- - - - 443 female students (aged 8-19) from North London
      - Participants had to repeat a string of numbers/letters in the same order which gradually increased each time. Started with 4 until participants couldn't recall much longer
      - Findings: Students had an average span of 5.3 - 7.3 letters and 7.5 - 9.3 numbers
    - - gave trigrams (3 consonants) to remember and given 3 digit number to count back from to stop them rehearsing the trigram
      - They were asked to stop and recall the trigram at either 3, 6, 9, 12, 15, 18 or 30 seconds (supports STM not being able to go past 30 seconds)
      - findings - 80% recall at 3 seconds, 10% at 18 seconds and 0% at 30 seconds
  - - - 392 Americans - half of them had graduated in the last 15 years and 45 years ago
      - They were asked to recall the peoples names without a photo prompt and then with
      - Findings - people who had graduated in the last 15 years recalled 90% of names when looking at photos and 80% without - people who graduated around 45 years ago recalled 70% of names when looking at photos
  - - - Immediate recall - acostically different had highest recall
      - Delayed recall - semantically dissimilar highest recall
      - tells us the STM must code information acoustically and LTM must code information semantically
- - - - added in 30 minutes later, parts of the theory the theory didn't explain so they added it in later
      - original theory lacked reliability, didnt fully explain how STM worked
  - - - 2 groups - 1 had to do an auditory and visual task at the same time (describe whilst detecting light)
      - other condition - 2 visual tasks to do at the same time
      - found 2 visual tasks they had to prioritise one over the other whereas with auditory and visual they could do both at the same time - helps to explain ability to multitask
