In a groundbreaking study, researchers have found that certain dogs possess the cognitive ability to learn new object labels by overhearing verbal interactions between their owners and others. These "gifted word learner" (GWL) dogs exhibit behaviors strikingly similar to those of 18-month-old human toddlers, sparking hopes for a deeper understanding of canine cognition.
Led by Claudia Fugazza from Eötvös Loránd University in Budapest, Hungary, the study employed an experimental protocol adapted from research on young children. Ten GWL dogs were presented with two new toys and asked to retrieve them using verbal labels ("Can you bring ?"). The dogs demonstrated remarkable accuracy, correctly selecting the correct toy 80% of the time when directly addressed by their owners.
However, when the dogs watched while their owners talked about the toys without directly addressing them, an astonishing 100% of the GWL dogs correctly chose the toys. This suggests that these dogs can learn new object labels simply by overhearing verbal interactions, regardless of whether they are actively participating or passively listening.
In contrast, non-GWL border collies exhibited no evidence of learning when exposed to a similar experimental protocol. Researchers attribute this difference to a preference for novelty in toy selection among typical dogs, rather than the ability to learn object-label mappings.
The findings have significant implications for our understanding of canine cognition and language development. "Our study shows that the socio-cognitive processes enabling word learning from overheard speech are not uniquely human," notes Shany Dror, co-author of the research. "Under the right conditions, some dogs present behaviors strikingly similar to those of young children. These dogs provide an exceptional model for exploring some of the cognitive abilities that enabled humans to develop language."
While the study's results suggest a remarkable capacity for canine learning and social cognition, it is essential to recognize that GWL dogs are extremely rare, making them a valuable subject for scientific investigation into animal intelligence and language acquisition.
