Outline and evaluate an alternative to the Multi-store Model of Memory
There are many different explanations as to how we remember things. One of the most basic is Atkinson and Shiffrin’s multi store model of memory. This indicates that you see things, then they go into your short-term memory, and then if they are processed they will go into your long term memory. One of the most important things that influences whether something goes into your long-term memory is rehearsal. If you rehearse things, for example, say things over and over again or keep it in your mind for a longer period of time, then it is more likely that it will go into your long-term memory.
Craik and Lockhart put forward the levels-of-processing theory, which is an alternative to Atkinson and Shiffrin’s Multi-store Model of Memory, because they felt that rehearsal wasn’t enough to get data from STM into LTM. This theory states that the depth of processing of an item has a big effect on its memorability, e.g. how well you remember the item. They said that when items are deeply or semantically processed, it means you can remember the item for longer, more elaborately and the memory is stronger. This is compared to phonemic and shallow processing where the memory is not as strong. The assumption of this is that in deep processing, the meaning of the word gets processed too, and this therefore leads to a better long-term memory of it. However, the meaning doesn’t get processed in shallow processing, therefore the long-term memory of it is poor, if there is any long-term memory of it at all. There are three other types of deep processing, these being elaboration (thinking more about the item), distinctiveness (unique things are easier to remember) and organisation. Strengths of the theory include the fact that it offers a model that can help you improve your memory e.g. if you can’t remember something, don’t just rehearse it, memorise the meaning of it. Also, before this theory was put forward, the view was that memory can be explained in terms of structure and rehearsal, so this theory had a major impact. However, there are some criticisms to this theory. For example, it doesn’t explain why deeper processing leads to better memory. It’s also hard to establish whether a particular task involves shallow or deep processing.
