ATTITUDES AND SOCIAL COGNITION How Choice Affects and Reflects Preferences: Revisiting the Free-Choice Paradigm

After making a choice between 2 objects, people reevaluate their chosen item more positively and their rejected item more negatively (i.e., they spread the alternatives). Since Brehm’s (1956) initial free-choice experiment, psychologists have interpreted the spreading of alternatives as evidence for choice-induced attitude change. It is widely assumed to occur because choosing creates cognitive...

Learning Preferences and User Engagement Using Choice and Time Data

Choice decisions made by users of online applications can suffer from biases due to the users’ level of engagement. For instance, low engagement users may make random choices with no concern for the quality of items offered. This biased choice data can corrupt estimates of user preferences for items. However, one can correct for these biases if additional behavioral data is utilized. To do this...

Connecting cognition and consumer choice.

We describe what can be gained from connecting cognition and consumer choice by discussing two contexts ripe for interaction between the two fields. The first-context effects on choice-has already been addressed by cognitive science yielding insights about cognitive process but there is promise for more interaction. The second is learning and representation in choice where relevant theories in ...

Prioritized Preferences and Choice Constraints

It is increasingly recognised that user preferences should be addressed in many advanced database applications, such as adaptive searching in databases. However, the fundamental issue of how preferences impact the semantics and rankings in a relation is not resolved. In this paper, we model a user preference term involving one attribute as a hierarchy of its underlying data values and formalise...
