Summary
This study aims to better understand why humans make nonverbal sounds like screams, laughter, and grunts, and how our bodies react when we make them. Researchers will record 2000 participants making various vocal sounds and measure things like heart rate and skin temperature. The goal is to learn more about the nature and function of these signals, not to test a treatment.
