- Capacity of STM
- Miller (1956)
- Grouping the items into chunks of 3 is helpful, especially when this combination means something to the participant
- Evaluation
- Didn't specify how large each ‘chunk’ of information could be and therefore we are unable to conclude the exact capacity of short-term memory.
- Didn't take into account other factors that could affect short term memory like age
- Findings
- Jacobs (1887)
- Used the digit span technique to assess STM capacity
- Evaluation
- Used 443 female students from ages 8-19 in the North London Collegiate School -not representative
- Participants had to repeat back a string of numbers or letters in the same order and the number of digits/letters was gradually increased, until the participants could no longer recall the sequence
- Findings
- Found that short term memory improved with age
- Letter average - 7.3
- Miller (1956)
