This document discusses consumer dynamics and factors that influence changes in consumer attitudes. It defines consumer dynamics as the study of forces that determine consumer responses to their economic, social, and cultural environments. Consumer attitudes are learned and influence their behavior, but can change based on internal factors like needs and external factors like their environment. Marketers aim to change consumer attitudes by altering the motivational functions of products, associating products with influential groups or events, addressing conflicting attitudes, modifying brand components, and challenging beliefs about competitors' brands. Changes in a consumer's inherent traits, environment, knowledge, and motivation can all impact their attitudes.
