我拥有，所以我帮助：心理所有权如何增加亲社会行为（摘要）

    本文探讨了心理所有权的后果，它超越了与拥有物的具体关系，可以指导不相关情况下的行为。在7项研究中，我们发现心理所有权会导致自尊的提升，从而鼓励个体更加利他。此外，我们还表明，心理所有权对利他行为的影响不是由自我效能（Self-efficacy）、感知权力（Perceived power）、互惠感（Reciprocity）、富裕感（feeling well-off）或情感驱动的。唯物主义和所有物-自我敏感度（Mine-me sensitivity，反应所有权在多大程度上决定了个体将特定物体与自我联系在一起的程度）等个体差异能够调节心理所有权对亲社会行为影响，我们发现该效应对物质主义或所有物-自我敏感度低的个体不成立。最后，我们通过关联个体所有物的消极属性，减弱了心理所有权对亲社会倾向的影响。

    This article explores the consequences of psychological ownership going beyond the specific relationship with the possession to guide behavior in unrelated situations. Across seven studies, we find that psychological ownership leads to a boost in self-esteem, which encourages individuals to be more altruistic. In addition, we show that the effect of psychological ownership on prosocial behavior is not driven by self-efficacy, perceived power, reciprocity, feeling well-off, or affect. Examining materialism and mine-me sensitivity as individual differences moderating the effect of psychological ownership on prosocial behavior, we find that the effect does not hold for individuals low on materialism or mine-me sensitivity. Finally, we attenuate the effect of psychological ownership on prosocial tendencies by making the negative attributes of one’s possessions relevant.
