Dogs’ brains are sensitive to the familiar high-pitched “cute” voice tone that adult humans, especially women, use to talk to babies, according to a new study.
The research, published recently in the journal Communications Biology, found “exciting similarities” between infant and dog brains during the processing of speech with such a high-pitched tone feature.
Humans tend to speak with a specific speech style characterised by exaggerated prosody, or patterns of stress and intonation in a language, when communicating with individuals having limited language competence.
Such speech has previously been found to be very important for the healthy cognitive, social and language development of children, who are also tuned to such a high-pitched voice.
But researchers, including those from the Eötvös Loránd University in Hungary, hoped to assess whether dog brains are also sensitive to this way of communication.
In the study, conscious family dogs were made to listen to dog, infant and adult-directed speech recorded from 12 women and men in real-life interactions.
As the dogs listened, their brain activities were measured using a functional magnetic resonance imaging (fMRI) scan.
The study found the sound-processing regions of the dogs’ brains responded more to dog- and infant-directed than adult-directed speech.
This marked the first neurological evidence that dog brains are tuned to speech directed specifically at them.
“Studying how dog brains process dog-directed speech is exciting, because it can help us understand how exaggerated prosody contributes to efficient speech processing in a nonhuman species skilled at relying on different speech cues,” explained Anna Gergely, co-first author of the study.
Scientists also found dog- and infant-directed speech sensitivity of dog brains was more pronounced when the speakers were women, and was affected by voice pitch and its variation.
These findings suggest the way we speak to dogs matters, and that their brain is specifically sensitive to the higher-pitched voice tone typical to the female voice.
“Remarkably, the voice tone patterns characterizing women’s dog-directed speech are not typically used in dog-dog communication – our results may thus serve evidence for a neural preference that dogs developed during their domestication,” said Anna Gábor, co-first author of the study.
“Dog brains’ increased sensitivity to dog-directed speech spoken by women specifically may be due to the fact that women more often speak to dogs with exaggerated prosody than men,” Dr Gabor said.
Shelter Canine ‘Best Friends’ Unknowingly Enjoy Last Day Out Together
Living in a shelter can be hard for animals but these two pit bull terriers have managed to make the best out of a bad situation.
Moon Pie and Clipper, both two years old, have been joined at the hip for the past six months in Lifeline Animal Project, an intake shelter for stray dogs in Atlanta, Georgia.
Recently, Connor Abdo, an animal welfare advocate, treated the “best friends” to a day on November 5 and captured all of their fun on camera.
“The shelter is a very stressful environment for the dogs so having a friend is really helpful,” Abdo told Newsweek.
From making friends with strangers to slurping a puppuccino, Abdo said, “they had the best day ever.”
The video was uploaded to Abdo’s dog supply business, @salvation_bark, on TikTok, where shelters receive a donation of half the proceeds.
During the video, the pair can barely contain their excitement as they smile while riding in the back of Abdo’s car. It soon becomes clear that they weren’t shy and are willing to greet everyone they meet.
“They are the definition of you can’t judge a book by its cover. They are both big softies who love kisses, other dogs, and playing,” Abdo said.
However, the video has a bittersweet twist because it’s the final time the tan and white dog, Clipper, will play with Moon Pie, as he has since been adopted.
“It is sad for Moon Pie that his friend is gone but we are confident he will be adopted soon. It is difficult to find an adopter willing to take both dogs though.
“Moon Pie would thrive in any environment. He’d love a dog friend,” Abdo said.
So far, the clip has over 6,000 views and more than 1,000 likes along with plenty of comments.
One user said: “I’m a volunteer and I do this for all the long term dogs at a local shelter. They needed that much needed break from the shelter. So thank you!!!”
Another pointed out: “They seem so well behaved!”
“Such softies who just need love,” said another person.
Another said: “I hope they find forever homes soon.”
Recently, a shelter volunteer showed the reality of living in a shelter for one dog who is yet to be adopted after 1,058 days. But dreams do come true, as proven by Nova, a dog who has finally found a loving family to call her own after more than two years in a shelter.
