Reference Group: A social group that influences individual attitudes and behavior, including aspirational, associative, and dissociative groups.
Mental Accounting: The tendency to treat money differently depending on its source, intended use, or mental category.
Social Proof: The tendency to look to others' behavior as a guide for one's own, especially in uncertain situations.

Introduction to Consumer Psychology

Consumer psychology examines how thoughts, beliefs, feelings, and perceptions influence purchasing and consumption behavior. This field applies psychological principles to understand why people buy what they buy, how they make decisions, and how marketing influences behavior.

Consumer Decision-Making

Traditional Decision-Making Model: 1. Problem Recognition 2. Information Search 3. Alternative Evaluation 4. Purchase Decision 5. Post-Purchase Evaluation

Types of Decision-Making: - Extended: High involvement, extensive research (cars, homes) - Limited: Moderate effort (appliances, clothing) - Habitual: Low involvement, routine (groceries) - Impulse: Unplanned, emotional purchases

Bounded Rationality: Consumers satisfice rather than optimize due to cognitive limitations.

Dual-Process Theory: System 1 (fast, intuitive) and System 2 (slow, deliberate) processing in consumer choices.

Motivation and Needs

Maslow's Hierarchy in Marketing: - Physiological: Food, shelter, health products - Safety: Insurance, security systems - Belonging: Social media, fashion, clubs - Esteem: Luxury goods, status symbols - Self-Actualization: Education, experiences

Hedonic vs. Utilitarian Consumption: - Hedonic: Pleasure, fun, fantasy (entertainment, luxury) - Utilitarian: Functional, practical (tools, necessities)

Motivation Conflicts: - Approach-Approach: Choosing between two desirable options - Approach-Avoidance: Product has both positive and negative aspects - Avoidance-Avoidance: Choosing between two undesirable options

Perception and Attention

Sensory Marketing: - Visual: Color psychology, package design - Auditory: Music tempo, brand sounds - Olfactory: Scent marketing in retail - Tactile: Product texture, packaging feel - Gustatory: Taste testing, flavor psychology

Selective Attention: - Consumers filter most marketing messages - Novel, relevant, or intense stimuli capture attention

Subliminal Perception: Below-threshold stimuli have minimal effect (contrary to popular belief).

Perceptual Organization: - Figure-ground relationship - Gestalt principles in advertising - Perceptual positioning maps

Attitudes and Persuasion

Attitude Components (ABC): - Affective: Feelings toward product/brand - Behavioral: Actions and intentions - Cognitive: Beliefs and knowledge

Elaboration Likelihood Model: - Central Route: Careful argument processing (high involvement) - Peripheral Route: Heuristic cues (low involvement)

Persuasion Principles (Cialdini): - Reciprocity: Give to receive - Commitment/Consistency: Honor prior commitments - Social Proof: Follow others' behavior - Authority: Trust experts - Liking: Buy from those we like - Scarcity: Value limited availability - Unity: Shared identity increases influence

Behavioral Economics in Marketing

Key Biases Exploited in Marketing:

Anchoring: Initial price sets expectations (was $100, now $60)

Framing: Same information presented differently (90% fat-free vs. 10% fat)

Loss Aversion: Emphasize what consumers might lose

Decoy Effect: Third option makes target option more attractive

Default Effect: Pre-selected options are more likely chosen

Mental Accounting: Separate mental budgets for categories

Endowment Effect: Owning something increases its perceived value

Sunk Cost Fallacy: Continuing due to prior investment

Choice Overload: Too many options can paralyze decision-making

Central vs. Peripheral Route Processing

Two routes to persuasion in the Elaboration Likelihood Model.

	Central Route	Peripheral Route
Processing	Careful, thoughtful	Superficial, heuristic
Focus	Argument quality	Peripheral cues (source, visuals)
Involvement	High	Low
Attitude change	Durable, resistant to change	Temporary, susceptible to change
Predictive of behavior	Strongly	Weakly
