Consumer learning involves acquiring knowledge about purchasing and consuming products through experience. There are two main types of learning: intentional learning through deliberate research, and incidental learning acquired accidentally. Marketers must educate consumers on where to buy products, how to use them, maintain them, and dispose of them. Learning theories include behavioral theories based on stimulus-response and cognitive theories involving mental processing. Behavioral theories include classical conditioning of pairing stimuli, instrumental conditioning of rewarding behaviors, and observational learning from others. Cognitive learning involves problem-solving, observation, rote memorization, and reasoning.
