Humans identify emotions in the voices of all air-breathing vertebrates

Amphibians, reptiles, mammals – all of them communicate via acoustic signals. And humans are able to assess the emotional value of these signals. This has been shown in a new study conducted by researchers at Vrije Universiteit Brussel and Ruhr-Universität Bochum, in collaboration with colleagues from Alberta, Canada, and Vienna, Austria, in the journal “Proceedings of the Royal Society B”. The team was headed Dr Piera Filippi.
