The association between designers and social scientists in environmental psychology burst into the public arena at the end of the 1960's with conferences on Architectural Psychology in Scotland, Environmental Design Research in the USA, and the publication of the journal Environment and Behaviour. In the seventeen or so years since this introduction, theoretical advances combined with statistical developments have improved our ability to assess perception of environments. This paper reports the recent reanalysis of a study carried out in 1970 to measure cross cultural differences in attitudes to the external appearance of house forms. The reanalysis, using a hierarchy of individual differences models, showed that the cross-cultural differences were not as great as originally thought.
