- capacity of short term memory - Jacobs
- method
- jacobs tested the capacity for digits and letters in stm
- used immediate digit span task
- participants read lists then immediatey recited them back
- the length of the sequence gradually increased
- findings
- 7.3 letters remembered
- 9.3 numbers remembered
- jacobs suggested that more numbers could be remembered because there are only 10 numbers, but 26 letters
- limitations
- can not explain indivudal differences in stm
- the amount remembered can be affected by age
- 8 year olds could only remember 6.6 digits, 19 year olds could remember 8.6 digits
- as we age there may be changes in brain capacity or we could develop strategies to improve it
- this suggests the capacity of stm is not fixed, and that individual differences could have an affect
- method
