Howard Sheth Theory Variables Explained

The Howard Sheth Theory explains buyer behaviour using a complex model. It identifies four primary sets of variables that interact to influence a purchase decision.

Identifying the Four Variable Sets

According to the Howard Sheth Theory, the four key sets of variables determining buyer behaviour are:

• Stimulus Input Variables: These are the external stimuli from the buyer's environment, such as advertising, product information, and salesperson interactions.
• Internal Behaviour of Buyer (Overt & Covert Constructs): This represents the buyer's internal state and decision-making processes. It includes psychological variables like motivation, perception, attitudes, learning, and personality.
• Exogenous Variables: These are external factors that influence the buyer's behaviour but are not part of the core stimulus-response mechanism. Examples include social status, culture, and time pressure.
• Response Output Variables: These are the observable outcomes or actions taken by the buyer, such as the decision to purchase, the brand chosen, the quantity bought, and post-purchase satisfaction.

Therefore, Option D correctly lists these four sets: Stimulus input variable, internal behaviour of buyer, exogenous variables, and response output variables.
