Abstract

In this paper we discuss the use of eye tracking technology to explore how individuals process information in a stated preference experiment. With the aim to add some evidences to a very short literature, we dig deeper into the analysis of the visual attention measures to discuss the heterogeneity of the visual process across participants, the attendance of attributes, the visual attention paid and potential trade-offs revealed by the consecutive fixations of pairs of attributes. Our results reinforce the evidence of significant heterogeneity in the individual's visual process, and suggest that the analysis of the sequence of the information fixated can help understanding the decision process.
