The Role of Assertiveness in a Storytelling Game with Persuasive Robotic Non-Player Characters
summary
Study uses Emmy robots as two robotic NPC advisors with manipulated pitch rate posture and gaze, running with 64 participants and yielding 1,220 decision points. Robots display high, low or neutral assertiveness; measures include MBTI, PANAS (Penny's), and Godspeed. Results: 84% no-change in decisions, those who do change (16%) are mostly self-reported low-assertive players, low-assertive robots raise more positive emotion, personality-bearing robots persuade more than neutral ones, but assertiveness level alone does not reliably drive decision changes.
