5- Memory System

Question 1

What model was proposed in 1968?

Answer 1

The Atkinson-Shiffrin model

Question 2

3 parts of the Atkinson-Shiffrin model

Answer 2

Sensory store, short term store, long term store

Question 3

How is the sensory store coded?

Answer 3

Modality specific

Question 4

What is the duration of the sensory store?

Answer 4

Short

Question 5

What is the capacity of the short term store?

Answer 5

Limited

Question 6

How is the short term store characterised?

Answer 6

We pay attention to information and can therefore remember this

Question 7

What is the duration and capacity of the long term store?

Answer 7

Almost limitless

Question 8

Can we always access the information in the long term store?

Answer 8

No

Question 9

How do we retrieve information from the long term store?

Answer 9

Indirectly by first becoming available in STM

Question 10

How does information go into the sensory memory?

Answer 10

Environmental stimuli

Question 11

What information is lost from sensory memory?

Answer 11

Information that isn’t encoded

Question 12

How is information transferred from sensory memory to STM?

Answer 12

Selective attention

Question 13

What information is lost from STM?

Answer 13

Information that isn’t encoded

Question 14

How is information transferred from STM to LTM?

Answer 14

Storage

Question 15

How is information transferred from LTM to STM?

Answer 15

Retrieval

Question 16

How is information maintained in STM?

Answer 16

Rehearsal

Question 17

Why is information lost in LTM?

Answer 17

Due to retrieval failure, interference, decay

Question 18

What is the main model of STM?

Answer 18

Baddeley’s Model (1974, 2000)

Question 19

What are the 4 components of Baddeley’s model?

Answer 19

Central executive, episodic buffer, phonological loop, visuospatial sketchpad

Question 20

What is the role of the episodic buffer?

Answer 20

Manipulates all different incoming info and gives a sense of time

Question 21

What info does the phonological loop deal with?

Answer 21

Auditory/verbal

Question 22

What info does the visuospatial sketchpad deal with?

Answer 22

Visual/spatial info

Question 23

What is the role of the central executive?

Answer 23

Integrating all material

Question 24

2 brain areas involved in declarative memory

Answer 24

Medial temporal lobe, diencephalon

Question 25

Is declarative memory explicit or implicit?

Answer 25

Explicit

Question 26

Is nondeclarative memory explicit or implicit?

Answer 26

Implicit

Question 27

2 types of nondeclarative memory

Answer 27

Procedural memory and classical conditioning

Question 28

Brain area associated with procedural memory

Answer 28

Striatum

Question 29

2 types of classical conditioning

Answer 29

Skeletal musculature and emotional responses

Question 30

Brain area involved in skeletal musculature

Answer 30

Cerebellum

Question 31

What memories does skeletal musculature deal with?

Answer 31

Movement memories we don’t want to consciously think about

Question 32

Brain area involved in emotional responses

Answer 32

Amygdala

Question 33

How is emotion associated with memory?

Answer 33

Emotional experience will trigger a memory

Question 34

How is memory supported?

Answer 34

By distinct systems

Question 35

What is encoding?

Answer 35

Moving info via sensory memory to STM to LTM

Question 36

What does encoding require?

Answer 36

Mental effort
