A shown in the diagram the information processing consists of exposure, attention, comprehension and retention of the marketing and non-marketing stimuli. For successful sales, the consumer must be properly and repeatedly exposed to the message. His attention should be drawn, such that he understands what is to be conveyed and retains it in his mind.

  1. Stores information and past experience about the product, which serves as a standard for comparing other products and brands.
  2. Evaluative criteria which could be different for different individuals.
  3. Attitudes or the state of mind which changes from time to time, and helps in choosing the product.
  4. The personality of the consumer which guides him to make a choice suiting his personality.

Decision process
This chapter is dealt with later in the text, and consists basically of problem recognition, internal and external search, evaluation and the purchase. The decision outcome or the satisfaction and dissatisfaction is also an important factor which influences further decisions. The decision process may involve extensive problem solving, limited problem solving or routinised response behavior. This depends on the type and value of the product to be purchased.
