Very interesting book about the psychology of Interaction Design. Anderson does a very good job in adapting the Maslow pyramid of needs to a pyramid of the needs of the interaction design and user experience. The rest of the book fails in building a consistent framework to support this pyramid, mostly serving recipes after recipes for the design of interaction taking into account human cognition. The book serves as an interesting introduction to the topic, but stays at the surface, even if for a 2011 book it was surprising conscious about the pitfalls of gamification and other domains.
