Suppose your dad wants you to buy a car from the car yard that's the 2008 model, worth $10000 (registers in phonological loop)
* info travels to central executive
* info is transferred into LTM through link of episodic buffer
You then go to the car salesman, who tells you about the car (registers in phonological loop)
You examine the interior of the car, and imagine what it would look like if you were sitting in it (visuo-spatial sketchpad)
On instruction from the central executive, episodic buffer retrieves info from LTM tapping into semantic network storage of dad/car/model, to associate with info already in working memory
Central executive is involved in the decision making process as to whether should buy car or not depending on what dad said
Episodic buffer then recommits the modified memory back into LTM
