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.
The sign reads, “Unlucky dog – Please help!” as it stands in the middle of a deserted street, catching the eye of anyone who passes by
This was the heartbreaking message left by the puppy’s owner when they abandoned her. The little pup sat forlorn, nestled near a rock, her eyes fixed on the path that the owner had taken, a path from which they would never return to collect her.
A concerned neighbor called Hope For Pets when she stumbled upon the abandoned puppy. Her fear of dogs prevented her from getting too close, and the puppy had been left there since the early morning.
The rescue team interviewed several neighbors, but no one had any information about the puppy. It seemed she had been left behind by a stranger who, out of fear that she might follow them home, had tethered her to a rock.
Physically, the puppy was in good health, but her body reeked, and she was in desperate need of a thorough cleaning.
In a bid to find information about her owner, the rescue team posted pictures of the abandoned puppy on social media with the caption “Unlucky Puppy – Help Me!” The response was overwhelming, with hundreds of people expressing their anger and dismay.
Dogs are known for their unwavering loyalty and companionship, always standing by our side, sharing in our joys and sorrows. There is no justification for labeling them as “Unlucky Dogs” and leaving them to fend for themselves.
Such behavior is not just inappropriate; it’s downright cruel. Hope For Pets continues its search for information about the heartless owner.
If you have any information about the puppy or her owner, please come forward. Justice must prevail, and we hope to identify the person responsible as soon as possible, ensuring that they face the consequences of their actions before the law.
