Evaluate two models of one cognitive process This essay will be discussing one particular cognitive process: the memory by evaluating two models, which are the Multi store model introduced by Atkinson and Shiffrin in 1968 and the Working memory model by Baddeley and Hitch in 1974. The first model is the multi store model. It was first proposed by Atkinson and Shiffrin in 1968 and is a typical example of the information-processing approach. According to this model, memory consists of three types of memory stores: sensory stores, short-term store and long term store. Sensory stores consist of the eyes, nose, fingers, tongue, etc and the corresponding area of the brain. The sensory stores constantly receive information but most of this information receives no attention and remains in the sensory stores for a very brief period. If a person’s attention is focused on one of the sensory stores, then the data is transferred to short term store. By paying attention, we can remember. But information stored in short term store is easily lost; it will decay very rapidly if not rehearsed. Memory will also disappear if new information enters short term store and displacing the original information. This happens because the short term store only has a limited capacity. The second step is moving info from short term store to long term store. Initially rehearsal maintains memory in the short term store but constant rehearsal helps memories last longer. In short, the more the information is rehearsed, the better it is remembered. There are some evidences that support the multi store model. For example brain damaged patients. The case study of HM had proven that the hippocampus may function as a memory gateway through which new memories must pass before entering permanent storage in the brain for anything that happened since. This proven that memory must go through the short term store in order to be able to move to the
