Small Talk with a Robot Reduces Stress

At the last day of the ICSR on September 12, 2025, Katharina Kühne presented her full paper titled „Small Talk with a Robot Reduces Stress and Improves Mood“ (written together with Antonia L. Z. Klöffel, Oliver Bendel, and Martin H. Fischer). Previous research has shown that social support reduces stress and improves mood. This study tested whether small talk with a social robot could be helpful. After performing a stressful task, 98 participants either chatted with a NAO robot, listened to the robot tell a neutral story, or did not interact with the robot. Both robot interactions reduced stress – particularly small talk, which also boosted positive mood. The effects were stronger in participants with high acute stress. Positive affect played a key role in stress reduction, suggesting that robot-mediated small talk may be a useful tool for providing emotional support. Dr. Katharina Kühne and Prof. Dr. Martin H. Fischer are researchers at the University of Potsdam. Antonia L. Z. Klöffel assists Katharina Kühne as a junior scientist. Martin Fischer is the head of the Potsdam Embodied Cognition Group (PECoG). Prof. Dr. Oliver Bendel is an associated researcher with PECoG.
