Coding/Capacity/Duration - AO1 Flashcards
Who conducted research into coding?
Baddely
How is the STM coded?
acoustically
How is the LTM coded?
semantically
What was the procedure of Baddely’s research into coding?
Gave a list of words to 4 groups 7 then had to recall the words in the right order:
1) Acoustically similar
2) Acoustically dissimilar
3) Semantically similar
4) Semantically dissimilar
What did Baddely find in his coding research?
Immediate recall - Ppts did worse with acoustically similar words Delayed recall (20min) - Ppts did worse with semantically similar words
What is the capacity of STM?
7 +/-2
Who conducted research into capacity?
Jacobs and his digit span
Miller and chucking and memory span
How id Jacobs conduct his research into capacity?
Investigator readout 4 digits to the ppts and they had to recall in the right order - if successful the number of digits increased.
Mean span for numbers = 9.3
Mean span for letters = 7.3
What is the capacity of LTM?
Infinite / Unlimited
What is the duration of STM?
18 seconds
Who conducted research into the duration of STM?
Peterson and Peterson
How did Peterson and Peterson conduct their research into duration?
Ppts were given 3 letters to remember and then had to count down from a random 3 digit number they were given until told to stop.
Found the longer they counted down for the less they remembered the letters
