Psychogeography is the study of how geography and the built environment influence human emotions and behavior. It began in the 1950s with the Situationist International group in France who saw it as a way to critique modern capitalist cities. Some key practices of psychogeography include the derive, where one explores an area by drifting aimlessly and observing how the environment shapes their movements and perceptions. In recent years there has been a resurgence of interest in psychogeography through community mapping projects, guided walks, and sharing experiences of places online.
