- The Multi-store Model of Memory
- Outline
- Short term memory
- Capacity: 7 +/- 2 items
- Study: Miller (1956)
- Duration: 18-30 seconds
- Study: Peterson & Peterson (1959)
- Encoding: accoustic
- Study: Conrad (1964)
- Capacity: 7 +/- 2 items
- Sensory memory
- Capacity: very little
- Duration: 0.25 seconds
- Encoding: sensory
- Long term memory
- Capacity: unlimited
- Duration: up to a lifetime
- Study: Bahrick et al (1975)
- Encoding: semantic
- Study: Baddeley (1966)
- Short term memory
- Evaluation
- Advantages
- There is a general agreement that there is a STM/LTM distinction
- Useful model based on empirical evidence
- Many subsequent theories derived from it
- Disadvantages
- Reductionist:the model is over simplified
- Doesn't consider more complex processes
- Research shows that rehearsal is not essential for the transferral of information from STM to LTM.
- E.g. we may remember things if they are funny or meaningful
- Rehearsal can often be a very bad strategy for memorising information
- Britain (late 1970s): the BBC introduced new radio frequencies. Despite the policy of saturation (most people heard the information literally hundreds of times) they still did not retain the information.
- Suggests that passive rehearsal was not adequate to transfer information into the LTM.
- Britain (late 1970s): the BBC introduced new radio frequencies. Despite the policy of saturation (most people heard the information literally hundreds of times) they still did not retain the information.
- Reductionist:the model is over simplified
- Advantages
- It is an attempt to explain how information flows from one storage system to another.
