“Say Wilbur, get a load of this story.” If you grew up in the '60s, you probably recognize the voice of Mr. Ed, TV’s talking horse. And it turns out, he might recognize your voice, too. A new study shows that even non-talking horses can tell individual people apart based on the sound of their voice.
Researchers put 32 horses in front of a familiar trainer and a new person. When the horses heard their trainer’s voice coming from a
loudspeaker1, they looked at their trainer almost
exclusively2. When the stranger’s voice was heard, they were about
equally3 likely to look at either person.
Another test used 10 trainers the horses were familiar with. And when the animals heard a voice, they looked at the correct person faster and
concentrated4 on that person much more than any of the other choices. The study appears in the
Proceedings5 of the Royal Society B.
Researchers think the ability to recognize individual handlers might be rooted in the relationships the steeds have with their conspecific NEIGHHHHbors. I mean, neighbors.
Thanks for the minute for Scientific American 60 second Science, I am Amy Kraft.
