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. Atkinson and Shiffrin (1971) added to the model the process of transfer from the STM to the LTM store. Termed as rehearsal, they demonstrated that the STM could be expanded from its unaided duration of 15 and 30 seconds when aided by repetition and rehearsal (Gross 1996). One of the many studies that support the multi-store model is the recency effect study by Glanzer and Cunitz (1966); they concluded that the STM and LTM are separate stores from each other (Eysenck and Keane, 2002). 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
