Question 1

Answer 1

. STM was made of multiple stores not just one
.Two tasks both verbal or both visual perform less well than if you do them separately
.Do two things verbal and visual no interference do them just as well

Question 1

Who created the WMM?

Answer 1

Baddeley and Hitch (1974)

Question 2

What are the components of the WMM?

Answer 2

.Central executive
.Phonological loop
.Visuo-spatial sketchpad
.Episodic buffer

Question 3

What is the role and encoding/capacity of the central executive?

Answer 3

Role- monitor incoming data divide attention to tasks allocate different slave systems
Encoding- senses
Capacity- very limited

Question 4

What is the role and encoding/capacity of the phonological loop?

Answer 4

Role- auditory info preserves order
.phonological store- words you hear
.articulatory process- allows rehearsal
Encoding- acoustic
Capacity- limited

Question 5

What is the role and encoding/capacity of the Visuo-spatial sketchpad?

Answer 5

Role- stores visual/spatial info used plan a spatial task
.visual cache stores visual data
.inner scribe records arrangement of objects in visual field
Encoding- visual/spatial
Capacity- 3/4 objects

Question 6

What is the role and encoding/capacity of the episodic buffer?

Answer 6

Role- temporary store for info takes all info from other stores that maintains time sequencing recording events (episodes)
Capacity- limited 4 chunks
