Do domestic dogs learn words based on humans' referential behaviour?

Area of Science:

• Canine cognition and behavior
• Animal communication and linguistics
• Comparative psychology

Background:

• Many domestic dogs comprehend human words, yet the learning basis remains unclear.
• Previous research suggests dogs may learn through association, but referential understanding is debated.

Purpose of the Study:

• To investigate if dogs learn object labels via human referential actions, not just simple association.
• To explore dogs' ability to link words to objects using social-pragmatic cues alone.

Main Methods:

• Three studies modeled on infant learning paradigms were conducted.
• Four word-experienced dogs were tested in situations lacking direct word-object contiguity.
• Referential actions, temporally displaced from referents, were the primary social cues.

Main Results:

• No dogs consistently linked object labels with referents using only social-pragmatic cues across all tests.
• One dog demonstrated partial success, suggesting potential for learning via social cues in some contexts.

Conclusions:

• Dogs may not reliably learn object labels solely through social-pragmatic cues in the absence of direct association.
• Limited evidence suggests some dogs might possess nascent abilities for referential learning from social cues.
