social influence - research into coding capacity and duration Flashcards
Who investigated the coding of the STM and LTM
Baddeley
Outline the procedure used to investigate the duration of the STM
He showed the participant a list of words in 4 categories
semantically similar word list (nap, sleep, snooze, doz)
semantically dissimilar (happy, sad, bored)
acoustically similar (bat ,rap ,cat)
acoustically dissimilar (happy, excited, normal)
the participants were asked to recall the list immediately
outline the findings of research into the coding of STM
- Participants made more mistakes on the acoustically similar word list
What were the conclusion of research into the coding of STM
- The STM mainly codes acoustically.
Outline the procedure of the research into the LTM
He showed the participant a list of words in 4 categories
semantically similar word list (nap, sleep, snooze, doz)
semantically dissimilar (happy, sad, bored)
acoustically similar (bat ,rap, cat)
acoustically dissimilar (happy, excited, normal)
The participants were asked to recall the word list 20 minutes after.
Outline the findings of the research into the LTM
participants made more mistakes on the semantically similar word list.
Conclusion of the research into coding of the LTM
the LTM codes mainly semantically.
Who researched the capacity of the STM
Miller
Outline the procedure of Millers research into capacity of long term memory
Participants were shown strings of unrelated digits, that increased digits each time. their digit span task was measured until the participants could no longer recall the digits in the correct sequence.
What are the findings of the research into the capacity of the STM by Miller
- Participants could recall 5-9 items
conclusion
- the stm has a limited capacity of 5 to 9 item
