Describe and evaluate the multi store memory model Atkinson and Shiffrin 1968 suggested that memory was comprised of three separate stores - the Sensory Memory store‚ the Short-term Memory store‚ and the Long-term Memory store. Information from all around us enters the through the sensory memory and encoded through one of the 5 senses depending on the type of information. If attention is paid to this information it will enter short term memory which has a limited capacity of about 4 chunks of

Multi-store Model of Memory The multi-store model of memory was proposed by Atkinson and Shiffrin in1968. The model consists of three separate stores – the sensory store‚ the short term memory and the long term memory. Information enters via our senses (sight‚ smell‚ sounds‚ taste and touch) into the sensory store. We pay attention to some of the things that enter our sensory store‚ these things them move on into our short term memory. Whatever is stored in the short term memory is only temporary;
Premium Memory
Memory is the ability to encode‚ store and recall information. The three main processes involved in human memory are therefore encoding‚ storage and recall (retrieval). Additionally‚ the process of memory consolidation (which can be considered to be either part of the encoding process or the storage process) is treated here as a separate process in its own right. Encoding is a biological event beginning with perception through the senses. The process of laying down a memory begins with attention

Narrative Chaining & Enhancement of Memory Introduction Memory is the ability to store and retrieve previously learnt information. Memory can be described using a variety of models.

is nothing more haunting than memory repression. First‚ the mind hides a shocking event in a dark corner of the unconscious. Later‚ the memory may rise into consciousness. Then all hell break loose. During the 1990s‚ there has been a rise in reported memories of childhood sexual abuse nased on repressed memory.
