They say a dog is a man's best friend, but a new study has found that our pet canines may be more sensitive to the higher-pitched voices of women.
The research team set out to investigate. They trained 19 family dogs consisting of eight different breeds, aged between 2 and 10, to climb into an fMRI machine and lie still long enough for the machine to scan their brains.
While each dog was inside the machine, they listened as the scientists played three different types of pre-recorded human speech: speech directed at dogs, speech directed at human infants, and speech directed at another human adult.Ultimately, the dogs showed greater activity in their auditory cortex when they heard the exaggerated voices we often use for pets or infants. And this was especially true when the speaker was female.
In the brain scans, human voices were processed in a secondary part of the dog's auditory cortex, known as the temporal pole, as well as an area between the temporal lobe and the frontal and parietal lobes called the Sylvian gyrus.
