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.
A Heart-Wrenching Ordeal: A Dog’s Suffering, Chained, Malnourished, and Thirsty on a Balcony
Owning a pet is a significant commitment that entails a substantial responsibility for their safety and well-being. These living beings are entirely reliant on their owners for care and protection.
Recently, concerned citizens stumbled upon a heart-wrenching scene, where a dog dangled precariously from a balcony, teetering on the brink of tragedy. Fortunately, a swift rescue mission prevented any harm from befalling the desperate canine.
What they encountered on that balcony, however, shocked them more profoundly than the impending disaster itself. The dog, a German Shepherd, was discovered alone on the balcony of an apartment in Egypt. What added to the distressing scenario was the revelation that the dog had endured days of being tethered to the balcony without access to food or water. It appeared famished, and its leap from the balcony seemed to be a final, desperate bid to escape the deplorable conditions.
Regrettably, a chain bound the dog’s neck, rendering it incapable of freeing itself. The poor animal was left hanging over the balcony, choking and helpless. Even if not for the chain, the height of the balcony, three stories above the ground, would have posed a grave risk to the dog.
Miraculously, a man heard the anguished cries of the German Shepherd and rushed to its aid. Another neighbor had already attempted a rescue but had been unsuccessful. With the newcomer’s assistance, they managed to retrieve the dog back onto the balcony.
It was evident that the chain had inflicted severe lacerations on the dog’s neck, although, fortunately, they were not life-threatening. The living conditions on the balcony were nothing short of deplorable, with the dog confined amidst its filth, deprived of both sustenance and hydration.
The dog, with lacerations on its neck from the constricting chain, was subsequently transported to the Egyptian Society for Mercy to Animals shelter. Here, it received the necessary medical attention for its injuries and underwent treatment for any illnesses or ailments it may have acquired during its harrowing confinement. Skilled veterinarians successfully mended the lacerations and administered the care needed for a full recovery.
After a few weeks of treatment, the German Shepherd, now named Bella, was transferred to the Special Needs Animal Rescue & Rehabilitation shelter. From there, she embarked on a journey to the United States, where a loving family had eagerly adopted her. Showered with the love and compassion she deserved, Bella could finally heal from the trauma of her past life in the grim balcony confinement.
Bella made a remarkable recovery and found contentment with her new family. She became a cherished companion to her new guardians and an integral part of their household, leaving behind the horrors of her previous existence on that unforgiving balcony.
