Contemporary models of consumer decision-making explain how modern consumers make choices in an environment influenced by digital technology, social media, online reviews, emotions, social groups, experiences, and changing market conditions. Unlike traditional models, contemporary approaches recognise that decision-making is not always linear or completely rational. Consumers may move repeatedly between information search, evaluation, purchase, and post-purchase stages. The following models provide important perspectives for understanding modern consumer behaviour.
1. Consumer Decision Journey Model
The Consumer Decision Journey Model explains consumer decision-making as a continuous journey involving different stages of interaction with a brand. Consumers may initially become aware of a product, consider several alternatives, make a purchase, experience the product, and develop post-purchase attitudes. However, unlike traditional linear models, consumers can move backward and forward between these stages.
The journey commonly includes initial consideration, active evaluation, purchase, post-purchase experience, and loyalty. During active evaluation, consumers may search websites, read reviews, compare prices, ask friends for recommendations, and watch product demonstrations. After purchasing, their experience can influence whether they repurchase, recommend the brand, or consider competitors.
Digital technology has made this journey more complex. Consumers can encounter brands through social media, search engines, online advertisements, influencers, mobile applications, and review platforms. A consumer may see an advertisement on Instagram, search for the product online, compare prices on different websites, watch YouTube reviews, and finally purchase from an online marketplace.
Example: A consumer planning to purchase a smartphone may initially consider several brands. After reading online reviews and comparing specifications, the consumer may select one brand. After using the smartphone, a positive experience may encourage another purchase and recommendations to friends.
The model is important for marketers because it encourages them to focus on the entire consumer journey rather than only the final purchase. Businesses need to provide useful information during evaluation, convenient purchasing processes, excellent customer experiences, and effective post-purchase support.
The model also highlights the importance of customer touchpoints. Every interaction can influence future decisions. Positive experiences can strengthen loyalty, while negative experiences can encourage switching.
2. Stimulus-Organism-Response Model
The Stimulus-Organism-Response Model explains consumer behaviour through the relationship between external stimuli, internal psychological processes, and behavioural responses. It proposes that consumers encounter different environmental or marketing stimuli, which influence their internal thoughts and emotions and eventually produce a behavioural response.
Stimuli may include advertising, product design, pricing, packaging, store atmosphere, website design, music, colours, promotional offers, social media content, and recommendations. These external factors are processed internally by consumers through perceptions, emotions, motivation, attitudes, and beliefs. The internal reaction can then lead to behaviours such as purchasing, browsing, sharing, accepting, or rejecting an offer.
For example, an attractive online advertisement may capture a consumer’s attention. The consumer may develop curiosity and positive feelings toward the product. After exploring the product page and perceiving it as valuable, the consumer may decide to purchase it.
The model is particularly useful for understanding retail and digital environments. Businesses carefully design physical stores and websites to create favourable psychological responses. Lighting, layout, colours, music, images, navigation, and personalised recommendations can influence consumer perceptions and emotions.
Example: A clothing website uses high-quality product images, personalised recommendations, limited-time discounts, and easy navigation. These stimuli may create excitement and perceived value in the consumer, increasing the likelihood of purchase.
The model also helps explain impulse buying. Promotional displays, attractive packaging, limited-time offers, and emotional advertising can create psychological reactions that encourage immediate purchases without extensive evaluation.
3. Theory Of Planned Behaviour
The Theory of Planned Behaviour explains consumer decision-making through three major factors: attitude, subjective norms, and perceived behavioural control. These factors influence a consumer’s behavioural intention, which can ultimately influence actual behaviour.
Attitude refers to the consumer’s positive or negative evaluation of a particular behaviour. For example, a consumer may believe that purchasing an electric vehicle is environmentally beneficial and economically useful. Subjective norms refer to perceived social pressure from people who are important to the consumer, such as family members, friends, colleagues, or social groups. Perceived behavioural control refers to the consumer’s belief that they have the resources, ability, opportunity, and control necessary to perform the behaviour.
