Ann Sussman, RA, is an architect, author and researcher. Her books, including Cognitive Architecture and Urban Experience + Design, reveal the unconscious tendencies at work when we navigate the world around us. These ‘hidden’ predispositions reflect our long evolutionary trip per recent research in psychology and neuroscience, and can help explain why we favour certain urban conditions and building configurations and shun others. Understanding ourselves better, Sussman believes, can lead us to build more humanely and ultimately, more successfully for people.
