- The nature of memory: Capacity and encoding
- Capacity of short-term memory
- The capacity of STM can be assessed by using digit span technique.
- Joseph Jacobs (1887)
- Increasing the capacity of STM
- The magic bumber 7 add or minus 2.
- The size of chunk matters.
- The size of the chunk affect how many chunks you can remember.
- Simon (1974)
- George MIller (1956)
- The capacity of STM may be even more limited.
- Cowan (2001)
- Vogel et al. (2001)
- The capacity of STM can be assessed by using digit span technique.
- Encoding in STM and LTM
- We can compare the ways information is stored in STM and LTM in terms of the encoding of the memory.
- Acoustic coding involves coding information in terms of the way it sounds.
- Semantic coding involves coding informatio in terms of its meaning.
- Baddeley (1966a and 1966b)
- LTM and STM may sometimes use other codes.
- In general, STM appears to rely on an acoustic code for storing information.
- However, some experiments have shown that visual codes are also used in STM.
- Brandimote et al (1992)
- Wickens et al. (1976)
- However, some experiments have shown that visual codes are also used in STM.
- Research has also shown that encoding in LTM is not exclusively semantic.
- Frost (1972)
