The accuracy of brand and attribute judgments: The role of information relevancy, product experience, and attribute-relationship schemata

A multidimensional approach for accuracy of ratings is introduced that examines consumers' abilities to assess various brands across a set of attributes and attribute performances across a set of brands. A model is presented that addresses the roles of the relevancy of information, attribute-relationship schemata, and consumers' product category experience on the accuracy of their brand attribute ratings. Study participants were provided either with relevant or irrelevant attribute information for various automobile brands and Eater asked to rate the attribute performances of brands. The results indicate that the provision of relevant information in the judgment environment increases brand and attribute rating accuracy but does not favorably affect consumers' brand attribute-relationship schemata. Rather consumers' product experience was directly related to their attribute-relationship schemata, which in turn were related to improved accuracy of brand and attribute ratings.
