Presents a perspective for product, store, and customer-service performance management that is based on an integration of adaptation-level theory and dynamic opponent-process theory. This perspective is discussed in terms of the concepts of expectations, fulfillment of expectations (disconfirmation), and satisfaction/dissatisfaction. Satisfaction with a product is described as the summary psychological state resulting when the emotion surrounding disconfirmed expectations is coupled with the consumer's prior feelings about the consumption experience. Each concept is positioned in a satisfaction framework and operationalized for empirical testing and practical application. (70 ref) (PsycINFO Database Record (c) 2012 APA, all rights reserved)
