What are the different types of consumer behaviour?

There are four types of consumer behaviour. They are;

(1) Complex Buying Behaviour: 

Consumers goes through complex buying behaviour when they are highly involved in a purchase and aware of significant differences among brands. Consumers are highly involved when the product is expensive, bought infrequently, risky and self-expensive. Here consumers go through a rational/logical thinking process to collect as much information as possible about the available brands. Behaviour exhibited while purchasing a car is an example of complex buying behaviour.
 

(2) Dissonance Reduction Buying Behaviour: 

Sometimes consumers are highly involved in purchases but see little difference in the brands. After the purchase, they feel that the product does not perform to their expectations. They may think about an alternative brand which has forgone in the brand selection process. As a result, they feel some discomfort. This mental condition is known as Cognitive Dissonance.

(3)Variety Seeking Buying Behaviour: 

Here consumers have a lot more brand options to choose. At the same time, there are significant brand differences. The unit price of the product is low. Consumer involvement is also low. But consumer show brand switching behaviour. They go on changing from one brand to another. They like experiments for the sake of variety of satisfaction. They exhibit variety-seeking behaviour in case of products like soap, detergents, toothpaste, etc. 

(4) Habitual Buying  Behaviour:     

In this situation, consumers buy their products on a regular basis. Brand switching behaviour is quite common here. Variations among brands are significant. Products are usually low priced. Gathering product knowledge is not so important. Consumers show habitual buying behaviour in case of products like salt, matches, etc.
