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.
”Is He Ok?” Tom Hanks Shocks Fans in New Look — Fans Are Worried
Tom Hanks and his wife, Rita Wilson, once again proved that they are one of Hollywood’s most iconic and solid couples as they attended a gala in Beverly Hills. Hanks radiated charm and Hollywood glamour, but it was a significant transformation in his look that drew a lot of attention.
The Women’s Cancer Research Fund hosted its prominent annual fundraiser, “An Unforgettable Evening,” at the Beverly Wilshire in Beverly Hills.
Among the many celebrities who added their star power to the event were Tom Hanks, 67, and his wife, Rita Wilson, 67, who serve as honorary chairs.
Upon their arrival, the Forrest Gump actor commanded attention before the cameras, accompanied by his wife. He donned an impeccable black ensemble, featuring a crisp white shirt, a striking, black-patterned tie, and coordinating shoes.
Wilson stood beside her husband in a vibrant pinkish-red dress, featuring an off-the-shoulder design and a cinched waist.
Hanks showcased a fresh, short haircut, highlighting his salt-and-pepper hair, but what truly caught everyone’s attention was his mustache—a rare and striking look for him.
But many fans were worried about the star and thought that he didn’t look in the best shape. One person wondered, “Is he OK???” Another observed, “Tom looks a little beat up.” Someone else added, “He’s almost unrecognizable…she must be concerned!”
Another Hollywood icon generating buzz with his new appearance is Tom Cruise. Earlier this year, the star attended a gala event in London, where his look caused quite a stir.
