Adult human perception of distress in the cries of bonobo, chimpanzee, and human infants

Understanding the extent to which humans perceive the emotional state of animals has both theoretical and practical implications. While recent studies indicate that natural selection has led to some convergence of emotion coding among vertebrate species (i ...

No need to shout: Effect of signal loudness on sibling communication in barn owls

Hervé Lissek, Xavier Falourd, Patrick Marmaroli, Dorian Cazau

In animal communication, signal loudness is often ignored and seldom measured. We used a playback experiment to examine the role of vocal loudness (i.e., sound pressure level) in sibling to sibling communication of nestling barn owls Tyto alba. In this spe ...

Gaze Responsive Visual Comfort: New Findings On Gaze Behaviour In A Daylit Office Space In Relation To Glare

Marilyne Andersen, Jan Wienold, Mandana Sarey Khanie

Using a newly developed gaze-driven methodology for discomfort glare assessments, we studied gaze behaviour in different glare conditions. The study was done in a series of experiments where gaze behaviour of the participants were recorded using eye-tracki ...

Perception of Social Cues of Danger in Autism Spectrum Disorders

Nouchine Hadjikhani, Loyse Hippolyte, Ophélie Rogier, Torsten Ruest, Britt Russo

Intuitive grasping of the meaning of subtle social cues is particularly affected in autism spectrum disorders (ASD). Despite their relevance in social communication, the effect of averted gaze in fearful faces in conveying a signal of environmental threat ...

Relatedness influences signal reliability in evolving robots

Dario Floreano, Laurent Keller, Sara Mitri

Communication is an indispensable component of animal societies, yet many open questions remain regarding the factors affecting the evolution and reliability of signalling systems. A potentially important factor is the level of genetic relatedness between ...

The evolution of communication in robot societies

Sara Mitri

Communication is fundamental to life on earth. All social organisms, from bacteria to humans, use communicative signals to coordinate their behaviors with members of their own and other species. Despite its key role in social organization, many questions r ...

Pointing with the eyes: The role of gaze in communicating danger

Nouchine Hadjikhani

Facial expression and direction of gaze are two important sources of social information, and what message each conveys may ultimately depend on how the respective information interacts in the eye of the perceiver. Direct gaze signals an interaction with th ...

Evolutionary Conditions for the Emergence of Communication in Robots

Dario Floreano, Stéphane Magnenat, Laurent Keller, Sara Mitri

Information transfer plays a central role in the biology of most organisms, particularly social species [1, 2]. Although the neurophysiological processes by which signals are produced, conducted, perceived, and interpreted are well understood, the conditio ...
