Abstract

A substantial proportion of user modeling research deals with detection, classification and use of as well as adaptation to the users' preferences. In this paper, we develop a questionnaire to assess aspects of perceptual preferences in regard to information processing, knowledge gain and learning, named Perceptual Preferences Questionnaire (PPQ). The PPQ is validated based on the results of an online survey with forum users (n=76). Given the perceptual preferences of a user, we explore first implications on how to present information to that specific user in order to ease understanding, which can be achieved by matching his/her perceptual preferences. Further research aims to combine the PPQ with implicit testing based on the users' textual utterances and the users' interests.
