16
Q

How is information maintained in STM?

17
Q

Why is information lost in LTM?

A

Due to retrieval failure, interference, decay

18
Q

What is the main model of STM?

A

Baddeley’s Model (1974, 2000)

19
Q

What are the 4 components of Baddeley’s model?

A

Central executive, episodic buffer, phonological loop, visuospatial sketchpad

20
Q

What is the role of the episodic buffer?

A

Manipulates all different incoming info and gives a sense of time

21
Q

What info does the phonological loop deal with?

A

Auditory/verbal

22
Q

What info does the visuospatial sketchpad deal with?

A

Visual/spatial info

23
Q

What is the role of the central executive?

A

Integrating all material

24
Q

2 brain areas involved in declarative memory

A

Medial temporal lobe, diencephalon

25
Is declarative memory explicit or implicit?
Explicit
26
Is nondeclarative memory explicit or implicit?
Implicit
27
2 types of nondeclarative memory
Procedural memory and classical conditioning
28
Brain area associated with procedural memory
Striatum
29
2 types of classical conditioning
Skeletal musculature and emotional responses
30
Brain area involved in skeletal musculature
Cerebellum
31
What memories does skeletal musculature deal with?
Movement memories we don't want to consciously think about
32
Brain area involved in emotional responses
Amygdala
33
How is emotion associated with memory?
Emotional experience will trigger a memory
34
How is memory supported?
By distinct systems
35
What is encoding?
Moving info via sensory memory to STM to LTM
36
What does encoding require?
Mental effort
