Physically attractive faces attract us physically.

Area of Science:

• Psychology
• Social Psychology
• Cognitive Neuroscience

Background:

• Facial expressions are crucial for social decision-making, guiding approach or avoidance.
• Facial attractiveness is a significant factor in social perception and interaction.
• Previous research has not fully explored the automatic approach-avoidance tendencies triggered by facial attractiveness.

Purpose of the Study:

• To investigate whether facial attractiveness automatically elicits approach-avoidance behaviors.
• To determine if attractiveness-based approach tendencies are modulated by response outcomes or stimulus inversion.
• To examine implicit approach behaviors towards attractive faces using a force platform.

Main Methods:

• Experiments 1-3 used an approach-avoidance paradigm with attractive and unattractive female faces, without explicit attractiveness ratings.
• Stimulus inversion was used to assess the role of configural processing.
• Experiment 4 employed a passive viewing paradigm with a force platform to measure implicit approach responses.

Main Results:

• Participants showed a bias to select attractive faces more often in Experiments 1-3.
• This attractiveness bias was reduced by face inversion, suggesting configural processing.
• In Experiment 4, participants leaned more towards attractive faces, especially males, indicating an implicit approach tendency.

Conclusions:

• Facial attractiveness automatically activates approach-avoidance tendencies.
• These automatic responses are sensitive to stimulus properties and processing.
• Attractiveness plays a fundamental role in guiding social approach behaviors, independent of explicit evaluation.
