A recent study published in the journal Evolution and Human Behavior found that people do not rely solely on facial features or body shape when forming impressions of others. Instead, the voice plays an independent role in conveying information about its owner.

The findings showed that facial and body attractiveness are often correlated, while the voice provides different signals that may not be linked to a person’s physical appearance.
Evolutionary psychology suggests that physical traits convey information about health and biological fitness to potential partners or competitors. People therefore often assess physical attractiveness or signs of dominance to infer underlying traits in others, such as strength or health, according to Al Arabiya Net.
The study was based on two main theoretical frameworks. The first is the “single ornament hypothesis,” which suggests that different physical traits are shaped by common biological factors, causing the face and body to convey similar information about health and genetic fitness.
The second is the “multiple messages hypothesis,” which proposes that each physical trait can convey different and independent information.
To investigate this, a research team led by Tobias Kordsmeyer of the University of Göttingen independently assessed faces, bodies and voices to determine how participants perceived attractiveness, health and dominance through these different signals.
The results showed clear positive correlations between facial and body assessments. People who received high ratings for facial attractiveness and health were also generally rated highly in terms of their body appearance. This pattern was observed in both men and women.
The researchers found that the relationship between voice ratings and assessments of the face or body was very limited. In other words, a person whose face or body is perceived as attractive or healthy does not necessarily receive the same assessment for their voice.
The researchers said this finding supports the “multiple messages hypothesis,” suggesting that the voice functions as an independent communication channel that provides additional information rather than simply repeating what visual signals convey. This means people may rely on the voice for cues that differ from those they derive from physical appearance.
However, the researchers noted that the study relied on subjective impressions of attractiveness, health and dominance and did not compare them with direct medical or physical measurements. Therefore, the findings reflect how people perceive others rather than confirming their actual physical characteristics.
The research team said future studies could help clarify the biological links between these traits by tracking hormonal changes during adolescence, as well as examining other signals such as body odor and movement patterns. Such research could provide a deeper understanding of the mechanisms underlying nonverbal human communication.
