L2 - Coding, Capacity, Duration

Question 1

Describe sensory register coding

Answer 1

Modally specific so is different for each sense

Question 2

Describe coding for STM

Answer 2

4 lists 
A - sound similar 
B - sound dissimilar
C - mean similar 
D - mean dissimilar 
No difference between C and D but A was worse than B

Question 3

How is STM coded?

Answer 3

Acoustically

Question 4

Experimental procedure for LTM coding

Answer 4

Participants memorised lists then recalled after 20 mins
C was worse than D
A/B no difference

Question 5

How is LTM coded?

Answer 5

Semantically

Question 6

Sensory register capacity?

Answer 6

Unlimited

Question 7

STM capacity experiment?

Answer 7

Digit span test
Said a sequence which had to be repeated back in same order
Got longer by one digit each time

Question 8

STM capacity?

Answer 8

7 +/-2

Can use chunking

Question 9

250 milliseconds

Question 11

STM duration experiment?

Answer 11

Nonsense trigrams
Given 3 random consonants
Count back from 100 in 3s to prevent maintenance rehearsal

Question 12

Results from nonsense trigrams?

Answer 12

3 sec - 90% accurate
9 sec - 20%
18 - 2%
