The Role of Attribute Order and Number Effects in Consumers’ Multiattribute Preferential Decisions

Abstract

The cognitive composition process of attribute information plays a critical role in heuristic aspects of consumers’ multiattribute preferential decisions. This study examines the effects of attribute information order and attribute information amount on consumers’ multiattribute preferential decisions under the premise of consumers’ limited information processing capacity. An experiment with two separate designs is conducted for testing the different hypotheses. The results support the hypothesis that consumers’ multiattribute preferential decisions are influenced by the amount of attribute information received/processed. The attribute information order is found to affect not only the outcomes of consumer decisions but also the amount of attribute information processed. These findings further suggest that consumers may be more inclined to adopt strategies of a noncompensatory heuristic nature when making multiattribute preferential decisions.
