The article "The State of Psychological Ownership: Integrating and Extending a Century of Research" by Jon L. Pierce, Tatiana Kostova, and Kurt T. Dirks explores the concept of psychological ownership, which refers to the feelings of ownership individuals develop for various objects, both material and immaterial. The authors build upon and extend prior scholarship to provide a conceptual examination of this construct, addressing why and how it arises. The authors define psychological ownership as the state where an individual feels that a target object or part of it is "theirs." This state is characterized by a cognitive-affective relationship between the individual and the object, where the object is experienced as closely connected to the self. They argue that psychological ownership is rooted in three key human motives: efficacy and effectance, self-identity, and having a place to dwell. The article discusses the experiences that give rise to psychological ownership, including controlling the ownership target, coming to know the target intimately, and investing the self into the target. It also explores the consequences of this state, both positive and negative, and provides a foundation for developing a comprehensive theory of psychological ownership. The authors integrate and extend existing literature from various disciplines, including anthropology, psychology, social psychology, and philosophy, to provide a robust conceptual framework. They propose that psychological ownership is influenced by both individual and situational factors, and that the emergence of this state is a complex process involving multiple routes and mechanisms. Overall, the article contributes to the understanding of psychological ownership by offering a systematic and integrative perspective, which can inform future empirical research and theoretical developments.The article "The State of Psychological Ownership: Integrating and Extending a Century of Research" by Jon L.
