Are there any books about the psychology of cartography?
Mark Monmonier's "How to Lie with Maps" may also have some good information. It isn't directed at psychology directly but may have some applicable information - especially regarding the role of map symbology in perception.
There are number of them – in fact, it's an enormous number of them.
- A good starting point is Alan MacEachren's "How Maps Work: Representation, Visualization, and Design". http://www.amazon.com/How-Maps-Work-Representation-Visualization/dp/157230040X
- Not unrelatedly: http://www.cognitivegiscience.psu.edu/publications.html
- You may also find Bertin's classic book, "Semiology of Graphics: Diagrams, Networks, Maps" useful: http://www.amazon.com/Semiology-Graphics-Diagrams-Networks-Maps/dp/1589482611
A good introduction is this cited paper
"Cognition in Cartography"
A cognitive spatial representation (or image) depends upon more than visual input it is an integrated, multimodal representation.

Cognition is an import factor in the psychology of cartography - background knowledge of the viewer/user influences their decision and interpretation of the map they are visualizing.
