the minimal group paradigm:
In the minimal group paradigm study related to intergroup behaviors, participants express in-group favoritism when they give more rewards to their own group.
In the minimal group paradigm (overestimators and underestimators) study, participants express in-group favoritism when they give more rewards to their own group. This means that they prefer to give more positive outcomes or rewards to members of their own group compared to members of the other group.
This phenomenon is known as in-group bias, which refers to a preference for one's own group over other groups. In the context of the minimal group paradigm study, participants tend to show in-group favoritism by giving more rewards to their own group.
