Atkinson and Shiffrin (1968) suggested that memory is made up of a series of stores:
- Describes memory in terms of information flowing through a system.
- Information is detected by the sense organs and enters the sensory memory.
- If attended to this information enters the short term memory.
- The information is transferred to the long term memory if it is rehearsed.
- If information is not rehearsed, then the information is forgotten - lost from short term memory by displacement or decay.
- Duration: 0.24-0.50 seconds.
- Capacity: All sensory experience (very large)
- Encoding: Sense specific (different for each sense)
- Duration: 15-30 seconds.
- Capacity: 5-9 items.
- Encoding: Mainly acoustic.
- Duration: Unlimited
- Capacity: Unlimited
- Encoding: Mainly semantic.
Evaluation of the Multi-Store
- Many memory studies provide evidence to support the distinction between STM and LTM (in terms of duration, capacity and encoding).
- The model can…
