About

David J. Sushil is a pioneering researcher in human-robot interaction, with a primary focus on the psychological and perceptual mechanisms that drive anthropomorphism. His key research area explores how the physical design of robots—their shapes, movement, and structural features—shapes human responses, particularly perceptions of aggression, intelligence, and animation. Sushil’s major contribution lies in framing anthropomorphism not as a mere cognitive bias, but as a functional response to perceived affordances: the action possibilities a robot’s form suggests to a user. His most cited work, "Anthropomorphism of Robotic Forms: A Response to Affordances?" (2005, 29 citations), systematically varied robot bodies along dimensions such as edge type, locomotion method, and number of movement generators, revealing how design cues trigger distinct social judgments. This foundational study has influenced subsequent research in social robotics and design ethics, demonstrating that even subtle morphological changes can dramatically alter user trust and interaction quality. Sushil’s work remains a touchstone for engineers and cognitive scientists seeking to build robots that are both functional and intuitively understandable, bridging the gap between mechanical form and human social cognition.
