6. Reliability high or low in duration for STM duration research?

  • High as the settings were controlled
  • Low as the settings were controlled
  • Low as the settings were not controleld

7. What were the findings of Jacobs research into STM capacity?

  • STM is encoded acoustically as PPS found it harder to recall letters which were acoustically dissimilar
  • Recall for: numbers=9.3/ letters=7.3.
  • 80% of trigrams were recalled at 3 second intervals. This decreased down to 10% at 18 secs.

8. Was age a factor in research into capacity for STM?

  • Yes.
  • Yes. Eight year olds remembered 6.6 characters, and 19 year olds remembered 8.6.
  • No.

9. How was duration for STM tested?

  • Using Nonsense Trigrams
  • Digit span technique

10. What was validity and generalisability like in study for duration in STM?

  • Ecological validity was low as it was a lab experiment. Generalisability was low as procedure was not everyday behaviour.
  • Ecological validity was high as it was a lab experiment. Generalisability was low as procedure was not everyday behaviour.
  • Ecological validity was high as it was a lab experiment. Generalisability was high as procedure was not everyday behaviour.

11. Who conducted research into Encoding for STM?

  • Conrad
  • Peterson and Peterson
  • Jacobs

12. Duration of STM?

  • Infinate
  • 18 seconds
  • 1minute

13. Who conducted research for STM duration?

  • Jacobs
  • Peterson and Peterson
  • Conrad

14. Findings of duration of STM research?

  • 80% of trigrams were recalled at 3 second intervals. This decreased down to 10% at 18 secs.
  • Recall for: numbers=9.3/ letters=7.3.
  • STM is encoded acoustically as PPS found it harder to recall letters which were acoustically dissimilar
