Lateral feature displacement and perceived facial attractiveness

Area of Science:

• Psychology
• Perception Science
• Human-Computer Interaction

Background:

• Facial attractiveness is influenced by symmetry and feature arrangement.
• Previous research suggests symmetry enhances facial appeal.

Purpose of the Study:

• To investigate the impact of lateral facial feature displacement on attractiveness ratings.
• To determine if symmetrical faces are rated higher than normal faces.
• To assess sensitivity to feature displacement originating from symmetrical versus normal faces.

Main Methods:

• Lateral displacement of vertically adjacent facial features in normal and symmetrical faces.
• Undergraduate participants rated the attractiveness of manipulated facial images.
• Two experiments were conducted, with the second controlling for displacement distance from symmetry.

Main Results:

• Symmetrical faces were not rated as more attractive than normal faces.
• Faces with alternating feature displacements were rated less attractive.
• Displacements from symmetrical faces were perceived more negatively than from normal faces, indicating heightened sensitivity.

Conclusions:

• Facial symmetry alone does not guarantee higher attractiveness ratings.
• Deviations from facial symmetry, particularly alternating displacements, significantly decrease perceived attractiveness.
• The human visual system exhibits greater sensitivity to facial feature displacement when it occurs from a symmetrical baseline.
