Consumer Behaviour and the Decision Process
Week 2 walks through the five-stage consumer decision-making process and the psychological, social and situational factors that shape it, including involvement and post-purchase dissonance. This is the framework Group B reflects on in the 500-word Learning Reflection, where you map a personal purchase onto the decision stages rather than describing a product. Ground it in the Week 2 podcast and the sustainability-of-luxury demo case.
What this chapter covers
- 01The five-stage decision process: need recognition → information search → evaluation of alternatives → purchase → post-purchase
- 02Functional vs psychological needs; the consideration (evoked) set and evaluative criteria
- 03Internal vs external information search; search effort rises with risk and involvement
- 04Psychological factors: motivation (Maslow's hierarchy), perception, learning, attitudes
- 05Social factors: family, reference groups, culture/sub-culture; opinion leaders and word of mouth
- 06Situational factors: purchase/shopping situation, time pressure, mood
- 07Involvement and buying types (extended, limited, habitual); post-purchase cognitive dissonance
- 08Consumer roles (initiator, influencer, decider, buyer, user) and the user-expert idea
Applied: mapping a purchase onto the consumer decision process
- +1Need recognition: the current laptop is too slow for coursework — a gap between the actual and desired state triggers the process (a functional need).
- +1Information search: an external search — a friend's online recommendation, reviews and marketplace listings — supplements internal memory; higher perceived (financial) risk drives more search.
- +1Evaluation of alternatives: compare a shortlist (the consideration set) on evaluative criteria — price, warranty, condition, specs — using price-vs-performance as the determinant attribute.
- +1Purchase and post-purchase: choose the refurbished model, then experience post-purchase cognitive dissonance (“did I trust a refurbished unit?”), resolved by the returns policy and positive early use.
- +1Factors: a psychological factor = perceived risk/attitude toward refurbished goods; a social factor = the friend's recommendation acting as word of mouth from a reference group.
Key terms
- Consumer decision process
- The five stages a buyer moves through: need recognition, information search, evaluation of alternatives, purchase, and post-purchase evaluation.
- Need recognition
- Perceiving a gap between an actual and a desired state; needs may be functional (utility) or psychological (emotional/social/self-expression).
- Consideration (evoked) set
- The shortlist of alternatives a consumer actually weighs, compared on evaluative criteria / determinant attributes.
- Post-purchase cognitive dissonance
- Buyer's remorse — doubt after a high-involvement purchase — which marketers reduce with reassurance, guarantees and follow-up.
- Involvement
- The degree of interest in and importance attached to a purchase; high involvement drives extended problem solving, low involvement habitual buying.
- Social factors
- Family, reference groups and culture/sub-culture influences on choice, including opinion leaders and word of mouth.
Consumer Behaviour and the Decision Process FAQ
What is the difference between a functional and a psychological need?
A functional need is about performance or utility — a laptop that runs your software. A psychological need is emotional, social or self-expressive — the pride, belonging or identity a purchase signals. Good reflections show a purchase satisfying both, which is why the decision-process exemplars split needs this way.
Why does post-purchase matter if the sale is already made?
Because satisfaction, dissonance and loyalty are decided after purchase, and they drive repeat buying, word of mouth and complaints. Marketers manage the post-purchase stage with reassurance, easy returns and follow-up to reduce cognitive dissonance and build loyalty — a point markers look for in a complete decision-process analysis.
How is Week 2 assessed?
Group B's 500-word Learning Reflection is built on this chapter: you reflect on a personal purchase or consumption experience through the consumer-behaviour framework, adding a cultural or demographic lens and Harvard-referenced context. The skill is reflection and framework application, not product description.
Can Sia help me with the consumer decision process in MARK2012?
Yes, as a study aid. Sia can explain the consumer decision process step by step, walk through a worked application to a real brand, and check whether your reasoning uses the framework correctly for your reflection, presentation or report. It teaches the method and checks your thinking; it does not complete graded assessment for you, and the UNSW academic-integrity policy applies — confirm assessment rules on Moodle.
Assessment move
Practise by narrating your own recent purchases through the five stages until labelling them is automatic, and always attach at least one psychological and one social factor. Keep these mini-reflections in your Week-1 log — one becomes your 500-word submission. Remember the course's rule that reflection means making meaning from experience, not summarising notes or describing a product, and support any market context with Harvard references. Confirm which week your group reflects (Group A vs B) on Moodle.
