Influence of Social Identity and Personality Traits in Human–Robot Interactions

This study explores the role of social identity in human–robot interactions, focusing on a scenario where a humanoid robot functions as a bartender with either a positive or negative personality. Conducted with 28 participants, the experiment utilized the Big-5 questionnaire to assess personality traits and the Godspeed questionnaire to gauge perceptions of the robot. The research sought to determine if users could perceive the robot’s distinct identities and if these perceptions were influenced by the participants’ personality traits. The findings indicated that participants could effectively discern the robot’s different personalities, validating the potential for programming robots to convey specific social identities. Despite the limited sample size, the results suggest that participants’ initial emotional states and personality traits significantly influenced their perceptions, suggesting that customizing a robot’s identity to match the interlocutor’s personality can enhance the interaction experience. As a preliminary investigation, this study contributes valuable insights into human–robot interaction dynamics and lays the groundwork for future research in the development of socially integrated robotic systems.
