Screaming in pain and fear serves specific evolutionary and communicative functions
the verdict
SUPPORTED
the evidence backs this
confidence 84/100
Converging evidence from animal and human studies demonstrates that screams and distressing nonverbal vocalizations utilize specific acoustic features, such as nonlinear phenomena, to reliably communicate pain and fear, elicit rapid behavioral responses, and serve adaptive evolutionary functions.
