I've just reserved that book from the library. Several books I've read recently have touched on the techniques supermarkets use to push shoppers into making the choices they want us to make, and it all seems very interesting.

The document I was reading was about secondary school library design, but I expect it was just extrapolating from a study of adult shoppers. Though I suppose even small children could pick up the instinct from years being pushed in buggies or led by the hand in the direction that their parents default to going in.
