This document discusses consumer attitude formation and change. It covers four key concepts: 1) Attitudes are learned predispositions towards objects; 2) Attitudes have consistency; 3) Attitudes occur within situations; 4) Attitudes must have a clearly defined object. The document then examines structural models of attitudes, including the tricomponent model of cognition, affect, and conation; multiattribute models looking at attributes/beliefs that form overall attitudes; and models addressing trying to consume and attitudes towards ads. Diagrams depict relationships between components in various models.
