Memory - Mark scheme

Question 1

Capacity of the STM

Answer 1

7 +/- 2 items (Miller)
Can be improved through chuncking
Shown using digit span tests (Jacobs)

Question 2

Duration of STM

Answer 2

18-30 secs
Duration extended through rehersal
Peterson & Peterson - trigrams

Question 3

Describe the encoding of info in STM and LTM

Answer 3

STM: Acoustic encoding
LTM: Semantic encoding
Baddeley(1966) - similar sounding/ meaning words
STM confused acoustically similar words
LTM confused with semantically simillar words

Question 4

Outline and evaluate the multi-store model of memory

Answer 4

Sensory - STM - LTM
Attention transfers info to STM; rehersal transfers to LTM
STM & LTM have differnt capacity/duration/encoding

Supported by Baddeley and Peterson & Peterson
Too simplistic - only one type of STM and LTM
Patient KF condradicts it
