Abstract. The mere ownership effect is an increase in the subjective value of owned objects compared to identical but non-owned objects. We tested whether the effect differs in magnitude between material and immaterial objects (e.g., information). Three hundred participants played an incentivized detective game in which they had to connect clues to identify a murderer. Their task was to evaluate the usefulness of the clues they or their partners were endowed with. Despite the fact that the immaterial clues were rated as more useful than the material ones, we found the mere ownership effect to be similarly strong for the material and the immaterial clues.

单纯的所有权效应在物质和非物质对象中同样显着

摘要。纯粹的所有权效应是与相同但非拥有的对象相比，拥有的对象的主观价值增加。我们测试了物质和非物质对象（例如信息）之间的影响大小是否不同。三百名参与者玩了一个激励侦探游戏，他们必须连接线索以识别凶手。他们的任务是评估他们或他们的伙伴所拥有的线索的有用性。尽管非物质线索被认为比物质线索更有用，但我们发现，物质线索和非物质线索的单纯所有权效应同样强烈。
