Chapter 2 Memory - MSM

Question 1

MSM - Sensory register?

Answer 1

• Sense-specific coding. Very brief duration (Sperling’s study, less than 50ms). High capacity.
• Transfer to STM by attention.

Question 2

MSM - STM?

Answer 2

• Mainly acoustic coding. Limited duration (18s) & capacity (5-9).
• Transfer to LTM by prolonged rehearsal.

Question 3

MSM - LTM?

Answer 3

• Mainly semantic coding. Unlimited duration & capacity.
• Created through prolonged maintenance rehearsal.
• Retrieval from LTM via STM.

Question 4

MSM Evaluations? SLLX

Answer 4

S - Research support
L - More than one STM store
L - Elaborative rehearsal
X - Bygone model

Question 5

MSM Evaluation - Research support? S

Answer 5

• Research shows STM & LTM use different coding & have different capacity.
• CP is that the studies do not use everyday materials (e.g. consonant syllables have no meaning in everyday life), low validity.

Question 6

MSM Evaluation - More than one STM store? L

Answer 6

Studies of amnesia (e.g. KF) show different STM stores for visual & auditory material.

Question 7

MSM Evaluation - Elaborative rehearsal? L

Answer 7

Transfer to LTM more about elaboration (meaningful processing) than prolonged maintenance rehearsal (Craik & Watkins).

Question 8

MSM Evaluation - Bygone model? X

Answer 8

Supporting evidence but also evidence of more than one type of STM & LTM.
