual representation system which is a store for the likelihood of recognising something when you have recently seen something similar. The evidence for separate memory
