Do Dogs Provide Information Helpfully?

Area of Science:

• Animal Behavior
• Cognitive Ethology
• Canine Communication

Background:

• Dogs exhibit advanced communicative skills with humans, surpassing other species.
• Showing behavior in dogs is intentional and referential, but helpfulness remains unproven.
• Understanding helpful communication in dogs could reveal insights into their grasp of human goals.

Purpose of the Study:

• To investigate whether dogs communicate helpfully, informing humans about targets of human interest.
• To differentiate between self-interest, neophilia, and genuine helpfulness in dogs' showing behavior.
• To explore if dogs consider human relevance and goals when directing attention.

Main Methods:

• Study 1: Assessed dogs' choices between self-relevant objects, human-relevant objects, distractors, and empty containers.
• Study 2: Examined dogs' persistent showing behavior with and without human vocal cues and object relevance.
• Utilized controlled experiments to observe and quantify dogs' directed attention and object selection.

Main Results:

• Dogs' behavior was primarily driven by self-interest, but they showed increased persistence when indicating human-relevant objects.
• In Study 2, human vocalizations and object relevance enhanced dogs' showing behavior persistence.
• Dogs established joint attention, indicating an awareness of the human's focus.

Conclusions:

• Dogs' showing behavior may be influenced by informative motives, suggesting a consideration of human relevance.
• Dogs might indicate object locations based on recognizing them as targets of human search.
• Results support the idea that dogs account for object relevance to humans, without necessarily implying full understanding of human knowledge states.
