Duration, Capacity and Encoding
- Duration
- Peterson & Peterson (1959)
- - aimed to find the duration of STM
- - method: 24 participants, trigrams, displacement activities
- - results: 90% accuracy at 3 secs, 2% accuracy at 18 secs
- Strengths
- - simple nature of the experiment makes it easy to identify the
- effect of the IV (time delay) on the DV (recall)

- Weaknesses
- - ecologically invalid: don't usually have to remember such artificial data
- and if an item has meaning we're more likely to remember it
- - could be claimed that they were not testing duration but displacement

- - aimed to find the duration of STM
- Nairne (1999)
- - aimed to find the duration of STM
- - method: trigrams, no displacement activities
- - results: STM can last for as long as 96 secs without

- Bahrick et al (1975)
- - aimed to demonstrate duration of LTM
- - method: asked people of varying ages to put names to faces
- in their old school yearbooks
- - results: 48 years on, people were 70% accurate

- Peterson & Peterson (1959)
- Capacity
- Jacobs (1887)
- - aimed to find the capacity of STM
- - method: digit span
- - results: 9.3 numbers, 7.3 letters
- - results: 9.3 numbers, 7.3 letters
- - method: digit span
- - aimed to find the capacity of STM
- Jacobs (1887)
- Encoding
- Baddeley (1966)
- - aimed to find the different ways in which
- memory is encoded
- - method: participants given a list of words with similar
- sounds (cat, mat, etc.), a list of words with similar meanings
- (big, large, etc.) or lists of semantically and acoustically dissimilar
- words.
- - results: in the short term, more mistakes with acoustically similar
- and in the long term, more mistakes with semantically similar
- - conclusion: STM = encoded acoustically
- LTM = encoded semantically
- LTM = encoded semantically
- - conclusion: STM = encoded acoustically
- and in the long term, more mistakes with semantically similar
- - results: in the short term, more mistakes with acoustically similar
- words.
