Abstract
The Creative Product Semantic Scale (CPSS) is based on a theoretical model which conceptualizes three dimensions of product attributes: Novelty, Resolution, and Elaboration and Synthesis. The revision of the CPSS is described in the present article. Study 1 confirmed that the instrument could detect differences in the level of Novelty of three commercially available household products varying in unusualness. Study 2 was designed to validate the three dimensions of product attributes by testing whether or not the rankings of experts would agree with those of lay judges. Results indicated that judgments of Novelty made by naive judges were consistent with those of experts. The validity of Novelty, and to a lesser degree, that of Elaboration and Synthesis, were verified by Study 2. The validity of Resolution is yet to be established (no significant differences among products were observed). In both studies, Novelty and Resolution were independent, but Elaboration and Synthesis subscales migrated between loading with Novelty and Resolution.
