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.
Guide Dogs of America Needs Volunteer ‘Puppy Raisers’
Working with wonderful woofers, the sort of furry joy-bringers that make a difference in people’s lives?
Pitching in with a pack of incredible pups can make a lasting impression on a person’s mind, outlook, and, for sure, their spirit, too.
And that chance to lend a hand, your time, some empathy and understanding, and a whole lot of love is coming up, on Dec. 11, thanks to a “puppy raiser” training session with Guide Dogs of America.
This is a virtual happening, via Zoom, and it will be the final online information event before in-person gatherings return to the Sylmar campus in 2022.
Guide Dogs of American pairs trained pups with “… individuals who are blind/visually impaired and service dogs for veterans and children with autism,” with dogs also being placed in “hospitals, schools, and courtrooms.”
“Our highly skilled canines become trusted companions that increase people’s confidence, mobility, and independence. All programs and services, including transportation, personalized training, room/board, and postgraduate support, are provided at no cost to the recipient,” states the organization on its site.
And helping the organization achieve its mission?
Puppy raisers, those dedicated volunteers who are among some of the first people a young, in-training dog gets to know, trust, and adore.
If you choose to pursue volunteering for this life-changing role, there’ll be a few initial considerations, as well as matters you’ll want to mull.
One consideration? Where you reside. You and the puppy in your care will need to call upon the Sylmar campus on occasion, and attendance at both monthly puppy group meetings and “puppy kindergarten classes” is required.
The Dec. 11 information session will address what you can expect from meetings and classes, as well as what at-home life will be like with the future guide dog you’re helping to raise.
Questions covered include the breeds and types of puppies that volunteers raise, what can be expected in terms of puppy proofing and such, what out-of-pocket expenses might look like, and how long the puppy will live in your home.
And, yes: “(W)hat happens when the dogs ‘go off to college’ to begin formal training” is also a central topic of the session, as well as how dogs are paired with their forever people once they’ve graduated.
The word straight from Sylmar? “We ALWAYS need puppy raisers,” says Stephanie Colman, the coordinator of the puppy program.
So even if you can’t join the December Zoom, you can plan to attend an in-person information session on the Guide Dogs of America campus, in early 2022.
Could this be your new year’s resolution?
