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.
A Pup’s Party of One: A Story of a Forgotten Birthday Bash.
In the world of our beloved pets, birthdays hold a special significance. It’s not just another day on the calendar, but rather a momentous occasion when love and affection abound, and tails wag with boundless excitement. Nevertheless, there’s a unique tale of a dog who has realized that sometimes, birthdays can be a lonely affair, even for our four-legged companions
As the sun peeked over the horizon, a small furry friend with a wistful gaze welcomed the day. It was the dog’s special day, one that typically brings merriment, well-wishes, and a delectable cake decorated with glowing candles for humans. However, the dog noticed something peculiar – nobody seemed to remember. The hours ticked by, and the dog’s heart sank deeper into solitude, yearning for a pat on the head or a jubilant chorus of “Happy Birthday.” But alas, the silence remained. As the day progressed, the dog’s mind raced with questions, “Am I not significant? Does no one care?”
The dog’s heart felt heavy due to the absence of well-wishes from family and friends. It did not receive any cheerful phone calls, cards, messages, or even a simple text with a “Happy Birthday” message. As a result, the dog felt unimportant and forgotten. Despite this, the dog found comfort in the presence of its human. The familiar scent and reassuring presence of the person who had always been a source of love and support brought solace to the dog. In the absence of external celebrations, the dog sought joy in simple pleasures such as a gentle pat or a favorite treat.
However, the day lacked the festive atmosphere that is typical of birthdays. There were no balloons, streamers, singing, or laughter. The dog particularly missed having a birthday cake, a symbol of celebration and a treat that signifies a special day for both dogs and humans. The absence of the sweet, fluffy delight left a void in the dog’s heart.
Nevertheless, the dog found comfort in the furry companion by its side. Although equally uninterested in fanfare, the furry friend was content to share the solitude without judgment or disappointment. To this canine companion, the dog was simply a friend, perhaps feeling a little downcast but a friend nonetheless.
As the dog was alone, it began to contemplate the true meaning of birthdays. It realized that it had been placing too much importance on external validation and grand gestures. Birthdays were about more than just celebration; they were about connection, love, and being in each other’s company. The dog came to a realization that it was not unimportant or unloved, but instead valued for the everyday moments spent with its human and furry companion. This newfound appreciation filled the dog with gratitude for the companionship it had, instead of focusing on what it didn’t have on that particular day. As the day came to an end, the dog found comfort in the embrace of its human and the warmth of its furry friend. Although the day was not marked by extravagant celebrations, it was filled with simple togetherness and the profound understanding that significance was not measured by grand gestures, but by the bonds we create and cherish every day. This valuable lesson was learned on a quiet, uncelebrated birthday, shared with those who truly mattered.
