Collective ownership threat is the fear of losing control over what is perceived to be owned. In two experimental studies, we examined the intergroup consequences of collective ownership threat in relation to perceived owned territories. First, among a sample of Dutch adolescents (N = 227), we found that infringement of a hangout place owned by a group of friends led to more perceived collective ownership threat (and not symbolic threat), which was in turn related to more marking and anticipatory defending behavior. Second, among a sample of native Dutch adults (N = 338), we found that framing Turkish EU accession as an infringement of the collective ownership of the country led to more perceived collective ownership threat (and not symbolic and economic threat), which was in turn related to more opposition to Turkey’s possible accession. Our findings indicate that collective ownership threat is an important construct to consider in intergroup research.

集体所有权威胁是担心失去对被认为拥有的财产的控制权。在两项实验研究中，我们研究了集体所有权威胁与感知拥有领土有关的集团间后果。首先，在荷兰青少年（N = 227）的样本中，我们发现，侵犯一群朋友所拥有的视频群聊场所会导致更多的集体所有权威胁（而不是象征性威胁），而这反过来又与更多的标记有关和预期的防御行为。其次，荷兰本土成年人的样本中（ñ= 338），我们发现将土耳其加入欧盟归因于对该国集体所有权的侵犯导致更多的感知集体所有权威胁（而不是象征性和经济威胁），而这又与更多地反对土耳其可能加入欧盟有关。我们的发现表明，集体所有权威胁是团体间研究中要考虑的重要结构。
