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.
Stray Pup Brings Traffic to a Standstill on the Pan-American Highway in Quest for Beloved Owner
In a world often characterized by the hustle and bustle of daily life, moments of unexpected compassion and extraordinary encounters remind us of the deep bond that can exist between humans and animals. This is the heartwarming tale of a stray puppy who, in his unwavering quest for his beloved owner, brought traffic to a standstill on the busy Pan-American Highway.
As travelers journeyed along the Pan-American Highway, a vital thoroughfare connecting nations and people, they encountered an extraordinary sight. Amidst the cacophony of vehicles and the rush of commuters, there, in the midst of it all, was a solitary and drenched puppy. He was a picture of adorable determination, standing vigilant and unyielding despite the perilous situation posed by the fast-moving cars.
Good Samaritans, concerned for the welfare of this brave little soul, approached the scene. While their hearts overflowed with compassion, they knew that their medical expertise was limited. Nevertheless, they wasted no time in providing the shivering pup with nourishment and comfort. Despite his ordeal, he appeared to be in relatively good condition.
However, the puppy’s anxiety became palpable when he heard the distant barks of other canines. Fearing for his safety amidst the chaotic traffic, the caretakers made the heart-wrenching decision to isolate him in an unoccupied enclosure. There, in this temporary refuge, the puppy was given a name – Pingan – and began his journey toward recovery and a brighter future.
Pingan, with his infectious spirit, quickly captured the hearts of those who crossed his path. But he bore a physical reminder of past challenges – a missing limb, which required extra care and attention. With regular treatments and unwavering care, Pingan began to thrive. He radiated energy and zest for life.
Perhaps the most heartwarming aspect of this tale is the special bond that blossomed between Pingan and another resident of his newfound sanctuary, a furry friend named Doudou. Doudou seemed to embrace the role of a motherly figure for Pingan, offering him companionship and support as he adjusted to his new life.
Observing Pingan as he settled into his safe and nurturing environment served as a poignant reminder of the profound importance of providing proper care to animals, especially those in need. It reaffirms our duty as compassionate beings to extend a helping hand to those who require it most. Knowing that Pingan now has a warm and secure home, surrounded by love and care, brings immeasurable joy to all who played a part in his journey.
In a world often marked by the relentless march of time and technology, it’s stories like Pingan’s that serve as timeless reminders of the enduring bond between humans and animals. It’s a bond that transcends language, borders, and even the bustling traffic of a major highway, reminding us all of the beauty of compassion and the extraordinary journeys that can unfold when hearts are open to the call of those in need.
