Abstract
Geometric representations of psychological dimensions were analyzed and compared to an alternative set-theoretical approach. Judgments of similarity between forms and figures by 244 high school and undergraduate students revealed the following effects: (a) Qualitative attributes were curved relative to quantitative attributes, contrary to intradimensional subtractivity; (b) quantitative attributes augmented differences in qualitative attributes, contrary to interdimensional additivity; and (c) adding a new dimension with a fixed value increased similarity, contrary to translation invariance. The implications of these results for multidimensional representations of proximity data are discussed. (24 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved).
