Cognitive measurements for the Repertory Grid Technique: assuring quality in subjective experience explorations

This article analyses the Repertory Grid Technique (RGT) from its original point of view (constructivist psychology) through cognitive measurements for product and user profiling. This is a cascade profiling system that starts exploring the subjective experience (mixed information about physical, functional and emotional elements obtained from the RGT interview) through product preference profiles and then analyzes the user’s cognitive structure through cognitive complexity profiles. It is a procedure that traces implications from a top-down process in order to assure not only the quality of the product, but also the quality of the users’ mental models
