Previous research indicates that dispositional worry about potential threats is associated with greater ingroup biases. However, the nature of this relationship within minority cultural groups, and the specificity of which threats matter most for this relationship, remain poorly understood. The current study thus aimed to build on existing work in three key ways: by simultaneously examining the effects of threat in both a mainstream and an immigrant population, by examining associations between threats and cultural practices and real-life interactions, and by addressing whether concerns about disease threats or physical threats were more robust predictors. Thus, we investigated the relative influence of physical- and disease-threat concerns for acculturation and ingroup preferences in both immigrant and non-immigrant Americans ( N = 964, 171 immigrants). Immigrant Americans completed an acculturation survey in which their engagement with their heritage culture was compared with their engagement with mainstream American culture. Meanwhile, non-immigrant Americans responded to similar items assessing their engagement with US versus foreign cultural practices. Results indicated that dispositional worry about physical threats was associated with lower acculturation in immigrant participants, and lower engagement with foreign cultures in non-immigrant Americans. Further, in the combined sample, participants who were more concerned about physical threats were less likely to have had a romantic partner of a different ethnicity than their own. By contrast, dispositional worry about disease threat did not reliably predict cultural engagement or partner choice. These findings are consistent with the hypothesis that physical-threat concern leads to less engagement with foreign cultures.

恐惧文化：对身体（而非疾病）威胁的感知上的个体差异可预测移民和主流美国人的文化新恐惧症

先前的研究表明，对潜在威胁的性格忧虑与更大的群体偏见有关。但是，对这种关系在少数文化群体中的性质以及威胁的特殊性对该关系最重要的了解仍然很少。因此，当前的研究旨在通过以下三个关键方式来加强现有工作：通过同时审查主流人口和移民人口中威胁的影响，通过审查威胁与文化习俗和现实互动之间的联系以及解决是否存在关注等问题来进行研究。关于疾病威胁或身体威胁的预测指标更为可靠。因此，我们调查了身体和疾病威胁问题对移民和非移民美国人的适应和群体偏好的相对影响（N = 964，171个移民）。移民美国人完成了一项文化适应性调查，将他们对遗产文化的参与与对美国主流文化的参与进行了比较。同时，非移民美国人对类似项目做出了回应，评估了他们与美国的接触与外国文化习俗的关系。结果表明，对人身威胁的性格忧虑与移民参加者的文化适应度较低以及非移民美国人对外国文化的参与度较低有关。此外，在合并样本中，更担心人身威胁的参与者与自己的恋爱伴侣相比，拥有不同种族的恋爱伴侣的可能性较小。相比之下，对疾病威胁的性格忧虑并不能可靠地预测文化参与度或伴侣选择。
