Researchers describe their research into design at the Royal Melbourne Institute of Technology. One kind of research illuminates the ways in which designers marshal their intelligence, especially their spatial intelligence, to construct the mental space within which they practice design. The other reveals how public behaviors are invented and used to support design practice. Introductory chapters cover the evolution of the invitational program in design practice research; and thinking about architecture, thinking about architects.
