Coding Capacity Duration

Question 1

Coding STM LTM ao1

Answer 1

BADDELEY
-investigate how code info
-showed ppt lists of words in 4 categories
1 acoustically similar
2 acoustically dissimilar
3 semantically similar
4 semantically dissimilar
- immediately after(20mint) each presentation recall lists in correct order
STM= more mistakes acoustically similar
STM= codes acoustically
LTM= more mistakes on semantically similar
LTM= codes semantically

Question 2

Capacity AO1 stm

Answer 2

MILLER
-used digit span tech
-given strings of unrelated digits that inc by one digit every time measured until no longer could recall in correct sequence
-ppt recall 5-9 items more if chunked
-limited 5-9 can be inc by putting in meaningful chunk

Question 3

Duration ao1 stm

Answer 3

PETERSON
-24 undergrad Students
-ppt presented with consonant Trigram to remember
-3 digit number nd asked to count back to prevent rehearsal
-stopped at diff intervals nd asked to recall consonant trigram
-findings= 3 sec 80% recalled 18sec 10%
-stm lasts 18-30 sec unless rehearsal

Question 4

duration LTM

Answer 4

BAHRICK
- tested 392 American hs grad 17-74 in memory of classmates
-condition 1 recall names using photo
-condition 2 recall name no photo
- condition 1= 70% recalled accurate after 48y with photo
-condition 2= 30% ppt recalled accurately after 48y no photo
-can potentially last life time with correct cues

Question 5

AO3 limitation for all

Answer 5

-lacks mundane realism
-task artificial
-therefore diff to gen findings to real life of the as does not reflect most real life memory
- lowering external val

Question 6

Answer 6

P-high reliability
E-controlled env
E-therefore repeated same cond
L-to check for consistency

Question 7

Strength

Answer 7

P- high control over ev
E-carried out in a controlled setting e.g
E-means we are more likely to establish cause and effect between IV
L- inc internal val
