Understanding how dogs remember and distinguish between social partners—whether human or artificial—offers valuable insight into their cognitive and emotional world. In this study published in Animal Cognition, Judit Abdai and colleagues explored dogs’ ability to recognize individuals and recall interactions with both humans and unidentified moving objects (UMOs) designed to mimic social agents.
In the first experiment, dogs interacted with a UMO that assisted them in retrieving an unreachable ball and played with them. When tested after delays of one day, one week, or one month, the dogs did not approach the familiar UMO more quickly than unfamiliar ones. However, during the problem-solving retest, they gazed earlier at the familiar UMO, suggesting memory of the interaction rather than recognition of the individual agent.
The second experiment repeated the design with human partners instead of UMOs. Similar to the first, dogs did not preferentially approach the familiar human but gazed at them sooner during re-testing, again indicating contextual memory without full individual recognition. The findings suggest that short-term encounters are insufficient for developing lasting recognition of individuals, whether human or robotic.
Abdai and colleagues conclude that dogs form general memories of social experiences rather than specific individuals after limited interaction. Long-term individual recognition likely requires more consistent and meaningful exposure, reinforcing the importance of repeated positive interactions in strengthening dog–human bonds.
