Briefings

Researchers observed that humans frequently use specific nonverbal sounds like laughter, sighs, and screams to communicate feelings without speaking, suggesting these sounds follow unwritten social rules rather than being random. The study highlights how rarely people pause to consciously select the appropriate sound for a given situation, indicating an automatic, rule-based system exists in everyday interactions.

Key points

• Humans frequently use nonverbal sounds such as laughter, sighs, and screams to express feelings without uttering words, indicating a reliance on established social rules for sound selection.
• People rarely pause to consciously decide which sound belongs in a specific situation, suggesting these sounds operate automatically rather than through deliberate thought.

Context and limitations

The study covers only everyday nonverbal sounds and does not include verbal communication, nor does it account for cultural variations in social norms regarding specific sounds.
