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.
“Unwavering Loyalty: The Heartwarming Tale of Puppies Mourning Their Mother on the Railroad Tracks”
Near an abandoned railway, a group of unfortunate puppies managed to survive and make a modest living. One of the puppies stood out as exceptional, displaying unwavering loyalty to its mother. Sadly, the mother, an elderly dog, met a heart-wrenching fate after being struck by a passing train on the very railway track they called home.
Every day, this devoted puppy would come back to the railway, tirelessly searching the area for its mother. Unaware of her untimely demise and unable to comprehend her absence, the pup would discover a dry leaf, hop onto it, and with tender touches, lick away its own tears, as if silently imploring its mother to come back. This heart-wrenching routine persisted for several days until destiny intervened. A young girl stumbled upon the railway and bore witness to this poignant scene. Moved by an overwhelming surge of empathy, she felt an irresistible urge to assist these vulnerable puppies
She showed kindness by carrying a basket filled with cookies and drinks, and even extended it to the unique puppy. The one-of-a-kind puppy eagerly hopped onto the basket and enjoyed the provided nourishment. However, an underlying feeling of longing lingered as it repeatedly returned to the railway, settling on the dry leaf, seemingly forever in quest of its lost mother.
The touching story deeply moved the young woman, causing tears to well up in her eyes. Touched by the puppy’s heart-wrenching situation, she made a heartfelt decision. She would take this special pup under her wing, providing it with the warmth, shelter, and nurturing it so desperately required. From that point on, the unique pup found a new refuge, a fresh family, and a renewed opportunity for happiness. This story serves as a poignant reminder that love and care possess an extraordinary transformative power, capable of guiding us through even the most challenging of circumstances and illuminating our path with hope and resilience.
