The two-process model of memory

Extracts from this document...


The two-process model of memory Atkinson and shiffrins two process model distinguished between long term and short term memory. It stated that information coming into memory first goes into the short term memory, however there is a very limited amount of space in this area so this information is very quickly lost and forgotten, the information will only stay there between 15 to 30 seconds. A way of keeping this information a little longer is to rehearse i.e. saying a telephone number over and over in your head will make you remember it for longer. If this information is rehearsed enough it will travel further along down the line and get transferred into the long term memory, because of its large size information stored here can be kept from a few minutes to a lifetime. ...read more.


The short term memory usually uses acoustic encoding, such as repeating a telephone number out loud. Where as the long term memory usually uses semantic or visual encoding, i.e. remembering the meaning of something or what it looks like. Below is a diagram of how the two process model works. Evaluation of the two process model: There are many different good and bad points when it comes to evaluating the two process model of memory. Some of the strengths are that, it has been very influential and has helped to provide a widely used framework of study. ...read more.


People also argued that the STM is far more complex than the model suggests. The same problem arises with the LTM because the model does not account for all of the different types of long term memory, no does I distinguish enough between the different ways in which we rehearse information as it can be done in many different ways. Also a man by the name of Jenkins (1974)found out that rehearsal was not always needed in order to remember information. So all in all the two process model provided a good starting point for further research into the way in which our memory works but did not really go into enough detail to explain it fully.
