Study reveals dog response to human speech

A recent study from the Department of Ethology at Eötvös Loránd University has revealed new insights into how dogs react to human speech, particularly when it is spoken in a high-pitched tone often used when addressing infants. The findings were published in the journal Communications Biology and indicate that dogs' brains show increased activity when exposed to this specific tone of voice, known as "baby talk."

Definition of baby talk

Baby talk refers to the softer, more melodic speech adults use when interacting with infants and young children, often accompanied by exaggerated facial expressions and gestures. This form of communication is considered effective in promoting linguistic development in children and strengthening the bond between adults and children.

Findings on adult dogs

Previous research had suggested that using baby talk with puppies enhances their attention. However, this new study from the University of York found that the effect also applies to adult dogs. Researchers used a functional magnetic resonance imaging (fMRI) scanner to monitor the brain activity of trained dogs as they listened to vocal recordings of twelve men and twelve women speaking to either adults or infants. The study found that dogs showed greater brain reactivity to high-pitched speech directed at infants.

Sensitivity to women's speech

Additionally, dogs were particularly sensitive to the speech of women using baby talk. The researchers suggest that the similarity between speech directed at infants and dogs may not be coincidental, and that this sensitivity likely stems from the domestication process and the long history of interaction between humans and dogs.

Recommendations for dog owners

The study authors encourage dog owners to use this style of language when interacting with their pets, as it may help form stronger bonds and increase the likelihood of dogs obeying commands.
