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.
When we noticed the ailing dog pleading with onlookers for assistance with the massive tumor that was causing him such agony that he had to collapse, we became very alarmed
Meet Mixi, a brave dog who had been suffering from a massive tumor under his chest for a long time. The tumor was so large that it hung down and touched the ground when he moved, causing him immense discomfort. Desperate for help, Mixi went near a car, hoping to find someone who could assist him.
Fortunately, kind-hearted individuals came to his rescue and took him to a veterinary hospital to receive treatment. The pictures taken before the surgery showed the extent of the tumor, which was heavy and had broken through the skin, leaving a gaping hole. But thanks to the successful surgery, the tumor was completely removed, giving Mixi a new lease on life.
After the surgery, Mixi was brought back to his home, where he eagerly awaited the arrival of his owner, a woman wearing a blue shirt. He seemed to have a lot to say to her, and his excitement was palpable. His owner was emotional and grateful to the people who had saved her beloved dog’s life. She expressed her heartfelt thanks and appreciation for giving Mixi a chance at a happy and healthy life.
Despite still needing care and medication for the healing process, Mixi’s owner was hopeful that he would fully recover and not have any further health issues. She shared her story, describing the pitiful state Mixi was in before the surgery and how she had feared that he might not survive. However, she now believed in miracles as she saw Mixi’s remarkable progress.
Mixi’s owner expressed her deep gratitude to the kind-hearted individuals who had helped her dog and gave him a second chance. She thanked them from the bottom of her heart and looked forward to a brighter future with Mixi by her side, now able to run freely and enjoy life to the fullest.
Mixi’s story is a heartwarming reminder of the incredible resilience and strength of animals and the transformative power of compassion and care. It is a testament to the dedication of veterinary professionals and the kindness of strangers who stepped forward to help an innocent animal in need. With a bright future ahead of him, Mixi’s journey is a true testament to the unwavering bond between humans and their furry companions, and a story of hope and healing that will inspire many.
