Abstract
Unidimensional and multidimensional scaling of creative designs. We know the sealar values (Method of Successive Intervals) of 41 creative designs, resulting from Inventive Thought tasks using 8 defined criteria related to creativity. The factorial results using these criteria reveal two fundamental evaluative dimensions: one related to the originality of the creative designs and another regarding their efficiency. We want to verify whether these two dimensions, obtained from evaluative criteria defined a priori, turn out to be relevant in describing the evaluative criteria which are followed when one does not provide the estimators (judges) with previously established creativity criteria. The dissimilarities obtained using a data collection task, involving a grouping procedure of the design sets, constitute the input data for a two-way multidimensional scaling metric (ALSCAL Procedure). The coordinates of the designs in the tridimensional solution were used as criteria for different multiple regression analyses. At all times, the factorial scores for the designs on the two aforesaid factors are taken as predictors, provided by the judgments made using definite criteria. The obtained fit allows us to conclude that first two scaling dimensions are related to the previously mentioned two factors.
