Memory

Question 1

Coding Baddeley
Procedure and findings

Answer 1

P-Acoustically similar(cat,cab,can) words or dissimilar
Semantically similar(great,large,big) or dissimilar words
F-Immediate recall worse with acoustically similar words(STM)
Recall after 20mins worse with semantically similar words(LTM)

Question 2

Capacity-Digit SPan- Jacobs P and F

Answer 2

P-Researcher reads 4 digits and increases until the ppt cannot recall the order correctly. Final number=digit span
F-On average ppt could repeat back 9.3 numbers and 7.3 letters in the correct order immediately after they were presented

Question 3

Capacity Miller-Magic number

P+F

Answer 3

P-Miller observed everyday practice, noted that things came in 7s(days of week,deadly sins)
F-The span of the STM is 7+/-2 but is increased by chunking(grouping sets of digits/letters into meaningful units.

Question 4

Duration STM
Peterson and Peterson
Consonant syllables
P+F

Answer 4

P-24 Students were given a consonant syllable(e.g. YCG)
to recall and a 3-digit number to count backwards from
-The retention interval was varied:3-18 seconds
F-After 3 seconds average recall was about 80%
-After 18 seconds about 3%
STM without rehearsal is up to 18seconds

Question 5

Duration LTM
Bahrick yearbook photos

Answer 5

P-Ppt were 362 Americans aged between 17 and 74
1-Recognition test-50 photos from their high school yearbook
2-Free recall test-ppts listed names of their graduating class
F-RT was 90% accurate after 15 years,70% after 48years
FRT-60% recall after 15 years,30% after 48 years

Question 6

Sensory register

Answer 6

All stimuli from the environment pass into the SR
Coding-Modality specific(iconic or echoic)
Capacity-Unlimited
Duration-Very brief

Question 7

STM

Answer 7

STM receives info from SR by paying attention(or from LTM via retrieval)
