This book examines two broad perspectives on consumer behavior, that which emphasizes its inner causes such as attitudes and intentions, and that which emphasizes the situational influences that shape it. While marketing and consumer research have well-developed theories that derive from the first, social cognitive, approach, there is little theory-development that relates choice to its environmental causes. The revised and updated edition differs from the first edition by integrating the question of attitude-behavior consistency with the two perspectives on consumer choice.
