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.
An Adorable Journey: A Rescued Pup Finds Meaning and Unwavering Affection as a Surrogate Mom to Three Precious Kittens
Introducing Georgia, a courageous and tenacious shepherd mix who embarked on a challenging journey filled with both heartache and triumph. Initially found at a remote gas station, Georgia’s future appeared uncertain. But fate took an unexpected turn when her pregnancy was discovered, offering her a fresh start, albeit with its own set of hurdles.
Following her rescue, Georgia, a petite shepherd mix, received a thorough veterinary examination that revealed her impending motherhood, with the puppies expected in about a month. As days passed, Georgia acclimated to her new environment, basking in the freedom and comfort of a welcoming backyard.
Her excitement peaked on the fifteenth day as she eagerly explored her whelping pool. However, tragedy struck on the twenty-fifth day when she went into premature labor. The puppies, too tiny to latch, faced vulnerability and struggled to survive. Two of Georgia’s pups sadly didn’t make it past birth. In a desperate bid to save Georgia’s life, an emergency C-section and spaying were performed.
While Georgia physically recuperated from the ordeal, emotional scars lingered as she yearned for her lost babies. In an effort to offer her comfort and purpose, three motherless newborn kittens were introduced to her on the twenty-seventh day. Despite her grief, Georgia’s nurturing instincts kicked in, and she wholeheartedly embraced the kittens as her own. Even though not all the kittens could latch, Georgia diligently cared for them, bottle-feeding them until they could thrive independently.
Regrettably, one of the kittens passed away, leaving two healthy and thriving babies, named Graffiti and Gumball. Georgia’s dedication to her surviving offspring remained steadfast, providing them with the love and care they needed to flourish. Day by day, the bond between Georgia and her kittens grew stronger, and they found solace and contentment in each other’s presence.
On the thirty-second day, Georgia proudly christened her babies—Graffiti, Gumball, and the newest addition, Goober. The little family flourished, with the kittens opening their eyes, gaining weight, and reveling in the love and protection of their devoted mother.
However, on the forty-fifth day, a new challenge arose as Georgia developed a visible tumor. This brave shepherd mix was about to embark on a journey of cancer treatment and recovery, temporarily separating her from her beloved kittens. Despite this setback, Georgia’s prognosis was positive, and a full recovery was anticipated.
Day 50 marked a new chapter for Georgia as she transitioned to her adoptive home under the name Milo. Her new dad, @torbazorb14, provided her with love, care, and unwavering support throughout her cancer treatment. Day by day, Georgia’s strength and resilience shone through, and on day 70, she completed her final chemo treatment. This resilient little lady, who had endured abandonment, loss, and medical challenges, emerged victorious.
As Georgia continued her recovery, her kittens rapidly grew. They reached a healthy weight of 2.5 pounds and reveled in newfound confidence. While the author, a self-proclaimed dog person, acknowledged missing the mischievous kittens, they celebrated the happy endings awaiting them.
On day 95, a long-awaited reunion unfolded between Georgia (now Milo) and her kitten Gumball, now known as Toby. However, reality didn’t quite align with fairy-tale expectations. Milo displayed a hint of fear, serving as a reminder that animals express their emotions honestly. Nevertheless, it marked a genuine and joyous ending for Milo and Toby.
