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.
Sad shelter puppy becomes ecstatic when the firefighter who saved her shows up to adopt her
It’s a heartbreaking reality that some people can abandon their dogs, leaving them to fend for themselves in the harshest conditions. Yet, in the midst of these tales of abandonment and neglect, there are always shining examples of compassion and hope that remind us of the goodness in the world.
The story of Chunkie, a sad shelter puppy, is one such tale that warms the heart and reaffirms our faith in humanity.
Chunkie’s journey began in despair. She was chained and left exposed to the elements, a heartbreaking sight that no dog should ever endure. But fate had other plans for her, and her guardian angel appeared in the form of firefighter Mike Thawley from Sacramento’s Fire Station 14. When he stumbled upon Chunkie, weak, ill, and tied to a post in the pouring rain, he knew he couldn’t simply walk away.
Mike’s first act of kindness was to clean her up and ensure she received the immediate care she so desperately needed. He rushed her to the Front Street Animal Shelter, refusing to abandon her in her time of need.
Upon examination, it became clear that Chunkie had a severe case of mange, and her skin was in a terrible state. However, the dedicated staff at the shelter wasted no time in treating her ailments and providing her with warm clothing to protect her delicate skin. It was evident to everyone that Chunkie was immensely grateful for her newfound safety and care.
But what tugged at the heartstrings even more was the bond that had formed between Chunkie and her rescuer, Mike. Their connection was undeniable, and it was clear that Chunkie had grown fond of the firefighter who had saved her life.
The touching moment of reunion between Chunkie and Mike, captured on camera, melted hearts and brought tears of joy. It was a testament to the deep bond that can develop between humans and animals, forged through acts of kindness and compassion.
In a heartwarming twist to this tale, firefighter Mike Thawley decided to make Chunkie a permanent part of his family. It was a moment of celebration as Chunkie transitioned from a life of despair and uncertainty to one filled with love, care, and companionship.
