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 moment the heroic rescue team valiantly battled against the clock to liberate the unfortunate dog trapped in the underground bunker left everyone overwhelmed with emotions
In a heart-pounding rescue operation, a dedicated team of heroes faced a race against time to free Ziggy, a 10-year-old Patterdale terrier, from a perilous underground bunker. This harrowing ordeal left everyone on edge as they fought tirelessly to save a beloved pup trapped in a dire situation.
Ziggy had been enjoying a carefree day on his family’s farm, frolicking alongside his mom when an unexpected turn of events sent him spiraling into a dark abyss—an underground drain pipe. At first, his mom wasn’t overly concerned; after all, this wasn’t Ziggy’s first escapade into subterranean exploration. But as the minutes turned into hours, and Ziggy failed to reappear, panic set in.
Lauren Flintoft, Ziggy’s mom, shared her worry, saying, “I was worried he might have been stuck, and that’s why he didn’t appear. My husband Tim spent the whole night trying to entice him out, and when he didn’t emerge, I called in help.”
Desperate for aid, Flintoft reached out to the RSPCA (Royal Society for the Prevention of Cruelty to Animals) with hopes that they could assist in rescuing Ziggy from his precarious predicament. A team of dedicated rescuers promptly arrived at the scene, ready to tackle the daunting task of locating and liberating the trapped terrier.
The operation was not for the faint of heart. Rescuers had to meticulously map the complex underground pipes, meticulously plotting their course to reach Ziggy. With unwavering determination, they began to dig two enormous holes, strategically positioned to expose Ziggy’s location.
Finally, after hours of relentless effort, the group spotted a glimmer of hope—a glimpse of Ziggy’s furry form within the confined space. With great care and precision, they gently cleared away the debris that held Ziggy captive, allowing him to wiggle his way to freedom. Remarkably, Ziggy had endured an astonishing 19 hours trapped in the drain pipe.
Despite his extended ordeal, Ziggy emerged from his subterranean prison unharmed, albeit a bit shaken. He was swiftly reunited with his relieved family, basking in the warmth of their embrace. This heartwarming rescue reaffirmed the unwavering bond between humans and their faithful canine companions.
Faebian Vann, an animal collection officer with the RSPCA, joyfully shared, “He’s now back home with his owners where he belongs, and no doubt he’ll be getting up to no good again very soon.”
Ziggy’s triumphant return serves as a testament to the extraordinary efforts of a dedicated rescue team and the power of compassion in the face of adversity. His story reminds us of the enduring spirit of our four-legged friends and the lengths we’re willing to go to ensure their safety and well-being.
