(Phys.org) —People interpret their dogs’ sounds by how long or short is the bark and also by how high or low the pitch.
Moreover, humans rely on the same rules to assess emotional valence and intensity in conspecific and dog vocalizations. These are the findings of six researchers from Eotvos Lorand University, and the Hungarian Academy of Sciences in Budapest. Tamás Faragó, Attila Andics, Viktor Devecseri, Anna Kis, Márta Gácsi and Ádám Miklósi said shorter barks sound more positive and high-pitched noises seem more intense to humans.
If those measures sound familiar, that is because people use the same rules to work out how their dog is feeling as they do to determine the emotional state of other humans.
“Our findings demonstrate that humans rate conspecific emotional vocalizations along basic acoustic rules, and that they apply similar rules when processing dog vocal expressions.”
