This book focuses on externalist approaches to art. It is the first fruit of a workshop held in Milan in September 2009, where leading scholars in the emerging field of psychology of art compared their different approaches using a neutral language and discussing freely their goals.The event threw up common grounds for future research activities. First, there is a considerable interest in using cognitive and neural inspired techniques to help art historians, museum curators, art archiving, art preservation. Secondly, cognitive scientists and neuroscientists are rather open to using art as a special way of accessing the structures of the mind. Third, there are artists who explicitly draw inspiration out of current research on various aspects of the mind. Fourth, during the workshop, a converging methodological paradigm emerged around which more specific efforts could be encouraged.
