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.
Meet Fred the Dogfather: A Heartwarming Tale of Adoption as He Embraces Fifteen Orphaned Ducklings Amidst the Mystery of Their Vanishing Mother Duck
In the picturesque setting of Mountfitchet Castle near Stansted, Essex, a heartwarming story unfolds, showcasing the remarkable kindness of Fred, a 15-year-old yellow Labrador. In a twist of fate, Fred has once again assumed the role of a nurturing father figure, this time to a brood of fifteen orphaned ducklings, adding another chapter to his legacy of compassion.
Fred’s story of adopting orphaned ducklings is far from new; in fact, it’s a story that has unfolded not once, not twice, but three times within the past five years. This loyal and gentle labrador retriever has captured the hearts of many with his undeniable knack for stepping up when needed the most.
The tale began in 2018 when Fred first embraced the role of a foster parent, taking in a brood of nine orphaned ducklings. The images and videos of Fred cradling the ducklings on his back, protecting them, and watching over them spread across social media, warming hearts and spreading smiles. His devotion and care were evident as he guided them through their delicate early stages of life.
The following year, in 2019, Fred’s compassionate spirit shone once again. When seven ducklings found themselves abandoned, Fred was quick to extend his paw in support. He welcomed them with open arms, offering a lifeline to these vulnerable creatures and ensuring they had the chance to thrive and grow.
Now, in his senior years at the age of 15, Fred’s story has come full circle. When fifteen more ducklings faced a bewildering loss of their mother, Fred emerged as their steadfast protector and caretaker. Photographs captured the heartwarming scenes of these tiny ducklings nestled between Fred’s legs and perched confidently on his back. The sight of these fluffy yellow bundles finding solace in Fred’s presence is a testament to the remarkable bond that transcends species.
Jeremy Goldsmith, Fred’s owner, shared the touching account, expressing pride in his beloved canine companion’s consistent acts of compassion. While the circumstances surrounding the mother duck’s sudden disappearance remain a mystery, one thing is certain: Fred’s unwavering love and dedication have provided these ducklings with a second chance at life.
Fred’s role as a foster parent isn’t merely about convenience; it’s a testament to the deep empathy and sense of responsibility that he embodies. He is more than a pet – he is a beacon of hope and a reminder that love knows no bounds. As the ducklings continue to grow under Fred’s watchful care, their story stands as a heartening reminder that even in the face of adversity, kindness and love have the power to create a brighter tomorrow.
