The meeting will be held online. Please find a link to the meeting below. Abstract The ability to perceive and respond to emotions expressed in vocalizations is widespread among mammals and plays a central role in social coordination and survival. However, while emotional communication within species is well documented, the mechanisms that enable emotion recognition across species remain poorly understood. Using bonobos (Pan paniscus) as a model within the Hominidae, this research investigates how emotional information is encoded in vocal signals and how it is decoded by both conspecifics and humans. Drawing on recent theoretical advances in cross-species emotion research, this work combines large-scale acoustic analyses with controlled playback experiments. Analyses of natural bonobo vocalizations show that nonlinear acoustic phenomena— a key component of vocal roughness—systematically vary with the caller’s affective state, increasing in emotionally intense contexts. Using parametrically resynthesized calls, causal tests demonstrate that vocal roughness directly influences receivers across species. Exposure to increased amplitude modulation elevates cardiac activity in both bonobos and humans, accelerates orientation responses in bonobos, and leads human listeners to perceive calls as more negative in valence and higher in arousal. These convergent physiological, attentional, and perceptual effects suggest that vocal roughness functions as a cross-species marker of emotional arousal. In parallel, emotional contagion of positive affect was investigated through laughter playbacks. Laughter, a high-arousal, positive-valence signal observed in humans and great apes, elicited play-related behaviors in bonobos. Responses were modulated by familiarity: laughter from familiar conspecifics and human caretakers enhanced positive engagement, whereas responses to unfamiliar individuals varied depending on species. Together, these findings provide evidence for evolutionary continuity in vocal emotion signaling across Hominidae and shed new light on the biological foundations of cross-species socio-emotional communication and empathy.
