Attributing Social Motivations to Changes in Agents' Behavior and Appearance

To be considered socially intelligent, agents must be able to adjust their behavior to different social contexts. However, those adjustments must be recognized and understood by other agents and humans, particularly to identify the social motivations that triggered such changes. In this work, we report on an experimental study that explores how external observers attribute social motivations to behavior and appearance changes that agents make to adapt to the context. Furthermore, we study how the presence of other agents in the context might impact the attribution of motivations to specific changes. Our results indicate that participants identify agents' appearance changes as more socially and spatially motivated than behavioral changes. Additionally, agents' awareness is rated higher when the agents adjust their physical characteristics compared to behavioral changes.
