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.
Mother Dog Attempts to Care for Four Tiny Pups Despite Being Left by Owner and Having Both Legs Crushed by a Train
It’s impossible not to weep when you see the tragic predicament of abandoned stray dogs. However, not every mother dog is as courageous, tough, and protective of her children as Si Bao.
After being “mercilessly abandoned” by its owner, this dog was engaged in a tragic accident in which her hind legs were crushed by a train. Si Bao’s life appeared dismal until she gave birth to four very gorgeous and healthy pups, who practically became the driving force in this miserable mother dog’s existence.
After recovering the pleasure of living in life after having children, Si Bao restored her spirit and always kept a resilient and strong attitude to take care of her children. Si Bao walked on two front legs, keeping a watchful eye on the children.
Si Bao’s luck continued to smile when the Jill Robinson-founded nonprofit Animals Asia rescued his family and made this heroic mother dog an animal ambassador. As a consequence, Si Bao has been transferred to the organization’s headquarters, where he may begin a new life with his kid rather than struggling to earn a livelihood off the scraps of food that travelers throw away at the train track. His sole surviving is Muddie.
Furthermore, Si Bao has been renamed Lelly, and she is planning to install wheeled prosthetic legs to allow her to move more freely. Three of Lelly’s four pups died of high fever when the organization found them, leaving just Muddie.
Lelly is currently living the good life as a “Asia animal” ambassador for Animals.
Even though she is just a little dog, Lelly exemplifies an unbreakable character that does not give in to hardship.
