Peer audience effects on children's vocal masculinity and femininity.

Area of Science:

• Child Psychology
• Acoustic Phonetics
• Social Interaction

Background:

• Children aged 8+ strategically manage their public image through self-description to align with peer preferences.
• The vocal medium of self-presentation in children remains under-explored.
• Peer audience effects on children's vocal productions are significant for social dynamics.

Purpose of the Study:

• To investigate how peer audience gendered interests influence children's vocal self-presentation.
• To examine acoustic changes in children's voices based on audience and message content.
• To understand the role of vocal modulation in children's friendship-making strategies.

Main Methods:

• Fifty-six children (8-10 years) impersonated a fictional child interacting with same-sex peers (rugby or ballet interests).
• Participants read masculine, feminine, and gender-neutral statements aloud to hypothetical audiences.
• Acoustic analyses measured fundamental frequency and formant frequency spacing of vocal productions.

Main Results:

• Children selected self-descriptive statements aligning with audience interests (masculine for rugby, feminine for ballet).
• Vocal analyses revealed significant voice feminization when speaking to ballet peers and voice masculinization when speaking to rugby peers.
• Both sexes feminized their voices when uttering feminine statements compared to masculine or neutral ones.

Conclusions:

• Children actively modulate their vocal characteristics to suit peer audience gendered interests, demonstrating sophisticated social-cognitive abilities.
• Acoustic qualities of children's voices play a crucial, yet often overlooked, role in peer interactions and social navigation.
• Findings highlight the importance of considering vocal behavior in the study of children's self-presentation and social development.
