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.
“15 Years Later: A Heartwarming Moment as a Dog Celebrates its First Birthday with a Cake and a Tear of Joy”
The aging dog had been a loyal companion to its owner for 15 years and a significant part of their life. The owner wanted to show gratitude for the dog’s unwavering companionship and decided to throw it a memorable birthday party. The party preparations were filled with anticipation and thrill, as the owner carefully selected decorations such as colorful balloons and streamers to create a joyful ambiance. A large banner flaunted on the wall, proudly announcing “Happy Birthday to our beloved companion!”
With a wildly wagging tail, the dog watched in pure joy and excitement as the celebration in honor of its existence unfolded. It was beyond thrilled that its owner had invited close friends and relatives who had witnessed its unwavering loyalty and attachment to its human over the years.
The scent of delicious snacks wafted through the air, tempting both the guests and the furry friend in attendance. The host had gone above and beyond to offer an array of tasty treats that catered to both human and canine taste buds. Plates were piled high with mouth-watering food, and a one-of-a-kind dog cake stole the show, complete with crunchy biscuits and a single candle.
As the time came to cut the cake, cheers and well-wishes filled the room. Surrounded by loved ones, the dog soaked up the warmth of the attention showered upon it. With a gentle paw, the pup even helped guide the knife, playing an active role in this special moment. The cake was divided and enjoyed, a thoughtful gesture symbolizing the bond between the dog and its human companions.
Throughout the day, the pooch relished the love and affection lavished upon it. It was treated to affectionate cuddles, indulgent tummy rubs, and heartfelt expressions of gratitude. The dog was filled with a deep sense of satisfaction, aware that its mere presence had made a difference in the lives of those around it, just as they had left an indelible mark on its own being.
The festivities carried on throughout the night, with fun and entertaining activities that brought smiles and happiness to all those in attendance. Despite being older and moving at a slower pace, the dog fully immersed itself in the festivities, cherishing every moment with pure joy. It seemed as though all of its troubles and worries had vanished, replaced with an overwhelming feeling of contentment and belonging.
As the party drew to a close, the dog cozied up next to its owner’s feet, overwhelmed with a profound sense of pleasure and adoration. Tears of happiness sparkled in its eyes, a testament to the depth of its emotions. This was a moment 15 years in the making, a celebration of its very existence, and one that would forever be etched in its memory.
In the end, it turned out to be more than just a regular birthday celebration. It was an occasion to commemorate the unwavering love that a dog has for its owner. It was a tribute to the enduring affection, loyalty, and happiness that a beloved pet brings into our lives. Moreover, it served as a gentle reminder to the elderly dog that it was still valued and that its journey had been exceptional.
As the night drew in, the dog drifted off to sleep, wrapped in a cocoon of love and gratitude. In its slumber, it relived the day’s events, the laughter, and the shared moments of joy. A smile crept onto its snout as it realized that it had borne witness to a remarkable milestone: a birthday bash that celebrated a lifetime of cherished memories.
