The Role of Empathic Traits in Emotion Recognition and Emotion Contagion of Cozmo Robots

In this online study, we investigated how well people could recognize emotions displayed by video recordings of a Cozmo robot, and the extent to which emotion recognition is shaped by individuals' empathic traits. We also explored whether participants who report more empathic tendencies experienced more emotional contagion when watching Cozmo's emotional displays, since emotion contagion is a core aspect of empathy. We tested participants' perceptions of Cozmo's happiness, anger, sadness, surprise, and neutral displays. Across 103 participants, we report high recognition rates for most emotion categories except neutral animations. Furthermore, the mixed effects modelling revealed that an empathy subtype (the empathic concern subscale from the Interpersonal Reactivity Index) significantly impacted emotional contagion. Contrary to predictions, participants with high empathic concern subscale scores were less likely to find the robot's videos emotionally contagious. The study validates the utility of Cozmo robots to display emotional cues recognizable to human users, and further suggests that empathic traits could shape our affective interactions with robots, though perhaps in a counterintuitive way.

Automated summary

This online study examined people's ability to recognize emotions displayed by a Cozmo robot and investigated how empathic traits influence emotion recognition. The study found high recognition rates for most emotion categories and revealed a significant impact of empathic traits on emotional contagion. Contrary to predictions, participants with higher empathic traits showed lower emotional contagion when watching the robot's videos.
