This research investigates preference uncertainty generated as a function of specific alternative characteristics during multiattribute evaluative judgments. We propose that preference uncertainty has at least two behavioral manifestations: longer judgment times and greater response error in...

This paper extends the behavioral results reported in Fischer et al. (2000) by developing a model addressing preference uncertainty in multiattribute evaluation. The model is motivated by two hypotheses regarding properties of multiattribute profiles that lead to greater preference uncertainty....

This study argues the need for, and then develops, some graph theoretic approaches for comparing complex information processing models of individual decisions. Two similarity coefficients are proposed, and a coefficient based on path and reachability structure is shown to be preferable. Some...
