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.
MAN RESCUES POOR ABANDONED PUPPY AND ENRICHES HIM WITH A LOVING FOREVER HOME!
A heartfelt moment, Meets the Person Who Stopped the Pit Bull Puppy’s Death
Even while it might be difficult at times, there are many lovely moments that can only be made possible by the selfless efforts of volunteers.
Joey Wagner, a marine biologist from Nova Scotia in Canada, volunteers at the Baie Ste Marie Animal Society. A pit bull mix dog who had been cruelly mistreated and needed some tender loving care was brought to Joey’s attention in 2013. Joey showed up just as the dog was going to die.
Joey and the rescue crew took the puppy, whose they called Mojo, to Parade Street Vet, PEI Small Animal Hospital for treatment of acute dehydration and demodectic mange. He had totally lost all of his fur and was covered in mite bites by the time he was three months old. As Joey watched, the puppy’s mange was becoming worse as a result of malnutrition and his unhygienic living conditions.
In a Facebook post, Joey said, “When Mojo was surrendered, it was a very short process and a very emotional time.”
As Mojo battled for his life, Joey and his wife Leta fell in love with him. Despite the terrible suffering he had through, Mojo shown a profound ability for compassion and forgiveness. After hearing about his problems, a lot of people asked for his assistance.
As soon as Mojo spotted Joey, his little tail began to wag. Joey writhed his entire body to get closer to his new father, his face covered in kisses. Joey couldn’t help but grin as Mojo thanked him for giving him another opportunity at life.
Joey and Mojo’s joyful reunion has been enjoyed by the globe for more than seven years. Mojo is happy and well-cared for now that he is a member of Joey and Leta’s team. He never entirely grew his fur back, but he doesn’t seem to mind. Since then, the Wagner family has used his tale to inspire others and generate money for animal rescue groups.
The nuanced reaction from Mojo proved that animals possess intellect. Joey had aided Mojo when he was at his most helpless. Their separation is minimal.
