Individuals who have been exposed to and internalized two cultures vary in the degree to which they perceive their cultural identities as compatible (bicultural identity integration; BII). An experiment tested whether nostalgia, an emotion that is prevalent among bicultural individuals, influences BII and does so via acculturation orientation toward the host culture. Participants were originally from Greece, living in other European countries. We instructed them to recall nostalgic or ordinary events either from their host country or home country. We then assessed acculturation orientation and BII. We hypothesized and found that host-nostalgia increased BII both directly and indirectly via a more positive acculturation orientation toward the host culture. The findings extend the literature on factors that facilitate BII, and showcase the potential of nostalgia to improve biculturality.

接触并内化两种文化的个体在不同程度上将自己的文化身份视为兼容的（双文化身份整合； BII）。一项实验测试了怀旧情绪（一种在双文化个体中普遍存在的情感）是否会影响BII，并通过面向宿主文化的适应取向来影响BII。参与者最初来自希腊，居住在其他欧洲国家。我们指示他们回忆起其所在国或母国的怀旧事件或普通事件。然后，我们评估了文化适应取向和BII。我们假设并发现宿主怀旧情绪通过对宿主文化更积极的适应取向直接或间接增加了BII。这些发现扩展了有关促进BII的因素的文献，
