The Nicosia Model of Consumer Decision Making

Published in 1966 by Francesco M. Nicosia in his landmark book Consumer Decision Processes, the Nicosia Model was one of the very first comprehensive systems models developed to explain how commercial advertising influences consumer minds and results in purchase action.

1. Core Architecture of the Nicosia Model

The Nicosia Model is distinctive because it focuses specifically on the relationship between a business firm and its potential consumers.

It uses a circular flow chart structure, showing how the firm’s advertising message influences the consumer, leads to purchase, and feeds back into both the consumer’s memory and the firm’s sales logs.

2. The Four Fields of the Nicosia Model

Field 1: Message Source and Consumer’s Predisposition

Divided into two subfields:

• Subfield 1 (Firm’s Attributes): The firm’s product characteristics, brand reputation, pricing, and the specific advertising message it broadcasts.
• Subfield 2 (Consumer’s Attributes): The consumer’s personal psychological makeup (personality, values, past experiences).
• Output of Field 1: The interaction between the firm’s advertising message and the consumer’s personality creates an Attitude / Predisposition toward the product.

Field 2: Search and Evaluation

• If the attitude formed in Field 1 is positive, the consumer searches for information regarding the brand and evaluates competing alternatives.
• The consumer evaluates product attributes against their personal needs.
• Output of Field 2: Motivation to buy the specific brand.

Field 3: The Act of Purchase

• Motivation is transformed into actual Purchase Action.
• The consumer visits a retail store or opens an e-commerce app and purchases the item.
• Output of Field 3: Purchasing Behavior.

Field 4: The Feedback Loops

The circular feedback mechanism operates in two directions:

1. Feedback to the Consumer (Storage & Experience): The consumer uses the product. The resulting satisfaction or dissatisfaction is stored in memory and modifies the consumer’s future predisposition for subsequent purchases.
2. Feedback to the Firm (Sales Data): The purchase registers as sales revenue. The firm analyzes sales reports and customer reviews to adjust its future advertising campaigns.

3. Evaluation: Strengths and Limitations

Strengths:

• First model to recognize consumer decision making as a continuous circular communication loop between firm and consumer.
• Clearly illustrates how corporate advertising influences consumer attitudes and buying actions.
• Explicitly models post-purchase feedback loops to both consumer memory and corporate strategy.

Limitations:

• Assumes that the consumer has no prior knowledge or predisposition about the product before receiving the advertisement (rare in modern digital eras).
• Does not clearly explain what happens internally in the consumer’s mind during the evaluation phase (simplifies the “black box”).
• Less applicable to routine, low-involvement grocery purchases where advertising plays a secondary role to habit.

4. Key Takeaways & Exam Summary

• The Nicosia Model (1966) models the interactive communication loop between a firm and its consumers.
• Consists of Four Fields:
  • Field 1: Firm’s attributes + Consumer’s attributes ightarrow Attitude.
  • Field 2: Information search & alternative evaluation ightarrow Motivation.
  • Field 3: Act of purchase.
  • Field 4: Feedback (Consumer memory + Firm sales data).
• The model is circular, showing that purchase experience alters future consumer predisposition and corporate marketing.
