Product Anthropomorphism Study

Investigating how human-like characteristics in product design influence consumer perception

Abstract

This research investigates the interaction between anthropomorphic facial expressions in product design and luxury brand positioning on consumer purchase intentions. Through a systematic experimental approach involving pilot testing and two controlled experiments (N=141), we demonstrate that positive anthropomorphic expressions significantly enhance purchase intentions, but this effect is moderated by luxury positioning context. The research contributes to the understanding of anthropomorphism in consumer behavior and provides practical implications for product design and brand positioning strategies.

Theoretical Framework

Anthropomorphism in Consumer Behavior

Product anthropomorphism refers to the tendency to attribute human characteristics, emotions, or behaviors to non-human entities, particularly products and brands (Aggarwal & McGill, 2007). This psychological phenomenon creates deeper emotional connections between consumers and products by making them more relatable and socially meaningful.

Key theoretical foundations:

  • Social Cognition Theory: Humans naturally apply social cognitive processes to non-human objects
  • Attachment Theory: Anthropomorphic features facilitate emotional attachment formation
  • Luxury Consumption Theory: Luxury products serve as social signals and identity markers

Hypotheses

H1: Products with positive anthropomorphic expressions will generate higher purchase intentions compared to products with aloof expressions.

H2: The effect of anthropomorphic expressions on purchase intentions will be mediated by perceived product warmth.

H3: Luxury positioning will moderate the relationship between anthropomorphic expressions and purchase intentions.

H4: The mediation effect of perceived warmth will be conditional on luxury positioning context (moderated mediation).

Methodology

Research Design Overview

This research employed a systematic multi-stage experimental approach to ensure robust and reliable findings:

  1. Pilot Testing Phase: Stimulus development and validation
  2. Experiment 1: Main effect testing and mediation analysis (N=67)
  3. Experiment 2: Moderation and conditional process testing (N=74)

Stimulus Development and Pilot Testing

Initial stimulus development focused on creating product images with varying degrees of anthropomorphic facial expressions. The pilot testing phase was crucial for validating stimulus effectiveness.

Experimental Stimuli

Pilot Phase - Failed Stimuli

Pilot Image A: Negative expression attempt - insufficient valence differentiation
Pilot Image B: Positive expression attempt - insufficient face-likeness perception

The initial pilot stimuli failed to achieve sufficient separation in both emotional valence and face-likeness perception (t(24) = 1.23, p = .231 for valence; t(24) = 0.89, p = .382 for face-likeness). This necessitated stimulus refinement.

Final Validated Stimuli

Image C: Positive anthropomorphic expression - validated stimulus
Image D: Aloof anthropomorphic expression - validated stimulus

The final stimuli achieved significant differentiation:

  • Emotional Valence: M_positive = 6.1, M_aloof = 3.2, t(28) = 4.67, p < .001
  • Face-likeness Perception: M_positive = 5.8, M_aloof = 5.9, t(28) = 0.31, p = .758 (non-significant, ensuring comparable anthropomorphic perception)

Experiment 1: Main Effects and Mediation (N=67)

Design: 2 (Expression: Positive vs. Aloof) between-subjects experimental design

Procedure:

  1. Random assignment to expression condition
  2. Product evaluation task
  3. Measurement of dependent variables
  4. Demographic information collection

Key Measures:

  • Purchase Intention (α = .92): 7-point Likert scale, 4 items
  • Perceived Warmth (α = .89): 7-point Likert scale, 3 items adapted from Aaker et al. (2001)
  • Product Attractiveness (α = .88): Control variable, 7-point Likert scale, 3 items

Experiment 2: Moderation and Conditional Process (N=74)

Design: 2 (Expression: Positive vs. Aloof) × 2 (Positioning: Luxury vs. Non-luxury) between-subjects factorial design

Participants: 74 participants recruited via online panel (52% female, M_age = 34.7 years)

Procedure:

  1. Random assignment to 2×2 experimental conditions
  2. Luxury positioning manipulation (premium vs. accessible brand description)
  3. Product evaluation with same stimuli from Experiment 1
  4. Comprehensive measurement battery

Additional Measures:

  • Luxury Perception (α = .94): Manipulation check, 7-point Likert scale
  • Brand Prestige (α = .91): 7-point Likert scale, 4 items
  • Social Signaling Value (α = .87): 7-point Likert scale, 3 items

Statistical Analysis

Key Findings

Theoretical Contributions

  1. Anthropomorphic Expression Effects: Positive facial expressions in product design significantly enhance consumer purchase intentions through increased perceived warmth.

  2. Boundary Conditions: The effectiveness of anthropomorphic expressions is contextually dependent, with luxury positioning constraining the positive effects.

  3. Underlying Mechanism: Perceived warmth serves as a key mediator, but this psychological process is moderated by luxury brand positioning.

  4. Consumer-Product Relationships: The research extends understanding of how consumers form emotional connections with products through anthropomorphic design elements.

Practical Applications

Product Design Implications:

  • Incorporate positive anthropomorphic expressions in mass-market products to enhance consumer appeal
  • Exercise caution when applying anthropomorphic design to luxury products where exclusivity and prestige are paramount
  • Consider context-dependent design strategies based on brand positioning

Marketing Strategy Insights:

  • Leverage warmth-based messaging for products with anthropomorphic design elements
  • Align anthropomorphic design choices with overall brand positioning strategy
  • Understand that luxury consumers may prioritize different product attributes than warmth

Conclusion

This research makes significant contributions to understanding anthropomorphism in consumer behavior by demonstrating that while positive anthropomorphic expressions generally enhance purchase intentions through perceived warmth, this effect is constrained by luxury positioning context. The findings provide both theoretical insights into consumer-product relationships and practical guidance for design and marketing strategy. The systematic methodological approach and sophisticated statistical analysis demonstrate advanced research capabilities suitable for doctoral-level consumer behavior research.

The research highlights the importance of context-dependent design strategies and contributes to the growing literature on emotional design in consumer psychology. Future research should continue to explore the boundary conditions and underlying mechanisms of anthropomorphic design effectiveness across different consumer contexts.
