24210 Chap.3 Consumer Decision Making: Stages and Psychology
Consumer Decision Making: Stages and Psychology
The decision process
Lecture 3 follows consumers from problem recognition through information search, alternative evaluation within an evoked set, the purchase decision and postpurchase evaluation, where satisfaction, dissatisfaction or cognitive dissonance follows.
The psychology behind it
Each stage is driven by a psychological process: motivation, perception, attitude formation, integration through decision rules, and learning, both behavioural and cognitive.
Attitudes you can change
Multiattribute models weigh beliefs about each attribute by its importance, and four attitude change strategies show where communication can move the result, while empowerment and the AI-driven paradox shape how much consumers trust what they see.

Match three ads to a decision stage and the process behind it
- 1Ad 1 creates a felt gap between the ideal and actual state: problem recognition, driven by motivation.
- 1Ad 3 helps compare brands on evaluative criteria: alternative evaluation, driven by attitude formation.
- 1Ad 2 reassures a buyer after the decision: postpurchase evaluation, driven by learning, and it reduces cognitive dissonance.
Key terms
- Consumer Empowerment
- A consumer’s sense of having more ability than before to produce desired outcomes, through mobile technology and the internet.
- Evaluative Criteria
- The objective or subjective attributes consumers use to compare alternatives, such as price or styling.
- Selective Retention
- The last selective perception process, in which only part of what was attended to and understood is remembered.
Consumer Decision Making: Stages and Psychology FAQ
What are the five stages of consumer decision making?
Problem recognition, information search, alternative evaluation, the purchase decision and postpurchase evaluation. The lecture pairs each with a psychological process, from motivation at the start to learning at the end, so communication aimed at a stage should work through the process that governs it.
What is an evoked set and why does it matter?
It is the set of brands a consumer considers able to meet the need, narrowed from all available brands. Brands outside it are rarely chosen, so much marketing communication simply aims to earn a place in it, which is the point of the Week 3 tutorial question on gaining consideration.
What is cognitive dissonance after a purchase?
It is psychological tension or doubt a consumer may feel after deciding to buy, which leads them to look for supportive information. Communication after the sale, such as reassuring messages and evidence of satisfied owners, exists to reduce it and protect repeat purchase.
How do multiattribute attitude models work?
They treat a brand as a bundle of attributes. Consumers hold beliefs about each attribute and attach importance to it, and the attitude reflects beliefs weighted by importance. Marketers must know which attributes carry weight to predict, and change, the result.
What are the four attitude change strategies?
Change the belief rating on an important attribute, change how important an attribute seems, add a new attribute to the mix, or change beliefs about a competing brand. Each targets a different part of the multiattribute calculation.
Why do marketers prefer cognitive learning theory?
Because it treats consumers as active problem solvers, and the five-stage decision model is built on it. The lecture criticises behavioural learning theory, with its classical and operant conditioning, as too simplistic, too focused on external stimuli and blind to internal psychological processes.
What is the AI-driven paradox in consumer empowerment?
The same technology that empowers consumers can also work against them, through echo chambers, algorithmic bias, deepfakes, privacy worries, information overload and a sense of being watched. The lecture’s answer is transparent, trust-building communication in which AI supports human connection rather than replacing it.
Assessment move
Draw the stage and process ladder from memory, then annotate it with one ad you have seen for each stage. Work two multiattribute comparisons with your own numbers and say which change strategy would help the losing brand most. Link the AI paradox to how your group will keep its campaign transparent. Finish by writing two sentences on how your campaign will earn trust in the face of the AI-driven paradox the lecture describes.
