Perception

1. Big Idea

Perception is the process by which consumers select, organise, and interpret sensory information into meaningful experience. Marketing stimuli matter only after consumers notice and interpret them.

2. Exam Focus

Expect questions about attention, interpretation, thresholds, selective perception, adaptation, and perceptual mapping. You should be able to explain how a marketer can alter stimulus design to influence perception.

3. Key Concepts

Important concepts include sensation versus perception, sensory systems, exposure, attention, interpretation, absolute threshold, differential threshold, Weber's Law, subliminal perception, selective perception, and perceptual maps.

4. Core Framework

Perception normally moves from exposure to attention and then interpretation. Each stage can fail: consumers may not encounter the stimulus, may ignore it, or may interpret it differently from the marketer's intention.

5. Marketing Example

A price discount works only if the change is above the just noticeable difference. A tiny package-size reduction may escape attention, while a redesigned shelf display may increase exposure and attention.

6. Common Confusions

Absolute threshold is the minimum level needed to detect a stimulus at all. Differential threshold is the minimum change needed to notice a difference between two stimuli.

7. Active Recall Prompts

Use these prompts for retrieval practice.

• •How does Weber's Law guide price or package changes?
• •Why can two consumers interpret the same ad differently?
• •What is the difference between selective exposure and selective attention?

8. 15-Minute Review Plan

Spend five minutes defining the thresholds, five minutes creating a perceptual map for two brands, and five minutes explaining a real ad through exposure-attention-interpretation.
