Face perception loves a challenge: Less information sparks more attraction

Area of Science:

• Psychology
• Perceptual Science
• Cognitive Science

Background:

• Hedonic responses in face perception are linked to processing fluency and stimulus clarity.
• The role of objective stimulus quality versus subjective experience in attractiveness judgments is debated.

Purpose of the Study:

• To investigate how reduced visual input (blur, contrast reduction, occlusion) affects perceived facial attractiveness.
• To examine the relationship between processing fluency, goodness-of-fit, and hedonic experience in face perception.

Main Methods:

• Three experiments were conducted using 200 novel female faces.
• Participants rank-ordered faces by attractiveness after manipulations including blurring, contrast reduction, and partial occlusion.
• Objective stimulus quality was systematically degraded.

Main Results:

• Reduced visual input consistently enhanced perceived facial attractiveness.
• Blurring followed an exponential trend, while contrast reduction showed a linear trend in attractiveness.
• Half-occluded faces were rated significantly more attractive, challenging the role of symmetry.

Conclusions:

• Decreased objective stimulus quality can lead to a positive hedonic experience, suggesting enhanced perceptual goodness-of-fit.
• The findings challenge the notion that facial symmetry is inherently attractive, suggesting asymmetry may be unattractive.
