Research on Coding: researcher
Baddeley
1 of 13
Research on Coding: procedure
lists of words to remember (acoustically similar/dissimilar and semantically similar/dissimilar)
2 of 13
Research on Coding: findings
ps tend to do worse with acoustically similar words but if they were asked to recall after 20 minutes (LTM recall) then they did worse recalling semantically similar words
3 of 13
Research on Coding: conclusion
shows that information is coded semantically in the LTM
4 of 13
Research on Coding: Limitation
artificial stimuli- not meaningful material so should generalise with caution
5 of 13
Research on Capacity: digit span
Jacobs- mean span for digits was 9.3 items. mean span for letters was 7.3 items
6 of 13
Research on Capacity: span of memory and chunking
Miller- 7+-2
7 of 13
Research on Capacity: limitation (Jacobs)
Lacking validity- lacks control (old study) may have been confounding variables
8 of 13
Research on Capacity: limitation (Miller)
Not so many chunks- Cowan (2001) reviewed other research and found that there was only about 4 chunks
9 of 13
Research on Duration: STM
Peterson and Peterson- found that STM has a short duration unless we repeat it over again
10 of 13
Research on Duration: LTM
Bahrick- yearbook- 15 years after had 90% accuracy. 48 years after had accuracy of 70%
11 of 13
Research on Duration: limitation (Peterson and Peterson)
meaningless stimuli - doesnt reflect real life- lacks external validity
12 of 13
Research on Duration: strength (Bahrick)
higher external validity- meaningful stimuli- real life memories. But it wasnt controlled so some may have rehearsed more than others
