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 poor dog is in critical condition and is left outside the hospital like a bag of bones
Ellie was a dog like no other. He had an energy and zest for life that was contagious to all who met him. But it wasn’t always that way. Ellie had a rough start to life that left him in a critical situation in front of a hospital. He was emaciated, just like a bag of bones, and he looked as though he had given up on life.
But then something miraculous happened. One day, a group of animal lovers were passing by and noticed Ellie lying there. They could see he was in a critical condition and decided to take him in. They brought him to a nearby vet, examined him, and determined that he had been severely neglected. He was dehydrated, malnourished, and suffering from a number of health problems.
Despite his difficult condition, Ellie’s spirit was still strong. He was a fighter and refused to give up. The vets and animal lovers who had taken him were amazed at his resilience, and they knew that they had to do everything in their power to help him. Over the next several weeks, Ellie received round-the-clock care from a team of dedicated animal lovers. They fed him small amounts of food every few hours to help him regain his strength, gave him fluids and medicine to treat his health problems, and spent countless hours with him providing him with love and attention that he had never received before.
As Ellie began to recover, his personality began to shine through. He was playful, energetic, and loving. He had a zest for life that was infectious, and everyone who met him fell in love with him. Word began to spread, and people from all over the world began to follow his journey on social media.
Despite his newfound fame, Ellie was quite humble and grateful. He knew that he had been given a second chance at life, and he was determined to make the most of it. He began to work with the local animal rescues to help other dogs in need, and he became an ambassador for animal welfare. As Ellie’s story continued to spread, he became a symbol of hope for animals everywhere. People who had never considered adopting a dog before began to change their mind after hearing his story.
Ellie’s journey is a reminder of the resilience of animals and the transformative power of love and care. It’s a testament to the incredible impact that a group of dedicated individuals can make on the life of a neglected and abused animal. Ellie’s story is an inspiration to us all, and we should strive to be more like him, to be fighters and never give up, to be humble and grateful, and to use our experiences to help others in need.
