  4. 4. How will I know if I am learning? By the end of the lesson… E Will be able to describe studies into STM & LTM. C Will be able to explain the findings of research into STM & LTM. A Will be able to evaluate research into STM & LTM.
  5. 5. Memory Test Share on your table: How did you learn the objects? Did you use any strategies?
  6. 6. http://www.youtube.com/wat
  7. 7. Think back to the memory test… What can you remember now? Why do you think you can remember some items better than others? How long can these memories last for?
  8. 8. long (in time) a memory lasts before it is no y of on a longer accessible. a w ati : rsal ininform  STM and LTM differ g duration. hea  How Re sferrin Short an memories last for a very shorter of time, tr term LTM. ov periodTherefore unless they are rehearsed or paidiattention to. g t y to i limited in duration. atin think of STM like an STM isn e You can r b we need to notepad where weep r scribble down things in o . ay e aga ! remember forb shortrwhile.

  10. 10. WRT 303 Can you remember the nonsense Syllable? Count backwards in 3’s….
  11. 11.  Participants were presented with a 3 letter consonant nonsense syllable followed by a 3 digit number.  Nonsense syllables were not memorable such as ‘BBC’.  Participants were then asked to count backwards in 3’s or 4’s to prevent them from rehearsing the nonsense syllable.  Each participant was given to practice trials followed by 8 real trials. On each trial the time spent counting backwards was different (3, 6, 9, 12, 15, 18 seconds).
  12. 12. Results Participants remembered 90% when there was a 3 second interval, but only 2% when there was an 18 second interval. What do these results suggest about the duration of STM?
  13. 13. Results After 18secs, fewer than 10% recalled correctly. After only 3secs, 80% recalled correctly. Recall got progressively worse as the delay grew longer!
  14. 14. Try to evaluate Peterson and Peterson’s study. Think about the strengths and weaknesses and the methods they used. Fill out your ideas in the table. Those aiming for an A-B grade try to do this on your own by generating your own ideas. If you get stuck, you may use page 21 to help you! A02  + A02  -
  15. 15. A02  + A02  - • Showed that forgetting in STM • Did participants just rely on can occur if information is not their STM? They knew they rehearsed. were going to have to recall the items after an interval. • Marsh et al (1997) when participants aren’t expected to be tested, forgetting will occur after just 2 seconds. • Nairne et al (1996) found that items could be recalled after 96 seconds. • Is the study really testing for duration? Or just interference, displacement & forgetting?
  16. 16. Choose one of the 7 key learning questions to answer. Write an answer to your chosen question on a post it note and stick it next to the question. Your answer must be more than 10 words but less that 30!
