The emotional canvas of human screams: patterns and acoustic cues in the perceptual categorization of a basic call type.

摘要: Screams occur across taxonomically widespread species, typically in antipredator situations, and are strikingly similar acoustically, but nonhuman primates, they have taken on acoustically varied forms association with more contextually complex functions related to agonistic recruitment. Humans scream an even broader range of contexts, the extent which acoustic variation allows listeners perceive different emotional meanings remains unknown. We investigated how responded 30 diverse human screams six emotion prompts as well selected cues predicted these responses. found that was associated perception emotions from calls. Emotion ratings generally fell along two dimensions: one contrasting perceived anger, frustration, pain surprise happiness, roughly call duration roughness, fear, fundamental frequency. Listeners were likely rate highly matching source context, suggesting some conveyed information about it is noteworthy analysis happiness contexts (n = 11 screams) revealed often yielded higher fear. discuss implications findings for role evolution nonlinguistic vocalizations communication, including consideration expanded diversity calls such might represent a derived function language.
