Answer:Common Ingroup Identity Model
Explanation:common ingroup identity model as a means of reducing intergroup bias. This model proposes that bias can be reduced by factors that transform members' perceptions of group boundaries from “us” and “them” to a more inclusive “we”. From this perspective, several features specified by the contact hypothesis (e.g. co-operative interaction) facilitate more harmonious intergroup interactions, at least in part, because they contribute to the development of a common ingroup identity.