These three factors influence behavioural intention. A strong intention generally increases the likelihood of actual behaviour, although external barriers can prevent consumers from acting on their intentions.
Example: Consider a consumer planning to purchase an electric scooter. The consumer may have a positive attitude because electric scooters are environmentally friendly and economical. Friends and family may also support the decision, creating positive subjective norms. If the consumer believes that the scooter is affordable and charging facilities are available, perceived behavioural control will be high. These factors can create a strong intention to purchase.
The theory is useful for marketers because it helps identify why consumers may or may not intend to purchase a product. Businesses can improve attitudes through information and demonstrations, influence social norms through testimonials and influencers, and increase perceived control by providing financing, convenient availability, easy payment options, and clear instructions.
The model is particularly useful in understanding sustainable products, health-related behaviours, technology adoption, financial services, and socially influenced purchases.
4. Engel-Blackwell-Miniard Model
The Engel-Blackwell-Miniard Model provides a comprehensive explanation of consumer decision-making. It describes purchasing as a process involving problem recognition, information search, evaluation of alternatives, purchase, consumption, and post-purchase evaluation. The model also recognises the influence of individual differences, environmental factors, memory, motivation, attitudes, and external information.
The process begins when consumers recognise a need or problem. They then search for information using internal memory and external sources. After collecting information, consumers evaluate different alternatives according to relevant criteria such as price, quality, features, convenience, and brand reputation. They then make a purchase decision and consume the product. Post-purchase evaluation determines whether they experience satisfaction or dissatisfaction.
Example: A student looking for a laptop may recognise the need for a computer for academic work. The student searches online, asks friends for recommendations, reads reviews, compares prices, and evaluates different brands. After purchasing a laptop, the student evaluates its performance. If satisfied, the student may recommend the brand and consider purchasing it again in the future.
The model recognises that consumer decisions are influenced by both internal and external factors. Internal factors include motivation, personality, learning, attitudes, and memory. External influences include culture, family, social groups, marketing activities, economic conditions, and situational factors.
The model is useful for marketers because it provides opportunities to influence consumers at different stages. Advertising can stimulate need recognition, websites can provide information, product demonstrations can support evaluation, convenient distribution can facilitate purchasing, and after-sales service can improve post-purchase satisfaction.
The model also recognises that consumer decisions may differ depending on involvement, product type, perceived risk, and individual circumstances.
5. Digital Consumer Decision-Making Model
The Digital Consumer Decision-Making Model explains how technology and online platforms influence modern purchasing behaviour. Consumers today can search for information, compare products, read reviews, watch demonstrations, communicate with other customers, and complete purchases through digital channels.
The digital decision process may involve online awareness, information search, comparison, evaluation, purchase, digital experience, and post-purchase engagement. Consumers may use search engines, social media, e-commerce websites, mobile applications, online reviews, influencers, and recommendation systems throughout the process.
Unlike traditional purchasing, consumers can access information almost instantly and compare numerous alternatives. They can also move between online and offline channels. For example, a consumer may see a product in a physical store, research its price online, read reviews, and then purchase it through an e-commerce platform.
Example: A consumer interested in buying headphones may watch YouTube reviews, compare prices on different websites, check customer ratings, view social media recommendations, and finally order the preferred model online.
Digital platforms also create opportunities for personalised decision-making. Recommendation algorithms can suggest products based on browsing history, previous purchases, and consumer preferences. Reviews and ratings provide social proof that can influence trust and purchase intentions.
For marketers, the model highlights the importance of maintaining consistent information and experiences across digital touchpoints. Businesses need user-friendly websites, accurate product descriptions, secure payment systems, responsive customer service, and effective digital communication.
Post-purchase behaviour is also important. Consumers can immediately review products, share experiences, upload photographs, or recommend brands online. Positive experiences can increase visibility and advocacy, while negative experiences can spread quickly.
The Digital Consumer Decision-Making Model therefore reflects the increasing importance of technology in consumer behaviour. It demonstrates that modern consumers are more informed, connected, interactive, and capable of influencing other consumers. Businesses must therefore manage the complete digital customer journey rather than focusing only on the final transaction.
