In order to perform structural analysis of environmental perception and cognition, multidimensional scaling based on similarity and preference ratings were compared to the semantic differential tech-nique in a study employing perspective drawings of urban and sub-urban views sampled from a medium sized Swedish city. The results, obtained for a total of 40 university students, were in fairly close agreement when subjected to metric and nonmetric types of dimensio-nal and cluster analyses. However, concerning the interpretation of the results, the semantic differential technique and preference ratings suggested a dimensional interpretation (two dimensions lab-elled aesthetic/general evaluation and social status evaluation), whereas the multidimensional scaling based on similarity data was more adequately described by a categorical model, type of area and style being distinguishing features attended to. The study, though considered to be tentative and in need of elaboration, clearly de-monstrates the value of multidimensional scaling methods as an al-ternative to the semantic differential technique for structural ana-lysis within the area under consideration.
