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.
Chinese authorities crack down on stray dogs after a Rottweiler mauls a toddler
A shocking video of a Rottweiler mauling a two-year-old girl in China has prompted a crackdown by local authorities on stray dogs that some argue has now gone too far.
Authorities were initially praised for their swift response to the incident, but netizens soon began sharing accounts of stray canines in their neighborhood being roughly rounded up and, in some cases, put down.
The new directive to clamp down on large, unleashed dogs is being cited as the latest example of a knee-jerk reaction by Chinese authorities that also highlights the country’s long-standing struggle with animal rights and welfare.
“Just because a large dog bit a child, all of them are being hunted down by ruthless security guards and police,” one user wrote on Chinese social media Weibo under the hashtag “Will the biting of the girl bring stigma to a large dog?” viewed by almost 1 million users.
“Such a one-size-fits-all approach makes me really sad,” she said.
Video of the October 16 attack shows the girl stepping out of a residential compound with her mother in Chongzhou, in China’s southwestern province of Sichuan, and immediately being chased and bitten by a large black Rottweiler.
The mother tries to shield her daughter from the dog, but then tries to pull her back as the animal drags the child around.
A cleaner who comes to help with a broom also fails to drive the dog away.
A man finally succeeds in chasing the Rottweiler away with a wooden stick.
By that time, the mother is sitting on the ground, crying, with her daughter in her arms.
Calls to add Rottweilers to list of banned dogs after string of attacks
The toddler was admitted to hospital, where she was treated for a ruptured kidney, fractured ribs and bite marks on various parts of her body, several Chinese state media outlets reported.
Authorities caught the Rottweiler and detained its owner, according to state media.
Since then, local authorities in a raft of provinces including Shandong, Jiangxi, Yunnan, Hunan, Anhui have stepped up law enforcement, some more heavy-handed than others.
Stray dogs are the main targets, but pets who are unleashed can also be subject to control measures.
Most local police said they would ramp up patrols to round up stray dogs and fine owners who fail to put their dogs on a leash.
More robust approaches include police in Yanzhou in Shandong vowing to hunt down “mad dogs” and euthanize them.
The country is home to 40 million stray dogs, according to the 2021 China Pet Industry white paper.
In the past, strays have been blamed for rabies outbreaks and authorities have attempted to control their numbers with culls.
In one case that triggered an outpouring of grief online, a small stray dog – known as Xiao Huang, or little yellow – was taken away in a net by security personnel at a university campus in Chongqing and beaten to death, according to state-affiliated media.
Many netizens were perplexed by the decision to kill a tiny dog, whose image is being shared on Weibo with the hashtag “straydogxiaohuang,” with a call for greater rights for stray dogs.
The university said the canine had entered the student dormitory, posing a threat to the safety, according to state-affiliated news outlet Beijing Time.
In Shanghai, images of police officers descending on a local neighborhood and dragging away a German Shepherd also sparked fury online.
Many netizens believe the dog was old and did not pose a danger to the community.
But Shanghai authorities said they were acting on complaints from neighbors about an aggressive dog and that it was “taken in and dealt with,” according to a post on their WeChat account.
This is not the first time Chinese authorities have been accused of being heavy-handed with animals.
During Covid, some pet owners complained that their dogs were beaten to death when they were taken away for quarantine, anecdotes that sparked uproar across the internet.
A number of netizens praised the authorities for taking proactive steps, but most warned against the consequences of going overboard.
Celebrities also joined the chorus of animal lovers to call for better understanding.
Chinese actress and singer Cya Liu, who won Best Actress at the Hong Kong Film Awards last year, called for an end to the killing.
“Not all stray dogs are bad just as not all men are good,” she wrote on Weibo, with the hashtag “voicing out for stray dogs.”
Bo Ai Animal Protection Centre Of Guangyuan in Sichuan wrote on Tumblr-like Chinese social media Meipian that China should be using its development to instill a better sense of social responsibility and a respect for animals in people.
“Beating and catching dogs at every turn. Let the world see what our great motherland is like,” it said.
