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.
A lot of people had a crush on her in the 1980s, but look at her now…
After her breakout role in “Crocodile Dundee”, Linda Kozlowski found herself thrust into the international spotlight. Starring opposite Paul Hogan, the film marked a significant milestone in her career trajectory. However, following the “Dundee” series and a handful of other projects, Kozlowski gradually veered away from the glitz and glamor of Hollywood.
Hailing from Fairfield, Connecticut, Linda Kozlowski was born on January 7, 1958, with aspirations of treading the boards. She pursued her passion for acting by enrolling in the prestigious theater program at the Juilliard School. Upon graduating in 1981, she made her mark in various off-Broadway productions before transitioning to minor roles on Broadway and television. Notably, she starred alongside Dustin Hoffman in the television movie “Death of a Salesman”, marking a significant milestone in her career.
Linda’s path to fame wasn’t without its hurdles. Following her stint as a waitress post-“Death of a Salesman”, she relocated to California. It was there, under the wing of her mentor Dustin Hoffman and his wife, that Linda found refuge in their Malibu beach house. It was from this humble abode that Linda embarked on an audition that would alter the course of her life.
Dustin Hoffman’s endorsement landed Linda the coveted role of Sue Charlton in “Crocodile Dundee”, a character she portrayed with aplomb. The film’s astronomical success, raking in over $320 million against a $10 million budget, catapulted Linda Kozlowski into stardom virtually overnight. Interestingly, her fame initially soared in Australia due to the film’s early release there.
Despite her newfound celebrity status, Linda felt somewhat overlooked in Hollywood. While she reprised her role in the “Crocodile Dundee” sequels, she declined numerous offers for roles that pigeonholed her as the quintessential girlfriend of a comedic lead. Ultimately, Linda decided to bid adieu to acting after the third installment of “Dundee”.
In her personal life, Linda Kozlowski found love on set with her co-star Paul Hogan during the “Crocodile Dundee” series. They tied the knot in 1990 and welcomed their son, Chance, in 1998. However, their marriage dissolved in 2014. Following her divorce from Paul Hogan, Linda received a substantial settlement, empowering her to chart her own course. She turned her gaze towards Morocco, where she crossed paths with Moulay Hafid Baba, a native tour guide, sparking a profound life transformation.
Together, Linda and Moulay Hafid Baba founded the luxury travel agency Dream My Destiny in Marrakech. Crafting bespoke travel experiences tailored to their clients’ desires became their passion. Linda seamlessly transitioned from the glitz of Hollywood to the enchanting vistas of Morocco.
While Linda Kozlowski may have bid farewell to the silver screen, her legacy as Sue Charlton in “Crocodile Dundee” endures. At 63, she embraces her adventurous spirit and finds fulfillment in her new life in Morocco. She believes that reality surpasses fiction, channeling her intuition honed during her acting career into curating unforgettable experiences for travelers around the globe.
