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.
100-year-old woman finds ‘perfect match’ in 11-year-old senior chihuahua
Life has a beautiful way of surprising us, and sometimes, those surprises come in the form of a furry, four-legged companion. Meet Johanna Carrington, a remarkable centenarian who, despite a life filled with challenges, has always carried a deep love for dogs.
Johanna’s journey began in war-torn Germany, where owning a dog was a distant dream. She and her late husband once shared their home with eight Pekingese dogs, a testament to their shared love for these loyal creatures. However, when her beloved dog Rocky passed away, Johanna was left feeling alone in her house, yearning for a furry friend.
One might think that, at the age of 100, adopting another dog could be a challenge. Johanna was uncertain if the shelter would allow someone of her age to adopt. Fortunately, a caring neighbor who supports Muttville Senior Dog Rescue in San Francisco suggested that this organization might have the perfect solution.
Muttville Senior Dog Rescue recognized that Johanna Carrington and a senior dog would be an ideal match. After careful consideration, Johanna adopted Gnocchi, a charming 11-year-old Chihuahua, whom she lovingly renamed Gucci.
Gucci’s life had a rocky start; he was rescued from a hoarding situation where his previous owner had 22 dogs. Being the only pampered pooch in his new home brought him immense joy. Johanna’s caregiver, Eddie Martinez, and her daughter, Debbie Carrington, made a heartfelt commitment to ensure that Gucci’s golden years would be filled with love and care.
The moment Gucci entered his new home, he seemed to recognize that he belonged there. Johanna recalled the heartwarming first encounter, saying, “He approached the home as though he’d been here before. It was incredible. When he spotted me seated in my chair, he leapt up and perched on my lap. He made himself extremely at ease. Right away, he was just our kid.”
Now, Gucci enjoys a life fit for a pampered pup. He has “oodles and oodles” of toys to play fetch with, daily back massages while watching TV with his new mom, and even the privilege of burrowing under the covers in bed for extra comfort.
Debbie Carrington, Johanna’s daughter, shared how Gucci’s arrival transformed their home, saying, “It was sort of sad here after she lost her other dog. It was silent and melancholy until Gucci came in and brought excitement into the house. Laughing at him running around and doing silly things, and then him resting on her lap with her when she’s in her chair or bed, it’s just making her very happy.”
The heartwarming bond between Johanna and Gucci is a testament to the joy and companionship that animals bring into our lives, regardless of age. In fact, scientific research supports the positive impact of pet ownership on emotional and social well-being, particularly in older individuals.
As Johanna approaches her 101st birthday in December, she and Gucci plan to celebrate this special milestone together. For Johanna, dogs have played a significant role in her long and healthy life, proving that the love between a human and their furry friend knows no age limits.
In a world that often seems fast-paced and hectic, the story of Johanna and Gucci reminds us of the simple yet profound happiness that animals can bring into our homes and hearts.
