> Psychogeography is the exploration of urban environments that emphasizes interpersonal connections to places and arbitrary routes, and follows a loosely defined urban practice known as the dérive. It was developed by members of the Letterist International and Situationist International, which were revolutionary groups influenced by Marxist and anarchist theory as well as the attitudes and methods of Dadaists and Surrealists. In 1955, Guy Debord defined psychogeography as "the study of the precise laws and specific effects of the geographical environment, consciously organized or not, on the emotions and behavior of individuals."
> The first published discussion of psychogeography was in the Lettrist journal Potlatch (1954), which included a 'Psychogeographical Game of the Week': Depending on what you are after, choose an area, a more or less populous city, a more or less lively street. Build a house. Furnish it. Make the most of its decoration and surroundings. Choose the season and the time. Gather together the right people, the best records and drinks. Lighting and conversation must, of course, be appropriate, along with the weather and your memories. If your calculations are correct, you should find the outcome satisfying.
