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.
Heartwarming Rescue: Heroic Efforts to Save an Elderly Canine Stranded on an Ice Floe in the Freezing River for Hours
“From Frigid Waters to a Warm Home: Lucy’s Remarkable Rescue and Heartwarming Reunion”
The initial days in a new home can be quite overwhelming for a rescue dog, often leading them to attempt to run away. Such was the case with Lucy, a recently adopted Labradoodle who managed to slip away from her new owner during a walk. Fortunately, locating Lucy didn’t take long, but bringing her back home proved to be a challenging task.
To everyone’s surprise, Lucy ended up stranded on a large piece of ice in the icy waters of the Detroit River. It remains a mystery how she got there, but there she was, clinging to the drifting ice with frigid water flowing around her. The situation was dire, with the risk of hypothermia looming if she remained on the ice much longer. Responding swiftly to the distress call, a team of Wyandotte police officers, firefighters, and animal control officers arrived to lend a hand.
Upon arrival, they found Lucy, trembling and drenched, lying on the ice. Determined to save her, they managed to maneuver the ice chunk closer to the riverbank. A firefighter bravely stood on a slippery, submerged ladder while his colleagues provided essential support by holding onto him with a rope.
“The poor pooch somehow managed to climb onto a chunk of ice but it was drifting away in the river while the dog was freezing,” the police department recounted.
During the daring rescue operation, one firefighter held a ladder against a nearby dock, while another descended it into the freezing water. With the help of a tool called a catchpole, they gently looped it around Lucy’s neck, carefully pulling her towards the ladder. Although the terrified pup had to endure a few seconds in the icy water, the firefighter held her securely in his arms.
Wyandotte Assistant Fire Chief Tom Lyon later described the heartwarming outcome, saying, “It had such a happy outcome. She just had those big brown eyes, and she couldn’t talk, but she probably was just so grateful.”
Lucy was promptly warmed up, and her worried owner was overjoyed to be reunited with her. After a thorough examination by a veterinarian, Lucy received a clean bill of health.
It’s safe to say that Lucy will be spending her days cozily wrapped in a blanket, basking in the warmth of her new home with her loving family.
