Final answer:
Interdependence theory and social exchange theory are both theories that explain human relationships, but they have different focuses and approaches.
Step-by-step explanation:
Interdependence theory and social exchange theory are both theories that explain human relationships, but they have different focuses and approaches.
Social exchange theory, as explained by Rusbult and Van Lange, suggests that individuals act as naïve economists and weigh the costs and benefits of forming and maintaining relationships with others.
On the other hand, interdependence theory, also known as complex interdependence theory, focuses on the interconnectedness and mutual dependence among different parts of a system, including nations in international relations.
While social exchange theory emphasizes individual motivations and calculations, interdependence theory takes a broader perspective and examines the interconnections and interdependencies between entities.
