Based on research that points to nostalgia as a means of warding off stigmatization, this study suggests that nostalgia triggered by a past encounter with a close immigrant from the in-group can improve attitudes toward out-group immigrants. Focusing on immigration in Greece, 99 university students (M = 23.06, SD = 5.44) participated in the study. Participants who were induced with nostalgia reported higher social connectedness, inclusion of the out-group in the self, out-group trust, and positive out-group attitude compared with participants in the control condition. The aforementioned findings demonstrated that the positive effects of nostalgia about a close in-group member (in this case, a Greek person), who shares an identity with the out-group (being an immigrant), can generalize to the out-group as a whole (immigrants in general). Further implications and future directions on the use of nostalgia as a means of improving attitudes are addressed. Copyright © 2017 John Wiley & Sons, Ltd.
