The purpose of this research is to test the temporal stability and validity of decompositional perceptions measures. The test is based upon a perceptions measurement experiment focusing on the perceived visual congruence between product concept statements and product prototypes that were designed by manipulating four product characteristics that affected product appearance. The results indicate the perceptions measures are characterized by considerable temporal stability, discriminant validity, and predictive validity.
