Sometimes it just feels right: The differential weighting of affect-consistent and affect-inconsistent product information

An affect-confirmation process is proposed to explain the conditions in which information that is similar in valence (i.e., evaluatively consistent) with a person's mood is weighted more heavily in product judgments. Specifically, the affect that participants experience as a result of a transitory mood state may appear to either confirm or disconfirm their reactions to product information, leading them to give this information more or less weight when evaluating the product as a whole. This affective confirmation typically occurs when hedonic criteria are considered more important in evaluation than utilitarian criteria. Four experiments confirmed implications of this conceptualization.
