How does a discrepancy between the ideal state and the actual state affect consumer behavior?

The ideal state is what the consumer wishes to have whereas the actual state is what the consumer has in reality. The discrepancy between the two states is known as problem recognition and it affects consumer behavior. Whenever the consumer notices a problem, he/she comes to action. The bigger the problem is, the higher the motivation, ability, and opportunity to the consumer. For example, a consumer feels hungry and decides to order food.
