Abstract:
Children as young as 18 months can acquire novel words by overhearing third-party interactions. Demonstrating similar learning processes in nonhuman species would indicate that the social-cognitive skills supporting this process are not exclusively human but may have evolved, or can develop, in other species, offering valuable insights into the origins of language-related cognition. In this study, we demonstrated that a small group of Gifted Word Learner dogs, which possess an extensive vocabulary of object labels, can learn new labels by overhearing their owners' interactions. Moreover, we show that these dogs can acquire novel object-label mappings even when the labels and objects are not presented simultaneously. Taken together, these results suggest that Gifted Word Learner dogs possess sociocognitive skills functionally parallel to those of 18-month-old children.

Generalization, Discrimination, and Extinction
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...
