Abstract
The present paper investigates a positive, other-oriented moral emotion: group-based gratitude, in reaction to intergroup positive interdependence or outgroup contributions to ingroup’s goals. Three studies support the notion that group-based gratitude plays a role in improving intergroup attitudes between natives and immigrants in the French context. In Study 1, positive intergroup interdependence was associated with group-based gratitude, which in turn was negatively associated with prejudicial attitudes and behavioral intentions. In the last two studies, highlighting historical outgroup contributions elicited group-based gratitude, which in turn reduced prejudice, increased perceived warmth and reciprocity (i.e., helping behavioral intentions), compared to control condition and positive condition. Links with indebtedness and common ingroup are discussed.
