Q

Why was the WMM proposed?

A
  • Baddeley realised memory was more complicated than the MSM made it out to be.
  • Baddeley proposed WMM as something that carries out functions of STM and some of the work of LTM too

Q

What is the visuo-spatial sketchpad?

A
  • It allows us to recreated images either based on something we are seeing in real time or we have seen in pass.

Q

What is the visuo-spatial sketchpad?

A
  • It is a unitary store processing visual and spatial material together or whether these operations are carried out by separate stores
  • Stores visual information
  • 3/4 object capacity

Q

What is central executive?

A
  • It is the control center responsible for coordinating the other slave units
  • It is able to process information from any of the senses and appears to have minimal storage capacity
  • involved in problem solving and decision making

Q

What is the phonological loop?

A
  • Deals with auditory information, especially for recall of words in the right order
  • holds sounds for a few moments (2 second capacity), storing the sounds

Q

Why was the Episodic Buffer added?

A
  • The central executive has no storage of its own and the other two stores hold either visual or auditory information
  • Baddeley realised that there needed to be a store that could hold and coordinate information from all three other stores as well from LTM
17
Q

where is the phonological loop located?

A
  • Temporal Lobe
18
Q

where is the visuo-spatial scratch pad located?

A
  • in the right hemisphere
  • simple tasks in occipital lobe
  • complicated tasks in the parietal lobe
19
Q

where is Episodic buffer located?

A
  • hippocampus
20
Q

where is the central Executive located?

A
  • Frontal lobes
