Different Vocal Parameters Predict Perceptions of Dominance and Attractiveness
Human Nature (Hawthorne, N.Y.)
|January 8, 2011
Summary
Men's vocal characteristics, like fundamental frequency (F0) and formant dispersion (Df), influence perceptions of dominance and attractiveness. These vocal cues provide distinct information to potential mates and competitors.
Area of Science:
- Evolutionary Psychology
- Acoustic Phonetics
- Human Communication
Background:
- Previous research linked low mean fundamental frequency (F0) in men's voices to increased perceived dominance and attractiveness.
- These findings were primarily based on standardized speech, limiting ecological validity.
Purpose of the Study:
- To investigate the relationship between vocal parameters and dominance/attractiveness judgments using natural speech from a social interaction.
- To explore how different vocal parameters (F0, F0 variation, intensity, duration, formant dispersion) predict perceptions of physical and social dominance in men.
- To assess women's perceptions of male voice desirability across different menstrual cycle phases and relationship contexts.
Main Methods:
- Analysis of male voices from an unscripted dating game, with judges rating dominance and attractiveness.
- Measurement of five vocal parameters: mean F0, F0 variation, intensity, utterance duration, and formant dispersion (Df).
- Multiple regression analyses to determine the independent contribution of each vocal parameter and word content.
Main Results:
- Physical dominance was predicted by low F0 variation and dominant word content.
- Social dominance was solely predicted by socially dominant word content.
- Attractiveness ratings were influenced by low mean F0, low Df, high intensity, and attractive word content, with Df being particularly attractive to fertile-phase women.
Conclusions:
- Vocal parameters significantly contribute to perceptions of male dominance and attractiveness in naturalistic settings.
- Different vocal cues may be prioritized by competitors and mates due to the distinct information they convey.
- Findings highlight the complex interplay between vocal acoustics, content, and social perception in mate choice and competition.

Personality traits are fundamental in shaping social perception and influencing interpersonal relationships. Certain traits, such as agreeableness and extraversion, contribute positively to social interactions, whereas others, such as narcissism, have complex and often contradictory effects on how individuals are perceived over time.The Role of Agreeableness and ExtraversionAgreeableness and extraversion are associated with higher levels of interpersonal attractiveness and likability.
01:24Facial Feedback Hypothesis
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role of...

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Various factors, including the type of relationship, gender, and duration of the relationship, influence the perception of desirable characteristics in others. While certain traits such as trustworthiness, cooperativeness, agreeableness, and extraversion are universally valued across all relationships, other characteristics are context-dependent and gain prominence based on specific relational dynamics.Universal and Context-Dependent TraitsTrustworthiness and cooperativeness are fundamental...
01:23Factors Influencing Attraction III: Similarity
The similarity hypothesis suggests that individuals are more likely to form relationships with others who share similar attitudes, beliefs, values, and interests. This concept has been widely studied in social psychology, demonstrating that perceived similarity fosters interpersonal attraction. In an experiment supporting this hypothesis, participants were presented with fabricated information indicating that strangers held attitudes similar to their own. The results showed that participants...
