Multi-Store Memory

Question 1

Encoding

Answer 1

The form in which the memory is retained

Question 2

Duration

Answer 2

How long it can be stored for

Question 3

Capacity

Answer 3

The amount which can be stored

Question 4

What are the three stores in the right orde

Answer 4

• Sensory Store (SM)
• Short Term Store (STM)
• Long Term Store (LTM)

Question 5

How do we get info into the Sensory Memory?

Answer 5

The SM takes info from the sense organs (that have been been picked up by environmental stimuli)

Question 6

How do we get info into from Sensory Memory to Short Term Memory?

Answer 6

By paying attention to it

Question 7

How do we get info into from Short Term Memory to Long Term Memory?

Answer 7

Rehearsing it

• Maintenance rehearsal keeps it in our STM
• Elaborative rehearsal can get it in our LTM

Question 8

What is the Encoding, Capacity, Duration of Sensory Memory

Answer 8

• Via all senses
• Up to 10 items
• Less then 2s

Question 9

What is the Encoding, Capacity, Duration of Short Term Memory

Answer 9

• Acoustic
• 5-9 items (miller)
• 30s (Peterson & Peterson)

Question 10

What is the Encoding, Capacity, Duration of Long Term Memory

Answer 10

• Semantic
• Unlimited
• Unlimited

Question 11

What causes forgetting at STM & LTM?

Answer 11

Lack of rehearsal/ distractions during rehearsal/ will decay over time if not contiously rehearsed

Question 12

Supporting evidence

Answer 12

Glanzer & Cunitz (1966) found words at the beginning and words at the end of the list were remembered best by participants. Shows how there are two separate stores, primacy effect is that the first words are rehearsed and therefore transferred to STM whereas the last are still in the STM (regency effect) as they’ve just been seen.

MRI scans show which parts of the brain are being used when certain tasks are being carried out; when remembering new info the hippocampus is active, this task requires your LTM. When making a decision the prefrontal lobes are active- this uses your STM
