Key features that stand out in intergroup conflicts:
1) Emotional component: includes negative feelings towards the other group, such as aggression, resentment, prejudice or group psychological tension. These feelings sometimes lead to escalation, group hostility, or social isolation between groups.
2) Cognitive component: includes differences in beliefs and attitudes between groups, such as interpreting events or decisions in a way that matches the interests of one group and diminishes the importance of another.
3) Behavioral component: manifested in the actions and practices of groups towards each other, such as competing for resources, collective punishment, protests, boycotts, or the use of force. It can also manifest itself in cooperation or negotiations, when the conflict is managed consciously and constructively.
