Consumer problem recognition occurs when a consumer perceives a significant difference between their desired state of needs being met and the actual state. The desired state is how a consumer wants a need to be satisfied, and is influenced by reference groups, thinking, and financial considerations. The actual state is how needs are currently being met, and can be affected by arousal of needs, previous decisions, culture, and individual development. Whether a consumer takes action depends on factors like their past experiences, characteristics, motives, environmental influences, and past marketing stimuli.
