Although research shows that observed behaviours towards a target object can signal psychological ownership to others, we propose that trait cues-specifically, cues of dominance-also inform inferences of psychological ownership. Across four pre-registered studies, we predict and find that another person's trait dominance promotes inferences of psychological ownership for both a tangible (e.
