The workshop is dedicated to the exploration of the intricacies of non-verbal communication across species. The meeting, scheduled to take place on October 2024 at Ettore Majorana Foundation and Centre for Scientific Culture, International School of Ethology, Erice, Italy aims to bring together a diverse array of researchers, scholars, and practitioners who share a common interest in unraveling the complexities of communication beyond linguistic boundaries. In particular, the aim is to unveal the nuances of non-verbal communication within and between human dyads, as well as across different species. As evolutionary biologists, you are keenly aware of the pivotal role that communication plays in shaping social dynamics, facilitating cooperation, and driving evolutionary processes. From the subtle gestures and facial expressions exchanged between individuals within a species to the intricate signaling mechanisms employed in interspecies interactions, non-verbal communication serves as a rich tapestry through which behaviors, emotions, and intentions are conveyed and interpreted. The purpose of the present workshop is to give an overview of the "state of the art" of the importance of the ethological approach for the understanding of nonverbal communication between human interactions specifically in clinical therapeutic setting. Given our evolutionary history nonverbal behaviour will be explored in nonhuman primates and in animal- human interactions. This aim will be achieved by interdisciplinary discussion between ethologists, primatologists, child psychologists, psychiatrists and psycotherapists.
