Memory

Question 1

Who created the MSM?

Answer 1

Atkinson and Shiffrin
(1968)

Question 2

What are the 3 MSM stores

Answer 2

Sensory register
STM
LTM

Question 3

Describe CODING

Answer 3

different information types the brain uses to store memory

Question 4

Describe CAPACITY

Answer 4

how much info can be held by a store

Question 5

Describe DURATION

Answer 5

how long information can be held in that store for before loss

Question 6

What happens in the sensory register

Answer 6

1. 5 main senses detected by sensory neuron and received by brain
   2.sensory info from senses is recorded automatically, info passed on to STM by paying ATTENTION
2. STM passes info to LTM through REHEARSAL- maintenance rehearsal or elaborative rehearsal
3. Info is passed back from LTM with RETRIEVAL, and info can be lost via DISPLACEMENT(new info).

Question 7

Describe the sensory register

Answer 7

• not under COGNITIVE CONTROL like STM or LTM
  -all info found in stm/ ltm were initially gathered by sensory reg

Question 8

Sensory register (coding, cap, duration)

Answer 8

CODING-modality specific
CAPACITY- very large, unlimited?- contains all sense impressions for all senses in the moment, only what is paid attention to is passed to STM
DURATION- very low, low as 250 milliseconds( so much info held, cant be retained for long)

Question 9

How can the capacity of STM be improved?

Answer 9

by CHUNKING info= reduces number of items overall

Question 10

Difference between maintenance rehearsal and elaborative rehearsal

Answer 10

Maintenance- repeating the information

Elaborative- linking to information already in LTM
