In many situations, people make judgments on the basis of incomplete information, inferring unavailable attributes from available ones. These inference processes may also well operate when judgments about a product’s user-experience are made. To examine this, an inference model of user-experience, based on Hassenzahl and Monk’s , was explored in three studies using Web sites. All studies supported the model’s predictions and its stability, with hands-on experience, different products, and different usage modes (action mode versus goal mode). Within a unified framework of judgment as inference [Kruglanski et al. 2007], our approach allows for the integration of the effects of a wide range of information sources on judgments of user-experience.
