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.
Brave Mother Dog Jumps and Sacrifices Her Life To Protect Her Poor Cubs Under A Falling Tree
When it comes to the power of motherly love, no one can deny the extent to which a mother will go to protect her progeny. This is notably true in the animal kingdom, where maternal instincts are essential for survival. One such instance of this can be seen in the narrative of a mother dog who sacrificed herself to save her offspring in front of a fallen tree.
In this endearing tale, a mother dog and her young puppy were out for a walk when they came across a fallen tree obstructing their path. The infant was too small to clamber over the tree, and the mother dog knew that she had to find a means to assist her little one. With no other options available, the mother dog made the ultimate sacrifice and settled down on the ground, creating a makeshift bridge for her puppy to traverse over the tree.
As the infant made its way across the mother’s back, the weight of the little one proved to be too much for the mother dog, and she was unable to get back up. Despite her immense agony and discomfort, the mother dog remained in the same position until assistance arrived. Her altruistic act of love had saved her puppy’s life, but it had come at a tremendous cost to her own.
This tale is a testament to the power of motherly love and the extraordinary extent that a mother will go to protect her young. It is a reminder that love knows no bounds and that the bond between a mother and her child is unbreakable. The mother dog’s sacrifice is a genuine example of the unconditional love that exists between a mother and her progeny.
At its essence, this narrative is about selflessness and sacrifice. It is a reminder that true love means placing the requirements of others before your own. The mother dog could have easily left her puppy behind and continued on her way, but she knew that her child’s safety was more essential than her own. It is this kind of selflessness that makes the bond between a mother and her child so special.
The power of motherly love can be seen throughout the animal kingdom, from canines to lions to birds. It is a force that is genuinely awe-inspiring and has the ability to move even the hardest of souls. This story of the mother dog and her puppy is just one example of the myriad acts of love that take place in the animal kingdom every day.
