Metacognition in dogs: Do dogs know they could be wrong?

Area of Science:

• Animal cognition
• Comparative psychology
• Behavioral science

Background:

• Understanding animal cognition requires investigating their sensitivity to acquired information.
• Previous research with great apes suggests they seek additional information in uncertain situations.

Purpose of the Study:

• To determine if dogs (Canis familiaris) adjust their information-seeking behavior based on their own knowledge of reward location.
• To compare dogs' performance in an information-seeking task with that of great apes.

Main Methods:

• Three experiments were conducted using a V-shaped fence setup with a gap, allowing dogs to choose between direct selection or seeking information.
• Variables included dogs' visual access to baiting, reward type (food vs. toys), food quality, and time delay.
• Behavioral analysis focused on fence selection and information-seeking actions (checking through the gap).

Main Results:

• Dogs increased information-seeking behavior (checking through the fence gap) when they had not witnessed the reward placement.
• Dogs rewarded with toys performed better than those rewarded with food.
• While food quality did not affect accuracy, dogs responded faster to high-quality food rewards; time delay did not increase checking behavior.

Conclusions:

• Dogs, like apes, actively seek information when faced with uncertainty.
• Dogs exhibit less behavioral flexibility in uncertain situations compared to great apes.
• Reward type significantly influences dogs' task performance, with toys being more effective than food in this context.
