The Howard-Sheth Model of Consumer Behavior highlights three types of buying categories and four general factors that impact the consumer decision process. The Bettman's Model of Information Processing emphasizes the consumer as an active monitor and includes scanner and interrupt mechanisms. The HCB Model of Consumer Behavior shows the consumer decision process is influenced by both internal and external situational factors.
