What is a perceptual region

A perceptual region is one created in the mind of the viewer according to associated feelings and ideas

Explanation:

A perceptual region exists where there are common assumptions about a place and its people. For example, to say, "this town is backwards and has no opportunity" indicates a perceptual region. Another person with a different point of view could see the same place in an entirely different way; for example, rather than a dead end, a place where life is quiet and without stress.
