Lecture 5

Question 1

Atikinson and Shiffrin 3 memory structures

Answer 1

• Sensory memory
• Short-term store
• Long-term store

Question 2

How we differentiate the stores

Answer 2

• Encoding
• Duration
• Capacity
• Type of code(s)

Question 3

Short-term store

Answer 3

• Selective attention (select information from sensory memory)
• Retrieve from long term store

Question 4

Short-term store duration

Answer 4

• Roughly 15 seconds
• Present something, delay, remember?
• Present something, delay with activity, remember?

Question 5

Short-term store code

Answer 5

• Coding in terms of sounds
• Acoustic verbal linguistic code
• Intrusion errors are usually acoustic (D instead of T)

Question 6

Sensory memory code

Answer 6

• Basic features
• Not semantic
• Not linguistic

Question 7

Long-term store code

Answer 7

• Coding in terms of semantics

- intrusion errors usually semantic (ship for boat)

Question 8

Short-term store capacity

Answer 8

• Very small

7 +/- 2

Question 9

Reduction encoding

Answer 9

Chunking

Question 10

Elaboration encoding

Answer 10

Adding to input

Question 11

Serial position curve

Answer 11

• List of items
• Recall as many items as possible
• Primacy section: first items in long-term store
• Middle numbers have little transfer in long-term store do to lack of rehearsal
• Recency section: last items still be rehearsed, accessing from short-term store
• Distraction at end prevents rehearsal of last items causing them to be lost
