Multi store Model

Question 1

Capicity

Answer 1

The size of the store

Question 2

Encoding

Answer 2

How memories are stored as memories

Question 3

Retrieval

Answer 3

How we access memories when an output is needed

Question 4

Storage

Answer 4

How memories remain as memories after they have been registered

Question 5

Duration

Answer 5

How long the information remains in the store

Question 6

Mode of Representation

Answer 6

The way in which memory is stored

Question 7

Sensory Store

Answer 7

• information obtained through senses
• lasts up to 2 seconds
• if not paid attention too it can’t be passed on to our short term memory and will be lost through trace decay

Question 8

Short term memory

Answer 8

• sensory information was paid attention too
• DURATION: lasts up to 30 seconds
• CAPACITY: 5-8 items
• auditory (coding)
• if not rehearsed will not pass into long term ad will be lost through trace decay

Question 9

long term memory

Answer 9

• unlimited duration and capacity
• short term information was rehearsed
• semantic information
• retrieval cue used
• CODING; visually and by meaning (semantic)

Question 10

Evidence- Peterson and Peterson (1959)

Answer 10

Aim- to investigate the duration of short term memory and provide empirical evidence for the multi store model
Procedure:
-lab experiment
-24 ppt (psych students)
-had to recall trigrams for 18 seconds
-interference tasks to prevent rehearsal
-Correct recall was unlikely after 15-18 seconds (10% remembered after 18 seconds)
-suggesting decay in short term memory occurs after a period of 15 seconds

Question 11

Strengths

Answer 11

Supporting evidence, increases reliability and scientific credability.
Studies are replicable
Supported by evidence from brain damage cases as they show a distinction between LTM and STM e.g. HM
