Research on the consequences of psychological ownership has mostly focused on its effects on the relationship with a specific target of ownership. But could it be that psychological ownership also has carry-over effects on domains unrelated to the specific target of ownership? A new research by Ata Jami (Northwestern University), Maryam Kouchaki (Northwestern University), and Francesca Gino (Harvard University) examines this question. Specifically, the authors propose that psychological ownership increases prosocial behavior behavior because it boosts people’s self-esteem and therefore makes them more willing to help out. They also identify materialism and mine-me sensitivity as moderators of this effect. This research suggests that psychological ownership besides having profound implications on our relationships with possessions can also affect behavior in unrelated domains, such as altruistic behavior.
