The Impact of the Big Five Personality Traits on Human Interaction with Artificial Intelligence and Social Robots

As artificial intelligence (AI) systems and social robots increasingly become part of everyday human environments, understanding the psychological factors that influence human interaction with these technologies is crucial. This study explores the role of the Big Five personality traits—openness, conscientiousness, extraversion, agreeableness, and neuroticism—in shaping user behavior, emotional responses, and perceptions during interactions with AI and humanoid robots. A mixed-methods experimental design was employed, involving ۶۰ participants who completed the NEO-PI-R personality inventory before engaging in structured tasks with both a conversational AI assistant and a socially expressive humanoid robot. Quantitative data, including task completion rates, engagement time, and self-reported trust and satisfaction, were analyzed alongside qualitative insights gathered through post-interaction interviews. Results showed significant correlations between personality traits and interaction styles: extraversion and openness were linked to higher engagement and enjoyment, while neuroticism was associated with anxiety and lower trust. Conscientious participants preferred structured systems, whereas agreeable individuals showed higher empathy and patience toward AI errors. These findings highlight the importance of personality-aware design in developing adaptive AI interfaces that can personalize their behavior based on user traits. The study provides foundational insights for building emotionally intelligent, inclusive, and user-centered AI systems capable of responding to individual psychological profiles, particularly in education, healthcare, and assistive contexts.