6. Social Influence Model
The Social Influence Model explains how consumers’ purchasing decisions are affected by other people and social groups. Consumers do not make decisions independently; family members, friends, colleagues, opinion leaders, influencers, online communities, and reference groups can influence their preferences and behaviour.
Social influence may occur through recommendations, imitation, social approval, group expectations, reviews, testimonials, and shared experiences. Consumers may select products because they believe others consider them desirable or because the products help them express their social identity.
Example: A young consumer may purchase a particular pair of sports shoes after seeing friends wearing the same brand and following recommendations from a popular sports influencer. Positive online reviews from other users may further strengthen the consumer’s confidence in the decision.
Social proof is particularly important in digital environments. Ratings, likes, shares, comments, testimonials, and user-generated content can provide signals about product popularity and credibility. Consumers may perceive products with many positive reviews as safer or more desirable.
Family influence is also important. Family members can influence decisions regarding food, education, automobiles, housing, financial products, and household goods. Similarly, colleagues and professional networks may influence technology, clothing, services, and lifestyle choices.
Marketers use social influence through influencer marketing, referral programmes, testimonials, online communities, user-generated content, and social media campaigns. Businesses can encourage satisfied customers to share experiences and recommendations.
7. Experiential Decision-Making Model
The Experiential Decision-Making Model focuses on the importance of consumer experiences in purchasing and consumption. It suggests that consumers may select products not only for functional benefits but also for pleasure, enjoyment, emotional satisfaction, sensory stimulation, convenience, and memorable experiences.
The model is especially relevant to products and services where experience is an important part of value. These include tourism, hospitality, entertainment, restaurants, fashion, luxury products, retail stores, and lifestyle brands. Consumers may evaluate how a product makes them feel rather than considering only its technical characteristics.
Example: A consumer may choose a particular restaurant because of its atmosphere, music, interior design, service, food presentation, and overall experience rather than simply choosing the cheapest restaurant.
Businesses can influence experiences through store atmosphere, packaging, website design, product demonstrations, personalised services, employee interactions, and entertainment. Sensory elements such as colours, sounds, smells, textures, and visual presentation can contribute to the overall experience.
Positive experiences can generate satisfaction, emotional attachment, repeat purchases, and loyalty. Consumers may also share memorable experiences through social media, creating additional exposure for the brand.
The model also explains why consumers sometimes choose premium products despite cheaper alternatives. A premium product may provide status, enjoyment, exclusivity, or emotional benefits that consumers value beyond basic functionality.
8. Post-Purchase And Relationship Model
The Post-Purchase and Relationship Model views consumer decision-making as a continuing process that extends beyond the purchase. After purchasing and using a product, consumers evaluate whether the experience met their expectations. This evaluation can lead to satisfaction, dissatisfaction, loyalty, complaints, recommendations, repeat purchases, or brand switching.
Post-purchase behaviour is influenced by product performance, service quality, perceived value, expectations, and the overall consumption experience. If performance meets or exceeds expectations, consumers are more likely to experience satisfaction. Positive experiences can strengthen trust and encourage future purchases. If performance falls below expectations, dissatisfaction may result.
Example: A consumer purchases a smartphone and finds that it performs better than expected. The consumer may post a positive review, recommend the product to friends, purchase accessories from the same brand, and consider buying the brand’s next model.
Businesses can influence post-purchase behaviour through warranties, customer support, loyalty programmes, personalised communication, feedback systems, and effective complaint handling. Service recovery is particularly important when consumers experience problems. A quick replacement or refund may restore confidence and prevent customers from switching to competitors.
Relationship management aims to transform individual transactions into long-term relationships. Businesses can maintain relationships by understanding customer preferences, offering relevant products, rewarding loyalty, and communicating consistently.
Digital platforms have increased the importance of post-purchase behaviour because consumers can immediately share experiences through reviews and social media. Positive feedback can influence potential buyers, while negative feedback can damage brand reputation.
