Scientists Stunned by Canine Ability to Learn Words Through Eavesdropping
A groundbreaking study has revealed that certain dogs possess an extraordinary ability - they can learn words and object names simply by overhearing conversations. Researchers at the University for Veterinary Medicine in Vienna have been studying "gifted word learner" dogs, finding that these canine brains can pick up labels from eavesdropped speech with remarkable accuracy.
The researchers used a series of experiments to test their hypothesis, first introducing 10 gifted dogs to new toys and repeating their names multiple times. In the second experiment, family members would pass a toy between each other while using its name, allowing the dog to listen without direct interaction. After training, the team placed the objects in a room alongside familiar toys and asked the dog to retrieve a specific one by name.
The results were astonishing - dogs picked the correct new toy 90% of the time if they had previously heard its name directly, compared to 80% when it was only overheard. This difference is statistically negligible, but what's more striking is that dogs performed better than chance in both scenarios, suggesting an impressive capacity for social interpretation.
Lead researcher Dr Shany Dror explains that the ability to learn labels from eavesdropped speech likely relies on a host of social cognitive skills, including identifying relevant words within conversations and using cues like people's gaze, gestures, and voices. While the dogs' methods may differ from those of human children, who are known for their language acquisition abilities, the researchers are thrilled by the discovery.
The study suggests that this skill is not unique to humans, as it has been observed in other species like bonobos and African grey parrots. However, it was previously assumed that dogs lacked this ability. Dror believes that the skill predates language evolution, implying that our ancestors had a fundamental understanding of complex social interactions before developing language.
The discovery has sparked interest among experts, including Prof Marilyn Vihman from the University of California, Berkeley. While she notes that researchers may have underestimated the simplicity of word learning in infants, it's striking to see dogs exhibiting similar abilities.
